Braintrust, an observability and eval platform for AI products, says its engineers now use Codex with GPT-5.5 to turn customer requests into working previews quickly. Founder and CEO Ankur Goyal says the main shift is not only faster coding, but faster customer feedback.
Braintrust is a company that helps other teams check whether AI products are working well. Its engineers use Codex like a fast helper that can turn a customer idea into something visible very quickly.
Instead of writing down a request and waiting a long time, the team can make a quick test version and show it to the customer. It is like sketching a house plan and then building a tiny model right away so everyone can point at it and say what should change.
The main point is that faster tools let the team try more ideas. Braintrust says that speed helps it learn from customers sooner and build more useful things.
Analysis
What Braintrust says Codex changed
Braintrust says its engineers use Codex to take customer feature requests and turn them into preview branches in minutes. The company frames this as a faster way to show working ideas to customers instead of waiting for requests to move through a normal backlog.
Founder and CEO Ankur Goyal says the biggest gain is speed. In the article, he says Codex can produce terminal output quickly and that this speed changes how he uses it compared with other models. Braintrust says half of its team moved to Codex in one month.
A different workflow
Goyal describes a shift away from step-by-step prompting. Instead, he says he can write a test that demonstrates a problem, create a sandbox environment, and let Codex run in that environment. The article presents this as a way to make experiments cheaper and easier to run.
That matters because the team can test ideas in real time with customers. Rather than treating feature requests as items that wait for prioritization later, Braintrust says it can copy a request into Codex, build a preview branch, and discuss the result with the customer quickly.
The broader takeaway
The piece is less about a single feature and more about a workflow change. OpenAI is using Braintrust as an example of Codex helping engineers move faster from request to prototype, with the promise of more experiments and more customer problems solved. The article positions speed as the key factor that makes that loop practical.
Key points
- Braintrust says Codex helps engineers turn customer requests into preview branches in minutes.
- Founder and CEO Ankur Goyal says the biggest benefit is speed and a faster feedback loop.
- The company says half of its team moved to Codex in one month.
- Goyal says he can define a problem with a test and a sandbox, then let Codex work there.
- The article frames Codex as a tool for faster experimentation, not just faster typing.
