Frontier performance at a fraction of the cost. In the @ArtificialAnlys Coding Agent Index, Copilot Fusion Max scored within two points of Claude Code with Opus 5.5 Max at about half the API cost per task. Get 30% off through Nov. 30. Try it now. ⬇️ docs.github.com/copilot/conc…
Chart titled "Coding Agent Index vs. Cost per Task" by Artificial Analysis. The chart displays Artificial Analysis Coding Agent Index vs. average pay-per-token API cost per task (USD). It compares various agents, including some from Claude Code, Codex, Antigravity CLI, DeepSeek Harness, Grok Build, Opencode, Muse Code, Kimi Code CLI, and GitHub Copilot. The x-axis represents higher cost per task (USD) to lower cost per task (USD), and the y-axis represents the coding agent index. The chart highlights a "Most Attractive Quadrant" in green and uses dots to differentiate agents. Copilot Fusion (max) sits within the most attractive quadrant.

Bar chart titled "Artificial Analysis Coding Agent Index". Incorporates 3 benchmarks: FrontierCode v1.1, Terminal-Bench 4.0, SWE-Atlas-QnA-AA. A higher scroe denotes higher average intelligence across becnhmarks. Copilot Fusion Max from GitHub Copilot has a score of 60. The chart also includes various coding agents from Claude Code, Devin Fusion CLI, Antigravity CLI, Codex, Grok Build, DeepSeek Harness, Muse Code, Opencode, Antigravity CLI, and Kimi Code CLI, with scores ranging from 62 to 41. Source and logo of Artificial Analysis are included at the bottom.

Your agent may have started the work, but you can finish the task in your IDE. Open a GitHub Copilot app session directly in @code. The task, plan, conversation, and code changes all come too (so you don't need to start over 😅). Here's every step ⬇️ github.blog/ai-and-ml/github…

💡 Bring all your related work together with projects in the GitHub Copilot app. Give Copilot a goal and it will coordinate the work. Your project can span one or more repos or focus on tasks that don't require one. Copilot can start sessions, set up recurring automations, or create artifacts; they'll show up in your project. 🗂️ Keep your sessions together to work toward one objective. Get started 👇 docs.github.com/copilot/how-…

Instead of picking the model for each and every task, let Copilot Fusion route and orchestrate which model to use. ✅ Copilot Fusion balances performance and cost efficiency, picking from three execution patterns for the job: Single, Cascade, or Critique. All you need to do is choose the effort level. Try it in the GitHub Copilot app, Copilot CLI, and @code, now 30% off through November 30.
Diagram titled "Three execution patterns in Copilot Fusion," comparing three workflows: Single, where a primary model uses tools to request an answer; Cascade, where a primary model makes a first pass before a judge model either accepts its result as the answer or escalates to a repair model for a fresh-start answer; and Critique, where a primary model drafts an answer and a read-only critic either approves it as-is or requests a revision by the primary model.
