A new benchmark called SpecBridge has been developed to identify instances where text-to-SQL models make implicit choices without explicit user instruction. These models can provide a plausible numerical answer that differs from the user's intent due to unstated decision-making, such as choosing between counting rows or distinct entities. Standard benchmarks fail to detect this ambiguity because they evaluate against a single correct interpretation. SpecBridge addresses this by presenting three variations of a request: one leaving the choice open, and one for each possible interpretation. The results show that while models can compute different interpretations when explicitly asked, they often fail to provide all interpretations for open-ended requests, sometimes without acknowledging the ambiguity.
