Philipp Schmid, an AI Developer Experience engineer at Google DeepMind, posted a short screen recording of Google AI Studio turning a single prompt about cereal pouring order into a complete two-minute talk radio segment, complete with script, multiple synthetic voices, and background music generated without any external editing tools.
Milk first or cereal first? I'm a cereal-first person. Apparently cereal acts as "a baffle" that stops milk from splashing, but pouring milk first causes a perception bias that leads to overeating. Wdyt?
This is all generated by Gemini via a single prompt built on Managed Agents. The script, the voices, the background music. One prompt.
Free to try in AI Studio.
A single API call or Playground interaction starts an autonomous agent in an ephemeral Linux environment that has access to code execution, search, and file tools, then follows its own plan-observe-iterate loop until the audio file is assembled.
Google published open-source templates that include the exact instructions and persona files needed for radio-style output, so anyone with access to AI Studio can load the same setup rather than building the agent logic from scratch.
Users are excited by Gemini generating a full radio show from a single prompt in AI Studio because it produces amazing and sensible everyday debates.

@_philschmid I’m a cereal without milk person, is this topic covered?

@_philschmid Always cereal first! The next one should be pineapple on pizza, yes or no? 😆

Amazing! And... Was it made by 3.5?
@_philschmid ....people do milk first?
@fofrAI @_philschmid Cinnamon toast milk and protein powder is all I require.
@_philschmid Cereal first is just correct. Honestly the more interesting part is that it generated a sensible everyday debate from a single prompt, which is exactly the low-stakes demo that builds more trust than any benchmark.
@_philschmid Single-prompt app generation is fun — the production gap we keep hitting is reproducibility. Regenerate a week later and behavior drifts. Does Managed pin model versions per applet, or is each generation best-effort? That answer decides whether teams can actually ship these.
@_philschmid Audio quality is probably past the threshold where listeners notice it's synthetic. That's the actual unlock for voice agents, not the model improvements.
