Phase 0: Generative Media Fundamentals · 50 min · Python · fal.ai API

The Workflow-Not-Model Insight

The unit of work in production generative media is a workflow, not a model.

Real-world application: The workflow-not-model insight from a16z/fal.ai is the core mental model that separates engineers who understand production generative media from those who just prompt models.

What you will learn

Articulate the a16z/fal.ai insight: the unit of work is a workflow, not a model
Explain why chaining multiple models achieves production quality that single-model prompting cannot
Describe a 5-stage professional AI video workflow
Identify how fal.ai serves 600+ models to millions of users via workflow orchestration

Objective

Frame the medium, audience, constraints, and production economics before selecting a model. In the paired studio lab, build a 3-step workflow using fal.ai: (1) generate an image with FLUX, (2) upscale the image with Real-ESRGAN, (3) remove the background. Demonstrate that chaining models produces a better result than a single generation step.

The Problem

A startup tries to generate product photos using a single model. They prompt FLUX, get a decent image, and ship it. But the background is wrong, the resolution is too low for print, and the brand colors are off. They try a better prompt. Same issues. They switch to Midjourney. Better aesthetics, but still no background removal, no upscaling, no consistency.

The problem isn't the model. The problem is the approach. No single model produces a production-ready asset. Production quality requires chaining multiple models — each handling one stage of the pipeline.

What you'll build
A 3-step workflow using fal.ai: generate an image with FLUX, upscale with Real-ESRGAN, and remove the background. You'll see firsthand why chaining models produces results that single-model prompting cannot.
