GAyesterdayUnverifiedAdded Oct 14, 2026
Gemini 4 Argon, Google’s newest frontier model, is now generally available in GitHub Copilot. It is designed for complex coding, agentic, and reasoning tasks. In early testing, Gemini 4 Argon solved more tasks than previous Gemini models on every coding benchmark, with its largest gains in Copilot CLI.

More GitHub Copilot releases
Every GitHub Copilot releaseEnterprise managed settings enforcement updates
Enterprise administrators can now require supported GitHub Copilot clients to retrieve current server-managed settings at startup instead of relying on a cached policy. We are also adding minimum client version requirements to governance-focused managed settings keys over time, starting with the sandbox key.
Client telemetry user attribution and configurable capture
Enterprise administrators can now use telemetry in managed settings to attribute GitHub Copilot activity to a user without collecting their prompts, responses, or tool content. The telemetry.capture.identity setting adds three attributes to OpenTelemetry (OTel) data: user.name : The authenticated Copilot account name, currently the GitHub login.
New controls and chat improvements in Copilot for JetBrains
This update brings more control over default models and MCP server in GitHub Copilot for JetBrains. It also makes diagnostics easier to address, improves chat navigation and account controls, and strengthens reliability across agent sessions, customizations, and worktrees.

Copilot code review: New organization billing options and controls
This release adds new billing and license controls for Copilot code review admins: Billing: Organization owners can bill Copilot code reviews from members with a Copilot license to the organization’s cost center instead of using up those members’ Copilot quotas.
Claude Haiku 5.5 in GitHub Copilot
Claude Haiku 5.5, Anthropic’s newest lightweight model, is now generally available in GitHub Copilot. It is designed for fast, high-volume work like subagents, quick edits, and terminal tasks. In early testing, Haiku 5.5 matched Claude Sonnet 5 on many coding tasks while using significantly fewer tokens and steps.

GitHub in October 2026What's included:
- Three training methods: Supervised fine-tuning (SFT) , direct preference optimization (DPO) , and reinforcement learning with group relative policy optimization (GRPO) . Each method trains a low-rank adapter (LoRA) or the full model weights. Custom loss functions : Train with any objective you compute in PyTorch from the model's log-probabilities.
