OneCLI (YC S26) is an open-source sandboxed agent harness designed for teams. It operates under an Apache-2.0 license, with the exception of enterprise features located in `ee/` directories. These enterprise features are governed by the OneCLI Enterprise License, which permits free use for development, testing, and evaluation, but requires a subscription for production use. All other components are Apache-2.0 licensed and can be self-hosted in production without a commercial license.

A developer trained a 125M-parameter transformer model to autocomplete piano performances in real time, achieving approximately 108 notes/sec on an iPhone 15. Key improvements stemmed from optimizing the MIDI representation, aggressive data cleaning, and implementing DPO post-training. Pairwise evaluation using Gemini 3.5 Flash helped build a preference dataset for DPO, by asking it to compare continuations rather than assign absolute scores, and mirroring comparisons to reduce position bias.

London-based Callosum, a startup specializing in software that matches AI tasks with various models and chips, successfully raised a $100M seed funding round. The investment came from several sources, including Atomico and the UK Sovereign AI Fund, among others. This funding will support Callosum's continued development in optimizing AI task allocation across different hardware and software configurations.

Poolside AI, an artificial intelligence model-building startup, has reportedly secured a non-exclusive $6 billion licensing deal with Nvidia.
