One Prompt. A Feature Built and Tested. | Ramp × GPT-6 Astra

3 min video3 key momentsWatch original
⚡
TL;DR

Ramp's AI lead built a routing feature in 27 minutes using GPT-6 Astra with a single vague prompt, no step-by-step instructions needed.

Key Insights

1

Worked with zero instructions — Astra handled a vague feature request (routing strategies by API key granularity) with zero explicit instructions on UI navigation — it inferred the exact clicks and workflows needed.

2

Self-verified without asking — The model self-verified the changes on mobile view without being asked, catching edge cases the engineer didn't explicitly request.

3

Verification, not just coding — Computer use is shifting from a research toy to a low-risk change verification tool — Ramp sees this as the path to letting customers automate their own receipt fetching.

Deep Dive

One prompt, a feature shipped

The Ramp AI lead describes Astra as a coworker you can hand off vague tasks to and check back in 10 or 15 minutes later. He submitted a single feature request: implement routing strategies controls by API key granularity. No step-by-step instructions. Astra spent 12 minutes building it, then another 15 minutes validating the changes. The model found the exact settings menu, made the changes, and even tested on mobile view without being asked. The speed and independence impressed him most — Astra asked for nothing beyond that initial goal statement.

The roadmap: customer-facing automation

Ramp's bigger vision is getting computer use into customers' hands. Today they fetch receipts from merchant websites by manually prompting the model on where to click. Ramp wants to test Astra against a longer tail of merchant sites to see if the model's general web understanding is strong enough to eliminate those manual prompts. If it works, customers could trigger receipt pulls without Ramp having to hardcode every merchant's UI path. This moves computer use from an engineering convenience to a customer feature.

Takeaways

  • ✓Test vague prompts with Astra on low-risk product changes — let it infer the UI navigation rather than spelling out each step.
  • ✓Build verification checks into your automation loops; Astra will self-test edge cases if you give it room to explore.

Key moments

0:36One prompt, twelve minutes

“I had a feature request implement routing strategies controls by API key granularity and I said nothing else and it was able to know that the way this pops up is by clicking on one of the existing API keys”

1:48Self-verification on mobile

“Yeah. And verified it on like mobile view. That's awesome. Yeah. I didn't even ask for that.”

2:35Receipt automation next

“I'm excited to kind of test more with a long tale of merchants and see how Astra handles them. I think it'll have a better understanding of how most websites kind of operate.”
