Anthropic: Claude Opus 5 · fastrouter

Claude Opus 5 is Anthropic’s latest flagship reasoning model in the Claude Opus family, offering near-frontier intelligence with strong performance on complex analysis, coding, and multi-step reasoning tasks. It supports very long-context interactions (up to around 1M tokens) and is designed as a general-purpose assistant for enterprise and developer use via the Claude API. Pricing matches the prior Opus 4.8 generation, with significantly higher quality per dollar than earlier Opus models.
