Description: Hi there - Ben from LiveKit here!
If you’re curious about OpenAI’s brand-new Realtime API and speech-to-speech model, check out this hosted playground and play with the model yourself. If you’d like to learn more about how this came together, read on.
If you’re like me, you’ve probably been wondering what novel things a model like this can do in an API setting with unfettered access to the system prompt and other parameters. I’ve been fortunate to have had early access through my work at LiveKit, where we’ve built open-source developer tooling that makes deploying this model in a production app as simple as possible.
I thought it would also be fun to build a “playground” environment, partially to dogfood our own tooling but largely because I just wanted to play with the model. This playground is freely available to anyone to try, and comes loaded up with a bunch of fun demos of the model’s unique capabilities that I’ve put together.
What blew my mind is how much mileage you can get out of the system prompt alone in this API. Here are some use-cases that are at least halfway to a complete MVP:
- “Customer Support”: An complete phone support agent for the playground
- “Spanish Tutor”: A bilingual language-learning demo
- “Meditation Coach”: It can actually pause and resume speech all on its own as it guides you through a meditation routine
Also some fun (and a bit irreverent…) demos of its style and non-verbal capabilities:
- “Smoker’s Rasp”: It can cough and speak like it’s been smoking three packs a day for 30 years (my favorite, lol)
- “Unconfident Assistant”: Umms, buts, and more - surprisingly lifelike
- “Opera Singer”: The best singing demo I’ve been able to compose (but still not quite what they showed off back in May…)
The playground doesn’t store anything anywhere besides your browser but you can share anything fun you put together with a link that encodes your config into URL params.
For now - anyone can use this playground to access the model and give it a spin (session limit 5min). In the coming days when more people have access to the underlying API, I’ll update it to require you bring your own OpenAI API Key.
Lastly - if you’re even more curious how this was built or want to tweak or adapt it for yourself, the whole project and every dependency is open-source (link in footer!).

Description: Hey HN.
I’ve built an AI inbound SDR for websites because I couldn’t find one.
It engages every visitor and can schedule calls, send lead magnets, and help users navigate websites.
it all started when I was looking for a sales chatbot to increase conversions for one of the companies I was previously working with.
I found a few and all of them cost at least a few thousand per month and were built weirdly (bad routing, not actually AI, required humans, bad onboarding, poor UX).
So I’ve decided to build one based on these principles:
Here’s how I implemented this:
The difference between us and others is that we send highly personalised, context-aware messages even before visitors decide to open a chatbot. Compared to other chatbots we have 800-1000% more conversations because we nailed proactive messaging & personalisation.
We’ve since launched it with 10+ companies and 90% of them got 2-5x more conversions and leads from their corporate website.
I’ve enabled a free plan for anyone who wants to try it out and share some feedback.
We have the highest conversion rates and return on investment when I tried other “revenue-generating chatbots”.

Description: Hi HN! I built a side project that is an alternative to ProductHunt called Showcase My Website. To showcase your website on our home page, pay any amount higher than the last person.
After you submit, we use Puppeteer to grab a screenshot of your website, store the image in Mongo, and then display it on the home page. The tough part was getting this all to happen within a couple seconds of the payment going through. Additionally, we added a “History” tab that gives the website a permanent backlink for SEO purposes.
$1 of every showcase goes to Girls Who Code. There will be a monthly report of the donation posted on the website for public record.
I’d love your feedback! We went live a couple hours ago and have made 2 sales so far while we quickly fix the bugs. Excited to see where this goes.

Description: Hey. I built a loan (mortgage) calculator that lets you compare the savings from overpaying your loan with the potential profits from investing those extra funds.
It will help you answer a key question: is it smarter to overpay your mortgage or invest the extra money? See the hard data and make smarter financial choices!
The comparison is simple:
1. Both the overpayer and the investor have the same mortgage. 2. They both spend the same amount monthly. 3. The overpayer overpays the mortgage installments. 4. The investor puts that extra money into investments.
Who comes out ahead after the mortgage is paid off? Who has more $$? See the comparison at https://showloan.info

Description: With a wedding planned in Mongolia and my limited ability to speak the language, I wasn’t able to contribute much to most of the planning. So, I decided to focus my efforts on something I could manage: creating the wedding invitations!
After dedicating around 50 hours to Blender modeling, sound recording/editing, level design, and game development, I crafted unique wedding invitations that were well-received by everyone.
The project is open-source, and you can find the code here:
https://github.com/matusfaro/wedding-invitations
The invitations are built upon the code from bruno-simon.com, which I highly recommend exploring. It provided a quick start with limited time, and I’m thankful for the creative boost it offered.
P.S. The wedding was a success! Hacker News, I wish you could have joined us.

