This is the batch-processing variant of gpt-oss-120b, OpenAI's open-weight mixture-of-experts model (117B total parameters, 5.1B active, Apache 2.0 license, 128K-token context, released August 5, 2025), offering the same configurable reasoning depth and native tool-use design at a lower cost via OpenRouter's asynchronous batch endpoint. It fits high-volume, non-latency-sensitive reasoning and agentic workloads where throughput economics matter more than response time.

Claude Haiku 4.5 is Anthropic's fast, affordable small model in the Claude 4 generation, balancing strong instruction-following and coding ability with low latency. It is designed for high-throughput agentic and chat applications where speed and cost efficiency are priorities.
