# How Braintrust turns customer requests into code with Codex

# Claim

How Braintrust engineers use Codex with GPT-5.5 to run experiments and code faster.

# Relevance

Appendix III, section four: enterprise deployment evidence

# Oracle Verdict

OpenAI is describing a frontier or production capability that pushes directly on the thesis. The important signal is not the marketing language; it is the widening set of tasks now being routed through model-driven execution rather than ordinary software or headcount.
