About claude-sonnet-4.6
This introduction is transcreated for clarity and cross-checked against the cited model material.
Claude Sonnet 4.6 is Anthropic's balanced model for everyday coding, analysis, and content work, combining near-Opus capability with controlled cost and a 1M context window.
Core strengths
- A 1M context window and 128K output cover large repositories and evidence packs.
- Balances coding, computer use, document understanding, and tool use.
- Supports extended thinking plus image and PDF input.
Limitations
- Assistant-message prefilling is unsupported when migrating from 4.5.
- The default higher effort can add latency and should be set deliberately.
Selection and production evaluation
Start a claude-sonnet-4.6 evaluation by mapping its official positioning to real work: Large repositories, enterprise documents, agentic search, frontend design, and cost-sensitive multi-step knowledge work. The first pass should exercise both its main strength, "A 1M context window and 128K output cover large repositories and evidence packs.", and its known limitation, "Assistant-message prefilling is unsupported when migrating from 4.5.", 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 $3 / 1M tokens · Output $15 / 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.
