GPT-4.1 pricing

Providers

GPT-4.1 starts at $2.00 per million input tokens and $8.00 per million output tokens via OpenAI.

Provider	Input $/M	Cached input $/M	Output $/M	Context in / out	TTFT p95 s	Output p5 c/s	Modalities in / out
OpenAI	$2.00	—	$8.00	1.0M/32.8K	10.00	—	/

Cached input is the discounted price for prompt tokens served from a provider cache. TTFT is time to first token. Output is characters per second; p5 is the sustained floor exceeded by 95% of observed requests.
