Pricing
FreemiumGitHub Copilot Free costs $0/user/month and includes 2,000 completions per month, access to models like Haiku 4.5 and GPT-5 mini, Copilot CLI, and community support. Pro costs $10/user/month and adds cloud agent and code review access, unlimited code completion and next-edit suggestions, access to third-party agents like Claude Code and Codex, model selection, and $15 in monthly total credits. Pro+ costs $39/user/month and adds premium models including Opus, audit logs, 4x+ more included usage than Pro, and $70 in monthly credits. Max costs $100/user/month for sustained high-volume agent workflows, with priority access to new models, 2.9x+ more usage than Pro+, and $200 in monthly credits. For businesses, the Business plan costs $19/user/month with unlimited code completion, cloud agent and code review access, a broad model catalog, access control, budget governance, and IP indemnity. Enterprise costs $39/user/month with everything in Business plus priority access to new models and 2x the included usage. GitHub AI Credits (1 credit = $0.01) meter usage for chat, agents, CLI, Spaces, and Spark beyond the included monthly allowance.
PaidThe OpenAI API uses pay-as-you-go, per-token pricing that varies by model. GPT-5.6 Sol, built for complex reasoning and coding, costs $5.00 per 1M input tokens and $30.00 per 1M output tokens with a 1.05M context length. GPT-5.6 Terra, balancing intelligence and cost, costs $2.00 per 1M input tokens and $12.00 per 1M output tokens. GPT-5.6 Luna, designed for cost-sensitive, high-volume workloads, costs $0.20 per 1M input tokens and $1.20 per 1M output tokens. All three share a 1.05M context length and 128K max output tokens. Additional costs apply for fine-tuning, evals, and specialized tools like web search or file search depending on usage. New accounts must add billing details before making live API calls, and there is no free-tier token quota; enterprise organizations can contact sales for custom pricing, dedicated support, and advanced data residency and retention controls.
