## AI overview

GitLab Duo Agent Platform adds GPT-6 Astra. GitLab reports faster typical and slow-tail runs plus lower token use than GPT-5.6 Sol, while noting Sol had a higher benchmark task-resolution rate.

## Source excerpt

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. Faster agentic work, even on your slowest runs Wait time factors into how your team uses an agent. A run that comes back in a few minutes is one you stay engaged with. A longer run is one you let work in the background while you move to another task. When it finishes, you switch context from the work you're in, reread what you asked the agent for, and review a diff you last thought about 30 minutes ago. The longer runs that result in context switching are the ones GPT-6 Astra shortened most in GitLab's internal testing. At the 95th percentile, the slower tail of its runs, GPT-6 Astra finished 49.2% faster than GPT-5.6 Sol, and 43.4% faster on a typical run. Astra's slowest runs finish in roughly the time Sol needed for an average one. With GPT-6 Astra, your team waits less on high volume, routine work. Every task finished, at a lower token usage per run In GitLab's internal testing, GPT-6 Astra completed 100% of benchmark tasks. No run stalled, timed out, or came back empty, so your team isn't left waiting on runs that finish with nothing to review. Astra resolved 63.3% of those tasks, returning a change that passed the benchmark's tests, compared to a 76.7% resolution rate for GPT-5.6 Sol. Misses return as patches to correct rather than runs that produced nothing. Astra reached its completion rate using 42.7% fewer tokens per run than Sol, measured across the same set of tasks. That savings compounds across a backlog, so your token budget covers more of the work your team d
