Model pricing
GPT-4.1 pricing
GPT-4.1 by OpenAI costs $2 per 1M input tokens and $8 per 1M output tokens (cached input $1, batch input $1) as of 2026-10-31. A 1,000-input/500-output request costs $0.006. The lowest-cost alternative with at least this context window and the same recorded reasoning category is GPT 4.1 Nano (OpenAI) at $0.05/$0.2; capability equivalence is not guaranteed.
Notes
Legacy — 1M context, still strong on coding/instructions

Frequently asked questions
What does GPT-4.1 cost per million tokens?
Input costs $2 and output costs $8 per million tokens. The 1,000-input/500-output example costs $0.006, before discounts, taxes, hidden reasoning tokens or context-tier surcharges.
Does GPT-4.1 have cached or batch pricing?
Cached input: $1 per million tokens under the existing provider cache rules. Batch: $1 input and $4 output per million tokens. Eligibility and cache-write charges depend on the provider; these discounts are not automatically stacked.
What is a cheaper alternative to GPT-4.1?
GPT 4.1 Nano (OpenAI) costs $0.05 input and $0.2 output per million tokens. This comparison matches context capacity and reasoning category, not benchmark quality. Test your workload before replacing a model.
How often are these prices verified?
The live pricing table synchronizes stored model records daily; public file snapshots update when the site is rebuilt. Synchronization is not independent provider verification. Snapshot updated 2026-10-31. No model-specific verification date is recorded; the snapshot date must not be interpreted as an official provider verification.
