Auto Router is OpenRouter's task-aware meta-router: it classifies each prompt into one of roughly 30 task types and routes it to the model the community spends most on for that task over a trailing 7-day window, filtered by a cost_tier dial (low by default) and kept sticky across a conversation's turns. Routing is free and each response is priced at the underlying routed model's rate, making it a good fit for mixed workloads where the best model varies from request to request.
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.
