MARS5, open-source, insanely prosodic TTS model
Hey guys, This is Akshat from CAMB.AI. Today's we're super pumped to introduce MARS5, a fully open-source (commercially usable) TTS with break-through prosody and realism available on our Github: https://www.github.com/camb-ai/mars5-tts Watch our release demo here: https://www.youtube.com/watch?v=bmJSLPYrKtE Why is it different?

In plain words
MARS5 is an open-source text-to-speech model that generates speech in over 140 languages with advanced prosody control. It uses 2-3 seconds of audio reference to replicate speaking styles, handling demanding scenarios like sports commentary, movies, and anime. Designed for researchers and developers, MARS5 is commercially usable and available on GitHub for research and creative applications.

MARS5 is able to replicate performances (from 2-3s of audio reference) in 140+ languages, even for extremely tough prosodic scenarios like sports commentary, movies, anime and more; hard prosody that most closed-source and open-source TTS models struggle with today. We're excited for you to try, build on and use MARS5 for research and creative applications. Let us know any feedback on our Discord: https://discord.gg/ZzsKTAKM

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
