Fix dtype issue with hidream o1 (#13849) 2026-05-11 20:53:13 -07:00

feat: Support HiDream-O1-Image (CORE-187) (#13817)
* Initial HiDream01-image support

* Cleanup nodes

* Cleaner handling of empty placeholder models

* Remove snap_to_predefined, prefer tooltip for the trained resolutions

* Add model and block wrappers

* Fix shift tooltip

* Add node to work around the patch tile issue

Experimental, runs multiple passes with the patch grid offset and blends with various different methods.

* Qwen35 vision rotary_pos_emb cast fix

* Fix embedding layout type

* Some small optimizations

* Cleanup, don't need this fallback

* Prefix KV cache, cleanup

Bit of speed, reduce redundant code

* Get rid of redundant custom sampler, refactor noise scaling

Our existing lcm sampler is mathematically same, just added the missing options to it instead and a node to control them. Refactored the noise scaling and fix it for the stochastic samplers, add a generic node to control the initial noise scale.

* Update nodes_hidream_o1.py

* Fix some cache validation cases

* Keep existing sampling params

* Remove redundant video vision path

* Replace some numpy ops with torch

* Fx RoPE index for batch size > 1

* Prefer torch preprocessing

* Rename block_type to be compatible with existing patch nodes

* Fixes and tweaks

feat: Gemma4 text generation support (CORE-30) (#13376)
* initial gemma4 support

* parity with reference implementation

outputs can 100% match transformers with same sdpa flags, checkpoint this and then optimize

* Cleanup, video fixes

* cleanup, enable fused rms norm by default

* update comment

* Cleanup

* Update sd.py

* Various fixes

* Add fp8 scaled embedding support

* small fixes

* Translate think tokens

* Fix image encoder attention mask type

So it works with basic attention

* Handle thinking tokens different only for Gemma4

* Code cleanup

* Update nodes_textgen.py

* Use embed scale class instead of buffer

Slight difference to HF, but technically more accurate and simpler code

* Default to fused rms_norm

* Update gemma4.py
