Plain language
OpenAI's family of openly released language models.
As stated in the literature
OpenAI's open-weight model series including GPT-OSS-120B; used as a frontier baseline in several agent and reasoning benchmarks.
Also called: GPT-OSS-120B, gpt-oss
Why it matters: Open weights from a major lab let academics and small teams probe a frontier-style model in ways closed APIs don't allow.
For example, papers comparing reasoning approaches often run GPT-OSS-120B alongside Llama and Qwen models as an OpenAI-lineage open-weight reference.
Heard on the show
“… Now, the authors also report a separate result on GPT-OSS, the larger 120B model, where mean latency improves by up to seven-point-five-six times — but worth …”Episode 016 — Why Your Coding Agent Stalls While the GPU Runs Hot
