Limitations & when to consider alternatives
Known limitations
- Usage limits on the free plan. The Hobby plan is limited to 10,000 add requests and 1,000 retrieval requests per month.
- Per-request custom categories are unavailable on the managed API. Custom categories must currently be configured at the project level rather than overridden on individual add requests.
- Document and image formats are limited. Supported multimodal inputs include common images, MDX, TXT, and PDF documents; PDF support is documented through URLs.
- Image size limit. The open-source multimodal documentation describes uploads larger than 20 MB as rejected.
- No model fine-tuning. Mem0 provides custom extraction instructions and categories, but its documentation does not describe fine-tuning or training model weights.
Look elsewhere when
- You need a native iOS or Android application.
- You need a downloadable Windows, Mac, or Linux desktop application.
- You need a tool that generates or edits code directly.
- You need fine-tuning of model weights on your own data.
