Best Use Cases
Ehsan's Growth Take
Flux is what happens when the people who built Stable Diffusion start over with everything they learned. The quality-to-cost ratio is unbeatable if you have the technical chops to deploy it. Growth teams with even one ML-curious engineer should be running Flux Pro through Replicate instead of paying Midjourney per-seat.
