Compare published endpoint pricing and estimated response time visually.

Effective price by endpoint

USD per 1 million tokens for input and output. Lower is better.

OpenAI has the lowest estimated cost for 1,000 input and 500 output tokens at $0.06.

Estimated cost vs. response time

Based on 1,000 input and 500 output tokens. Cost is shown in USD per 1 million tokens. Lower and further left is better; the single best cost/speed trade-off appears at full opacity.

2 providers have complete pricing and speed data. Azure is closest to the ideal combination of lowest cost and fastest response.

GPT-5.4 Pro deployment guide

How to choose a GPT-5.4 Pro inference provider

GPT-5.4 Pro is indexed here as a text model by OpenAI, with 3 provider endpoints from OpenAI, Azure. The comparison preserves each exact OpenRouter routing tag so pricing and performance observations can be connected to the route an application would actually request.

Match the endpoint to the workload

The model publishes a 1.1M-token context window. It accepts text, image, file input and returns text output. 10 distinct supported parameters appear across the listed routes. Confirm limits on the specific endpoint rather than assuming every host exposes the same configuration.

Compare the real request economics

OpenAI currently has the lowest estimated cost for the standard 1,000-input/500-output-token sample at $0.06. Input-heavy and output-heavy applications can produce a different result, so review both per-million-token prices in the endpoint table.

Balance response start and generation speed

Azure currently has the shortest estimated 500-token response at 115.97 seconds. Azure is the single endpoint closest to the current ideal cost/speed combination. Recent observations can change, so validate finalists with your own prompts.
