Anthropic Launches Opus 4.8 with Effort Control Across Claude and Cowork

Anthropic has announced the launch of Opus 4.8, maintaining the same pricing structure as its predecessor version 4.7. The model became available immediately following the announcement. The release introduces effort control, a new capability being deployed across both Claude and Cowork platforms simultaneously. Displayed alongside the model selection interface, this feature allows users to fine-tune computational intensity—boosting it for complex problems or reducing it for straightforward tasks. The company invites developers and users to explore the new model and share their projects built with Opus 4.8.
