MODEL PRICING
Compare AI API prices
Compare current text-model pricing from OpenAI and Anthropic to DeepSeek, Qwen, and Meta. Pricing is verified against provider sources.
Pricing other workloads? See embedding, text-to-speech, and image generation API pricing, or compare AI coding plans.
Explore the AI API Pricing Dataset for reusable pricing records, or review the Model Price Monitor for dated pricing updates. Not sure how many tokens a prompt uses? Paste it into the AI token estimator first.
