the chonk just opened its weights. mistral large 4, in public preview since oct 6, packs 1.05 trillion total parameters with 49 billion active and a 1 million token context.
the european frontier now costs 1.36 per million.
Context
Verified date: Mistral's announcement, Introducing Mistral Large 4, and VentureBeat are dated Oct 6, 2026. Mistral calls it a 1 trillion-parameter natively multimodal model with 52 billion active parameters, and its docs list 1.05T total, 52B active and a 1.6B vision encoder. It launched as a public preview, and open weights are planned for late October per AIstify.
TokenCost (Oct 10, 2026) lists $1.36 per million input tokens at list price and a sale price of $0.68 input and $2.09 output. llm-stats lists a 1M token context.
The Oct 6 public preview, the 1.05 trillion total parameters and the 1 million token context match. Mistral's docs say 52 billion active parameters, not 49 billion. The post's 'opened its weights' is not supported: AIstify says open weights are planned for late October, and the model is a public preview. The $1.36 is the list input price per million tokens; TokenCost shows a sale price of $0.68 input and $2.09 output. 'The european frontier now costs 1.36 per million' is the author's opinion.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.
