GitHub Claude Opus 4.8 Is Now in GitHub Copilot, and Usage-Based Billing Starts Tomorrow
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.
Claude Opus 4.8 went generally available in GitHub Copilot on May 28. GitHub says early testing shows the model is a clear step forward on code understanding and generation, including “complex problem-solving and large-codebase navigation.”
The timing is notable. Usage-Based Billing launches June 1, which is tomorrow. Opus 4.8 is launching with a 15x premium request multiplier, which sets the cost baseline before per-token pricing takes effect.
Where it’s available
Opus 4.8 is available to Copilot Pro+, Business, and Enterprise users. You can select it from the model picker in:
- Visual Studio Code (chat, ask, edit, and agent modes)
- Visual Studio
- Copilot CLI
- GitHub Copilot cloud agent
- GitHub Copilot App
- github.com
- GitHub Mobile (iOS and Android)
- JetBrains
- Xcode
- Eclipse
GitHub notes the rollout is gradual, so it may not show up immediately in all accounts.
For Business and Enterprise plans, administrators need to enable the Claude Opus 4.8 policy in Copilot settings before users can access it.
What changes on June 1
Starting June 1, Copilot switches to Usage-Based Billing. Under the new system, AI interactions consume credits rather than counting against a monthly request cap. One AI credit equals $0.01, and credits are consumed based on token usage at each model’s API rate. Code completions don’t consume credits.
Base plan pricing doesn’t change: Pro stays at $10/month, Pro+ at $39, Business at $19/user, Enterprise at $39/user. The shift is in how premium model usage gets metered after the included allotment runs out.
The 15x multiplier on Opus 4.8 means it’s the most expensive model currently in Copilot, reflecting the same pricing tier as other Opus-class models. Cheaper models like Claude Sonnet and GPT-5 variants carry lower multipliers.
Developer reaction
The community response has been mixed. Some users have welcomed Opus 4.8’s availability as a meaningful capability upgrade for complex tasks. Others have been critical of the billing shift. The argument appearing most often in the GitHub community discussions: users on fixed-price plans will do less with AI to avoid surprise charges, making effective access worse even though the nominal plan price didn’t change.
Copilot Free users are unaffected by the multiplier system for now; they have separate limits that were updated separately.
Context
Anthropic launched Opus 4.8 a few days earlier with its Dynamic Workflows feature and a 69.2% score on SWE-Bench Pro. This Copilot integration makes it accessible to developers who use GitHub’s tooling rather than Anthropic’s API or Claude Code directly.
