OpenAI’s newest frontier model GPT-6 Astra is now on GitLab Duo Agent Platform, delivering faster runs and lower token usage. In GitLab’s internal evaluation, GPT-6 Astra finished a typical run 43.4% faster than GPT-5.6 Sol and used 42.7% fewer tokens per run, while completing every task in the benchmark . For your team, that means agentic tasks such as dependency updates, build fixes, and small multi-file changes come back faster, and stretch your token budget across more of your team’s backlog.
