Anthropic launches Claude Opus 4.8 and new effort selector

Anthropic has launched Claude Opus 4.8 globally at the same price as its predecessor.

The new model delivers faster responses, stronger coding and reasoning, and improved benchmark performance.

Claude.ai now includes effort controls, while Claude Code adds dynamic workflows for more flexible task handling.

Enterprise, Team, and Max plan users get preview access to additional features, and Anthropic says safety has improved with less misaligned behavior.
