<p>Author here. High-level:<p>- Problem: AI UI generators are high-fidelity by default → teams bikeshed aesthetics before structure is right.<p>- Idea: use ASCII as an intentionally low-fidelity “layout spec” to lock hierarchy/flow first.<p>Why ASCII:
- forces abstraction (no colors/fonts/shadows)<p>- very fast to iterate (seconds)<p>- pasteable anywhere (Slack/Notion/GitHub)<p>- editable by anyone<p>Workflow:<p>- describe UI → generate ASCII → iterate on structure/states → feed into v0/Lovable/Bolt/etc → polish visuals last<p>It also facilitates discussion:<p>- everyone argues about structure/decisions, not pixels<p>- feedback is concrete (“move this”, “add a section”), not subjective<p>More advanced setups could integrate user/customer support feedback to automatically propose changes to a spec or PRD, enabling downstream tasks to later produce PRs.</p>

<p>Carlos here, sole dev and product at the NIUS.TV.<p>We have taken a similar approach on NIUS.TV. We've even taken it further by synthesizing an AI anchor.<p>Check it out:<p>- <a href="https://twitter.com/nius_tv" rel="nofollow">https://twitter.com/nius_tv</a><p>- <a href="https://twitter.com/beyondearthtv" rel="nofollow">https://twitter.com/beyondearthtv</a><p>The way we synthesize our videos is a little different from Baidu in practice, but similar on a high level.<p>For video synthesis we use an event-driven architecture using K8s jobs, and a custom job scheduler built in-house that manages all the steps of the video creation process.<p>Additionally, because GPUs are expensive and knowing that we synthesize our stories in batches through the day, we built a k8s-cluster-builder, that spins up and down the k8s cluster based on pending stories. This saves us a tremendous amount of cost per month, as the cluster only runs when there is actual work for it. As a bootstrapped project, costs are really important.<p>Our current video synthesis pipeline is comprised of 20+ steps, this includes speech-synthesis, image generation, speech+text aligners (for captions), language models, text generation, among others.<p>From my experience building the product, and despite the fact that AI is expensive (training wise), it is feasible to build AI-powered products using off-the-shelf DL technology without having large resources.</p>
