Copilot Vendor page
GPT-6.1 Terra arrives in Copilot at $1 / $5 per 1M tokens
Changed (SGT) · GitHub · Entry updated
On 27 Oct 2026, GitHub: GitHub made GPT-6.1 Terra generally available in Copilot on Pro, Pro+, Max, Business and Enterprise, rolling out gradually; the changelog does not list Free or Student. It is billed from AI credits at provider list price: $1.00 input, $0.05 cached input, $1.25 cache write and $5.00 output per 1M tokens up to 272K input tokens, and $2.00, $0.10, $2.50 and $7.50 above 272K. That is half of GPT-6.1 Sol's $2.00 input and $10.00 output. AI-credit allowances did not change.