Description: I’ve been recently working on porting standard C library functions to work on the GPU https://libc.llvm.org/gpu/. A colleague of mine suggested using it to run DOOM, so that’s what I did. It runs on both AMD and NVIDIA GPUs and it is completely playable.
This works by targeting C code directly for the GPU via cross-compilation in clang, looks something like this https://godbolt.org/z/hh44a6vKr. The LLVM C library will provide the headers, C library functions, and the kernel that calls the main function, so we only need to compile the DOOM source code targeting my GPU to get an executable. Then it’s just a matter of writing a loader utility to launch this program on the GPU using the appropriate vendor runtime libraries (AMD’s HSA or CUDA).
Now, it’s not entirely on the GPU because we still need the CPU’s operating system to do a few things. The loader utility has a thread continuously scanning some memory for ‘syscall’ requests from the GPU. Currently the only parts running on the CPU for this demo are standard I/O, reading input keys from SDL, and writing the rendered framebuffer to the SDL window. The only modifications made to the DOOM source code itself were done to allow rendering with multiple threads for better FPS.

Description: Hey HN,
After finishing our masters degree, me and my friend dedicated a month to build an AI tool which makes studying engaging and exciting - Athena AI. We went with a very tight deadline, so that we can focus on the essential features and launch quickly, which I would say was a great decision.
During our studies, we realized we didn’t have an ideal AI tool for prepping our exams - so we built Athena, which processes documents (PDFs, DOCx, slides, code and other textual formats) and provides you with flashcards, quizzes, an AI chat interface and customizable summaries.
Since universities and schools are starting during this time of the year, I hope this will be useful for some of you. We’d love to discuss the product and our journey in the comments!

Description: Hello. I am Madhu, a Software Engineer at Resolve AI. We launched our product today and we are thrilled to share it with you all and get feedback: https://resolve.ai/
Our team at Resolve AI comes with a wealth of experience in this space. I was an early contributor to Kubernetes at Google where I worked on Kubernetes and associated technologies for ~6 years. More recently, I was the tech lead for the Kubernetes-based compute platform at Robinhood where my teams were in a number of SEVs per year, not necessarily caused by the platform itself but still supported (pretty much the story of life for Infrastructure Engineers everywhere). Our co-founders, Spiros Xanthos and Mayank Agarwal co-created OpenTelemetry at their previous startup Omnition (acquired by Splunk). More recently, Spiros was the GM and Senior Vice President of Splunk Observability and Mayank was the lead architect for all of Splunk’s observability product lines. We have all lived the problems we are trying to solve.
Resolve is AI for production engineers. Production systems are dynamic and complex. Addressing common production engineering concerns like incident troubleshooting, cloud operations, security, compliance and cost involves painfully piecing together information from many teams (service on-call rotations, Platform, SRE, etc) and multiple (routinely 10+) different tools (observability, CI/CD, infrastructure, paging, chat, etc). These tools were not designed to work together, pushing the complexity on humans.
Resolve AI is tackling this challenge by building an AI Production Engineer with the goal of automating the majority of tasks across incident management, cloud operations, security engineering, compliance, and cost management. As the first step in our ambitious journey, we are automating incident troubleshooting as it is the most direct way to prevent outages and improve reliability while relieving engineers from the most stressful part of their job. Our goal is to automate the resolution of 80%+ of alerts and incidents without human involvement.
Resolve AI automatically maps and keeps up-to-date a complete knowledge graph of any production environment, without needing any upfront training or user input. It builds knowledge of which tools and signals are relevant for any situation. It comes pre-built with models for various tool categories such as metrics, logs, traces, alerts, seamlessly connecting with category- and vendor-specific products like Prometheus, Splunk, GCP, AWS, Azure and others. These models automatically and continuously adapt to each customer’s environment.
With the state-of-the-art reasoning engine that’s composed of multiple agents, Resolve AI is able to investigate novel incidents, accurately determine causality, learn and adapt as it encounters new situations and perform various complex actions.
Generative AI is inherently probabilistic and not always 100% accurate. Without full context, AI models may hallucinate, potentially misleading users. For an AI that takes actions, building user trust is paramount; it must present clear evidence for any decision or action. We address these challenges by building an interface that supports claims with evidence, present findings with context and allow humans to collaborate with the system so that they can guide the system when needed.
Our video demo is on the website. Please take a look. We really appreciate your feedback. We are also happy to hop on a call to show a demo live if you are interested ([email protected]).

