Microsoft's Experiences + Devices division is canceling Claude Code licenses and steering engineers to GitHub Copilot CLI before the fiscal year ends. The reason: costs spiraling to $2,000 per engineer per month, and a product conflict the company can no longer ignore.
MAI-Code-1-Flash, Microsoft's first purpose-built coding model for GitHub Copilot, started rolling out June 2 across Free, Pro, Pro+, Max, and Student plans. It's designed for fast, efficient responses at lower credit cost.
GitHub added a one-million-token context window and configurable reasoning levels to Copilot on June 4. Both are available in VS Code, the Copilot CLI, and the GitHub Copilot app, with more surfaces rolling out soon.
The GitHub Copilot App technical preview expanded to all Copilot Pro, Pro+, Business, and Enterprise customers on June 2. Headline additions include Canvases for bidirectional agent work, on-device voice, cloud sessions, and recurring automations that run without your machine.
GitHub Copilot's switch to usage-based billing hit on June 1. By June 2, developers were sharing real-world credit burn rates — and some are already planning exits.
Microsoft used Build 2026 to announce Project Polaris, a mixture-of-experts coding model built on Azure Maia accelerators that will replace GPT-4 Turbo as Copilot's default engine in August. Copilot Workspace also went generally available with fleet mode, autopilot, and new enterprise agent capabilities.
GitHub Copilot's switch from flat-rate subscriptions to GitHub AI Credits took effect June 1. The community announcement thread has nearly 1,000 downvotes, and some developers are projecting cost increases of 25x or more.
GitHub added a four-phase AI adoption classification to the Copilot usage metrics API, letting enterprise admins see how deeply their teams are using agent features. A separate CLI release the same day restored model selection for Free and Student plan users.
Anthropic's Claude Opus 4.8 went generally available in GitHub Copilot on May 28, available across VS Code, JetBrains, Xcode, and more. It's launching with a 15x premium request multiplier just before Copilot's token-based billing kicks in on June 1.
GitHub published two Copilot changelog entries on May 26: Copilot Memory gets better deletion guidance, a repository-level off switch, and CLI commands, while enterprise admins gain targeted model rules that let them pick which models each organization can access.
Copilot CLI 1.0.52 ships on May 23 with a context window tier fix that actually enforces the 200K vs 1M selection end-to-end, session resume in saved directories, and log file pruning. Version 1.0.53 the next day fixes multiline prompt display and a Bash hang.
GitHub quietly dropped every Gemini model from Copilot Chat on github.com on May 20, along with GPT-5.2 Codex and GPT-5.4 nano. OpenAI and Claude models remain available. GitHub says it's about reliability — the scope of what was cut says more than the explanation does.
Version 1.0.51 of the GitHub Copilot CLI adds session resumption with a --session-id flag, an experimental /security-review command for scanning code changes, and extended secret scanning into commit messages and PR descriptions.
GitHub published the full source code for its Eclipse IDE plugin on May 21, 2026. The repository at github.com/microsoft/copilot-for-eclipse contains roughly 15,000 lines of Java covering code completion, Next Edit Suggestions, chat, and agent mode.
Between May 18-20, GitHub added cheap cloud agent models, brought Gemini 3.5 Flash to IDEs, launched auto model selection in VS Code with a 10% discount, and then stripped all Gemini models from web chat.
GitHub made GPT-5.3-Codex the base model for all Copilot Business and Enterprise organizations on May 17, replacing GPT-4.1. It's GitHub's first long-term support model, guaranteed available through February 2027.
Version 1.0.49 of the GitHub Copilot CLI adds a /rubber-duck command that prompts the agent to independently critique its own current work, plus /chronicle for searching session history, persistent memory controls, and Alpine Linux support.
Two May 13 updates: JetBrains IDE users can now delegate tasks to a locally running Copilot CLI agent with worktree or workspace isolation, while a new REST API lets teams trigger cloud agent tasks programmatically.
GitHub's new native desktop app lets developers start agentic coding sessions directly from issues and pull requests, with each session running in an isolated branch and workspace. The app shipped v0.2.4 on May 15 with queued messages and collapsible tool-call panels.
GitHub announced a new Copilot Max plan at $100/month with $200 in total monthly value, introduced flex allotments to Pro and Pro+, and shipped code review improvements including severity labels and grouped comments — all taking effect on June 1 with the AI Credits billing switch.
Three Copilot CLI releases shipped May 6–11, adding a /autopilot toggle for autonomous mode, hooks that can handle requests without hitting the LLM, username display in the status line, and a sweep of path completion and slash command fixes.
GitHub is dropping the premium request unit system for all Copilot plans on June 1, 2026, switching to a token-based credit model. Opus is out of the Pro tier, sign-ups are paused, and the fallback experience is going away.
ServiceNow made Build Agent generally available at Knowledge 2026, extending it into the four major AI coding tools so developers can build ServiceNow apps without leaving their preferred IDE.
Starting June 1, 2026, GitHub Copilot replaces premium requests with GitHub AI Credits — token-based metered billing that ties cost directly to how much inference you consume.
