This is the batch-processing variant of gpt-oss-20b, OpenAI's open-weight mixture-of-experts model (21B total parameters, 3.6B active, Apache 2.0 license, 128K-token context, released August 5, 2025), offering the same configurable reasoning effort at a lower cost via OpenRouter's asynchronous batch endpoint. It suits high-volume, non-latency-sensitive workloads like bulk summarization or classification rather than interactive tool-calling use.
