Claude Opus 4.8 is now available on ChatBotKit. It is Anthropic's best generally available model for coding, agentic tasks, and enterprise workflows, and it is ready to use today across bots, blueprints, skillsets, and direct API access.

Opus 4.8 builds on the foundation of Opus 4.7 with measurable gains in the areas that matter most for demanding production work. Complex multi-step coding, long-horizon agentic tasks, and professional workflows like document drafting, data analysis, and presentation building all benefit from the model's improved follow-through and sustained reasoning. For teams running sophisticated automations, it means agents that hold context longer and make better decisions across extended task chains.

The model ships with a 1 million-token context window and supports up to 128,000 output tokens, giving agents room to reason over large codebases, lengthy documents, and rich multimodal inputs in a single coherent session. Alongside chat and function calling, Opus 4.8 brings native reasoning and image understanding, making it a strong fit for Blueprint-driven automations and Skillset-powered agents that need to interpret visual context and coordinate tool use at scale.

Claude Opus 4.8 is available now in the ChatBotKit model picker. Select it from your dashboard or reference it directly via the API to start building with Anthropic's most capable model.
