The node graph the rest of the field is measured against
ComfyUI is an open-source node-based interface for diffusion models
Why: If you want to know exactly what happened between the prompt and the image, this is the tool that shows you. Every step is a node you can open, change and re-run, and a workflow someone else built arrives as a file you can load rather than a screenshot you have to reverse engineer. That reproducibility is why it became the format the rest of the field builds around.

Thinking Machines' 975B Apache-2.0 model that takes text, images and audio natively
Inkling is the first open-weights model from Thinking Machines Lab, released 15 July 2026 under Apache 2
Why: It is the first roughly trillion-parameter open-weights model that takes audio and images natively rather than through a bolted-on encoder, and Apache 2.0 means the weights can be used commercially without asking anyone. Thinking Machines is candid that this is not the strongest model available but a base worth customising, which is a more honest pitch than most open releases make.
