Mistral Large 4: useful in French, weak for coding
In brief
According to Journal du Net, Mistral AI released Mistral Large 4, a model whose weights can be downloaded, with 1,000 billion parameters. Compared with GPT-6 Luna and GLM-5.3, it holds up on legal and finance benchmarks but lags on coding. List API prices are at the low end, with a 50 percent discount for the first 15 days.

What it changes for an SME
For an SME of 10 to 250 people, this is not a reason to switch everything. If coding agents or terminal work drive your savings, Journal du Net finds Mistral Large 4 clearly behind GPT-6 Astra and GLM-5.3. It may be worth a look for French text, legal tasks or cybersecurity, at API rates close to GLM-5.3 and far below GPT-6 Astra. GPT-6 Luna remains much cheaper, so run a short test on your own files before you change supplier.
What you can do
- Run the same French and legal prompts on Mistral Large 4, GLM-5.3 and GPT-6 Luna using your real documents before you change tools.
- Check your volumes against the prices Journal du Net reports: Mistral Large 4 matches GLM-5.3 at list price, is 50 percent off for 15 days only, and stays far above GPT-6 Luna.
- If software generation or terminal agents matter to you, keep your current stack: the review places this model well behind on those tasks.
