Scope, an MIT-licensed research preview, gives Copilot and Claude Code one task, scores runs on a criteria graph with an LLM Judge, and keeps the evidence.
Since April 24, 2026, GitHub may train AI models on Copilot Free, Pro, Pro+ and Max interaction data unless you opt out. Here is the switch and what it covers.
Microsoft says GitHub Copilot will, by the end of October, choose local or cloud models per task, and let developers pick a local model. On-device MAI Code 1.1 Flash figures are Microsoft's own tests.
GitHub Copilot can exclude files from some features, but its content exclusion setting does not cover editor Agent mode. Here is where the boundary ends and what to check.
GitHub's 30 September 2026 changelog puts the HydraFusion research preview in VS Code 1.140 and the Copilot app. It picks a Single, Cascade, or Critique workflow instead of acting as one model.
On 2 October 2026 GitHub deprecated Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code, and Claude Opus 4.7 across Copilot, pointing users to Gemini 3.8 Flash, Kimi K3, and Claude Opus 5.5.
GitHub's 2 October 2026 changelog says Copilot code review is requestable from REST and GraphQL, with an effort level on each call. Balanced, which took effect on 28 September, is the default.
GitHub Changelog (Oct 1, 2026): dynamic workflows in public preview for Copilot CLI, app, and SDK—code-defined multi-agent orchestration (sequential/parallel), handoffs, verification, checkpoints. Not computer use.
GitHub Changelog (Oct 1, 2026): Copilot computer use is in public preview for Copilot CLI and the Copilot app on macOS and Windows—local GUI click/type/scroll with approval; orgs can disable. Not cloud remote control.
JetBrains opened early access for Air in JetBrains IDEs—Marketplace plugin or native in 2026.3 EAP. Bring-your-own Codex, Copilot, Claude, Junie, and ACP; multi-agent sessions. Early access, not generally available.
GitHub’s Stephen Toub details rewriting the Copilot agent runtime from TypeScript/Node into 800k+ lines of production Rust, shipping incrementally with an embeddable C ABI. Latency figures are GitHub eng benchmarks without model or network time.
Anthropic’s Claude Opus 5.5 (2026-09-22) is the new default Opus in Claude Code and shipped same-day across GitHub Copilot surfaces. The cost story is cache-heavy agent work — not the list-price cut alone.
