BYOK (Bring Your Own Key) decoupled
BYOK is decoupled from tier — any tier can toggle BYOK. With BYOK on, LLM calls use your own OpenAI / Anthropic / DeepSeek key, Vara doesn't burn tokens, quota doesn't count money. PRO + BYOK = PRO features + you pay the LLM provider direct, Vara only charges a service fee.
