A 400M parameter vision encoder trained from scratch handles image understanding, while a 12B decoder based on Mistral Nemo handles text generation. The two components were trained together on interleaved image-text data, so visual and textual understanding are integrated rather than bolted together. The context window of 128K tokens accommodates multiple images alongside text in a single request. You can compare images, trace visual changes across a document, or cross-reference diagrams with their written descriptions. Variable aspect ratio support processes images at their native dimensions, which matters for charts, documents, and technical schematics where distortion degrades accuracy. On MMMU, Pixtral 12B 2409 scores 52.5% and achieves a 20% relative improvement in instruction following over comparable open-source multimodal models. Pixtral 12B 2409 ships under Apache 2.0. Mistral has designated Pixtral 12B 2409 as deprecated in favor of newer vision models, though it remains available through AI Gateway for existing integrations. ## [Copy link to heading](#what-to-consider-when-choosing-a-provider)What To Consider When Choosing a Provider - Configuration: Pixtral 12B 2409 processes images at native resolution without token waste. Pixtral 12B 2409 adapts token allocation to actual image dimensions, unlike models that resize all images to a fixed token budget. - Zero Data Retention: Zero Data Retention is available for this model. It is offered on a per-provider and model basis. See the [documentation](https://vercel.com/docs/ai-gateway/security-and-compliance/zdr) for details. - Authentication: AI Gateway authenticates requests using an [API key](https://vercel.com/docs/ai-gateway/authentication-and-byok#api-key-authentication) or [OIDC token](https://vercel.com/docs/ai-gateway/authentication-and-byok#oidc-token-authentication). You do not need to manage provider credentials directly. ## [Copy link to heading](#when-to-use-pixtral-12b-2409)When to Use Pixtral 12B 2409 ### Best for - Document question answering: Text and visual layout matter together - Chart and graph interpretation: Requiring both visual parsing and textual explanation - Multi-image workflows: Within a single request using the full context of 128K tokens - Native multimodal migration: For applications moving from vision-adapted text models - Apache 2.0 vision licensing: Teams requiring this license for a vision-capable model ### Consider alternatives when - Higher vision accuracy: You need top-tier performance (consider Pixtral Large) - Text-only workloads: Vision capability adds no value - Higher math or reasoning: You need stronger benchmark scores alongside vision ## [Copy link to heading](#conclusion)Conclusion Pixtral 12B 2409 brought native multimodality to the Mistral family as a ground-up integration of vision and language through a 400M encoder trained alongside the text decoder. Mistral has deprecated Pixtral 12B 2409. For teams with existing integrations, Pixtral 12B 2409 remains available through AI Gateway.
