Claude Opus 5.5 became selectable in GitHub Copilot on September 22, 2026.<\/strong> GitHub lists Copilot Pro+, Max, Business and Enterprise as eligible plans, across ten Copilot surfaces. The rollout is gradual, and organization administrators can control access. Under current billing, the model uses GitHub AI Credits at Copilot\u2019s published token rates; GitHub\u2019s legacy annual Pro and Pro+ plans are an exception and do not receive new models. GitHub\u2019s launch notice<\/a> and its current billing pages are the controlling sources for access and cost.<\/p>\n\n\n\n

This guide covers the Copilot integration: where the model appears, which plans can select it, how usage is charged, and what to check if it is missing. Anthropic\u2019s wider Claude Opus 5.5 launch<\/a> is a separate model-selection and API story; Copilot\u2019s AI-credit prices below are not Anthropic API prices.<\/p>\n\n\n\n

Which Copilot plans include Opus 5.5?<\/h2>\n\n\n\n

GitHub names four eligible plans: Pro+, Max, Business and Enterprise. Copilot Pro, Free and Student are not listed as selectable plans for this launch; Free and Student are documented as Auto-model-selection-only. Check the account\u2019s billing mode as well as its plan: existing annual Pro or Pro+ subscribers who stayed on legacy premium-request billing do not get access to new models and features.<\/p>\n\n\n\n

Individual-plan totals above include the base and flex credit amounts shown in GitHub\u2019s plan table<\/a>. Business and Enterprise credits are pooled at the billing entity, so the per-user figures are contributions rather than isolated personal wallets. GitHub says extra use is billed in AI Credits; administrators should review the organization budget and paid-usage settings before enabling a high-volume model.<\/p>\n\n\n\n

How much does it cost in Copilot?<\/h2>\n\n\n\n

GitHub converts metered model usage into AI Credits at the published rates. One credit is $0.01. The current Copilot table lists these Opus 5.5 rates per one million tokens:<\/p>\n\n\n\n

\n
Token category<\/th>Copilot list rate per 1M tokens<\/th><\/tr><\/thead>
Input<\/td>$4.00<\/td><\/tr>\n
Cached input<\/td>$0.20<\/td><\/tr>\n
Cache write<\/td>$5.00<\/td><\/tr>\n
Output<\/td>$20.00<\/td><\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n

For example, suppose one interaction is billed as 100,000 input tokens, 20,000 cached-input tokens, 10,000 cache-write tokens and 5,000 output tokens. At the rates above, that is $0.400 + $0.004 + $0.050 + $0.100 = $0.554, or 55.4 AI Credits<\/strong>, before any interface rounding. This is a worked calculation from the published rates, not a measured Copilot session. Real agent work spans multiple interactions, and its total depends on the tokens Copilot reports in each category.<\/p>\n\n\n\n

Anthropic models have a separate cache-write rate in GitHub\u2019s table. Do not price a cache write as either ordinary input or a cached read. The same model\u2019s direct Anthropic API has its own rate card and billing relationship; this article\u2019s arithmetic applies only to GitHub Copilot usage-based billing.<\/p>\n\n\n\n

New usage-based billing replaced the old premium-request system on June 1, 2026. It is token-based: the model and number of tokens determine the charge. The legacy request multipliers remain relevant only to certain existing annual Pro and Pro+ subscriptions. GitHub explicitly says legacy annual users do not receive new models, so a Pro+ label alone does not establish Opus 5.5 access. See GitHub\u2019s billing transition guide<\/a> and legacy-plan rules<\/a>.<\/p>\n\n\n\n
