On 2026-10-14 GitHub updated HydraFusion, Copilot's multi-model orchestration feature, and added HydraFusion Max for harder tasks. The pool now includes Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna; effort is tuned per stage (medium for drafts, high for review), Cascade gains a judging step, and Critique now inspects the workspace with tools using parallel critics. Both remain in research preview across VS Code, the Copilot app and Copilot CLI.

GitHub’s 2026-10-01 Changelog launched Dynamic Workflows in public preview for Copilot CLI, the Copilot app, and the SDK: code-defined reusable orchestration (sequential/parallel steps, pause checkpoints, subagent cross-checks)—unlike Autopilot or /fleet, where Copilot invents the plan each run. CLI needs --experimental or /experimental on; available on all Copilot plans.

GitHub Changelog (@GHchangelog) launched public-preview local sandboxing in the Copilot app: per-project limits on filesystem, outbound/local network, and Git/GitHub CLI credentials to reduce blast radius from unintended agent commands. Off by default; enable “Sandbox new sessions” or /sandbox on for an active session. Not for cloud/remote-host sessions; if the OS cannot enforce policy, the sandboxed shell errors instead of running unsandboxed.

GitHub staffer Pierce Boggan (@pierceboggan) announced Copilot Auto model selection now offers three tiers—efficiency (cost-first), balance (cost/quality/latency), and intelligence (quality-first). Auto still picks a model per prompt; usage is billed on the selected model, and paid subscribers keep a 10% Auto usage discount. Rolling out in VS Code, Copilot CLI, and the GitHub Copilot app (changelog 2026-09-14).

Gemini 3.8 Flash is now in the GitHub Copilot model picker across Pro, Pro+, Max, Business, and Enterprise—on VS Code, Visual Studio, Copilot CLI, cloud agent, Copilot app, JetBrains, Xcode, and Eclipse. Unlike GPT-6 Astra, Flash is available on plain Pro; introductory usage-based provider pricing runs through 2026-12-31.

GitHub (@github) announced Copilot Day on September 10 with live demos of the Copilot app, CLI, and the HydraFusion multi-model orchestration research preview. Developers can set a reminder at gh.io/GitHubCopilotDay to follow the latest Copilot terminal and orchestration features.

GitHub Copilot App weekly recap (Aug 29–Sep 5): 1 release and 237 improvements. Highlights include /goal for persistent autopilot objectives in local sessions, MCP install via deep link with a prefilled review form, Power BI MCP in the catalog (hosted remote and local), and configurable reasoning effort for code-review agents. Notes: github.com/github/app/releases.

GitHub says OpenAI GPT-6 Astra is generally available in GitHub Copilot for long-horizon, autonomous coding and agentic work. Internal testing highlights plan-and-validate loops, batched diagnosis with verification, and self-confirmation before task completion—stronger long-horizon coding with fewer steps than prior OpenAI models. Available to Copilot Pro+, Max, Business, and Enterprise in VS Code, Visual Studio, Copilot CLI, coding agent, Copilot app, github.com, Mobile, JetBrains, Xcode, and Eclipse; billed at provider list pricing under usage-based billing, with admin model-policy controls.

GitHub announced Claude Fable 5.1, Anthropic’s latest Mythos-class model, is generally available in GitHub Copilot. Internal testing highlighted long-running coding, deep codebase research, and complex agentic workflows, and it is selectable in the Copilot app, CLI, and VS Code (@code).

GitHub said developers no longer need to hop between a separate AI chat and their development surface. Inside the GitHub Copilot app they can start projects, run multiple agent sessions, use Quick Chat, and preview the app in a browser canvas. The pitch is a single control plane from conversation to running UI, rather than copying context across tools.

GitHub said Gemini 3.7 Flash, Microsoft MAI-Code-1.1-Flash, and the Fireworks-hosted open-weight Kimi K3 model are generally available in the GitHub Copilot app, Copilot CLI, VS Code, and related surfaces. Developers can switch among Google's low-cost coding model, Microsoft's in-house code model, and an open-weight option without leaving the Copilot workflow. The same Copilot weekly thread also promoted a Customize tab that gathers MCP servers, plugins, skills, and canvases, plus Slack and Microsoft Teams integrations that let teams mention GitHub to plan changes, investigate problems, and hand off coding tasks from chat. For organizations standardizing on GitHub as the agent control plane, the release is less about a single SOTA model and more about routing: pick Gemini 3.7 Flash for cheap iteration, MAI-Code for Microsoft-stack tasks, or Kimi K3 when open weights and Fireworks hosting matter.
