Yes. The maximum system prompt size for ElevenLabs Agents (Conversational AI) is 2MB. This total includes your agent’s instructions, any knowledge base content you force into the prompt, and other system-level context. Note that the selected LLM’s context window still applies, so very large prompts or too many “Prompt”-mode documents can exceed context; use RAG to retrieve only relevant snippets when needed.

Custom LLM extra body -> max_tokens -> 100
