Data last updated: 2026-10-16. Verify current model details with each provider.
What the listed data says
Qwen3 32B: 128K tokens; GPT-OSS 20B: 128K tokens. The listed context-window values are equal. Qwen3 32B is listed for coding, reasoning, agentic workflows, long-context tasks; GPT-OSS 20B is listed for no specific capability flags. Shared catalog benchmark entries: MMLU: Qwen3 32B 92.0%; GPT-OSS 20B 78.3%; HumanEval: Qwen3 32B 92.7%; GPT-OSS 20B 76.1%. These records are reference data, not a controlled head-to-head test; verify current pricing and specifications with each provider.
Catalog source links
Use these model and provider links to verify current specifications, pricing, and availability.
The first listed parameter quantities are 32B and 20B; the larger quantity is 1.6× the smaller. Total and active MoE parameters are not directly equivalent.
A release-date gap cannot be calculated from the catalog values (Qwen3 32B: April 2025; GPT-OSS 20B: 2025).
Cost example: 1M input and 1M output tokens
A cost example for 1M input plus 1M output tokens cannot be calculated reliably because separate numeric input and output rates are not listed for both models.

Qwen3 32B: 128K tokens; GPT-OSS 20B: 128K tokens. The listed context-window values are equal. Qwen3 32B is listed for coding, reasoning, agentic workflows, long-context tasks; GPT-OSS 20B is listed for no specific capability flags. Shared catalog benchmark entries: MMLU: Qwen3 32B 92.0%; GPT-OSS 20B 78.3%; HumanEval: Qwen3 32B 92.7%; GPT-OSS 20B 76.1%. These records are reference data, not a controlled head-to-head test; verify current pricing and specifications with each provider.
What benchmark values are listed for Qwen3 32B and GPT-OSS 20B?
MMLU: Qwen3 32B 92.0%; GPT-OSS 20B 78.3%; HumanEval: Qwen3 32B 92.7%; GPT-OSS 20B 76.1%. The catalog values may use different versions and evaluation setups, so they are reference points rather than a controlled head-to-head result.
Which model has the larger listed context window?
Qwen3 32B: 128K tokens; GPT-OSS 20B: 128K tokens. The listed context-window values are equal.
What are the listed costs per million tokens for Qwen3 32B and GPT-OSS 20B?
Qwen3 32B: input $0.3, output $0.7 per 1M tokens (Open source — free. Third-party API ~$0.14-0.30/MTok). GPT-OSS 20B: Separate numeric input/output rates not listed (MIT — free). Where separate numeric input and output rates are available, the worked example uses 1M input plus 1M output tokens. Confirm current terms with each provider.
How far apart are the listed release dates for Qwen3 32B and GPT-OSS 20B?
The catalog lists Qwen3 32B as April 2025 and GPT-OSS 20B as 2025; a release-date gap cannot be calculated from both records.
When was the comparison data last updated?
