Tradeoffs to expect

Route

The consumer Vibe experience is hosted by Mistral. Self-hosting an open model requires separate weights, compatible hardware and software; it is not the same route as Vibe.

See the evidence

Privacy controls

Consumer inputs may be used for training subject to opt-out and product/account-specific retention terms.

See the evidence
How to switch

Get started

Use the consumer web or mobile app and check current availability; for local operation, select a specific Mistral open model and follow its model-specific deployment instructions and license.

Energy practices

5/10↑

Mistral’s 2025 LCA reported inference impacts for a historical 400-token Le Chat response. Le Chat was renamed and expanded as Vibe in 2026. The old figure is not a current Vibe or Medium 3.5 measurement. Vibe now offers Fast/Think and Work/Code modes, but no current energy sourcing or usage footprint.

See the evidence

Mistral’s LCA is unusually useful historical product evidence: it reports 1.14 gCO₂e and 45 mL water for a 400-token Le Chat response, following ISO/GHG Protocol methods and peer review. The product then changed into Vibe, and Medium 3.5 became a current model; therefore the historical metric cannot be transferred to today’s product or route. Under the common rubric it earns D2 for dated quantitative disclosure, while current Vibe’s Fast/Think and Work/Code controls earn C2 without proving savings.

1 + 2 reporting + 0 electricity + 2 controls = 5/10. This grade covers documented practices and transparency; it does not measure the energy or emissions of a request.

Current Vibe/Medium 3.5 request footprint; current model selection and routing by mode; location and facility; electricity mix; whether current modes reduce energy; update to historical LCA.

Reporting2/3
Mistral published a 2025 quantified LCA and inference estimate for a 400-token Le Chat response, with ISO/GHG Protocol method and third-party peer review. It predates Vibe and Medium 3.5; no current Vibe footprint is available. Per task instruction, this earns D2 only, not D3.
Electricity sourcing0/3
No quantified electricity sourcing or route-specific clean-power match is established for current Vibe or the historical Le Chat response.
Resource controls2/3
Current Vibe has a Fast/Think toggle and distinct Work/Code workflows; these are practical model-depth and task controls, but no physical reductions are measured.

Water disclosure

Water reporting has not been assessed for this choice.

Training data

3/10↑

Mistral’s privacy disclosure identifies public internet, third-party, curated, synthetic, internal and product-use data; its help center says it does not disclose training datasets. That is enough to assess disclosure weakness for the identified first-party family.

See the evidence

The first-party model family is identifiable, but the company explicitly withholds dataset identities and supplies no model-specific permission ledger. The low score measures this disclosure gap; consumer input opt-out is not counted.

1 + 1 source transparency + 1 permission + 0 creator controls = 3/10. This grades documented training-data safeguards, not a legal ruling.

The exact Vibe default model, dataset composition, third-party permissions and any creator-specific removal process remain undisclosed.

Source transparency1/3
Mistral names broad source classes but explicitly says the training datasets are not disclosed.
Documented permission1/4
The company describes a mixed data recipe without identifying licenses or rights bases for most source material.
Creator controls0/2
The reviewed sources don’t show creator controls over the underlying training data.

Your data & privacy

4/10↑

Mistral’s current consumer policy covers Vibe: inputs/outputs are retained until the user deletes the conversation or account, and inputs/outputs may be used for model training subject to an account opt-out. Temporary Chat is not used for training.

See the evidence

A user can object to training use of inputs and outputs, and Temporary Chat is excluded, but default retention lasts until deletion and ordinary activity may be used for training unless the user opts out.

Openness

4/10↑

Mistral renamed its consumer assistant Vibe. The hosted service provides web/mobile chat and productivity features; Mistral also offers an enterprise deployment option and open-weight models, including a self-hostable current model. These options do not make the default consumer service or all model routes openly reproducible.

See the evidence

Vibe has a real enterprise deployment option and its default Medium 3.5 model is open-weight and self-hostable; those increase openness. The consumer path remains a hosted service, and model weights, licenses, and the full product stack vary, so this is a partial/configuration rating rather than an end-to-end open-service claim.

Worker protections

2/10↑

Mistral publicly says its supplier code applies to goods and services and its Trust Center shows contractors acknowledge a code, but labor-specific provisions and outcomes were not publicly inspectable.

See the evidence

Mistral’s August 2026 help page states that its Code of Conduct sets standards suppliers are expected to follow for Mistral business and all supplier goods/services; the Trust Center lists contractor acknowledgment of the Code of Conduct. The public interface did not expose the code’s labor clauses or worker procedures, and no worker survey, audit, pay/conditions disclosure or remediation results were located. This supports limited credit for a supplier-code commitment only.

1 + 1 pay & conditions + 0 worker voice & remedy + 0 evidence & follow-through = 2/10. This grades documented worker safeguards, not a measured rate of mistreatment.

The supplier code’s detailed labor language and coverage of AI data workers, grievance route, monitoring and outcomes were not accessible from the public Trust Center.

Pay & conditions1/3
A supplier code is a stated business requirement, but its labor content and implementation were not publicly inspectable in this review.
Worker voice & remedy0/3
No public worker-specific voice or grievance mechanism was established in the accessible sources.
Evidence & follow-through0/3
The Trust Center shows contractor code acknowledgment but no labor-specific audits, remediation or outcomes.

Military ties

3/10Broad defense ties↑

Mistral AI publicly partners with defense AI company Helsing on joint development of vision-language-action models, and its current company page says it serves defense customers. A separate Airbus agreement includes military aerospace applications; specific Mistral model deployments in weapons systems are not established.

See the evidence

Mistral's announcement with Helsing describes joint development of next-generation AI systems for European defense, while Helsing's announcement links its military AI portfolio to Ukraine-deployed strike drones and fighter electronic-warfare capabilities. Mistral also identifies defense as a customer sector and Airbus says the partnership includes military aerospace applications. This is broad defense enablement, capped at 3/10; no binding weapons/surveillance prohibitions or military-use oversight outcomes are public in these sources.

1 + 0 use restrictions + 0 enforcement & oversight + 2 relationship disclosure = 3/10. Known defense ties lower this rating; safeguards can improve it within the relationship’s cap.

The sources don’t confirm which Mistral models, if any, are deployed in specific military systems, the operational purpose or safeguards, contract restrictions, or independent oversight. Helsing's existing strike systems are not evidence that Mistral models themselves control or target weapons.

Use restrictions0/4
The reviewed public partnership and company materials do not disclose binding restrictions on weapons, harmful surveillance, or military-intelligence use.
Enforcement & oversight0/3
No public military-specific review, enforcement mechanism, or independent outcome assessment was identified in the reviewed partnership materials.
Relationship disclosure2/2
Mistral and its partners identify the defense relationships and intended applications, including VLA model development and military aerospace, though no model-level deployment details or outcomes are disclosed.

Mistral publicly confirms joint defense-AI development and military-aerospace partnerships, but no source establishes its model in actual targeting or combat intelligence use. The relationship limits this grade to 3/10.
