Braintrust, an AI-powered platform for software development, is using OpenAI's Codex to automatically turn customer requests into code. Engineers at Braintrust pair Codex with the GPT-5.5 model to speed up coding tasks and run experiments. This integration allows developers to focus on higher-level thinking rather than writing boilerplate code. --- Why it matters: This matters because it shows how AI can be used to augment human development work, freeing up engineers to focus on more complex problems and improving overall efficiency in software development.
