Microsoft has released GitHub Copilot Fusion, which can route coding tasks between Claude and GPT models. On Artificial Analysis's Coding Agent Index, its Max setting scores 60, versus 62 for Claude Code; the per-task cost is $5.59 versus $11.42. Fusion consumes 7.2M tokens per task, about half of Claude Code's usage.
Particle-1 is now live on OpenRouter, and Particle claims it uses 28–52% fewer output tokens than DeepSeek V4.1 Flash on four coding benchmarks. The model is post-trained on DeepSeek V4.1 Flash; Particle reports it uses about 45% fewer tokens on average with accuracy close to the base model, priced at $0.25 per million input tokens and $1 per million output tokens, with a 1.05M context window.
Entire, founded by the former GitHub CEO, has launched a new generation of Git hosting that reworks code hosting, review, CI, and Agent session memory around human-AI collaboration. It uses Trail to replace the diff-centric PR timeline; each push is scored by a review Agent in a cloud sandbox and tracks unresolved issues, calling Claude Code, Codex, and others under the hood, with sandboxes provided by Daytona and E2B. Its self-developed Git service offers its own open-source benchmark, claiming pushes are up to about 89 times faster than GitHub, and it has integrated Buildkite and Depot as CI.
