EvoSQL framework enhances Text-to-SQL with critic-generator co-evolution

Researchers have developed EvoSQL, a novel framework designed to enhance Text-to-SQL capabilities by treating SQL synthesis as an iterative process between a generator and a critic. This system incorporates a memory component to store and verify SQL candidates, utilizing both execution signals and LLM-based critique for refinement. EvoSQL also includes a Self-Distillation Policy Optimization (SDPO) stage to fine-tune coding LLMs with execution-aware supervision, demonstrating significant improvements on benchmark datasets like Spider and BIRD, particularly for open-source models such as Qwen3-4B and Qwen2.5-Coder-3B.
