GPT-OSS-20B High provides enhanced reasoning capabilities with high-effort thinking for complex problems. This variant offers deeper analysis and more thorough responses compared to the base model, making it ideal for challenging tasks that require extended reasoning. Achieves near-parity with OpenAI o4-mini on core reasoning benchmarks while running efficiently on a single 80 GB GPU, or on edge devices with just 16 GB of memory. Note: While referred to as '20b' for simplicity, it technically has 20.9B parameters.
