GitHub Copilot

GitHub has launched ReviewBench, an open benchmark for evaluating AI code review agents. According to GitHub, it uses representative pull requests, multi-source ground truth, calibrated evaluation, and production-aligned metrics. Dataset size, model scores, and licensing details were not included in the announcement summary.

GitHub has published a beginner's guide to canvases in the Copilot app, a feature that lets users describe an interface in natural language and have the agent build a live, interactive surface. The feature targets users who want custom workflow tools without writing code.

Microsoft launched an updated Copilot app that merges coding, productivity tasks, and custom agent creation into three tabs — Cowork, Code, and Autopilot. The company is shifting to usage-based pricing as it tries to close the gap with Anthropic's Claude in enterprise AI adoption.

GitHub has introduced local sandboxing in the GitHub Copilot app, a configurable feature that limits access to files, network resources, and credentials on a user's machine. The change targets risk reduction from unintended or unexpected command execution during agentic coding sessions.

GitHub used its own Copilot agent to help migrate the Copilot runtime to Rust, producing roughly 800,000 lines of production code. The company says the scale of the rewrite would not have been feasible without agentic coding assistance.

GitHub has released Project HydraFusion as a research preview in GitHub Copilot, an orchestration system that routes coding tasks across multiple models. GitHub claims its selective workflows matched or exceeded an Opus 5 baseline in offline evaluations while cutting estimated workflow cost.

GitHub has published a beginner-focused guide explaining how to run multiple Copilot agents concurrently within the GitHub Copilot app. The post walks new users through the workflow of parallel agent execution rather than announcing a new model or feature.

GitHub published details on how it approaches cost efficiency in Copilot, arguing that optimizing for shorter individual outputs can backfire by increasing retries and wasted work elsewhere in a coding task. The company frames efficiency as a full-task metric rather than a per-response one.

GitHub has launched a feature that lets teams mention @GitHub in Microsoft Teams channels, threads, or DMs to start a shared Copilot agent session visible to all participants. The update turns individual Copilot agent work into a collaborative, team-visible process directly inside Teams.

Slack has launched Slack Code, a feature that gives AI coding agents dedicated project channels where developers and non-technical staff can watch, review, and redirect their work in real time. Anthropic, GitHub, OpenAI, Cognition, and Vercel are building integrations, bringing Claude, Copilot, ChatGPT, and Devin into Slack's group chat environment.

GitHub Copilot for JetBrains now supports enterprise managed settings, letting administrators enforce consistent policies for plugin governance, MCP server access, OpenTelemetry, and permission modes across their organization.

GitHub published a blog post arguing that canvas-style interfaces—rather than chat logs—are better suited for tracking and steering agentic coding workflows in Copilot. The post frames canvases as a way to keep long-running agent work visible and controllable without re-running expensive steps.

GitHub published a guide showing how four Agent Apps can handle scoping, security review, rollout, and shipping of features directly inside GitHub, without switching tools. The post frames Agent Apps as a way to consolidate software delivery workflow steps into the GitHub platform.

Microsoft's MAI Code 1.1 Flash beats its predecessor and mini-models from Anthropic and OpenAI on SWE-bench Verified, but DeepSeek-V4-Flash-0731 outperforms it on Terminal Bench 2.1 (82.7% vs 62.9%) while costing roughly a third as much per token.

GitHub has released a Copilot SDK for Java, allowing enterprise developers to programmatically drive GitHub Copilot using idiomatic Java constructs like annotations and virtual threads. The release extends Copilot's SDK ecosystem beyond its existing language support.

GitHub has published a guide covering slash commands available in the GitHub Copilot app, designed to extend Copilot beyond simple chat into planning, team collaboration, task automation, and workflow customization. The guide targets developers looking to get more structured, repeatable value out of Copilot's interface.

GitHub has retired the Copilot Billing Preview app, removing it from availability entirely. Copilot spend tracking and management now happens directly within GitHub's standard billing settings.

GitHub deprecated Gemini 2.5 Pro and Gemini 3 Flash across all Copilot experiences effective July 31, 2026. The models are no longer available in Copilot Chat, inline edits, ask and agent modes, or code completions.

GitHub has added stacked sessions and pull requests to the GitHub Copilot app, allowing developers to break large coding tasks into a sequence of dependent Copilot sessions that each produce their own PR. GitHub demonstrated the feature by using it to modernize an old codebase.

Microsoft CEO Satya Nadella confirmed during a Wednesday earnings call that the company is merging Copilot chat, GitHub Copilot coding features, Cowork, and Autopilot agents into a single 'super app' launching this year. The move mirrors OpenAI's recent ChatGPT Work app, which combines ChatGPT and Codex.

GitHub has expanded its Copilot usage metrics API so that individual Copilot app activity is now attributed to users in enterprise-user and organization-user report rollups. The change gives admins more granular visibility into how Copilot apps are used across their organizations.

GitHub has deployed agentic workflows that automatically generate documentation pull requests from merged product changes. The system, built by GitHub's Aspire team, creates SME-reviewed documentation to reduce the lag between code releases and updated docs.

GitHub has published benchmark results for its Copilot agentic harness, evaluating performance across multiple tasks and over 20 different models. The company claims the framework achieves leading token efficiency while maintaining flexibility in model selection.

GitHub has updated Copilot CLI to support language server protocol (LSP) integration. The update replaces the tool's previous grep and decompile-based code analysis with structured language server support for improved code intelligence.

Microsoft has launched Scout, an AI assistant built on the OpenClaw framework that operates across Microsoft 365. The system requires a GitHub Copilot subscription and includes policy conformance checks with audit trails to address security concerns about autonomous AI agents.

Microsoft is ending GitHub Copilot's flat-rate subscription model in favor of token-based billing starting June 1. Some developers report monthly costs rising from approximately $29-50 to $750-3,000, while others claim the increases only affect inefficient "vibe-coders" who iterate excessively without clear direction.

GitHub is piloting an experimental AI agent designed to automate accessibility testing and remediation. The tool aims to help developers identify and fix accessibility issues in their code and user interfaces without requiring specialized expertise.

GitHub is restructuring its Copilot individual subscription tiers effective June 1, 2025. The company is introducing flexible model allotments to Pro and Pro+ plans and launching a new Max tier, responding to user feedback on plan structure.

IBM has launched Bob, its AI coding assistant, following internal testing with 80,000 employees. The company claims teams saw average productivity gains of 45% across complex workflows. Pricing ranges from $20 to $200 per month using a "Bobcoin" credit system.
