Which should you choose?
Which is better: Grok 4.7, GPT-6.1 Sol or Qwen3.8 Max?
GPT-6.1 Sol is the better all-round choice, scoring 69/100 against Qwen3.8 Max (65) and Grok 4.7 (61). It leads on capability. Qwen3.8 Max wins on inputs & features. 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 and GPT-6.1 Sol has no Capabilities Index score yet.
Which is cheaper, Grok 4.7, GPT-6.1 Sol or Qwen3.8 Max?
Grok 4.7 is cheaper at $2.00 input / $6.00 output per million tokens (official xAI API price). Qwen3.8 Max costs $2.00 input / $6.00 output per million tokens (official Alibaba API price); GPT-6.1 Sol costs $2.00 input / $10.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $3.00 per million tokens for Grok 4.7 versus $3.00 for Qwen3.8 Max (1× as much) and $4.00 for GPT-6.1 Sol (1.3× 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): GPT-6.1 Sol 90.7%, Qwen3.8 Max 78.2% and Grok 4.7 74.9%. On individual benchmarks: GPQA Diamond — GPT-6.1 Sol 95.4%, Grok 4.7 92.7%, Qwen3.8 Max 92.7%; FrontierMath Tiers 1–3 — GPT-6.1 Sol 93.7%, Qwen3.8 Max 74.7%, Grok 4.7 53.0%; OTIS Mock AIME 2024–2025 — GPT-6.1 Sol 100%, Qwen3.8 Max 99.4%, Grok 4.7 98.1%; SimpleQA Verified — GPT-6.1 Sol 73.9%, Grok 4.7 56.0%, Qwen3.8 Max 45.8%.
Which is better for coding?
There are no published SWE-bench Verified results for Grok 4.7, GPT-6.1 Sol and Qwen3.8 Max yet, so there is no like-for-like coding score. On overall capability, GPT-6.1 Sol leads, which tends to carry over to coding, but test on your own codebase. All three support tool calling for agent workflows.
Which has the bigger context window?
GPT-6.1 Sol has the largest context window at 1,050,000 tokens, against 1,000,000 for Qwen3.8 Max and 500,000 for Grok 4.7. Maximum output per response: Grok 4.7 up to 500,000, GPT-6.1 Sol up to 128,000, Qwen3.8 Max up to 131,072 tokens.
Which can read images, PDFs, audio or video?
Grok 4.7 accepts text, images and PDFs; GPT-6.1 Sol accepts text, images and PDFs; Qwen3.8 Max accepts text, images, PDFs and video. Qwen3.8 Max handles the widest range of inputs.
Are any of these open source?
No. Grok 4.7, GPT-6.1 Sol and Qwen3.8 Max are proprietary and only available through APIs and apps.
Which is newer?
GPT-6.1 Sol is the newest, released Sep 29, 2026. Grok 4.7 came out Sep 21, 2026; Qwen3.8 Max came out Aug 3, 2026. Knowledge cutoff: Grok 4.7 May 2026, GPT-6.1 Sol Apr 30, 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.
