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.

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.
35%59%
DeepSWE 1.1Agentic coding — Artificial Analysis' independent test of deep, agentic software-engineering work — the AI has to plan and carry out substantial coding tasks end to end. (Version 1.1 of the test.) Higher is better.
65.3%66.6%
Terminal-Bench 4.0Agentic terminal coding — Can the AI work in a command-line terminal — running commands and finishing technical setup tasks the way a developer would? Version 4.0 recalibrated how much time, CPU and memory each task gets, removed eight tasks and fixed nineteen, so fewer runs fail for reasons that have nothing to do with the model. Scores are not comparable with earlier versions. Higher is better.

ARC-AGI-2Abstract reasoning — Puzzle-style tests of abstract reasoning and pattern-finding — the kind of thing people find easy but AIs often struggle with. Higher is better.

threejsevalCommunity preference (Three.js) — Every model gets the same prompt — "the Eiffel Tower", "a glass fishbowl", "a robot arm picking toys into a box" — and builds a 3D scene in Three.js. Real people then see two scenes side by side, names hidden, and vote for the one they prefer. The votes become a chess-style Elo rating on threejseval.com, averaged across all the prompts. It measures whether the scene looks and moves right to a human eye, not whether the code passes a test. Higher is better.

Frequently asked questions

GPT-6 Luna leads Gemini 3.7 Flash on 3 of the 5 benchmarks they both report. 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 3.7 Flash. Gemini 3.7 Flash shipped 40 days before GPT-6 Luna, so benchmark comparisons should account for the intervening progress.

Context windows are 1M (Gemini 3.7 Flash) vs 1.05M (GPT-6 Luna).

On BullshitBench v2, GPT-6 Luna leads at 59% vs Gemini 3.7 Flash at 35%. On DeepSWE 1.1, GPT-6 Luna leads at 66.6% vs Gemini 3.7 Flash at 65.3%. On Terminal-Bench 4.0, GPT-6 Luna leads at 16.36% vs Gemini 3.7 Flash at 11.21%. On ARC-AGI-2, Gemini 3.7 Flash leads at 84.6% vs GPT-6 Luna at 59.3%. On threejseval, Gemini 3.7 Flash leads at 1468 vs GPT-6 Luna at 1365.
