Navigating the APEX-I and VAL-APEX Quantization Ecosystem on Hugging Face
As the catalog approaches 400,000 total downloads across 69 releases, all models are now structured into dedicated official collections on Hugging Face.
Our goal remains consistent: eliminate the compromise between memory overflow and cognitive collapse on consumer hardware (especially 16 GB VRAM GPUs like the RTX 4080, RTX 4070 Ti Super, and RX 7800 XT).
Instead of uniform block quantization, all APEX builds use per-tensor mixed precision guided by 4-moment Importance Matrix statistics:
- MiniPlus Tier (approx. 14 to 14.8 GiB): Strict 0% 2-bit policy. All MoE routed experts locked at minimum IQ3_XXS with Q4_K/Q6_K attention. Designed for 24 GB setups or 16 GB setups with moderate context.
- NanoPlus Tier (approx. 11.5 to 12.3 GiB): Strategic use of IQ2_S/IQ2_XXS exclusively in core feedforward blocks, keeping routers and attention high-precision. Leaves ample VRAM for 16k-32k context on 16 GB GPUs.
Explore the active collections:
- MoE Standard (MiniPlus & NanoPlus): IsValorum/apex-i-miniplus-v21-standard-moe-6acfee77961c8c0cf5a083b5
- MoE Abliterated (MiniPlus & NanoPlus): IsValorum/apex-i-miniplus-v21-abliterated-moe-6acfee762fc4a8cf2298c55b
- 27B Dense Hybrids: IsValorum/val-apex-miniplus-standard-27b-6acfec54ca4ce4cf5cd5bdb6
- Apple Silicon (MLX): IsValorum/mlx-apex-abliterated-6abedb1f9d400e984efe4fc6
