Released 56 days after O3 Pro ยท All OpenAI releases
GPT-OSS 20B is an open-weight Mixture-of-Experts language model released by OpenAI in August 2025 under the Apache 2.0 license, alongside the larger 120B variant. It has 20.9B total parameters with 3.6B active per token across 24 layers, and can run on devices with around 16GB of memory. The model matches or exceeds OpenAI o3-mini on common benchmarks while staying highly efficient. It supports reasoning, tool use with function calling, and structured outputs, fitting cost-conscious agentic workflows and local inference. Its MoE design selects the top 4 of 32 experts per token, with a 128k context window, giving developers a compact open-weight option that keeps strong reasoning capability.
GPT OSS 20B runs on 8 different routes through the qynio gateway. Compare residency, zero retention, and training posture at a glance โ full data-handling detail per route below.

GPT OSS 20B runs on 4 independently monitored routes through the qynio gateway. A direct integration leaves you on one of them, the gateway serves whichever is healthy.
Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. 3 further routes for this model are not on the board yet and are not counted above. See uptime for every provider qynio monitors.
Each route hosting GPT OSS 20B has its own privacy posture, residency, and no-KYC terms. Postures are maintained by qynio with a last-verification timestamp.
