Mistral AI in one minute
Mistral AI is the company; names such as Large, Medium and Small identify models. Vibe combines a chat assistant for work with a coding agent. Some model weights are downloadable, while other releases initially arrive through a service. Check each model’s status and licence.
Which models and weights are available?
On 8 October 2026, Mistral Large 4 is the latest Large release, in public preview since 6 October. Mistral says its weights will arrive at the end of October. They are therefore not yet downloadable on the review date, even though the announcement describes an open-weight model.
The model catalogue also includes Medium 3.5, Small 4 and Ministral 3. Licences differ: Medium 3.5 uses a modified MIT licence, while Small 4 and Ministral 3 use Apache 2.0. Being able to run a model yourself does not imply identical terms across releases.
Specialisations also include speech with Voxtral and document processing with OCR models. Choose a suitable model and distinguish understanding inputs from generating new content. A third-party model in Mistral’s API catalogue does not become a model developed by Mistral.
From Le Chat to Mistral Vibe
The current product page presents Vibe as a combination of an assistant for knowledge work and a coding agent. Le Chat is the work assistant’s earlier name. This is a product built on models, with search, documents, tools and available integrations.
For example, a consultancy gathers research notes to prepare a supported client presentation. A suitable Vibe environment can consult sources and assemble a draft. The consultant checks that conclusions follow from the evidence and that figures match the original files.
The same brand covers programming work. Repository access and running tests are features of the agent environment. They do not follow automatically from possessing model weights.
Business use and the European context
Its European origins are relevant to the offering and discussions about infrastructure and data management. They do not, by themselves, establish where every service processes data, which contract terms apply or which solution is best.
Mistral offers managed services and enterprise deployments on private or customer infrastructure. For a business, the choice involves internal knowledge access, permitted actions, administration and maintenance. Running your own installation brings different responsibilities from buying a subscription.
Compare a solution using your documents and workflow: can it locate a source, explain a discrepancy and submit a change for review? Those tasks are more useful selection criteria than a commercial claim about a single benchmark.