Description: Hi HN,
We’re Brendan and Michael, the creators of Sourcebot (https://github.com/sourcebot-dev/sourcebot). Sourcebot is an open-source code search tool that allows you to quickly search across many large codebases. Check out our demo video here: https://youtu.be/mrIFYSB_1F4, or try it for yourself on our demo site here: https://demo.sourcebot.dev
While at prior roles, we’ve both felt the pain of searching across hundreds of multi-million line codebases. Using local tools like grep were ill-suited since you often only had a handful of codebases checked out at a time. Sourcegraph (https://sourcegraph.com/) solves this issue by indexing a collection of codebases in the background and exposing a web-based search interface. It is the de-facto search solution for medium to large orgs, but is often cited as expensive ($49 per user / month) and recently went closed source (https://news.ycombinator.com/item?id=41296481). That’s why we built Sourcebot.
We designed Sourcebot to be:
- Easily deployed: we provide a single, self-contained Docker image (https://github.com/sourcebot-dev/sourcebot/pkgs/container/so…).
- Fast & scalable: designed to minimize search times (current average is ~73ms) across many large repositories.
- Cross code-host support: we currently support syncing public & private repositories in GitHub and GitLab.
- Quality UI: we like to think that a good looking dev-tool is more pleasant to use.
- Open source: Sourcebot is free to use by anyone.
Under the hood, we use Zoekt (https://github.com/sourcegraph/zoekt) as our code search engine, which was originally authored by Han-Wen Nienhuys and now maintained by Sourcegraph (https://sourcegraph.com/blog/sourcegraph-accepting-zoekt-mai…). Zoekt works by building a trigram index from the source code enabling extremely fast regular expression matching. Russ Cox has a great article on how trigram indexes work if you’re interested: https://swtch.com/~rsc/regexp/regexp4.html
In the shorter-term, there are several improvements we want to make, like:
- Improving how we communicate indexing progress (this is currently non-existent so it’s not obvious how long things will take)
- UX improvements like search history, query syntax highlighting & suggestions, etc.
- Small QOL improvements like bookmarking code snippets.
- Support for more code hosts (e.g., BitBucket, SourceForge, ADO, etc.)
In the longer-term, we want to investigate how we could go beyond just traditional code search by leveraging machine learning to enable experiences like semantic code search (“where is system X located?”) and code explanations (”how does system X interact with system Y?”). You could think of this as a copilot being embedded into Sourcebot. Our hunch is that will be useful to devs, especially when packaged with the traditional code search, but let us know what you think.
Give it a try: https://github.com/sourcebot-dev/sourcebot. Cheers!

