Bring Your Own Keys (BYOK)

BYOK is a feature available on all plans that allows you to use your own LLM provider API keys for rollout operations:
  • Configure your API keys for OpenAI, Anthropic, Google, and other providers
  • Rollout costs are charged directly to your provider account
  • Synth AI tracks BYOK usage separately for analytics
  • You pay your provider directly for LLM tokens
When using BYOK, rollout costs bypass Synth credits entirely. This is useful if you have existing provider relationships or want more control over costs.

Usage-Based Pricing

Beyond the included credits, usage is billed based on:
  • Rollout tokens: Policy model tokens consumed during training
  • GPU compute: For fine-tuning workloads
  • Inference: Graph inference calls (10% margin on token costs)

FAQ

Rollout credits cover the cost of running your policy model during prompt optimization and graph training. Credits refresh monthly and unused credits do not roll over.
Non-rollout usage includes: running evals, graph inference (completions API), and other platform features that don’t involve training rollouts.
Yes. Plan changes take effect immediately. When upgrading, you’ll be prorated for the remainder of the billing period.
Jobs will be paused until you add credits or the next billing cycle begins. You’ll receive email notifications as you approach your limit.
BYOK is available on all plans. When you configure your own API keys and use them for rollouts, the costs go directly to your provider account instead of using Synth credits. Your plan’s other benefits (unlimited non-rollout, team features, etc.) still apply.
