Braintrust vs Lambda Pricing (2026)

Which one is cheaper?

One or both use custom pricing, so it depends on your specific needs.

Can I use either one for free?

Braintrust has a free plan. Lambda doesn't — you'll need to pay from day one.

How do they charge?

Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.

Which one is a better deal?

Depends on what you need. Braintrust: At $249/mo, they're priced accessibly for mid-stage AI teams but not trying to be the cheapest eval tool in the room — they're positioning against the 'build it yourself' crowd and tools like LangSmith or Weights & Biases. The startup discount (6–12 months free on Pro) signals they're actively trying to land early-stage AI companies before competitors do. Lambda: Lambda positions as a serious alternative to hyperscalers (AWS, GCP, Azure) for ML teams who want raw GPU access without cloud markup or complexity. They're not the cheapest bare-metal option, but the no-egress-fees policy and 1-Click Clusters are a direct shot at teams burned by AWS networking costs.
