Benchmarks

Scores on standardized evaluations and this model’s own outputs on shared benchmark prompts. Higher percentages are better — and each rank shows where this model lands among the models evaluated on that source.

Providers

This model is hosted by one provider. OpenRouter forwards every request to it directly — no routing decisions to make.

Pricing

The average price customers actually pay for this model, next to the prices providers post. Caching and discounts mean the price actually paid is often well below the listed one.

Performance

Throughput is how fast the model writes (tokens per second — higher is better). Latency is total round-trip time (lower is better). TTFT is time-to-first-token — how long before you see anything appear (lower is better).

Uptime

Uptime is the percentage of the past 3 days that at least one provider was responding to requests. Availability is the percentage of time that inference was successfully served. OpenRouter continuously monitors and uses the next-best provider when one returns an error.

Apps

Public apps that send the most traffic to this model. Good signal for what real production workloads look like — and a hint at which use cases this model is best suited for.

Activity

Token volume and request traffic to this model over time.

API

Drop-in code to call this model. OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. The only thing that changes between models is the model slug below.

GPT-5 Image has a 400,000 token context window. It supports up to 128,000 completion tokens.

No. GPT-5 Image does not accept tools, so function calling is unavailable. It also supports structured outputs via a JSON schema in response_format.

GPT-5 Image accepts images, text, and files such as PDFs as input and returns images and text. Up to 16 reference images can be attached to one request for image editing.

GPT-6 Luna Decisions, GPT-6.1 Sol Pro, GPT-6.1 Sol and 60 more are other text models from OpenAI.
