Why Compare LLM Prices in Messages Per Dollar?
Traditional LLM pricing is shown in dollars per million tokens ($/MTok), a metric that means nothing to most people. How many tokens is a conversation? What does $3/MTok actually cost you? LLM Bench converts every model's pricing into a simple number: how many messages you can send for one dollar. We start from a base of ~7,000 tokens per message (7,000 input + 7,000 output), which represents a realistic average across diverse use cases. This makes it easy to compare ChatGPT API pricing, Claude API costs, Gemini pricing, and hundreds of other models at a glance.
ChatGPT vs Claude vs Gemini for OpenClaw: Which Is Cheapest?
The cost of AI models varies dramatically. Budget models like GPT-4.1 Nano and Gemini 2.0 Flash offer hundreds of messages per dollar, making them ideal for high-volume OpenClaw tasks. Premium models like Claude Opus 4.6 and GPT-4.1 deliver fewer messages per dollar but offer superior reasoning and coding capabilities, perfect for complex OpenClaw workflows. Mid-range options like Claude Sonnet 4 and GPT-4.1 Mini strike a balance between cost and quality. Use the "Popular for OpenClaw" filter to see which models the community actually uses.
How We Calculate LLM Cost Per Message
Our formula is built on a realistic baseline, not guesswork. We use 7,000 input tokens and 7,000 output tokens as the average message exchange. Of course, usage varies: a quick question might only use 2,000 tokens, while a complex coding session can exceed 15,000. But 7,000 is the sweet spot that reflects how people actually use AI in production. The cost per message equals 7,000 multiplied by the sum of the input and output price per token. Messages per dollar is simply 1 divided by this cost. Using the same formula for every model ensures a fair, apples-to-apples comparison. All pricing data is fetched directly from the OpenRouter API and refreshed every hour.
