Anthropic released Claude Opus 4.8 on May 28, 2026, as an incremental but material upgrade to its Opus line, targeted at coding, agentic workflows, and complex knowledge work, according to Anthropic’s announcement and product docs. The release introduces a fast mode that offers up to 2.5x higher output tokens per second at premium pricing and a lower cacheable prompt minimum of 1,024 tokens, per Anthropic’s model docs. Anthropic’s public materials and press coverage note availability across the Claude API, Amazon Bedrock, Google Vertex AI, Microsoft Foundry, GitHub Copilot, and GitLab integrations. The company also reports improved benchmark performance on agentic coding and long-horizon tasks; pricing details in Anthropic’s docs list $5 per million input tokens and $25 per million output tokens as a baseline.
