This is the complete TrellisMX codec-v2 checkpoint package, variant B, built on four rented NVIDIA B200 GPUs. The root contains all 42 main routed layers plus MTP45 in 172 TP4 sidecars in the existing coupled H512/H128 format. carrier/ contains the unchanged backbone, shared-expert, attention, vision, non-expert MTP, scale, configuration, and tokenizer assets from the pinned native carrier. No separate base-weight download is required. Loading requires the TrellisMX runtime; this is not a generic Transformers checkpoint. Download the complete package with hf download brandonmusic/glm-5.3-flash-tr3-fp8 --local-dir glm-5.3-flash-tr3-fp8. The root config.json is included in the complete…

Compare the published evidence
This profile connects the 2 model and dataset records shown below to their upstream cards and sources. The library counts describe SAVRN's coverage, rather than this publisher's entire output.
Published tasks: Image and text to text.
Reported licenses: other. Open a record to review its specific license and conditions.
Compare model specifications, source dates, and hardware estimates on the individual records. Publisher identity verification is separate from a model's quality, deployment readiness, or suitability for your work.

A lossless repack of stepfun-ai/Step-5-Preview-NVFP4 (revision bc246cc2848e17b37f377eda8fd825c5b3018d1f), 17.1 GB smaller. The NVFP4 block scales of the routed experts are stored in b12x's compressed scale format (CSF), the lossless format introduced with nvidia/Qwen3.8-Flash-Next-FP4-Local. Every FP4 weight byte and every other tensor is identical to StepFun's checkpoint, and every scale decodes to StepFun's exact bytes, so this checkpoint computes exactly what Step-5-Preview-NVFP4 computes. Step 5 Preview is StepFun AI's model: a sparse mixture of experts with 600B total and 27B active parameters, text and image input, up to 1M tokens of context. Model card: stepfun-ai/Step-5-Preview.…
