OpenAI’s GPT-6 Sol and GPT-6 Luna now available
Source: https://github.blog/changelog/2026-09-22-openais-gpt-6-sol-and-gpt-6-luna-now-available/ OpenAI’s GPT-6 family is expanding in GitHub Copilot with two additional models: GPT-6 Sol, and GPT-6 Luna. Joining the previously released GPT-6 Astra, these new options let you select the model that best fits your task, whether that’s everyday agentic coding or fast, cost-efficient assistance.
- **GPT-6 Sol:**A balanced model for interactive and agentic coding. A strong all-round choice for development tasks that benefit from careful, multistep validation.
- **GPT-6 Luna:**A lightweight, cost-efficient model for smaller, faster tasks and the lowest-cost option in the GPT-6 family.
These models are billed under usage-based billing. Seepricing for GitHub Copilot models and requestsfor details.
