Mocha has partnered with Anthropic to evaluate the Opus 4.6 pre-release, now available to Mocha users in MAX mode. This new model exceeds its predecessor, Opus 4.5, with 25-30% longer performance before user intervention and a 10-15% increase in tool usage. Opus 4.6 employs an effective "explore, plan, execute" strategy, delivering polished UIs and thorough self-verification of outputs. This showcases a trend toward more autonomous AI models in 2026 and beyond.
