DeepSeek API

Low-cost usage-based API for DeepSeek’s reasoning and chat models. Price it from the console, not from old tweets.

External model signals

DeepSeek API is scored here as a product. Two public boards rank the models it serves. Token usage informs momentum. Blind votes inform capability. Their numbers stay on their sites.

OpenRouter rankings. OpenRouter ranks models by tokens processed through the OpenRouter API. OpenRouter states that a higher token total shows how much a model is used, not which model is best for a task. That usage informs momentum.
Arena (LMArena leaderboard). Arena, also called LMArena, ranks models by blind human votes. People compare anonymous answers, and only those anonymous votes count toward the public board. Arena fits the votes with a Bradley-Terry model. Those votes inform capability. Method: Arena FAQ.
