+Quality - 10Eros_v1.4_DMD_TFO_Int8-Int8mm_Q 17.5 GB is 50/50 int8/w4a4-int8mm. 20 second gens ok seems to hold up pretty well.
+
+Balanced -10Eros_v1.4_DMD_TFO_Int8-Int8mm_B  14.9 GB is 20/80 int8/w4a4-int8mm. 20 second gens ok, might be better off sticking to 10-15 seconds
+
+Full - 10Eros_v1.4_DMD_TFO_w4a4-Int8mm_F 13.2 GB is 0/100 int8/w4a4-int8mm. Does 5 second gens ok, starts to fall apart pretty quickly after that.

+Made possible by Tsolfils brilliant node https://github.com/tsolful/ComfyUI-INT8-Fast a modification of Bob’s node.
+
+I spent a while going down a rabbit hole splicing int4/int8/bf16 combos in a modified version of comfy-quants, trying to figure out what works before finding Tsolfils node.  I’m pleased I was heading in the right direction but his node is probably much better than what I was going to do.
+ 
+Testing has been unscientific and done in fits and bursts so keep that caveat in mind.
+
+It seems any amount of true w4a4 tensors on their own will taint ltx/eros/sulphur.  You get swimming textures on any length/size generation.  So that's a no go. But packing them in int8mm seems to fix that problem.
+
+At first I thought the hard limit was a 50/50 combo of int8 and w4a4 int8 matmul, but once I stopped letting true w4a4 filter into the mix I was able to make a 20/80 mix and 100% w4a4 int8-matmul with no more texture swimming artifacts or vastly diminished at any rate.
+
+Quality - 10Eros_v1.4_DMD_TFO_Int8-Int8mm_Q.safetensor sits below fp8 in my opinion but that's subjective and I have no LPIPS data to back that up.
