## About claude-opus-4.6

Claude Opus 4.6 is Anthropic's high-end reasoning and multimodal model for complex scientific, engineering, legal, and accuracy-first professional work.

### Best for

Multi-step cross-domain reasoning, complex system design, professional analysis, large repositories, and chart or document understanding.

### Core strengths

- Prioritizes depth, precision, and professional knowledge in complex reasoning.
- Supports text and image input, extended thinking, and tools.
- Long context fits entire repositories or large evidence packs.

### Limitations

- Cost and latency exceed Sonnet, reducing value for simple tasks.
- Live information, code execution, and computer use depend on tool integrations.

### Selection and production evaluation

Start a claude-opus-4.6 evaluation by mapping its official positioning to real work: Multi-step cross-domain reasoning, complex system design, professional analysis, large repositories, and chart or document understanding. The first pass should exercise both its main strength, "Prioritizes depth, precision, and professional knowledge in complex reasoning.", and its known limitation, "Cost and latency exceed Sonnet, reducing value for simple tasks.", instead of relying on a single subjective general-chat comparison.

For access, MoleAPI currently lists openai protocols and the Standard billing groups for this Anthropic model; the default price summary is Input $5 / 1M tokens · Output $25 / 1M tokens. Pricing, protocols, and groups come from the live catalog, so production planning should still price representative requests using real context length, output size, and cache-hit assumptions.

No independent ranking is shown unless it matches this exact model ID and reasoning profile, so nearby variants are not used as a proxy. Before launch, pin the model ID, prompt, and sample set, then compare task accuracy, structured-output validity, tool-call success, and timeout rates under the same conditions.

The model material on this page was last checked on 2026-07-24. When upstream model cards, context limits, or tool support change, update the cited bilingual facts before changing the recommendation; live MoleAPI price changes remain separate and update from the catalog automatically.
