Heygem AI – An Open Source, Free Alternative to Heygen AI

We’ve open-sourced Heygem, a fast and free alternative to Heygen. It generates photorealistic AI avatar videos from a photo and voice — no training, no watermark, runs locally on 8GB GPUs, and supports 4K output. Ideal for developers building AI avatar pipelines with minimal setup. Built by the team behind duix.com. Feedback and contributions welcome!

In plain words

Heygem AI is an open-source tool that generates photorealistic avatar videos from a photograph and audio input without requiring model training or adding watermarks. It runs locally on standard 8GB GPUs and supports 4K output, making it suitable for developers integrating AI avatar generation into their applications. The software is designed for minimal setup and is available free for use and modification.

  • I trained a 125M model to autocomplete piano on-device▲598

    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.

  • Needle2: 14MB agentic LLM for phones, wearables, smart home and robots▲537

    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…
