September is Transit Month: Join us to Celebrate 10 Years and 100 Miles of Muni Forward
By Nia Evans

Transit Month is coming up – learn how you can celebrate. September is right around the corner, and it's a special time here at the SFMTA. It's Transit Month! We've been preparing for an engaging month of celebrations dedicated to public transportation. And this year stands out because it's also the 10th anniversary of Muni Forward. Since 2014, we've built 100 miles of improvements through our Muni Forward program. The goal: make Muni the best way to get around the city. These upgrades have reduced wait times, increased ridership and improved safety citywide. We're looking forward to...

Show HN: Repo2vec – an open-source library for chatting with any codebase https://ift.tt/42bVX39

Show HN: Repo2vec – an open-source library for chatting with any codebase Hi HN, We're excited to share repo2vec: a simple-to-use, modular library enabling you to chat with any public or private codebase. It's like Github Copilot but with the most up-to-date information about your repo. We made this because sometimes you just want to learn how a codebase works and how to integrate it, without spending hours sifting through the code itself. We tried to make it dead-simple to use. With two scripts, you can index and get a functional interface for your repo. Every generated response shows where in the code the context for the answer was pulled from. We also made it plug-and-play where every component from the embeddings, to the vector store, to the LLM is completely customizable. If you want to see a hosted version of the chat interface with its features, here's a link: https://www.youtube.com/watch?v=CNVzmqRXUCA We would love your feedback! - Mihail and Julia https://ift.tt/n6lIHuM August 29, 2024 at 01:29AM

Show HN: Warehouse OpenAI requests to your own database https://ift.tt/5IZzVGb

Show HN: Warehouse OpenAI requests to your own database Today we’re launching Velvet, an AI gateway for warehousing OpenAI and Anthropic requests to your PostgreSQL instance. We originally built an AI SQL editor, but realized that customers were using it to monitor their AI requests in production. We had already built an AI request warehousing tool internally to debug our SQL editor and gave some customers access. A few days into testing this idea, our pilot customer launched [1] and we began warehousing 1,500 requests per second. We worked closely with their engineering team in the following weeks, completely re-architecting Velvet for scale and additional features (such as Batch support). Along the way, other companies began seeking out Velvet to get visibility into their own LLM requests. We’re launching our AI gateway as a self-serve product today, but our pilot customers are already warehousing over 3 million requests per week - so the system is stable and performant. What makes Velvet unique is that you own the data in your own database. Also, we’re the first proxy that gives visibility into OpenAI batch calls - so you can observe and monitor async calls that save you money. Some technical notes: - Supports OpenAI and Anthropic endpoints - Data is formatted as JSON and logged to your own PostgreSQL instance (can add support for other databases for paying customers). - You can include queryable metadata in the header, such as user ID, org ID, model ID, and version ID. - Built on Cloudflare workers, which keeps latency minimal (using our caching feature will reduce latency overall) - Built for security + starting process of SOC II soon Why warehouse your requests? - Understand where money is spent. Use custom headers to calculate the cost per customer, model, or service. - Download real request/response data, so you can evaluate new models (e.g., re-running requests with a cheaper mini model) - Monitor time to completion of batch jobs. (e.g., OpenAI says 24 hours, but our customers average 3-4 hours) - Export a subset of example requests for fine-tuning It’s just a 2 line code change to get started.

Show HN: Live Subtitles for Any App on Mac https://ift.tt/rfX0qpZ

Show HN: Live Subtitles for Any App on Mac I’m non-native English Speaker and i’m so tired of saying “Say it again” on online calls. Especially if it is Indian or Scottish Accent. And moreover if it is some really serious interview. That’s why i built Subtitly - Live Subtitles for any app on macOS. Few things about subtitly: - Subtitles are in Mac’s notch ⇒ you always look into the camera - They are really fast and reliable (2-3% Word Error Rate) - On-device AI ⇒ Offline & Private - Works in any app ⇒ Watch twitch streams with subs or calls in discord with subs. Here is the demo how it works: https://ift.tt/wsB4vA1 August 27, 2024 at 09:24PM

Show HN: Built a simple Hacker News client with Expo Pretty easy to start building native apps with expo these days, especially with prior Web and React knowledge. Did this over a few weekends while learning about Mobile development, their docs are a big help too. https://ift.tt/QFkHfui August 27, 2024 at 06:13PM
