AISummary of 1 article

Microsoft Research and UC Berkeley released TokenEconomizer, an open-source plugin that learns from past sessions to reduce coding agent spending.

On 277 SWE-Bench tasks, MarkTechPost reports, it lowered mean cost by 18.4% to 30.9% across five agent-model settings, with Pass@1 rising in four of them.

The plugin works with Claude Code, Codex, GitHub Copilot CLI and Pi. It does not modify model weights or agent code, and its learned data stays local in ~/.tokeneconomizer.
