ExCoT
Snowflake’s AI research team introduces ExCoT, the first model in the Arctic Text2SQL family. ExCoT is a novel framework that combines CoT prompting with SQL execution-based DPO, using execution results — not human preferences — as the feedback signal. This enables scalable, high-quality model optimization without requiring expensive human annotations.
Based on our internal testing, ExCoT delivered state-of-the-art results on the BIRD-test benchmark, achieving best-in-class performance in the single-model, single-inference category using only public datasets (BIRD and Spider) and no additional Text2SQL data:
Arctic-ExCoT-70B (based on LLaMA 3.1 70B) improved execution accuracy on the BIRD-dev set from the base model’s 57.37% to 68.51%. Arctic-ExCoT-32B (based on Qwen-2.5-Coder 32B) achieved similarly strong gains.
Both models significantly outperformed larger open-weight models, such as Mistral 123B, and even proprietary systems including GPT-4o and Claude 3.5 — achieving over 12 percentage points of improvement.
