Which should you choose?
Which is better: Grok 4.7 or Gemini 3.6 Flash?
Gemini 3.6 Flash is the better all-round choice, scoring 71/100 against Grok 4.7 (61). It leads on capability, price, inputs & features and context window. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%. Capability uses the average of shared benchmarks (GPQA Diamond, FrontierMath Tiers 1–3, OTIS Mock AIME 2024–2025 and SimpleQA Verified), because Grok 4.7 has no Capabilities Index score yet.
Which is cheaper, Grok 4.7 or Gemini 3.6 Flash?
Gemini 3.6 Flash is cheaper at $0.75 input / $3.75 output per million tokens (official Google API price). Grok 4.7 costs $2.00 input / $6.00 output per million tokens (official xAI API price). At a typical mix of three input tokens to one output token, that is $1.50 per million tokens for Gemini 3.6 Flash versus $3.00 for Grok 4.7 (2× as much).
Which scores higher on benchmarks?
Not every model here has a Capabilities Index score, so we compare the average of shared benchmarks (GPQA Diamond, FrontierMath Tiers 1–3, OTIS Mock AIME 2024–2025 and SimpleQA Verified): Gemini 3.6 Flash 78.4% and Grok 4.7 74.9%. On individual benchmarks: GPQA Diamond — Gemini 3.6 Flash 94.1%, Grok 4.7 92.7%; FrontierMath Tiers 1–3 — Gemini 3.6 Flash 59.0%, Grok 4.7 53.0%; OTIS Mock AIME 2024–2025 — Grok 4.7 98.1%, Gemini 3.6 Flash 94.2%; SimpleQA Verified — Gemini 3.6 Flash 66.2%, Grok 4.7 56.0%.
Which is better for coding?
There are no published SWE-bench Verified results for Grok 4.7 and Gemini 3.6 Flash yet, so there is no like-for-like coding score. On overall capability, Gemini 3.6 Flash leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.
Which has the bigger context window?
Gemini 3.6 Flash has the largest context window at 1,048,576 tokens, against 500,000 for Grok 4.7. Maximum output per response: Grok 4.7 up to 500,000, Gemini 3.6 Flash up to 65,536 tokens.

No. Grok 4.7 and Gemini 3.6 Flash are proprietary and only available through APIs and apps.
Which is newer?
Grok 4.7 is the newest, released Sep 21, 2026. Gemini 3.6 Flash came out Jul 21, 2026. Knowledge cutoff: Grok 4.7 May 2026, Gemini 3.6 Flash Mar 2026.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
