gpt-oss-20b is a portable, open‑weight reasoning model offering o3‑mini‑level performance, agent-friendly tool use, and full chain-of-thought support under a permissive license. While it’s not as powerful as its 120 B counterpart, it’s uniquely suited for on-device, low-latency, and privacy-sensitive deployments. Developers should weigh its known compositional limitations, especially on knowledge-heavy tasks, and tailor safety precautions accordingly.
