H3 results are underwhelming compared to LTX 2.3 so far:

Perhaps refined ComfyUI workflows will squeeze more quality out of it, but it's definitely not in the realm of Seedance, and Lightricks is training LTX 2.5/"LTX-Next".
Note: Those results are a little misleading the good LTX results were generated with a good workflow in ComfyUI, and a prompt expanding local model.
Whilst the H3 result was generated with the raw api using his raw prompt.
If you ask ChatGPT or other AI model to "improve" your prompt (with cinematic, good lighting) generally, you will get also very good result from H3 also.
My own H3 test show that H3 (API edition) is undoubtedly better than LTX in prompt adherence ! The real comparison will be with the edition of H3 we get to run locally.
