1. Quantization Metrics & Quality Comparison

Size & Quality Metrics

Edition / Quantization	File Size	Memory Footprint (Weights)	Total Audited Tensors
BF16 Base (Liquid AI)	47.96 GB	44.67 GiB	428
APEX-I-MiniPlus V2.1 (This Release)	9.64 GB	8.98 GiB	428
APEX-I-NanoPlus	8.15 GB	7.59 GiB	428

[!NOTE] Independent Hardware & Compute Transparency: Generating multi-million token calibration matrices and running certified quantizations on 24B architectures requires dedicated high-end cloud nodes funded 100% out-of-pocket. If you rely on these MiniPlus/NanoPlus builds for your local workloads, contributions to the IsValorum Compute Fund on Ko-fi directly sponsor the GPU/CPU hours required for future Day-0 handcrafted quantizations.

2. Official Liquid AI Benchmarks

LFM2.5-24B-A2B is a 24B parameter reasoning model with only 2B active parameters per token, outperforming larger dense and sparse alternatives across agentic, coding, and mathematical evaluations while running up to 1.7x faster on edge devices:

Key Empirical Strengths:

Autonomous Tool-Use & Function Calling: Reaches state-of-the-art results on LiveClaw (48.09 vs 38.19 on Qwen3.6-35B-A3B) and BFCL v4.
Constant Latency Linear ConvNet Backbone: 30 of the 40 layers utilize 1D short convolutions with O(1) state caching, resulting in blistering inference speeds and near-zero TTFT overhead.
Periodic Attention Anchor: 10 full attention layers distributed every 4 blocks retain long-horizon coherence up to 128,000 tokens.

7. Community Compute Fund & Student Support

All IsValorum quantizations will always remain completely free and open to the public without paywalls.

However, cloud GPU and CPU-performance compute is expensive and funded entirely out-of-pocket. If you find these handcrafted builds to be of high quality and they benefit your day-to-day workflow, you can support future Day-0 releases on Ko-fi. Every contribution directly funds the cloud compute hours required for new model runs and helps support my university education:

(When supporting on Ko-fi, feel free to leave a note with your Hugging Face handle and the specific model you would like prioritized).
