The Krita plugin is a bridge to ComfyUI which can already run Flux and presumably will have native support for Kontext (dev) within a week or so, and the plugin already has limited support for using Flux, so Kontext in the existing plugin (rather than requiring a new one) seems a fairly reasonable expectation.

This was pessimistic, native support today, with workflow and pointer to an alternate fp8 model download for people that can't run the full fp16 checkpoint.
