GPT-5.6 Luna is tracked as official api price verified. The verified first-party rate is $1.00 input and $6.00 output per 1M tokens. The OpenRouter channel remains separate so the two routes are not mistaken for one price.
What are the GPT-5.6 Luna input and output prices?
| Channel | Input / 1M | Cached input / 1M | Output / 1M | Verified | Source |
|---|---|---|---|---|---|
| Official direct | $1.00 | — | $6.00 | 2026-07-29 | Provider source ↗ |
| OpenRouter | $0.50 | $0.05 | $3.00 | 2026-07-30 | — |
Rates are normalized to USD per 1M tokens. This page does not replace a missing official price with an OpenRouter price.
What does GPT-5.6 Luna cost for a typical workload?
Using 1M input tokens and 250K output tokens, the estimated cost is $2.50 through the official route and $1.25 through OpenRouter. This example is calculated from the listed token rates and does not include taxes, tools, storage, retries, or optional OpenRouter credit purchase fees.
example = (1M × input rate) + (0.25M × output rate)
monthly estimate = example × your monthly runs

What are the context and lifecycle details?
Capacity is not a flat fee; billed tokens depend on what a request actually processes.
Standard text-token pricing. Tool calls are not included.
1 official and 1 OpenRouter observations are stored for this model.
Which OpenAI models are closest for comparison?
These same-provider models are selected by similar example workload cost where comparable prices exist. Use them as navigation shortcuts, not as a claim of equivalent capability.

How is this GPT-5.6 Luna price page maintained?
The official route uses the provider-owned source shown above. The OpenRouter route uses an explicit model-ID mapping and the exact OpenRouter record shown above. Source failures preserve the last verified record; a price-history event is added only when a verified input, cached-input, or output rate changes.

GPT-5.6 Luna pricing questions
How much does GPT-5.6 Luna cost per 1M tokens?
The verified first-party rate is $1.00 input and $6.00 output per 1M tokens. The mapped OpenRouter route is $0.50 input and $3.00 output per 1M tokens.
What is the GPT-5.6 Luna example workload cost?
For 1M input tokens and 250K output tokens, the estimated cost is $2.50 through the official channel and $1.25 through OpenRouter, before any optional OpenRouter credit purchase fee.
Does GPT-5.6 Luna have an OpenRouter route?
Yes. The route is stored separately under its OpenRouter model ID and has its own source and verification date.
What should I check before using GPT-5.6 Luna in production?
Confirm the linked provider terms, context and long-context rules, cache behavior, rate limits, latency, tool support, data policies, and actual token usage for your workload. This page is a pricing reference, not a capability or procurement recommendation.
