## Useful for

- Generate a 4K image from a text prompt via the CLI
- Edit an existing photo by adding or replacing objects
- Control object placement in an image using bounding boxes

## Why it’s here

- Star-counter measurements on 2026-10-18 (UTC), 00:23–11:49: 89 → 96 stars (+7). This is the change over that interval.
- Estimated end-of-day forecast: about +14 stars, using observed gains and the previous day.
- The repository is 3 days old and already has 96 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Hacker News: “Flux 3 Image Klein” — 7 points, 2 days ago.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 4
- Issues and pull requests: 6
- Watchers: 0
- Average over the last week: 26 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 1

## Stars per day, last 4 days (oldest → newest, today is partial)

2026-10-15 … 2026-10-18: 46, 34, 12, 7

## Magnitude by day, last 2 days

10-17 4.1, 10-18 2.4

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
