Specifications
Context windowHow much information the model can work with in one request, measured in tokens — pieces of words or other data. This includes your question, attachments, conversation and reply. Limits can vary by model variant and provider.

Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it.
—$0.10
Output priceWhat you pay for the text the model writes back. It is normally the dearer half: producing an answer costs more than reading one.
—$0.50
Cached input priceA reduced rate for text you send over and over. If every request starts with the same instructions or the same document, the provider keeps a copy ready and charges less to read it again.

Cheapest inputLowest input rate across every provider on OpenRouter, the lab included. The cheapest endpoint may run a quantised build or a shorter context — see "Available from" on the model page.

Cheapest outputLowest output rate across every provider on OpenRouter, the lab included. May come from a different provider than the cheapest input.

Benchmarks
BullshitBench v2Nonsense detection — Given a confidently-worded but nonsensical prompt, does the AI spot that it makes no sense and push back — instead of playing along and inventing an answer? The score is how often it clearly called out the nonsense. Higher is better.

Frequently asked questions

GPT-6 Luna leads Gemini 3.0 Pro on 3 of the 3 benchmarks they both report (BullshitBench v2, Next.js Evals, ARC-AGI-2). Only GPT-6 Luna has a verified first-party price for an available API: $0.10 per million input tokens and $0.50 per million output tokens. No currently available pay-as-you-go API rate is tracked for Gemini 3.0 Pro. Gemini 3.0 Pro shipped 308 days before GPT-6 Luna, so benchmark comparisons should account for the intervening progress.

Context windows are 1M (Gemini 3.0 Pro) vs 1.05M (GPT-6 Luna).

On BullshitBench v2, GPT-6 Luna leads at 59% vs Gemini 3.0 Pro at 48%. On Next.js Evals, GPT-6 Luna leads at 86% vs Gemini 3.0 Pro at 50%. On ARC-AGI-2, GPT-6 Luna leads at 59.3% vs Gemini 3.0 Pro at 31.1%.
