GitHub Next opens LocalJev: local Jev-compatible decision API on oMLX
GitHub Next open-sourced LocalJev (github.com/githubnext/localjev): a morning build of a “poor man’s Jev” for teammates without TypeSafe Jev access. It exposes a Jev-compatible POST /v1/systemone API in Bun/TypeScript, defaults to oMLX-backed local models such as DiffusionGemma, and reports evals across DiffusionGemma, Qwen MoE, Gemma 4 MoE, and Gemma 4 e4b/e2b (benchmark report in-repo). The LocalJev server works with normal Jev client wrappers, but probabilities are model-reported rather than logit reads—calibrate before consequential use.

Zed Delta Public Beta: Multiplayer Agent Coding With Changes Tied to Conversation Threads
Zed launched Delta into public beta: a multiplayer environment for coding with agents and reviewing what they build, with every code change linked to the conversation that produced it. Downloads are available today for macOS, Linux, and Windows. Zed has already stopped opening GitHub PRs on the Delta repo and lands changes with Delta itself via guided review and /land.

Microsoft Research and UC Berkeley open-source TokenEconomizer, a plugin that cuts Claude Code and Codex costs by 18.4–30.9% on SWE-Bench without changing the agent
Microsoft Research, Microsoft Security and UC Berkeley open-sourced TokenEconomizer on GitHub (Apache 2.0, v0.1.0 released October 26), a plugin for Claude Code, Codex, GitHub Copilot CLI and Pi, with experimental opencode support. It learns from earlier sessions in the same repository: micro-skills remember repo facts, tool pruning drops tool definitions that go unused, and a loop guard nudges an agent that is stuck. The paper reports 18.4–30.9% lower mean cost across five agent and model combinations on 277 SWE-Bench tasks (paper figures).
