# FAQ

> Common questions about guest mode, privacy, wallets, and the API.

<AccordionGroup>
  <Accordion title="Do I need an account to use LETHE?">
    No. Guest mode gives you 3 free messages per network with no signup. Sign in only if you want chat/Studio history synced across devices. See [Getting Started](/user-guide/getting-started).
  </Accordion>

  <Accordion title="Is my data private today?">
    Guest history stays in your browser's `localStorage` and never reaches LETHE's servers. Signed-in history is stored in a regular (unencrypted) Postgres database scoped to your account. The TEE-based confidential inference and attestation-of-deletion described on the landing page are **not implemented yet**. See [Privacy Model & TEE](/roadmap/privacy-and-tee).
  </Accordion>

  <Accordion title="Why do I need a wallet?">
    Connecting a wallet at [`/cli`](https://asklethe.ai/cli) raises your daily message limit (3/network → 50/day) and issues a portable API key. It's a quota mechanism today, not a payment. See [x402 Micropayments](/roadmap/x402-micropayments) for the planned pay-per-call model.
  </Accordion>

  <Accordion title="What models are available?">
    Two public ids: `lethe` (text, 1M context) and `lethe-vision` (multimodal). Claude Code's default model ids and any `claude-*` id are aliased to `lethe` automatically. See [Models](/api-reference/models).
  </Accordion>

  <Accordion title="Is the API OpenAI-compatible, Anthropic-compatible, or both?">
    Both. `/v1/chat/completions` and `/v1/responses` follow OpenAI's request/response shape; `/v1/messages` and `/v1/messages/count_tokens` follow Anthropic's. Same auth, quota, and model ids across all four. See [API Reference](/api-reference/quickstart).
  </Accordion>

  <Accordion title="What happens to the $LETHE token and TEE features?">
    Both are on the roadmap, not live. See [Privacy Model & TEE](/roadmap/privacy-and-tee), [x402 Micropayments](/roadmap/x402-micropayments), and [\$LETHE Token](/roadmap/lethe-token) for current status.
