Hedra says its AMD tuning cuts Krea 3 image edits to 3.6 seconds Hedra said it cut 2K image edits with Krea 3 to 3.6 seconds on AMD Instinct MI355X accelerators, down from about 22 seconds on the same hardware, after rebuilding its inference stack with custom ROCm kernels and lower-precision math. The San Francisco startup added Krea 3, a reference-driven image generation and editing model, to its platform on October 15th and announced the roughly sixfold speedup in a six-post thread on X. Hedra is pitching the AMD inference optimizations as part of its infrastructure offer for serving third-party models, and the speed claim remains company-reported.

The sixfold speed claim remains company-reported. Hedra added Krea 3, a reference-driven image generation and editing model, to its platform on October 15th. In a six-post thread on X https://x.com/hedra labs/status/2110763001372708992?s=46 , the startup said it can return a 2K edit in 3.6 seconds on AMD Instinct MI355X accelerators, down from about 22 seconds on the same hardware before it rebuilt its inference stack.
