Anthropic

Everruns runs agents on Anthropic Claude models through the Claude Messages API, mapping its provider-neutral messages, tools, and reasoning onto the Anthropic wire format.

What you get

Section titled “What you get”
  • Claude Messages API streaming.
  • Tool use mapped to provider-neutral Everruns tools.
  • Extended thinking — adaptive thinking on recent Claude families and budget-based thinking on older ones, with the chain-of-thought signature preserved across multi-turn conversations.
  • Prompt caching via bounded cache_control breakpoints on stable, high-value sections of the request.

Models

Section titled “Models”

Anthropic’s /v1/models endpoint returns capability metadata, which Everruns merges with its built-in model profiles. Hardcoded profiles take precedence for cost data; discovered data fills gaps for newer models.

max_tokens is required on every Anthropic request, so Everruns always resolves a value from the model profile (falling back to a safe default) and will retry once with a lower limit if a stale profile causes the provider to reject it.
