 - **2026-08** **EXL3 checkpoints now generate on CPU and CUDA.** A stock
   Llama-3.2-1B-Instruct EXL3 checkpoint loads through the shared dense model path and emits text.
   The current CUDA path supports its 3-bit body and 6-bit output head. No speed claim is available.
-- **2026-08** **GGUF gains IQ2_XS and IQ4_XS.** Both formats decode and run directly on their
-  compressed blocks on CPU. This lets the 101.25 GiB GLM-5.3-Flash GGUF weight tower load without
-  expanding to 426.72 GiB. Its model forward is still incomplete.
+- **2026-08** **GLM-5.3-Flash now generates on CPU from a 101.25 GiB GGUF.** The shipped
+  `UD-Q2_K_XL` artifact emits coherent text while keeping IQ2_XS and IQ4_XS blocks compressed.
+  Both formats also have CUDA keep-quant kernels, but this model's CUDA forward and every speed
+  gate remain pending.
+- **2026-08** **GLM-5.3 joins the model registry.** Its GGUF loader and first-token forward run
+  through the shared expert-streaming path. The real 201.83 GiB artifact has not completed a load,
+  and resumed sparse decoding still needs the indexer side cache, so no real-checkpoint token or

 - **2026-08** **Hybrid CPU/GPU expert placement reaches five architecture families.** Qwen3-MoE,
   Qwen3.5/3.6, Nemotron-H, DeepSeek-V2, and Kimi-Linear can run routed experts on the CPU while the
   rest of the model stays on the selected accelerator. The end-to-end token and speed gates are
