Which should you choose?
Which is better: GPT OSS 120B, Qwen3 30B-A3B Instruct 2507 or Qwen3 235B-A22B Instruct 2507?
It is close. Our weighted score puts them within a point (Qwen3 30B-A3B Instruct 2507 59/100, GPT OSS 120B 58/100, Qwen3 235B-A22B Instruct 2507 57/100), so choose by what matters most for your work: GPT OSS 120B for raw capability and Qwen3 30B-A3B Instruct 2507 on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.
Which is cheaper, GPT OSS 120B, Qwen3 30B-A3B Instruct 2507 or Qwen3 235B-A22B Instruct 2507?
Qwen3 30B-A3B Instruct 2507 is cheaper at $0.10 input / $0.30 output per million tokens (median across 12 API providers). GPT OSS 120B costs $0.15 input / $0.60 output per million tokens (median across 65 API providers); Qwen3 235B-A22B Instruct 2507 costs $0.199 input / $0.60 output per million tokens (median across 23 API providers). At a typical mix of three input tokens to one output token, that is $0.15 per million tokens for Qwen3 30B-A3B Instruct 2507 versus $0.263 for GPT OSS 120B (1.8× as much) and $0.299 for Qwen3 235B-A22B Instruct 2507 (2× as much).
Which scores higher on benchmarks?
GPT OSS 120B scores higher on the Capabilities Index (ECI): GPT OSS 120B 139.8 (#114 of 165), Qwen3 235B-A22B Instruct 2507 138.8 (#118 of 165) and Qwen3 30B-A3B Instruct 2507 137.3 (#124 of 165). The confidence ranges of the top two overlap (135.6–142.2 vs 135.5–140.9), so treat the gap as small.
Which is better for coding?
There are no published SWE-bench Verified results for GPT OSS 120B, Qwen3 30B-A3B Instruct 2507 and Qwen3 235B-A22B Instruct 2507 yet, so there is no like-for-like coding score. On overall capability, GPT OSS 120B 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?
Qwen3 30B-A3B Instruct 2507 and Qwen3 235B-A22B Instruct 2507 have the largest context windows (262,144 and 262,144 tokens), against 131,072 for GPT OSS 120B. Maximum output per response: GPT OSS 120B up to 32,768, Qwen3 30B-A3B Instruct 2507 up to 16,384, Qwen3 235B-A22B Instruct 2507 up to 16,384 tokens.
Which can read images, PDFs, audio or video?
GPT OSS 120B accepts text; Qwen3 30B-A3B Instruct 2507 accepts text; Qwen3 235B-A22B Instruct 2507 accepts text. They handle the same number of input types.
Are any of these open source?
Yes, all three publish their weights (Apache 2.0), so you can self-host them.
Which is newer?
GPT OSS 120B is the newest, released Aug 5, 2025. Qwen3 30B-A3B Instruct 2507 came out Jul 28, 2025; Qwen3 235B-A22B Instruct 2507 came out Jul 21, 2025. Knowledge cutoff: GPT OSS 120B Jun 2024.
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.
