Music AI isn't just for generating tracks—one producer turned Suno into a $10/month communication tool that saves $300 per song. Here's the counterintuitive workflow that's actually worth stealing. The Setup After eight years of making music, Alexander Kumar knows exactly how a track should sound. The verse should hit a certain way. The breath should fall in a specific spot. The flow needs to pull back right before the hook lands. But explaining that with words? Tricky. Humming doesn't help when you're not a singer. And hiring vocalists just to test ideas before committing runs $100+ per hour. So he did something mildly controversial in music circles: he started using Suno. But not to generate music. To generate clarity. Suno As a Communication Tool Suno is an AI tool that generates music from text prompts. Type a style prompt → get a finished track. But that's not what Suno does for Alexander.

ChatGPT 5.2 isn't flashy in the way the internet likes it. There was no viral demo, no trending reels, and nobody fainted.
| TL;DR for Builders & Researchers | |
| ChatGPT 5.2 is optimized for reliability and variance reduction, not maximum creative upside. | |
| Compared to 5.1, it trades expressive flair for: | |
| • stronger instruction persistence | |
| • fewer derailments in long conversations | |
| • dynamic reasoning depth instead of always “thinking harder” | |
| This makes 5.2 better for production workflows, specs, coding, governance, and long-running tasks, but worse for creative drafting and lyrical writing. | |
| Before joining this debate, I ran a substantial, multi-hour test involving 8,100 lines of dense, intentionally confusing input and tripwire prompts, and spent a few more hours mapping the misconceptions I kept seeing online. |

AI makes it easy to ship faster — but that’s exactly how product judgment erodes.
This gist gives you the opening section of the post so you can rethink how you build, especially if you’re vibecoding your way through features.
GitHub friends: this is a fast, practical cut of my Substack guide on vibecoding securely—trimmed for builders who ship at 2 a.m. and prefer checklists to lectures.

The transformation is unmistakable: Substack has evolved from a simple newsletter platform into a thriving ecosystem where indie builders are creating products, launching businesses, and earning substantial revenue. This shift represents one of the most significant developments in the creator economy of 2025, fundamentally changing how independent entrepreneurs build and monetize their work.
Substack surpassed 4 million paid subscriptions in 2024, with over 50,000 publishers generating income on the platform. But the real story isn't about subscription revenue—it's about the indie builder economy that's emerged around it. Creators are no longer just writing newsletters; they're shipping tools, templates, courses, and digital products that generate significant revenue streams beyond traditional subscription models.[1][2][3]
The platform's growth trajectory shows why builders are flocking here: it added 1 million paying sub
