Basalt, #1 AI observability tool for teams, is launching its brand new Agent Builder : prototype, test, and deploy complex AI flows composed of multiple prompts, and run them through a dataset of scenarios.
Thanks Nicolas for the hunt !
I’m François, co-founder of Basalt, and together with the team we’re super excited to share our brand new feature: the Agent Builder 🚀
What pain are we solving ?
We're experts in AI observability, and along the way we noticed something important: engineers and PMs want to prototype AI agents before shipping them, but workflow builders are not made for evaluations.
What’s new with our Agent Builder
Basalt's Agent Builder is the easiest way to design, test, and optimize complex AI flows built from sequences of prompts and actions.
👉 Create and customise your own flows
👉 Chain prompts and actions with ease
👉 Run each prompt on the best-suited model
👉 Set custom evaluation criteria for each step
👉 Measure performance on hundred of real case scenarios with dedicated datasets
Stop testing prompts in isolation. Turn your flow into a single, end-to-end workflow you can evaluate thoroughly, and then deploy with confidence.
Hope you enjoy it !
❤️ from the Basalt team
