Which should you choose?
Which is better: Qwen3 30B-A3B Instruct 2507, Llama 4 Scout 17B Instruct or GPT OSS 20B?
It is close. Our weighted score puts them within a point (Llama 4 Scout 17B Instruct 61/100, GPT OSS 20B 61/100, Qwen3 30B-A3B Instruct 2507 59/100), so choose by what matters most for your work: GPT OSS 20B for raw capability and Llama 4 Scout 17B Instruct for long inputs. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.
Which is cheaper, Qwen3 30B-A3B Instruct 2507, Llama 4 Scout 17B Instruct or GPT OSS 20B?
GPT OSS 20B is cheaper at $0.07 input / $0.25 output per million tokens (median across 37 API providers). Qwen3 30B-A3B Instruct 2507 costs $0.10 input / $0.30 output per million tokens (median across 12 API providers); Llama 4 Scout 17B Instruct costs $0.17 input / $0.59 output per million tokens (median across 13 API providers). At a typical mix of three input tokens to one output token, that is $0.115 per million tokens for GPT OSS 20B versus $0.15 for Qwen3 30B-A3B Instruct 2507 (1.3× as much) and $0.275 for Llama 4 Scout 17B Instruct (2.4× as much).
Which scores higher on benchmarks?
GPT OSS 20B scores higher on the Capabilities Index (ECI): GPT OSS 20B 137.8 (#122 of 165), Qwen3 30B-A3B Instruct 2507 137.3 (#124 of 165) and Llama 4 Scout 17B Instruct 129.6 (#138 of 165). The confidence ranges of the top two overlap (133.1–139.7 vs 131.7–139.4), so treat the gap as small. On individual benchmarks: GPQA Diamond — GPT OSS 20B 60.8%, Qwen3 30B-A3B Instruct 2507 55.6%, Llama 4 Scout 17B Instruct 51.8%; OTIS Mock AIME 2024–2025 — GPT OSS 20B 65.3%, Qwen3 30B-A3B Instruct 2507 62.2%, Llama 4 Scout 17B Instruct 7.8%.
Which is better for coding?
There are no published SWE-bench Verified results for Qwen3 30B-A3B Instruct 2507, Llama 4 Scout 17B Instruct and GPT OSS 20B yet, so there is no like-for-like coding score. On overall capability, GPT OSS 20B 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?
Llama 4 Scout 17B Instruct has the largest context window at 10,000,000 tokens, against 262,144 for Qwen3 30B-A3B Instruct 2507 and 131,072 for GPT OSS 20B. Maximum output per response: Qwen3 30B-A3B Instruct 2507 up to 16,384, Llama 4 Scout 17B Instruct up to 16,384, GPT OSS 20B up to 32,768 tokens.
Which can read images, PDFs, audio or video?
Qwen3 30B-A3B Instruct 2507 accepts text; Llama 4 Scout 17B Instruct accepts text and images; GPT OSS 20B accepts text. Llama 4 Scout 17B Instruct handles the widest range of inputs.
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 20B is the newest, released Aug 5, 2025. Qwen3 30B-A3B Instruct 2507 came out Jul 28, 2025; Llama 4 Scout 17B Instruct came out Apr 5, 2025. Knowledge cutoff: Llama 4 Scout 17B Instruct Aug 2024, GPT OSS 20B 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.
