Claude Opus 4.8

Anthropic's latest flagship with 1M context, dynamic workflows, and 2.5x fast mode. Best for long-horizon agentic tasks.

What is Claude Opus 4.8?

Claude Opus 4.8 is a large language model created by Anthropic, available on Multos AI as part of our multi-model platform. Anthropic's latest flagship with 1M context, dynamic workflows, and 2.5x fast mode. Best for long-horizon agentic tasks. With a context window of 1M tokens, it can process substantial codebases and complex multi-file projects in a single conversation.

Choose Claude Opus 4.8 for the hardest problems: designing systems with many competing constraints, reviewing entire codebases for architectural issues, or tasks where getting it right the first time matters more than speed. The 1M context means you can load entire projects.

Limitations: Slowest and most expensive model available. For routine coding tasks, it's overkill. Reserve for high-stakes decisions where quality justifies the cost.
