How Braintrust turns customer requests into code with Codex

Braintrust, an AI observability company, uses Codex (OpenAI's code-generation AI model) to quickly turn customer feature requests into working preview branches in minutes, with half the team adopting it within one month. The speed of Codex enables faster feedback loops with customers and allows engineers to test ideas in real time rather than letting requests sit in a backlog. Codex's ability to handle large amounts of text output without slowing down makes it more effective than other models for this workflow.
