Beam 501B Open Weights, AI Video Playbooks & JS Neural Nets | AX Trend Deep Dive

Reflection Beam, Herk Edit Kit, and handwired mark a week where AI's building blocks went open - free 501B open weights, a free AI video editing playbook, and code compiled into neural nets. This deep dive connects three launches from October 16, 2026: Reflection AI releases Beam weights - the first open model from Reflection: 501B sparse mixture-of-experts, only 23B active per token, Apache 2.0 license, trained over four weeks on 10,500 Nvidia GB300 GPUs with 100M+ trial runs. Its party trick is token efficiency: ~80% on Terminal-Bench 2.1 with ~25K tokens per attempt, about a third of what rivals need. Catch: serving prices still unpublished. https://github.com/roomedia/ax-trend/... Nate Herk's Herk Edit Kit - declares "Opus 5.5 is my video editor" and releases the entire playbook free: 15 skills for coding agents (Claude Code/Codex), transcript-driven cuts, storytelling frameworks, 406 motion-graphics cards, HyperFrames templates built in. Video editing becomes an agent workflow. 🔗 GitHub: https://github.com/nateherkai/herk-ed... https://github.com/roomedia/ax-trend/... chenglou's handwired - a tool that compiles plain JavaScript code into a neural net. 1,444 GitHub stars in just two days. A genuine paradigm flip: models don't just write code anymore, code becomes the model. Proof of concept stage, benchmarks pending. 🔗 GitHub: https://github.com/chenglou/handwired https://github.com/roomedia/ax-trend/... The thread: open weights, open workflows, open experiments. The teams winning right now aren't guarding secrets - they're giving away the playbook and building an ecosystem around it.
