openai/gpt-5.4-nano
GPT-5.4 nano is the most lightweight and cost-efficient variant of the GPT-5.4 family, optimized for speed-critical and high-volume tasks. It supports text and image inputs and is designed for low-latency...
At a glance
Based on 1,000 input and 500 output tokens using the latest published median speed data.
Visual comparison
Compare published endpoint pricing and estimated response time visually.
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 $0.0004125.
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. OpenAI is closest to the ideal combination of lowest cost and fastest response.
Server-rendered comparison
Prompt and completion prices are effective USD per token as published by OpenRouter. Missing speed data never removes an endpoint.

GPT-5.4 Nano deployment guide
GPT-5.4 Nano is indexed here as a text model by OpenAI, with 3 provider endpoints from Azure, OpenAI. The comparison preserves each exact OpenRouter routing tag so pricing and performance observations can be connected to the route an application would actually request.
The model publishes a 400K-token context window. It accepts file, image, text 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.
OpenAI currently has the lowest estimated cost for the standard 1,000-input/500-output-token sample at $0.0004125. Input-heavy and output-heavy applications can produce a different result, so review both per-million-token prices in the endpoint table.
OpenAI currently has the shortest estimated 500-token response at 6.91 seconds. OpenAI is the single endpoint closest to the current ideal cost/speed combination. Recent observations can change, so validate finalists with your own prompts.
