Short answer: large uploads get “cut off” because of enforced knowledge‑base size limits.
Non‑enterprise workspaces have a total knowledge‑base cap of 20MB or 300,000 characters. If an upload would exceed that, only part of the content can be stored/used, which can appear truncated. (elevenlabs.io)
If you attach a document to an agent without RAG, only up to ~300KB per item can be assigned to the agent. Enabling RAG raises the per‑item assignment cap to 10MB. (help.elevenlabs.io)
For RAG itself, there are additional per‑workspace indexing limits by plan (e.g., Free 1MB → Enterprise 1GB). Hitting these limits can prevent full indexing of large files. (elevenlabs.io)
What to do
Split big documents into smaller, focused files before uploading. (elevenlabs.io)
Enable RAG for the agent (to use larger per‑item sizes) and ensure your plan’s RAG indexing limits aren’t exceeded. (help.elevenlabs.io)
If you need higher limits, consider an enterprise plan. (elevenlabs.io)
