# BYOK, Code Mode & Sensitive Data

**Date:** 2026-04-12
> Bring your own LLM keys, generate reusable automation scripts, and pass secrets securely.

---

## Bring Your Own Key (BYOK)

Use your own LLM API keys with V3 sessions. Your rate limits, your pricing, full control.

## Code Mode

The agent writes you a **reusable Python script** instead of just completing the task once. Re-run it tomorrow, in a cron job, with different inputs.

## Sensitive Data

Pass secrets to the agent securely. Kept out of logs, traces, and recordings.
