Xing4.0 Guide: VRAM Requirements, GGUF Builds

September 28, 2026

Everything Local Model Watch has published about the Xing4.0 family: 1 article(s) covering the base model and its fine-tunes, plus converted builds we tracked after publication. Memory requirements below are computed by this site from file sizes, not quoted from model cards. Part of our model family index.

At a Glance

Hardware Requirements

Estimated requirements (calculated by Local Model Watch) — 31.2B parameters

Memory estimates add a 20% runtime overhead (KV cache, etc.) to the actual size of the distributed files. Actual usage varies with context length, batch size and inference engine. These figures are computed by this site from file sizes, not published by the model’s authors. File sizes are measured from the converted build XingChen-AGI/Xing4.0-29B-A4B-GGUF. Compare with other models in our VRAM quick reference. What the quantization names mean: glossary.

Can You Run It Locally?

Runs in Ollama, LM Studio and llama.cpp via a converted build.

The publisher ships safetensors, but XingChen-AGI/Xing4.0-29B-A4B-GGUF provides a GGUF build you can use.

License — apache-2.0 (Commercial use allowed): Permits commercial use, modification and redistribution. Redistribution requires including the license and stating changes; includes a patent grant.

Compression: the IQ4_NL build measures 5.15 bits per weight — about 32% the size of the original 16-bit weights, calculated by this site from the actual file sizes.

Compiled by this site’s code from the published formats, converted builds we have found, and each engine’s own model registry. “Not found" means we have not seen such a build, not that none exists. License summaries are not legal advice — check the publisher’s original terms before relying on them.

Quantized and Converted Variants

File sizes of each build:

• Available builds in XingChen-AGI/Xing4.0-29B-A4B-GGUF: IQ4_NL 18.7GB
• Available builds in XingChen-AGI/Xing4.0-29B-A4B-FP8: FP8 30.9GB
• Available builds in mlx-community/Xing4.0-29B-A4B-OptiQ-4bit: MLX 4bit 19.2GB

This section is appended automatically by Local Model Watch when a converted build of this model appears after publication. Memory figures are estimated from the size of the distributed files.
