All prices USD. Token prices are per 1M tokens. cached_input = cache read; cache_write (GPT-5.6+/GPT-6 only) = 1.25× uncached input. Long context = prompts >272K input tokens (2× input/cache, 1.5× output for the whole request).

# Service tiers

Tier	`service_tier`	Price rule	Notes
Standard	`default` / omitted	list price
Batch	Batch API (`/v1/batches`, `completion_window: 24h`)	50% of standard	separate, much higher queue limits; 24h turnaround
Flex	`flex`	Batch rates (50%)	beta, limited models; slower; may return 429 `resource_unavailable`; raise client timeout (15 min recommended)
Fast (ex-Priority)	`fast` or `priority`	2× standard for GPT-5.6 Sol / GPT-6 Astra (per-model table)	renamed 2026-07-30; up to 2.5× faster; downgraded requests return `service_tier: default` and standard rates; no fine-tuned models/embeddings; unavailable for GPT-6 Astra with EU data residency
Ultrafast	—	—	limited preview for GPT-5.6 Sol (announced 2026-08-13), up to 14× faster
Regional processing	`us.`/`eu.`/`ae.` … prefixed domains	+10% uplift	models released on/after 2026-03-05 that are data-residency eligible

Regional processing (data residency) endpoints are charged a 10% uplift for models released on or after March 5, 2026, that are eligible for data residency. See our Your data guide for supported regions and processing details. OpenAI models in Amazon Bedrock are billed through AWS. Bedrock pricing in commercial regions matches OpenAI direct pricing for equivalent services. Priority processing was renamed Fast mode on July 30, 2026. You can use either service_tier: "priority" or service_tier: "fast" in your API requests. Learn more about Fast mode. GPT-5.6 Sol’s promotional pricing is available at least through November 21, 2026.

GPT-Live 1 voice sessions are billed per second,
$10.00 / 1k calls + Search content tokens billed at model rates.
Tokens used for built-in tools are billed at the chosen model's per-token rates. GB refers to binary gigabytes (also known as gibibytes), where 1 GB is 2^30 bytes. Web search content tokens are tokens retrieved from the search index and fed to the model alongside your prompt to generate an answer. For gpt-4o-mini and gpt-4.1-mini with the non-preview web search tool, search content tokens are billed as a fixed block of 8,000 input tokens per call. File search tool call pricing applies to the Responses API only. Container pricing includes Hosted Shell and Code Interpreter. Eligible container sessions will be billed by the minute, with a 5-minute minimum per session. Responses API, Chat Completions API, Realtime API, Batch API, and Assistants API are not priced separately. Tokens are billed at the chosen model's input and output rates.
Billing for gpt-rosalind-research begins on October 5, 2026. Cache-write pricing does not apply to this model. Access is limited to approved internal research through the trusted-access program. All eligible organizations will continue to get access to the latest GPT-Rosalind models as they’re released.

# Caveats

Prices are documentation values as of 2026-09-18; the pricing page states promotional pricing for GPT-5.6 Sol through at least 2026-11-21.
Fine-tuning: platform is winding down (no new orgs since 2026-05-07; job creation ends 2027-01-06); inference on fine-tuned models continues until the base model is deprecated.
Realtime/Live sessions, image tokens and video seconds are billed on different units — check unit in every record.
