o3 task benchmarks
Confidence scores (0-100) and cross-provider rank for each task type. Rank 1 is best across all 72 models.
Not benchmarked. The third-party benchmark source used for confidence scores does not cover GPT models yet. Scores will appear here once independent benchmarks are published.
o3 cost by use case

Monthly cost projections
Projected monthly spend at different call volumes, using code generation as a representative workload (2,000 input / 4,000 output tokens per call).
| Calls / month | Without caching | With caching (75% read discount) |
|---|---|---|
| 1K | $36 | $33.9 |
| 10K | $360 | $339 |
| 100K | $3,600 | $3,390 |
| 500K | $18,000 | $16,950 |
| 1M | $36,000 | $33,900 |
Caching estimate assumes 70% of input tokens are cache reads. Your actual cache hit rate will depend on prompt structure and reuse.