Description: Hey it’s Hassaan & Quinn – co-founders of Tavus, an AI research company and developer platform for video APIs. We’ve been building AI video models for ‘digital twins’ or ‘avatars’ since 2020.
We’re sharing some of the challenges we faced building an AI video interface that has realistic conversations with a human, including getting it to under 1 second of latency.
To try it, talk to Hassaan’s digital twin: https://www.hassaanraza.com, or to our “demo twin” Carter: https://www.tavus.io
We built this because until now, we’ve had to adapt communication to the limits of technology. But what if we could interact naturally with a computer? Conversational video makes it possible – we think it’ll eventually be a key human-computer interface.
To make conversational video effective, it has to have really low latency and conversational awareness. A fast-paced conversation between friends has ~250 ms between utterances, but if you’re talking about something more complex or with someone new, there is additional “thinking” time. So, less than 1000 ms latency makes the conversation feel pretty realistic, and that became our target.
Our architecture decisions had to balance 3 things: latency, scale, & cost. Getting all of these was a huge challenge.
The first lesson learned was to make it low-latency, we had to build it from the ground up. We went from a team that cared about seconds to a team that counts every millisecond. We also had to support thousands of conversations happening all at once, without getting destroyed on compute costs.
For example, during early development, each conversation had to run on an individual H100 in order to fit all components and model weights into GPU memory just to run our Phoenix-1 model faster than 30fps. This was unscalable & expensive.
We developed a new model, Phoenix-2, with a number of improvements, including inference speed. We switched from a NeRF based backbone to Gaussian Splatting for a multitude of reasons, one being the requirement that we could generate frames faster than realtime, at 70+ fps on lower-end hardware. We exceeded this and focused on optimizing memory and core usage on GPU to allow for lower-end hardware to run it all. We did other things to save on time and cost like using streaming vs batching, parallelizing processes, etc. But those are stories for another day.
We still had to lower the utterance-to-utterance time to hit our goal of under a second of latency. This meant each component (vision, ASR, LLM, TTS, video generation) had to be hyper-optimized.
The worst offender was the LLM. It didn’t matter how fast the tokens per second (t/s) were, it was the time-to-first token (tfft) that really made the difference. That meant services like Groq were actually too slow – they had high t/s, but slow ttft. Most providers were too slow.
The next worst offender was actually detecting when someone stopped speaking. This is hard. Basic solutions use time after silence to ‘determine’ when someone has stopped talking. But it adds latency. If you tune it to be too short, the AI agent will talk over you. Too long, and it’ll take a while to respond. The model had to be dedicated to accurately detecting end-of-turn based on conversation signals, and speculating on inputs to get a head start.
We went from 3-5 to <1 second (& as fast as 600 ms) with these architectural optimizations while running on lower-end hardware.
All this allowed us to ship with a less than 1 second of latency, which we believe is the fastest out there. We have a bunch of customers, including Delphi, a professional coach and expert cloning platform. They have users that have conversations with digital twins that span from minutes, to one hour, to even four hours (!) - which is mind blowing, even to us.
Thanks for reading! let us know what you think and what you would build. If you want to play around with our APIs after seeing the demo, you can sign up for free from our website https://www.tavus.io.

Description: Hey HN, we’ve been working on Joystick, a remote configuration management platform designed to take the pain out of managing many configs across multiple environments. We’re especially suited for mobile game live-ops, but also have early users from food-tech, edu-tech and gen AI. Our goal is to enable better decoupling of configuration from the app code / repos so config updates can rolled out quickly, and products can be more agile.
It started as something simple, and took on a life of its own. We do dog-food it for our own projects as well. Check our docs for full feature list.
Having a lot of remote configs may not be for everyone, but we wanted to build a tool that embraces this.
Love any feedback, questions and suggestions!

Depending on the complexity of a Zod schema, the resulting validation error message can contain a wall of JSON text - the serialised issues that were recorded during validation.
I wanted to try and create a small tool to help me better visualise and parse these errors. In code and the command line, we do also have the ability to pretty-print the errors but I still wanted a web UI which can let me share URLs for visualised errors.

Description: Hey HN! Victor here from SignatureAPI (https://signatureapi.com)
SignatureAPI is an electronic signature platform via API. Our customers use SignatureAPI to add electronic signatures to their apps and workflows.
SignatureAPI was born out of the frustration of a friend of mine who needed to integrate electronic signatures into his app, but found Docusign API, at $1+ per envelope, too expensive for his use case. We quickly realized that many others shared this same frustration.
We are different from other platforms such as Docusign, Dropbox Sign, Adobe Sign, etc in two key ways:
1. API-First. We are focused on the ease of integration and the developer experience (we are proud of our docs). With SignatureAPI, the API is not a second-class citizen to the UI. The API is the product.
2. Pricing. Our pricing ranges from $0.10 to $0.25 per envelope. Compare that to Docusign API at $1.25–$4.80, Dropbox Sign API at $1.50–$2.50, or Adobe Sign API at $1.80–$2.50.
Our electronic signatures are legally binding in many places, including the US and the EU. The legal foundation of SignatureAPI was developed by a top team of electronic signature lawyers. (And yes, we have the “green checkmark” in Acrobat).
We’d love to hear your honest feedback—likes, dislikes, feature requests—whatever you’ve got.

