Replace the 2-slot ping-pong + single global "compute-started" event
with a depth-N ring buffer where each transfer waits only on the slot
it's reusing (D layers back) instead of the most-recent compute. Applies
to forward and backward, Linear and Conv. Depth is tunable via
AI_TOOLKIT_OFFLOAD_DEPTH (default 4).
Bit-exact vs non-offload (output, grad_input, weight grads). No speedup
on a bandwidth-bound PCIe link (already saturated at depth 2), but the
cleaner per-slot design removes the fragile shared-event serialization
and lets deeper prefetch help on faster buses.
* Initial support for hidream. Lora keys likely need work
* Fix saving for hidream-o1
* Remove dependence on flash attention for hidream o1
* Fix gradient checkpointing for hidream o1
* A lot of fixes for hidream. Handle loading and saving as comfy model.
* Omit layers not used in comfy. Fix issue with lora loading keys in comfy
* Version bumpo
* Base ace step 1.5 xl added. Generating, still wip on training and ui
* Base training code done
* Fix some issues with caching text embeddings. Update sample cards to show audio
* Fix issue with quantizing ace step
* Add album artwork to samples with waveform.
* Cleanup logs
* Add album art endpoint to speed up album art loading
* Made an make video with artwork script
* Make ui handle basic audio models. Make multi line adjustments to the editor and better syntax hilighting.
* Add prompt tagging system for special tagged models.
* prompt tagging processing for ui working.
* Moved default samples to a special file so we can add more when needed and they can be adjusted for a specific model
* Add a captioner job with music captioner that is prepped for use with the ui
* Add basit ui setup for captioning modal and handeling captioning jobs
* Starting captioning job from ui working. Still better management for it.
* Better filtering of job options in the job view for captioning jobs
* Added qwen3 vl as a captioner for images
* Have an indicator when a dataset is being captioned.
* Adjust the way caption jobs look in the queue
* Fix a few issues. Adjust defaults.
* Version bump
* Added ace step to the readme.
* Made an install script and auto updates env for mac
* GPU sensors and initial training working for MAC. Still WIP.
* Switch dataloader to single threaded until I can work around some mac pickeling issues.
* Get quantization working on mac
* Fix mac exclusive imports so they don't break other builds.
* Add mac instructions to the UI
