Modus, serverless framework for intelligent APIs powered by WebAssembly
Modus is an open-source, serverless framework for building APIs powered by WebAssembly. It simplifies integrating AI models, data, and business logic with sandboxed execution. We built Modus to put code back at the heart of development. You write a function. export function sayHello(name: string): string { return `Hello, ${name}!`; } Then, Modus: - extracts the metadata of your functions - compiles your code with optimizations based on the host environment - caches the compiled module in memory for fast retrieval - prepares an invocation plan for each function - extracts connections, models,…
In plain words
Modus is an open-source, serverless framework that builds APIs using WebAssembly. Developers write functions that Modus automatically compiles, optimizes, and deploys with sandboxed execution environments. It streamlines integrating AI models, data, and business logic into APIs by handling metadata extraction, module caching, and endpoint generation. The framework targets developers who want to focus on writing code while Modus manages the infrastructure and compilation layers.

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…