Description: This is an MVP to reverse engineer Uniswap V2 and forks logic to simulate how much a token can pump with given injection amounts ($10K - $10M). Useful tool to understand how much potential a token has regardless of market cap.
How PumpaNomics Works PumpaNomics uses the Constant Product Formula, which is the basis for many decentralized exchanges like Uniswap V2 and their forks. Here’s how it works:
Liquidity Pool: The pool contains two tokens, each representing half of the total liquidity value. Constant Product: The product of the two token quantities always remains constant k = x * y. Price Impact: Adding one token to the pool (buy pressure) increases x and decreases y to maintain the constant k. Price Calculation: The price is determined by the ratio of the two tokens Price = y / x. Price Increase: As x increases and y decreases, the price of the token being bought rises. PumpaNomics Accuracy: For more realistic results, PumpaNomics uses combined liquidity across all onchain pools in its calculations, accounting for factors like arbitrage and market depth.
Key Insight: The constant product formula exhibits a quadratic relationship between liquidity and price. Doubling the liquidity (100% increase) results in a 4X price increase. This quadratic nature means that price changes are more dramatic than linear relationships. Here’s why:
Initial state: x = y = √k After doubling x: new_x = 2√k, new_y = k/(2√k) = √k/2 New price ratio: (√k/2) / (2√k) = 1/4 of the original ratio This means the price of the token being bought is now 4 times higher

Description: agentmaxx is an AI agent that analyzes your facial attractiveness based on a variety of health-based parameters, then offers personalized tips to improve
a social mechanism is involved as well (live chat, peer analysis, and more)
backstory —
the idea for agentmaxx came about while brainstorming potential use cases for AI image comprehension
a silly and potentially unhealthy gen-z tiktok trend “looksmaxxing” became popular several years ago, the theme was to improve facial attractiveness via various facial exercises and general facial hygiene
agentmaxx is an implementation of that meme into a (potentially?) useful direction
could an AI agent assess your facial health based on simple parameters with detailed breakdowns of the ratings, then provide personalized, actionable tips to improve each metric?
to take this beyond a simple demo/toy, i implemented a social aspect as well, with the following mechanism:
- when a selfie is uploaded, it is inserted into the queue
my optimistic (likely naive) hope is that the social aspect would not be a source of trolling and toxicity
next on the roadmap for agentmaxx is account creation, where users can get analyzed privately and track how their ratings change over time
while i continue to brainstorm and launch similar AI image comprehension products, my eyes are set on the possibilities that AI video comprehension hold
please feel free to reach out or comment with your ideas!

Description: Hey everyone, just wanted to share a tool I’ve been working on.
It’s a chrome plugin to extract Lists & Page Details from any website.
Here’s a preview: https://www.youtube.com/watch?v=ZyFFhilcGBo
Backstory:
A few months ago I was toying with the idea of building a no-code scraper. I shared a prototype on twitter and it blew up, so I continued working on it.
This is how PandaExtract was born.
Originally I was aiming to build a full web scraper but slowly realized that trying to cover every scraping need is just too complex. So I niched it down to a very specific use case: List + Page Details.
What it can do now: * Extract Lists instantly * Extract Page Details using AI models (best for small data that can fit into a spreadsheet)
Who is it meant for? This is not meant to replace more traditional scraping operations but rather allow people to quickly grab some structured data from websites.
Most common use cases are reviews extraction, phone numbers, local business lists, product lists…
Pricing:
Most of the plugin is Free but there are some PRO features.

Description: pov: you want to be logged into gmail but not fkn google.com. in fact you wish you were never automatically logged in while using google.com. esp if you use a chrome profile.
what’s prixi?
* it’s a proxied version of google search
why you might want it:
* keeps your searches more private
it’s dockerized, so super simple to get running. perfect for that raspberry pi or old laptop you’ve got lying around.
check it out on github: https://github.com/oeo/prixi
i mainly made this for my homelab so i could just create an lxc and expose it over proxmox. my plan is to support transparent http proxies soon via the config file so you can have an entirely different ip just by throwing up an instance of tinyproxy or something on an ec2 micro.
i’d love to hear your thoughts, feedback, or suggestions for improvement.

