Common questions
Are the benchmarks really free?
Yes. Every public benchmark, model page and comparison is free to browse with no account.
What do I get on the waitlist?
Early access to the workbench, launch pricing, and a say in what we build next.
How is this different from a leaderboard?
Leaderboards rank models in general. Spring Prompt scores models on your prompt, your test cases and your definition of good.
Do you store my prompts?
Your prompts and test data are yours. See our privacy policy for details.
