Why this exists

The same open-weight model often costs several times more at one provider than at another, and nobody publishes those prices side by side. This repository does, every day, as plain files you can load into a spreadsheet, a notebook or your own app.

3,077 prices for 2,019 models from 59 providers, last updated 2026-11-14.

Same model, very different price

The ten most widely sold models today, from the cheapest to the most expensive provider:

Blended list price per 1M tokens (3 input : 1 output), standard tier. The ten models sold by the most providers; typical is the median provider.

What it looks like on AISelect.online

The website turns this dataset into calculators, rankings and head-to-head comparisons.

Use it

curl + jq: every provider of one model, cheapest first

curl -s https://raw.githubusercontent.com/Liutasil501/ai-api-prices/main/ai-api-prices.json \
  | jq '[.prices[] | select(.model_slug=="gpt-oss-120b")] | sort_by(.input_usd_per_1m_tokens) | .[] | {provider, input_usd_per_1m_tokens, output_usd_per_1m_tokens}'

Python / pandas

import pandas as pd

prices = pd.read_csv("https://raw.githubusercontent.com/Liutasil501/ai-api-prices/main/ai-api-prices.csv")
llm = prices[prices.category == "text"]
print(llm.groupby("model")["provider"].nunique().sort_values(ascending=False).head(10))

JavaScript

const { prices } = await fetch("https://raw.githubusercontent.com/Liutasil501/ai-api-prices/main/ai-api-prices.json").then((r) => r.json());
const cheapest = prices.filter((p) => p.model_slug === "claude-sonnet-5-5").sort((a, b) => a.input_usd_per_1m_tokens - b.input_usd_per_1m_tokens)[0];

Price history: the commit history is the price history. git log -p ai-api-prices.csv shows every change since tracking started.

Ask your AI assistant (MCP server)

This repository is also an MCP server, so Claude, Cursor or any MCP client can answer "what does gpt-oss-120b cost at each provider?" from today's data. It reads the daily file from aiselect.online (this repository's copy as fallback); no API key, no sign-up. Needs Node.js 18 or newer.

Claude Code

claude mcp add ai-api-prices -- npx -y github:Liutasil501/ai-api-prices

Claude Desktop, Cursor and other clients (claude_desktop_config.json, .cursor/mcp.json):

{
  "mcpServers": {
    "ai-api-prices": { "command": "npx", "args": ["-y", "github:Liutasil501/ai-api-prices"] }
  }
}

Then ask: "Which provider sells Llama 3.3 70B cheapest, and what would 50M input and 10M output tokens a month cost there?"

Columns

How prices get in

Prices come from open, MIT-licensed datasets (LiteLLM, models.dev, Portkey Models) and from pricing pages checked by hand. Before a value is published it has to pass guards:

• it must appear on two consecutive daily runs,

• a jump above 50% is published only after it holds for seven days, and zero prices and 10x jumps are skipped as dataset errors,

• every provider is classified by hand (resellers and gateways are not listed as providers),

• prices billed in euros are converted to US dollars at the European Central Bank's daily rate.

These are standard list prices, not quotes. Batch, committed-use and negotiated discounts are not included. Check the provider's page before you buy. The full method is on the methodology page.
