Summary
GitHub launched user-based model policy targeting for Copilot in public preview on July 31, 2026, letting AI administrators set a baseline set of models for the whole enterprise and grant additional models to specific enterprise teams, moving model access control below the organization level.
What changed
Enterprise customers with Copilot Business or Copilot Enterprise can now set an enterprise-wide baseline of allowed models and grant extra models to specific enterprise teams, giving finer, user-based model access control instead of only organization-level policy.
Why it matters
As Copilot spans many frontier and cost-tiered models, role-based model governance lets platform teams give frontier teams early access while holding a conservative default for everyone else, matching model access to job function and cost policy.
Evidence excerpt
AI administrators can set a baseline of models for the entire enterprise and then grant additional models to specific enterprise teams. Historically, model access has been managed at the organization level, but enterprise teams give you finer grained, user-based control.
