What is BYOK?
Understand LinkedGrow's Bring Your Own Key model, how it works, why it saves money, and how it compares to competitor pricing.
Bring Your Own Key explained
BYOK stands for Bring Your Own Key, and it is how LinkedGrow approaches AI-powered content creation. Instead of bundling AI costs into an expensive subscription with generation limits, LinkedGrow lets you connect your own API key from providers like OpenAI, Anthropic, Google AI, or Kimi.
You pay your LinkedGrow subscription for the platform features, and you pay the AI provider directly for actual usage at their wholesale API rates. Nothing is marked up along the way.
How it works
- Choose an AI provider - Pick from OpenAI, Anthropic, Google AI, Grok (xAI), Perplexity, or Kimi
- Get your API key - Create an account at the provider's website and generate an API key
- Add billing - Set up a payment method with the provider (pay-as-you-go)
- Paste your key in LinkedGrow - Go to Settings > AI API and enter your key
- Start generating - Create unlimited posts, ideas, hooks, and more
The AI provider charges you based on actual usage. Each post generation typically costs $0.001 to $0.05 depending on the model you choose.
Why BYOK saves money
Most LinkedIn tools bundle AI into the subscription and cap how much you can generate. Once you reach the cap you either stop or pay for more.
Two different AI bills sit behind LinkedGrow, and only one of them is yours:
| Who pays | What it costs you | |
|---|---|---|
| Everything the agents think: finding leads, scoring them, writing messages | LinkedGrow | Included in the plan |
| Everything you generate: posts, carousels, hooks, ideas | You, on your own key | $2-4 a month for most people |
So the content side is unlimited at cost price. Generate 10 posts a month or 200, you pay your provider for exactly what you used, and you choose the model.
There is no cap on how much content you create, and no markup on the AI that creates it.
