AI fashion assistants. UI variants of your favorite websites. Voice-assisted photo editors. 3D dinner tables. Text-to-movie apps.

Our FLUX.1 Kontext hackathon might’ve been our best one yet. We teamed up with Black Forest Labs to give over 120 participants the chance to build with FLUX.1 Kontext, the image editing model that has taken the AI community by storm. Resemble AI also joined us to get hackers to build with Chatterbox, their latest text-to-speech model.

We had some insanely creative projects and we were thoroughly impressed by what people built in a couple hours. Choosing from 30 submissions wasn’t easy, but a few stood out to us.

Here were the winners.

Replicate’s picks:

• Tartan Photographers: AI-automated Shopify listings

  Rafael Cabrera and Christian Cherry created a site which automates uploading listings on Shopify and even edits your product photos with FLUX.1 Kontext to make them click-enticing. We last saw this power team at our Carnegie Mellon University hackathon, and we’re super glad they were able to build with Replicate again!

• The Table: Conjure food on a 3D dinner table

  This was a fun little project by David Tian. Users enter a food item and a 3D render of it from firtoz/trellis will be placed on a virtual dinner table. We thought this was a neat application of chaining models, super clean UI, fun application of graphics principles: just an overall good hack.

Black Forest Labs’ picks:

• sellmyshit: Upload products to digital marketplaces

  Another great marketplace-integration app from Vibhu Sapra. sellmyshit allows users to create listings on Ebay, Craigslist, and Facebook Marketplace with generated text descriptions and FLUX.1 Kontext image editing. Such a useful tool that takes the drudgery out of making good product listings!

• Infinity: AI Dungeons and Dragons

  Pretty much infinite Dungeons and Dragons, all generated images tossed back and forth to FLUX.1 Kontext. Created by Nihar Asare, this was the selling point: “Play for 5 minutes. 5 hours. 5 days. 5 years.”

Resemble AI’s pick:

• Intel i5-8250U: AI journey generator

  A creative storytelling app made by Fouzan Abdullah and Saad Ahmed that generates personalized adventure narratives using AI. Users input their preferences and the app creates unique journey experiences with custom imagery and descriptions, all powered by FLUX.1 Kontext for visual storytelling and Chatterbox for engaging audio.

Most ‘Vibiest’ Project

We had an extra surprise up our sleeve — Most “Vibeist” Project. These prizes went out to the hacks we thought were just cool, interesting, or flat out “vibey.”

• VoiceCam: Edit photos with your voice

  Before the hackathon, our fellow Replicant Zeke demonstrated to hackers how you can use FLUX.1 Kontext to make a realtime image editing assistant powered by your voice. Hacker Matt Wong took it and ran to create a snappy mobile version that even works with your phone camera. Sick!

• NatureBrawl: AI-powered nature battle simulator

  Bryant Wolf built an imaginative game where users can pit different animals against each other in epic battles. The app uses FLUX.1 Kontext to generate dynamic battle scenes and visual effects, creating unique showdowns between creatures. It also had a crazy good UI.

• FLUX Vibes: Style image transformation app

  A creative app made by Arjun Kaul that transforms photos straight from your camera roll with different styles. We were particularly impressed by the search functionality Arjun developed where users are offered a pruned list of styles to select from based on his or her query.

We were incredibly inspired by the cracked energy. Congrats to all the hackers!

Speaking of hacking, now you can go one layer deeper with FLUX.1 Kontext.

That’s right, Black Forest Labs has released FLUX.1 Kontext dev — open code, open weights. There’s so much you can explore with dev: multi-image or multi-LoRA support, fast inference tricks, playful prompt embeddings in CLIP space, or you could recreate our FLUX.1 Kontext apps closer to the bare metal. There’s endless opportunity to flex your AI engineering muscles. It’s not everyday that we get something open source from Black Forest Labs!

We want to see what you can build. Can you conquer any of those challenges I listed, or solve one of your own?

As always, reach out on our Discord for hacking help and share what you create on X.
