Usage limits in full
- GitHub Copilot access (Enterprise Cloud licensed)
- Eligible sales-managed enterprises only; gradual rollout from October 28, 2026. Not available to self-serve customers, GitHub Free/Team organizations or self-service Enterprise Cloud trials. Enterprise owners must assign seats; a license does not automatically grant Copilot access. $0/seat/month only for users with an existing GitHub Enterprise Cloud license; Copilot Standalone costs $10/user/month without that license. No included AI credits: metered usage is billed from the first use at $0.01 per AI credit, with model/task-dependent consumption. Inline completions and next edit suggestions remain unlimited and do not consume credits. Same feature and model eligibility as Copilot Enterprise, subject to policies, enabled models and spending controls; the model list is a verified subset, not an exhaustive promise. Both access options may coexist, but the entire enterprise must use this billing model: cannot combine with Business or Enterprise seats. Transition is voluntary via the account team and takes effect on an agreed first day of a month. No annual price is published. Fable models require the documented data-retention safeguards; no automatic ZDR entitlement.
- Microsoft 365 Copilot Business
- Add-on only: requires an existing eligible Microsoft 365 Business subscription. $21/user/month with annual commitment ($252/user/year); month-to-month $25.2/user/month. $18.00/user/month first-year annual promotion runs 2026-07-01 through 2026-12-31, excludes trials and cannot be combined with other offers. Subscriptions auto-renew. Everyday chat and Copilot in apps are included; advanced experiences including Cowork, Code, Autopilot and Work IQ APIs are usage-billed beyond license fees. Teams license required for Teams features. No specific API model SKU or numerical usage quota is promised.
