Ramp engineers use the Codex model from OpenAI to speed up code reviews. They combine Codex with a version of GPT that has been fine-tuned for coding tasks (GPT-5.5) to get feedback on their code in minutes, rather than hours. --- Why it matters: This matters because it shows how AI can be used to accelerate software development and improve collaboration among engineers. By automating routine code review tasks, developers can focus on more complex problems and ship improvements faster. Source: https://openai.com/index/ramp
