Claude Opus 4.6
This lands squarely in Factory's core zone.
Opus 4.6 is explicitly positioned around agentic coding, tool use, long-running tasks, larger codebases, code review, and debugging. Those are not peripheral features for Factory; they are the engine underneath ticket execution, PR review, and autonomous software work.
Factory still adds orchestration and enterprise workflow wrapping, but when Anthropic's flagship model gets materially better at the exact coding-agent job, Factory's core experience gets easier for Anthropic to productize directly.
