Qwen2.5-14B-Instruct -- jBlaze Q2_K

A behaviorally enhanced Q2_K quantization of Qwen2.5-14B-Instruct, produced by the jBlaze weight-editing framework.

What This Is

A Q2_K quantization of Qwen2.5-14B-Instruct with jBlaze behavioral modifications applied. The result is a 5.4GB model that scored 90/100 on our adversarial evaluation versus 88/100 for the 28GB FP16 original.

Benchmark: 100-Question Adversarial Suite

Model Size Score
Vanilla FP16 28 GB 88/100
Vanilla Q4_K_M 8.4 GB 88/100
Vanilla Q2_K 5.4 GB 88/100
jBlaze Q2_K 5.4 GB 90/100

The test suite covers 9 adversarial categories: cognitive reflection tricks (15), math (15), logic (15), hallucination resistance (10), sycophancy resistance (10), edge cases (10), calibration (10), instruction following (10), and factual knowledge (5).

All four models were tested on identical prompts with deterministic decoding (temperature 0, greedy sampling). Questions are designed to exploit common LLM failure modes -- trick questions, leading premises, mathematical traps, and calibration probes.

Key Finding

Qwen2.5-14B is remarkably resilient to quantization -- vanilla FP16, Q4, and Q2 all score 88/100. The jBlaze Q2_K scores 90/100, preserving -- and on this evaluation slightly improving -- measured performance at 5.2x smaller size.

Usage

This is a standard GGUF file. Use with llama.cpp, ollama, LM Studio, or any GGUF-compatible inference engine:

# llama.cpp example
./llama-cli -m Qwen2.5-14B-Instruct-jBlaze-Q2_K.gguf -p "Your prompt here" -n 512

Framework

  • jBlaze: Precision neural surgery framework for transformer models
  • Method: Behavioral modifications derived analytically -- no training loop, no gradients
  • Quantization: Q2_K via llama.cpp

A Note on Our Released Models

Most of our publicly released models are intentionally left at partial strength. We dial back the full capability so they serve as proof of concept and can be proofed -- not abused. The point is to show what's possible, not to hand it out at full power. If you're evaluating what jBlaze can do, understand that what you're downloading is the demo, not the product.
