Which is cheaper, Qwen3.8 27B or GPT-6.1 Sol?

Qwen3.8 27B is cheaper at $0.40 input / $2.55 output per million tokens (median across 49 API providers). 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 $0.938 per million tokens for Qwen3.8 27B versus $4.00 for GPT-6.1 Sol (4.3× as much).

Which scores higher on benchmarks?

GPT-6.1 Sol scores higher on the Capabilities Index (ECI): GPT-6.1 Sol 167.8 (#4 of 165) and Qwen3.8 27B 151.8 (#54 of 165). Their confidence ranges do not overlap (164.3–172.5 vs 149.9–153.6), so the gap is a real one.

Which is better for coding?

There are no published SWE-bench Verified results for Qwen3.8 27B and GPT-6.1 Sol 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. Both 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 262,144 for Qwen3.8 27B. Maximum output per response: Qwen3.8 27B up to 32,768, GPT-6.1 Sol up to 128,000 tokens.

Which can read images, PDFs, audio or video?

Qwen3.8 27B accepts text, images and video; GPT-6.1 Sol accepts text, images and PDFs. They handle the same number of input types.

Are any of these open source?

Qwen3.8 27B publishes its weights and can be self-hosted; GPT-6.1 Sol is proprietary.

Which is newer?

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 Nov 2, 2026.
