Show HN: Audiopipe – Pipeline for audio diarization, denoising and transcription Audiopipe is a one-liner for denoising, diarization and transcription with demucs + pyannote + insanely-fast-whisper. Made it to transcribe podcasts and Dungeons And Dragons sessions, figured it could be useful. It also has a wasm UI to load transcriptions and audio. Feel free to contribute! Feedback appreciated. https://ift.tt/3oQCA7z July 1, 2025 at 02:32AM

Show HN: Attach Gateway – one-command OIDC/DID auth for local LLMs We’ve been building local and on-prem agent workflows for open-source LLMs. Engines like Ollama or vLLM ship with no auth, so every team ends up writing the same JWT proxy. Attach Gateway is a single process that sits in front of any model server and handles the boring bits: - verifies OIDC / DID JWTs - adds X-Attach-User and X-Attach-Session headers so downstream agents share the same identity - optional /a2a/tasks/send endpoint for Google-style A2A hand-offs - mirrors prompts + completions to Weaviate (runs in Docker) One `pip install attach-dev`, export a token, run `attach-gateway`, and your local Ollama is protected in under 60 seconds. Repo: https://ift.tt/hbFTILX PyPI: https://ift.tt/Lhbo49M Would love feedback – especially from teams doing multi-agent or on-prem work. https://ift.tt/hbFTILX July 1, 2025 at 01:08AM

Show HN: QuizKnit, an open source quiz creator QuizKnit is an open source quiz creator to create quizzes by pasting in text or selecting from a large range of historical categories. Started as a very simple app for me to play around with OpenAI’s API last year then morphed into a portfolio project during my job search earlier this year. Now happily employed so decided to open source it. Right now, a user can create a quiz, take a quiz, save it and share the quiz with other people using a URL. You can try out the full working application at https://quizknit.com Github Links: Frontend: https://ift.tt/YuoLQKD , Backend: https://ift.tt/pBSwEAM https://quizknit.com July 1, 2025 at 12:16AM

Show HN: Sharpe Ratio Calculation Tool I built a simple but effective Sharpe Ratio calculator that gives the full historical variation of it. Should I add other rations like Calmar and Sortino? https://ift.tt/jydXF4f June 30, 2025 at 12:38AM

Show HN: A tool to benchmark LLM APIs (OpenAI, Claude, local/self-hosted) I recently built a small open-source tool to benchmark different LLM API endpoints — including OpenAI, Claude, and self-hosted models (like llama.cpp). It runs a configurable number of test requests and reports two key metrics: • First-token latency (ms): How long it takes for the first token to appear • Output speed (tokens/sec): Overall output fluency Demo: https://llmapitest.com/ Code: https://ift.tt/mGRyEIa The goal is to provide a simple, visual, and reproducible way to evaluate performance across different LLM providers, including the growing number of third-party “proxy” or “cheap LLM API” services. It supports: • OpenAI-compatible APIs (official + proxies) • Claude (via Anthropic) • Local endpoints (custom/self-hosted) You can also self-host it with docker-compose. Config is clean, adding a new provider only requires a simple plugin-style addition. Would love feedback, PRs, or even test reports from APIs ...

Show HN: Query your Rust codebase and generate types for anything Hello HN! As a long-time professional Rust developer. I've always been frustrated by the difficulty and "hackiness" of producing bindings to other languages, whether a frontend, an FFI library, etc. Not just in Rust but in any language. After many years of trying existing solutions and trying to make my own, I've finally developed a solution I'm very happy with. RTK (aka Rust Type Kit) allows you to write Lua scripts that perform queries on your code, such as method calls to Axum's `.route`, function definitions, and more, and then receive rich type information including all argument types, function paths, proc macro attributes, and more. Your Lua script can then read this information and emit an output file in any language of your choosing. Or, you can emit compiler errors and use it as a linter of sorts. You can even directly re-emit Rust code itself and use this as a richer proc macro solutio...
