Large Language Model Multimodal Support
Salesforce-managed models have different levels of support and limits for including JPG, PNG, or PDF files in a model request.
Request Limits
To ensure quality of service, we have some limits for multimodal model requests. These limits apply to all Salesforce-managed models.
- Maximum total file size per request: 15MB
- Maximum number of files per request: 10 (any combination of JPG, PNG, or PDF)
- Maximum number of PDF files per request for Bedrock: 5

1 A geo-aware model, such as GPT 4 Omni, uses OpenAI or Azure OpenAI to service LLM requests. Because Azure OpenAI doesn't support PDF input, you can't send a PDF in a request to a geo-aware model. For more information, see Geo-Aware LLM Request Routing on the Einstein Generative AI Platform.
Model Provider File Size Limits
Some model providers have extra limits for individual file size. The next table gives more details on these extra file size limits.
| Model Provider | File Size Limits |
|---|---|
| Bedrock (Amazon and Anthropic) |
|
| Vertex AI (Google) | 7 MB per JPG or PNG |
Einstein Trust Layer Support
If a PDF is uploaded as a binary file in a model request, Einstein Trust Layer protections are not applied. To apply Einstein Trust Layer protections, you must extract the contents of the PDF and send the contents in a prompt in text format. Similarly, Einstein Trust Layer protections are not applied to JPG or PNG images.
