benchr's read
Worth it for
- Production default
- Cost-effective coding
- Bulk content tasks
- Daily-driver API workloads
Look elsewhere if
- You need frontier-grade reasoning
Prices, limits, and identifiers above are provider facts. This section is benchr's judgement about them.
What benchr has written about it
Pieces that name this model, newest first. The ones written about this model come before the ones that mention it in passing.
What is not on this page
Stated rather than filled in.
- No first-token or tokens-per-second figure is recorded. benchr has not measured it and the provider does not publish one.
- benchr has not run any capability on this model itself. Everything in the capability section is documentation, not a test result.
