tokens
This model also charges $0.01 per search request
That is $10.00 per 1,000 requests, billed on top of the token prices above. On a typical 1,000-in / 500-out exchange the tokens cost $0.006, so the search fee is 1.7× the token cost. Per-token rankings elsewhere ignore this entirely.
Who serves it cheapest
2 hosts serve GPT-4.1. Same weights, same API - the price difference is pure margin and routing.
| Provider | Input / 1M | Output / 1M | Context | Throughput | Uptime 24h |
|---|---|---|---|---|---|
| AzureCheapest | $2.00 | $8.00 | 1.0M | - | 98.5% |
| OpenAI | $2.00 | $8.00 | 1.0M | - | 100.0% |
The spread between Azure and OpenAI is about the same for identical weights. Quantization and context limits differ, so check both columns before switching.
