The Rise of the AI Software Engineer: Jesse Han

Feb 5, 2025 · 3:48

Jesse Han, CEO of Morph Labs, announces the Morph Code Index and RiffCoder 7B model as milestones toward the personal AI software engineer. The Code Index is a neurosymbolic code database that enables semantic search over codebases, makes entire Git history visible to coding assistants, and transmutes code into training data. It uses static analysis, vector embeddings, and graph algorithms for state-of-the-art code search, with a query language guaranteeing precise results. RiffCoder 7B, trained on data from the Code Index, is the only open-source code editing model that runs on laptops and IDEs. Morph Labs is building a platform for managing personal AI software engineers, available via waitlist. The future of software should belong to everyone, and the tools are open-source and free.

Building AI For All: Amjad Masad & Michele Catasta

Amjad Masad and Michele Catasta announce Replit's AI for all, giving free AI-powered coding to millions of users. They detail the training of Replit Code v1.5, a 3.3B parameter model trained on 1 trillion tokens of code, which outperforms StarCoder 3B and approaches Code LLaMA 7B in Human Eval despite being half the size. The model is optimized for low-latency inference, generating over 200 tokens per second per GPU. Catasta explains the data pipeline using permissively licensed code from The Stack and Replit public repos, with five epochs of repeated high-quality data. The model is released open-source with a commercially permissive license. Partnerships with Glaive AI for instruction fine-tuning, Morph Labs for a novel fill-in-syntax-tree format, and Perplexity for fast model serving are also unveiled.
