AICost is an independent price desk for AI models, built around one question: what will this actually cost me? It tracks input, output and cache rates per million tokens for 300+ models from 30+ providers, including OpenAI, Anthropic, Google, Mistral, DeepSeek, Qwen and Kimi. Every price is traced to the vendor's own pricing page, dated, kept with its history, and made comparable across APIs, subscriptions and AI coding tools; corrections are published in a public log. Free, embeddable tools include an LLM API cost calculator, token counter, subscription-vs-API calculator and text-to-speech cost calculator, turning your usage into a real monthly bill. Side-by-side model comparisons show the true difference between options, and pricing guides cover AI coding agents such as Claude Code, Codex and Cursor.
