LegalOn Technologies, using OpenAI's Codex and various GPT-6 and GPT-6.1 models, reduced estimated daily AI costs by 65% by matching models to task complexity and implementing budget controls. The company maintained development speed despite restricting use of high-performance models, shifting from unlimited use of GPT-5.5 to selective use of GPT‑6 Luna, GPT‑6.1 Sol, and GPT‑6 Astra.
