Ada is the language behind flight controllers, missile guidance, satellite systems, and air traffic control. It's one of the most important languages in safety-critical software - and every major LLM i tested is subpar at it. I fine-tuned Qwen2.5-Coder-14B-Instruct using QLoRA on a compiler-verified dataset of 3,430 Ada/SPARK instruction pairs. Every single
