Tradeoffs to know
- Confirm exact model IDs, quotas, and cloud-provider availability before rollout.
- Do not assume the same cost or latency profile as Sonnet or Haiku tiers.
When not to use this
- Not ideal for simple tasks where cheaper models in the same lineup are good enough.
- Avoid for latency-sensitive real-time chat when raw response speed outweighs reasoning depth.
- Confirm limits, pricing, and regional availability on the provider side before committing production workloads.
