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.
GPT-OSS-20B is OpenAI's smaller open-weight model (around 20B parameters), designed to run on modest hardware for local or self-hosted reasoning and coding tasks. This is a free-tier variant of the model.
