A practical first workflow

  1. Define a representative coding / research / writing task and its acceptance criteria.
  2. Pin the exact model identifier and confirm hosted api availability for your environment.
  3. Run a small evaluation that records correctness, latency, input/output usage and review time.
  4. Compare the result with another suitable model before scaling usage.

Before you commit

  • Workflow fit: Evaluating demanding multi-step work within the Claude API.
  • Limits and trade-offs: The provider’s positioning is not an independent benchmark; tool access and controls must be configured.
  • Full cost: Include input/output usage, hosting where relevant, retries, tools and evaluation time.
  • Data and permissions: Read the current terms for the chosen account or deployment. Confirm who can access uploaded material and which actions require review.

Common questions
