Ministral-3-14B-Instruct-2512 · GGUF Q4_K_M

Quantized, converted, and evaluated by PBH Applied Systems, LLC — Applied AI/ML Consulting · LLM Optimization & Deployment · Quantized AI Infrastructure

🔬 This repository is part of a production-oriented evaluation series. Every model published under pbhappliedsystems has been independently evaluated using quant_eval v7.22.22 — a behavioral evaluation harness developed by PBH Applied Systems. Scores measure real agent-adjacent task performance across structured output, tool dispatch, multi-turn state retention, and multi-step planning families — not perplexity or benchmark leaderboard proxies.

⚠️ Behavioral degradation from BF16 to Q4_K_M is statistically significant in 1 of 8 families (McNemar p < 0.05): mixed_brief_json (−0.075). The evaluation data below specifies which tasks need guardrails or a higher precision.

Try the Live AI Agent Demo & Compare Models

Two complementary interfaces, both free:

1. Quick Demo — Single Model Testing

Launch the PBH Applied Systems AI Agent Demo →

Free · No account required · No document upload

Test this model (or others) against three agent workflow templates:

• Reasoning & Analysis — Chain-of-thought decomposition and structured problem-solving
• Document Intelligence — Long-context information extraction and Q&A
• Code & Automation — API scaffolding, data transformation, and task completion

Every query runs on private GPU infrastructure — your prompts, reasoning traces, and outputs never leave the system and are never sent to Frontier model providers or cloud vendors. This matters for organizations with sensitive data, compliance requirements, or internal knowledge that cannot leave the building.

2. Model Comparison Arena — Side-by-Side Evaluation

Launch the quant_eval Agent Arena Space →

Compare two models in real-time across all three agent types.

The demo shows what this model can do. The Arena shows how this model compares to others. If you're deciding between BF16 and a quantized build, or between this model and another in the series, run the same query in the Arena with both selected.

Evaluation-backed results: every score shown for this model comes from its sealed quant_eval run bundles; the full results page is pbhappliedsystems.com/models/ministral-3-14b-instruct-2512.

Comparability & Fixture Methodology

Identical Fixtures Across All Three Runs

Baseline reproducibility: The BF16 baseline was executed in all 3 runs. All eight family pass rates are identical across the runs, and at case level 0 of 1,600 cases differ in any pairwise comparison. Every quantized delta is measured against the BF16 lane of its own run.

---

Per-Family Paired Comparison — BF16 Baseline vs. Q4_K_M

All rates include 95% Wilson score confidence intervals. McNemar p-values test statistical significance of paired differences. N = 200 cases per family.

Source: sealed quant_eval run bundles; full tables at pbhappliedsystems.com/models/ministral-3-14b-instruct-2512

---

Key Findings

Finding 1: mixed_brief_json — significant loss (−0.075)

What fails: 17 of 200 Q4_K_M cases fail where BF16 succeeds (semantic_payload_ok false in 17); 2 cases pass only at Q4_K_M.

Mitigation: see mixed_brief_json mitigations (engineering advice, not measured in this run), or use a precision that holds this family: Q5_K_M, Q8_0, BF16.

Finding 2: Largest movement without significance — json (+0.010)

The 95% interval [−0.048, 0.068] includes zero and McNemar p = 0.7744: 5 cases pass only at BF16, 7 only at Q4_K_M. Within measurement noise at n = 200.

Efficiency & Footprint

Hardware: both lanes executed on NVIDIA A100-40GB; ratio is a precision comparison.

Quantization Variants Comparison

See how this model performs across all three quantized variants. All three were evaluated on identical fixtures against the same BF16 baseline.

How to read this table: Speed is the observed evaluation wall-time ratio (BF16 ÷ quantized) on matched A100-40GB hardware — not a controlled throughput benchmark. Stateful/Toolcall-only/Hybrid are pass rates.

• BF16

• Total unique cases: 1,600 (200 per family × 8 families)

Evaluation hardware: NVIDIA A100-40GB
Runner: quantized_modal_llama_cpp (llama.cpp via Python binding on Modal)
Decoding: temperature 0.15, seed 42, top_p 0.95, top_k 40
Context: 8,192-token context window (llama.cpp configuration)
Reproducibility: sealed run bundles (checksums above); per-case results on request

Deployment Recommendations

✅ Deploy Q4_K_M when:

• Footprint is the constraint. 8.24 GB against 27.02 GB for BF16.
• Your agent does not depend on mixed_brief_json. No significant change in json, json_multistep, stateful_followup, mcq, toolcall, toolcall_only, fuzz.

⚠️ Avoid Q4_K_M if:

• mixed_brief_json is central to your workflow. It loses 7.5 points against BF16.

🔄 Alternative:

Q5_K_M or Q8_0 showed no statistically significant change in any family at 9.62 GB / 14.36 GB.
