Compare API pricing for GPT-5, Claude 4, Gemini 3, and more side by side. Enter your average token usage and daily request volume to instantly see all models ranked cheapest to most expensive. Optionally add a second scenario to rank models by combined monthly cost across two workloads.
At 1,000 requests/day with short messages, mini-class models cost 10–20× less than premium options. Switching from a premium to a budget model here saves over $1,000/month.

It depends on your token mix and volume. For short-context, high-volume workloads, GPT-5.4 mini and Claude Haiku 4.5 are typically the most cost-effective hosted options. For long-context tasks, compare carefully — output token pricing often dominates total cost.
Generating tokens requires significantly more compute than reading them. Models must run the full forward pass for every output token, whereas input tokens are processed in parallel. Output pricing is usually 3–6× higher per million tokens.
No. Anthropic and Google offer prompt caching that can reduce repeated input costs by 50–90%. If your application has a large fixed system prompt, enable caching and use the AI API Cost Calculator to estimate your effective rate.
Prices are refreshed from public sources on each production build. The displayed prices reflect the last build date. Major model price changes happen every few months — check the provider's pricing page for the latest rates.
Enable Compare a second scenario and enter token counts and daily volume for a second workload (e.g. a lightweight chatbot plus a heavy RAG pipeline). The table ranks models by combined monthly cost so you can pick one model that minimizes total spend across both use cases.
