AI models charge per token - the basic unit of text. A token is roughly 4 characters or 0.75 words. Pricing is typically listed per million tokens for both input (your prompt) and output (the model response).
Several models are completely free including some from Google, Meta, and others. For paid models, pricing starts as low as $0.01 per million tokens. Check our cheapest models page for the full ranking.
Use our token counter to measure your typical prompt and response sizes, then multiply by the model's per-token price. Our cost calculator can automate this based on your expected monthly usage.
It depends on your usage volume. For light use (under ~100 messages/day), subscriptions are usually cheaper. For heavy or programmatic use, API access is typically more cost-effective. Use our subscription calculator to compare.
