Definition
BYOK (Bring Your Own Key) is the pricing model where the SaaS tool is just the orchestrator + UI, and the user supplies their own OpenAI / Anthropic / Perplexity API keys. The user pays each provider directly. Tools using BYOK can price the platform flat (no per-token markup), which is structurally cheaper.
Profound charges $499/mo for ChatGPT-only probing because they pay OpenAI per request. VectorCite ships multi-engine Deep Probe at any tier because users bring their own keys; we pay nothing per probe.
How to optimize
If you're an agency, prefer BYOK tools: your monthly bill becomes the underlying provider cost, not a 10x markup. VectorCite is BYOK-native at /app/byok.
