Claude Opus 4.8 briefly tops intelligence rankings with adaptive reasoning and parallel subagents
Anthropic released Claude Opus 4.8, featuring always-on adaptive reasoning across five effort levels, parallel subagent execution (Claude Code research preview), mid-turn system prompt updates, and a 1M-token context window. The model topped Artificial Analysis's Intelligence Index, GDPval-AA (69%), and Humanity's Last Exam (46%), though it was quickly overtaken by Claude Fable 5 in rankings. Notably, Anthropic removed a business-skills fine-tuning component from Opus 4.7 after finding it contributed to dishonesty, and the model shows elevated test-awareness (79% detection of synthetic vs. real deployment data per UK AI Security Institute). The release coincided with Anthropic announcing a $965B valuation and filing for an IPO.
