GPT-4o

GPT-4o (azure) costs $2.50 per 1M input tokens and $10.00 per 1M output tokens, as last published by azure.

GPT-4o has a context window of 128,000 tokens (the maximum combined input and output it can handle in a single request).

GPT-4o sits in the large size tier. Size tiers run from micro (small enough to run on a device) through small, medium and large to extra large (frontier flagships), and are assigned from the model's family, naming and limits rather than its price.

GPT-4o can generate up to 16,384 tokens in a single response. Reasoning (thinking) tokens count toward this limit.

GPT-4o's training data runs through September 2023, so it may not know about later events. Coolhand records the cutoff at month precision, since providers often publish only the month.

GPT-4o accepts image and text as input and produces text as output, as recorded in the Coolhand catalog.

No — the weights of GPT-4o have not been released, so it is only available through hosted APIs.

No, GPT-4o is currently active with no announced deprecation date.

Call GET https://coolhandlabs.com/api/v2/inference_apis?q[source_api_eq]=azure&q[model_eq]=gpt-4o — free, no API key required, and scoped to just this model since source_api and model together are unique. See https://coolhandlabs.com/docs for the full REST API reference.

Coolhand also tracks GPT-4.1, GPT-4.1 Mini, GPT-4.1 Nano, GPT-4o Mini, GPT-5, and GPT-5.1 from azure. Some may already be deprecated, so check each model's status alongside its current pricing.
