Le Chat (Mistral) vs ChatGPT: the European alternative

Mistral’s Le Chat or ChatGPT: prices, free plans, a European provider, training on your chats and the Mistral Large 4 API, with official sources.

By Cognenza editorial team · Updated · Euro prices as published for Spain; they may differ in your country.

Mistral Large 4 (preview) and Le Chat: Entry under review: some data is not officially published yet.

Verdict

Le Chat is the European alternative if you want a provider subject to the GDPR; ChatGPT wins on features. Both train on your chats by default and both let you turn it off.

Main differences

  • Provider: Mistral is French; OpenAI is American.
  • Price: Le Chat Pro costs USD 14.99 per month excluding tax; ChatGPT Plus, €23 per month.
  • Open models: Mistral publishes the weights of its small models under Apache 2.0 and has announced those of Large 4.
  • API: Mistral Large 4 (preview) costs USD 1.36 input and USD 4.18 output per million tokens; GPT-6.1 Sol, USD 2.00 and USD 10.00.
