I host 25+ free APEX MoE quantizations as independent research. My only local hardware is an NVIDIA DGX Spark (122 GB unified memory), enough for ~30-50B-class MoEs, but bigger ones (200B+) require rented compute on H100/H200/Blackwell, typically $20-100 per quant.
If APEX quants are useful to you, your support directly funds those bigger runs.

What is APEX?

APEX is a quantization strategy for Mixture-of-Experts (MoE) models. It classifies tensors by role (routed expert, shared expert, attention) and applies a layer-wise precision gradient -- edge layers get higher precision, middle layers get more aggressive compression. I-variants use diverse imatrix calibration (chat, code, reasoning, tool-calling, agentic traces, Wikipedia).

See the APEX project for full details, technical report, and scripts.

Architecture

Model: GLM-4.7-Flash (Glm4MoeLite)
Layers: 47 (1 dense + 46 MoE)
Experts: 64 routed + 1 shared (4 active per token)
Total Parameters: ~30B
Attention: Multi-head Latent Attention (MLA, DeepSeek-V2 style)
APEX Config: 5+5 symmetric edge gradient across 47 layers, MLA-aware tensor mapping
