Evaluation checklist
Compare output quality, supported inputs, context limits and total inference cost on the same workload. A family name or parameter count is not a quality benchmark.
Preview aliases change quickly, so verify the stable model ID, supported inputs, output modes and deprecation schedule.
Pricing and usage limits
Pricing, quotas and license conditions are not independently verified in this entry. Check the linked official source before choosing a production deployment. For a hosted deployment, check input and output charges, regional availability and rate limits for the exact model ID.
