gpt-oss-120b is a large language model released by OpenAI, released under the Apache-2.0 license, with a claimed knowledge cutoff of 2025-08-05. Its weights, configuration, and tokenizer files have been cryptographically hashed and are queued for on-chain attestation by Weight Registry.
Description
Larger size in OpenAI's first-ever open-weight release, alongside gpt-oss-20b -- a genuine historical first for a lab that had otherwise kept every model closed/API-only since GPT-2.
