Claude Opus 4.8: Dynamic Workflows & 4x More Honest

Claude Opus 4.8 has been released, just 41 days after its previous version. This new model introduces Dynamic Workflows, allowing it to coordinate many subagents. It also tops GPT-5.5 on SWE-Bench Pro by over 10 points. What's interesting is that Opus 4.8 is four times more honest about its own uncertainty. This means it is less likely to let flaws in its code go unnoticed and more likely to admit when it doesn't know an answer. The model ships everywhere at the same pricing as Opus 4.7. Its new Dynamic Workflows feature allows Claude to plan large tasks, distribute work across subagents, and verify outputs. Early testers report Claude can now run up to 1,000 subagents in a single session. The bottom line is that this update brings significant advancements in how Claude operates and its reliability.
