Plan a Staged Launch of a New AI Feature at Perplexity, From Dogfood to Full Release
Company: Perplexity
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Perplexity has built a new feature. Explain how you would take it from a finished build to full availability for the users it is meant for.
```hint Let the risk set the pace
A new feature in an answer engine can fail in ways a button change cannot: wrong answers at scale, a jump in inference cost, a bad output that spreads online. Work out what could go wrong with this feature and let that decide how many stages you need and what each must prove.
```
### Clarifying Questions
- What kind of feature is it: a change in how answers are generated, such as a new model, a new answer mode, or a capability that takes actions for the user?
- Who is it for: free users, paid Pro subscribers, enterprise customers, or everyone?
- Is there a fixed date to hit, such as a public announcement or a competitor launch, or can the ramp be gradual and quiet?
- Is there enough inference capacity to serve all intended users at once, or does capacity limit how fast we can ramp?
### What a Strong Answer Covers
- Readiness checks specific to an AI feature: offline evaluation, adversarial testing, cost and capacity planning, and a kill switch.
- A staged plan from internal use to full launch, with entry and exit criteria agreed before each stage.
- Success metrics and guardrails, measured with a controlled experiment during the ramp.
- Go-to-market choices: which users get it first, free or paid, and how and when it is announced.
- Monitoring, rollback and post-launch iteration driven by feedback on output quality.
### Follow-up Questions
- Midway through the ramp, quality looks good but inference cost per query is well above plan. Do you keep ramping, and what would you change?
- A competitor announces a similar feature while yours is still in beta. Do you speed up?
- After full launch, a screenshot of a badly wrong output from the feature spreads on social media. What do you do in the first day?
Overview: A product manager question on how you would roll out a new feature at Perplexity. It tests launch readiness for AI features, staged exposure with clear exit criteria, experiment-based measurement with guardrails, go-to-market timing, and monitoring and rollback plans.
