What does OpenSiDot do?
Submitted on behalf of the OpenSiDot team. OpenSiDot is a free public reference for comparing AI models before choosing an API. It covers 349 models from 53 vendors and compares up to three side by side by input/output prices, context window, supported media, reasoning, tool calling and open weights. A separate LLM API pricing page estimates token-based costs. The data comes from an OpenRouter snapshot dated 2026-10-02, so it is not live pricing or a model quality benchmark. The comparison site is free to browse without an account; API usage with a vendor is billed separately. It compares model facts rather than running models. Team contact: support@opensidot.com.