Description: Hey everyone,
I wanted to share a little side project I developed recently called Crumly. It’s an app aimed at generating instant 3D visuals for design ideas, especially for those who work in physical/spatial design like architects, interior designers, and set designers.
The idea behind Crumly is to make it super easy to create quick, clear visuals from any 3D model in just a few seconds. The goal is to help communicate design ideas more effectively, especially in the early stages when it’s more about exploring different concepts rather than focusing on highly detailed, polished models.
I’ve seen (and experienced) frustration with the clunky, time-consuming process of translating design ideas into 3D models. The tools available can really bog down the creative process and require a lot of effort, not to mention the costs involved. Plus, if the project scope changes, a lot of that work ends up going to waste.
With Crumly, I’m trying to explore whether generative systems could help make that process smoother, especially for those early conceptual phases when quick, low-fidelity visuals are needed to convey a design’s direction. It’s meant to complement high-end modelling tools by offering a faster, more intuitive way to generate and communicate ideas. You can develop a low-effort, low-fidelity modeling in any tool of your choice (provided it exports one of the commonly used 3D formats) and experiment with visual creativity in this AI supplemented canvas. There are some basic tools for last-minute refinements as well.
The inspiration for this came from discussions with colleagues who work in virtual environments. They currently use midjourney generations next to block models of the actual sets to explain their designs to the production team. We started thinking about how to give more control in shaping the visual output of the 3D model. It’s still in the early stages, but I’m excited about the potential of the approach and keen to see where it goes.
The web-app might hit limits on the model-size, so please be gentle with the number of triangles when you are experimenting. It also doesn’t help to have very complicated models with this tool.
Also images generated is public by default for now. Uploaded models are isolated and safe.
I’d love to hear your thoughts, and if anyone is interested in giving Crumly a try, feel free to reach out!

Description: I’ve made an app called Flame It Up. Here’s why I made it and how it’ll help ease the pain of launching your next products.
Problem: When you’re building and launching new products, it’s hard to keep track of and find the directories you should be launching on, and it’s even harder to tell if you’ve launched there or not, especially when you’re just starting to ship products.
As a founder, it’s important to be able to easily launch on all the major platforms and track those launches between your projects.
Solution: I started making a list of where I should launch my next projects and added data like traffic information or domain ranking to help me prioritise my launches.
I thought maybe I could make an app out of it. So I did, and Flame It Up was born. It includes a database of quality directories where you can launch your product with some metrics like DR and traffic, as well as opinionated metrics like importance, based on my experience.
This app also allows you to track your launches across different projects and keep track of your launch progress in different directories. I’ve designed it to simplify the process so you can focus on what matters—building great products, not researching where to launch them.
Would love to hear your feedback :)

Description: I have recently created a program to watch anime from cli. You can stream any anime you want and the latest watched episode would be updated on anilist. You can have Discord RPC showing what anime you are watching with anime cover. You can also skip the Intro and Outro of the anime with this program. The playback speed of your player would also be saved so you dont have to change the speed for each episode. I would be adding new features to this program very soon.

I’m working on a fun project that brings together fantasy football and a bit of nostalgia! I built a fantasy football interface that’s styled to look like the classic Windows XP operating system. The whole experience leverages React Draggable to give it that early 2000s feel.
Let me know what you think, and I’d love any feedback on improving the experience or ideas for features I should add!
Thanks for checking it out!

Description: The best way to understand how GenAI adoption will evolve over time is by looking at how mature AI teams at big tech companies are applying it today.
A couple of weeks ago, I launched a fully automated podcast, AI Arxiv that focuses exactly on this. I have built an automated pipeline that does the research for this podcast by sifting through various sources such as engineering blogs, research papers, youtube videos etc., extracts high signal content, categorizes it and feeds it to Google’s NotebookLM for audio generation before getting published on public RSS feeds, Spotify and Apple podcast. I continue to be fascinated by how AI is being applied in novel ways beyond chatbots for solving unique use cases.
The podcast has already crossed 40 episodes, 50 subscribers and 500 listens. Some of the more popular ones include:
- How Meta uses LLMs for efficient incident response
- How Salesforce operationalizes models at scale
- How DoorDash built a high quality RAG for dasher support
- How Pinterest built text-to-sql
I was glad to hear from some folks that this was helping them stay on top of novel GenAI use cases and also to stretch their thinking beyond chatbots. The nice thing is, these podcast episodes are semi-automated with myself in the loop directing and approving workflows. As a result, it hardly takes few minutes to generate and publish new episodes.
For the tech stack, I used CrewAI for content research, DSPy for content metadata & podcast notes/sponsor message and Langtrace for experimentation & testing.
If you are someone actively tinkering with LLMs or even generally curious about the GenAI space, do check it out.
