Braintrust introduces its AI evaluation platform with beta customers

Evaluation before broad commercial availability

Braintrust’s introduction described running evaluations over versioned datasets and comparing results in a shared interface, with prompt experimentation and deployment in a customer’s cloud. The milestone is the introduced platform and beta use, rather than general commercial availability. The visible post dates the introduction to September 28, while embedded Article metadata says September 12; same-day first-hand coverage supports the bounded September 28 announcement. [1][2]
