LLM API Price Index, October 2026

What 1,000 requests cost across every listed LLM API model, by provider, as of 2026-10-23. Issue 1 of a monthly index (October 2026 = 100). Across 67 listed models from 4 providers, the median model costs $7.00 for 1,000 chatbot replies.

How it was collected

• Basket: every model the provider lists as current on its official pricing page with an input and an output price (retired models and embeddings excluded), from our dated snapshot of 2026-10-23.
• Chatbot workload: one reply of 1,500 input tokens and 400 output tokens at the standard price (no cache or batch discount).
• Agent workload: one coding-agent step of 40,000 input and 2,000 output tokens at the standard price.
• The index is the median basket cost divided by the first issue's median. A model joining or leaving the basket moves the index on purpose: it tracks what a buyer can actually pick.
• Per-model prices are in the companion dataset "LLM API prices".
