BLEH

ComfyUI nodes collection... eventually.

Features

Currently only better TAESD previews.

Copy blehconfig.json.example to blehconfig.json in the node repo directory and edit the copy.

Restart ComfyUI to apply new changes.

Supports setting max preview size (ComfyUI default is hardcoded to 512 max).
Supports showing previews for more than the first latent in the batch.
Supports throttling previews. Do you really need your expensive TAESD preview to get updated 3 times a second?
Supports using CUDA streams to avoid waiting for a synchronize. This might be faster.

Current defaults from blehconfig.json

Key	Default	Description
`enabled`	`true`	Toggles whether enhanced TAESD previews are enabled
`max_size`	`768`	Max width or height for previews. Note this does not affect TAESD decoding, just the preview image
`max_batch`	`4`	Max number of latents in a batch to preview
`max_batch_cols`	`2`	Max number of columns to use when previewing batches
`throttle_secs`	`1`	Max frequency to decode the latents for previewing. `0.25` would be every 1/4 sec, `2` would be only once every two seconds
`use_cuda`	`true`	Use special logic for CUDA (and maybe pretend-CUDA like ROCM) to reduce the performance impact of preview generation

I would recommend setting throttle_secs to something relatively high like 5-10 sec especially if you are generating batches at high resolution.
