GPT vs Llama

This page compares what OpenAI and Meta charge through their APIs. Every price below carries the day we read it and links to the page it came from. We do not rank quality: we tell you what each model costs, and since when.

At the top of each range

• Among GPT models that carry a relayed score, the highest on the Artificial Analysis intelligence index is GPT-5.4, at 53.1, sold by OpenRouter at $15.00 per million output tokens.
• Among Llama models that carry a relayed score, the highest on the Artificial Analysis intelligence index is Llama 4 Maverick, at 9.3, sold by OpenRouter at $0.6525 per million output tokens.

The index is produced by Artificial Analysis and relayed through OpenRouter's catalogue. It is not our measurement; we record it as a level 4 source and show it next to the price we read. A model without a score here has not been scored yet, which is not the same as scoring low.
