Claude Opus 4.8
Claude Opus 4.8 is Anthropic's latest flagship LLM, released May 28, 2026 at unchanged pricing ($5/$25 per million tokens). It improves on Opus 4.7 across agentic coding, long-context reliability, and honesty — self-flagging code flaws roughly four times more often.
Launched 41 days after Opus 4.7, the release paired a model update with two new capabilities: Dynamic Workflows (run hundreds of parallel subagents from Claude Code for codebase-scale tasks, in research preview) and mid-conversation system messages (update agent instructions mid-run without breaking prompt-cache hits). Anthropic simultaneously announced a $65B funding round at a $965B valuation.
Think of it as the incremental tune-up before a next-generation engine: sharper, cheaper to run fast, and more honest when it stalls.
