Showing 46 models • Prices per million tokens • Updated March 2026
AI providers like OpenAI, Anthropic, and Google charge based on tokens — chunks of text that their models process. On average, one token equals approximately 4 characters or ¾ of a word. Every API call has two cost components:
Pricing varies dramatically across models. For example, GPT-4o costs $2.50 per million input tokens, while GPT-4 Turbo costs $10 — a 4x difference for similar quality on many tasks. Choosing the right model for your use case can save you 30-60% on your monthly AI bill.
Most developers don't realize how quickly AI API costs add up. A single GPT-4 call might cost $0.03, but at 100,000 requests/month, that's $3,000. Switching to GPT-4o-mini for suitable tasks could reduce that to $60 — a 98% saving.
Our calculator lets you paste your actual prompt and see the real cost across every major model, helping you find the most cost-effective option before writing a single line of code.
We track pricing for 50+ models across 11 leading AI providers: OpenAI (GPT-4o, GPT-4.1, o3, o1), Anthropic (Claude Sonnet 4, Claude 3.5, Claude 3 Opus/Haiku), Google (Gemini 2.5 Pro/Flash, Gemini 2.0), Mistral (Large, Small, Codestral), Meta (Llama 4 Maverick/Scout, Llama 3.3), DeepSeek (V3, R1), xAI (Grok 3), Cohere (Command R+), Amazon (Nova Pro/Lite/Micro), and Perplexity (Sonar Pro).
We estimate tokens using the standard ~4 characters per token ratio, then multiply by each model's published per-million-token pricing for both input and output. Pricing is updated regularly from official provider sources.
We support 50+ models across 11 providers: OpenAI (GPT-4o, GPT-4.1, o3, o1), Anthropic (Claude Sonnet 4, Claude 3.5, Claude 3 Opus), Google (Gemini 2.5 Pro, Gemini Flash), Mistral, Meta Llama 4, DeepSeek, xAI Grok, Cohere, Amazon Nova, and Perplexity Sonar.

Token estimation uses a ~4 char/token approximation. Actual costs may vary by 5-15% depending on the tokenizer. For exact token counts, use each provider's official tokenizer. The per-token prices reflect the latest published rates.
Yes! AI Cost Guard provides SDKs for TypeScript and Python, a CLI, and a VS Code extension that automatically track every API call, giving you real-time dashboards, budget alerts, and AI-powered optimization recommendations.
