Dropbox uses DSPy to turn AI evals into sharper, cheaper Chat answers
Dropbox leveraged the open‑source DSPy framework to turn LLM‑as‑judge evaluations into a feedback loop that fine‑tunes both its judges and the Dash chat system prompt. By calibrating judges with human labels and running DSPy’s optimization algorithms, the chatbot cut incomplete answers and token usage while keeping answer quality high.
