Model ● Covered in 9 stories + Follow
gpt-oss-120B is an open-weight reasoning language model with 120 billion parameters, released under the Apache 2.0 license. Recent coverage describes it being deployed and benchmarked in multiple contexts, including instruction-following evaluations (with more than 75% failure to follow reasoning-step instructions), IT automation diagnostics where it exhibited higher averaged failure-mode counts on failed traces, and agent memory studies where it showed improved task completion with curated retrieval guidelines at lower token overhead than full guideline injection. The model has also been referenced alongside fine-tuning and optimization workflows via Together AI for domain specialization and local efficiency comparisons.
