This event is about generating images with AI. There's no single model we're locked into, the point is to explore what's out there and actually try a few. We'll focus on open-source models, but you're welcome to bring commercial ones (DALL·E, Midjourney, and friends) if you want to compare.

Drop a comment with ideas for future topics (agents, RAG, MLOps, robotics, frameworks, and more).

We'll try to look at both major families: diffusion-based models (the dominant approach today) and transformer-based / autoregressive image models. I'll research and try some of the best open-source options ahead of the stream, and if time allows we'll also try fine-tuning with LoRA to teach a model a new style or subject.

Some things to look up to get started:

Open-source models:

FLUX.2 (Black Forest Labs): current open-weight quality benchmark; DiT backbone, up to 4MP, multi-image reference
Stable Diffusion 3.5 / SDXL (Stability AI): deepest ecosystem — LoRA, ControlNet, inpainting, countless fine-tunes
Qwen-Image (Alibaba): strong all-rounder, especially good at rendering text (including Chinese)
Z-Image / Z-Image-Turbo: Apache-2.0, near FLUX.2 quality in just a few steps (fast and commercial-friendly)
HunyuanImage (Tencent): another high-quality open-weight option
Tooling:

Try spending 30–90 minutes during the week learning or building something related to the topic, then share what you’re working on in Slack.

Note on Flyte / Union
You may see Flyte used in some demos. Flyte is an open-source AI orchestration platform maintained by Union (where I work) for building scalable, durable, and observable AI workflows. You do not need to use Flyte to participate.
