What is Claude Sonnet 3.5 v2?

Claude Sonnet 3.5 v2: overview

Balanced Claude model for coding, analysis, agent workflows, and cost control

What the source record says

It identifies the model family as claude-sonnet and describes open weights as not indicated as available. These fields are useful for narrowing a shortlist, but the linked primary source remains the reference for any current release or policy change.

Interface and modality fit

Claude Sonnet 3.5 v2 accepts text, image, pdf and returns text according to the registry. That makes the model a potential fit only where those interface assumptions match the product workflow. A team should test its own file types, tool schema, safety settings, and deployment constraints rather than assuming that a listed modality works identically in every provider surface.

Limits and operating assumptions

The listed context window is 200,000 tokens, with a listed maximum output of 8,192 tokens. The source declares tool calling, file attachments, temperature control. Those flags describe an interface surface; they are not evidence of response quality, speed, tool reliability, or availability.

Benchmark results

The linked publisher results describe specific tests and settings. Use them alongside a trial of the prompts, tools and files your application needs.

Test the interface on real work

Use inputs that resemble deployment traffic, including difficult and out-of-domain cases. Compare output correctness, the response format, latency and memory requirements with a simple baseline under the same conditions.
