Limitations & when to consider alternatives
Known limitations
- Free plan agent limit. The Free plan is limited to three stateful agents.
- Pro plan agent limit. The individual Pro plan supports up to 20 stateful agents.
- Usage can incur additional charges. Letta Auto and model usage can continue on pay-as-you-go pricing after included quotas are exceeded.
- Cloud execution uses configured computers. Cloud agents run in cloud sandboxes or other registered computers; local-file access depends on the selected computer.
- Provider costs may apply. Bring-your-own API keys route usage through the external model provider, while Letta API usage is usage-based.
Look elsewhere when
- You need a native iOS or Android app.
- You need a browser extension rather than browser chat.
- You need documented multilingual controls.
- You need vendor-provided fine-tuning of model weights.
