Quantized, converted, and evaluated by [PBH Applied Systems, LLC](https://pbhappliedsystems.com) — 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 v7.22.21/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.

✓ No statistically significant degradation from F16 in any family (McNemar p < 0.05: 0 of 8). Stateful execution (1.000), hybrid responses (1.000), and end-to-end tool calls (0.930) match F16 case for case; schema-only tool calls differ by a single case (0.995 vs 1.000). Q8_0 is the conservative quantization: it preserves measured behavior in exchange for more modest footprint and speed gains.

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 · 3 example queries per agent type · 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 Example queries: Should a startup build on cloud LLMs or self-host quantized models? · Analyze the trade-offs between model quantization and inference latency. · What are the cost implications of running 14B parameter models on edge devices?

• —Document Intelligence — Long-context information extraction and Q&A Example queries: Extract key clauses from a contract and summarize legal risks. · Analyze a research paper and identify the novel contributions. · Compare market analysis reports and highlight strategic differences.

• —Code & Automation — API scaffolding, data transformation, and task completion Example queries: Build a REST API endpoint for user authentication and include rate limiting. · Transform CSV data into a production-ready database schema. · Write a Python script to validate and clean messy customer records.

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 Agent Arena lets you:

• —Select any two evaluated models (F16 or quantized variants) and test them side-by-side on the same queries
• —View execution traces for both agents, showing chain-of-thought reasoning and tool dispatch
• —Check the Model Leaderboard — a ranked table of all evaluated models with scores across four behavioral dimensions: Task Completion, Reasoning, Coherence, Instruction Following
• —Read the Methodology tab — explanation of quant_eval, the 8 test families, and how to request a full evaluation report for models not yet in the series

Why compare in the Arena:

The demo shows what this model can do. The Arena shows how this model compares to others. If you're deciding between F16 and Q5KM, or between this model and another in the series, run the same query in the Arena with both selected. You'll see the exact differences in reasoning quality, tool dispatch, and output coherence — not benchmark scores, but real agent behavior.

Evaluation-backed leaderboard: Every score in the Arena comes from quant_eval runs published to Zenodo (DOI `10.5281/zenodo.22009419`). The numbers are not opinionated; they're measured.

Model Description

This repository contains the 8-bit quantized (Q8\_0) GGUF of `mistralai/Mistral-Nemo-Instruct-2407`, a 12-billion parameter instruction-tuned model developed by Mistral AI in collaboration with NVIDIA (July 2024 release). Mistral-Nemo features the Tekken tokenizer and a 128,000-token context window — the largest in the PBH Applied Systems evaluated series outside of Qwen2.5-14B-Instruct-1M, which supports a 1 million token window.

The Q8\0 format applies 8-bit quantization. Unlike Q4\K\M, which introduces significant behavioral tradeoffs, Q8\0 matches F16 case for case on stateful execution, end-to-end tool dispatch, and hybrid responses — families central to agentic AI workflows. This is the quantization to choose when behavioral fidelity and model reliability are the top priorities, with efficiency gains as a secondary benefit.

The full-precision F16 baseline is published separately at `pbhappliedsystems/mistral-nemo-instruct-2407-gguf-F16`.

Evaluation Contract: canonical_agentic_contract_v7.22.18:evaluation

Direct comparability: Q80, Q5KM, and Q4KM were all evaluated on identical fixtures against the same F16 baseline. Q80 and Q5KM both show no statistically significant degradation; Q5KM is faster (2.65× vs 1.78× same-run generation throughput) and smaller, while Q8_0 is the more conservative choice.

Comparability & Fixture Methodology

Identical Fixtures Across All Three Runs

All three Mistral-Nemo runs were evaluated against the same 1,600 cases. A full structural comparison of the fixture files across bundles shows the only differing key is the top-level version label: all cases, oracle expectations, and trace_sha256 values are identical, and fixture_schema_version is 7.22.13 in every bundle.

Baseline reproducibility: The F16 baseline was executed in all three runs, on different days and under both contract revisions. All eight family pass rates are identical across the three runs, and at case level 0 of 1,600 cases differ in any pairwise comparison. The Q4KM, Q5KM, and Q8_0 deltas are all measured against the same baseline.

The Zenodo datasets record the fixture version-label crosswalk (D3) and per-run manifests (D4) for full reproducibility.

Per-Family Paired Comparison — F16 Baseline vs. Q8\_0

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

\* mcq pass rates are identical, but two cases are discordant (one F16-only pass, one Q8_0-only pass). The other five "PERFECT MATCH" families are identical case for case.

Sources:

• —quant_eval Family Pass Rates, DOI `10.5281/zenodo.22010623`
• —quant_eval Paired Degradation Statistics, DOI `10.5281/zenodo.22010557`

Key Findings

Finding 1: Six Families — Identical F16 Pass Rates

Q8_0 matches F16's pass rate on six of eight families (five identical case for case; `mcq` has one discordant case in each direction):

Why it matters: Q8_0 matches F16 case for case on stateful, hybrid, and end-to-end tool-calling families, and matches F16's pass rates on all structured-output families. No family shows a statistically significant behavioral cost. This is the quantization to choose when reliability and model fidelity are the priority.

Implication: Deploy Q80 as you would deploy F16 — with the same validation F16 itself requires, and none of the additional guardrails Q4K_M needs.

Finding 2: Negligible Loss on Two Families

Two families show minor, statistically non-significant differences:

Why it matters: The McNemar p-values (1.000) indicate these differences are noise, not signal. One case in toolcall_only failed under Q8_0 where F16 succeeded — a data point, not a trend. Fuzz actually shows a tiny gain, well within variance.

Implication: Operationally equivalent to F16 on all eight families.

Finding 3: Conservative Quantization — The Right Choice for High-Stakes Deployments

Q8_0 is the quantization for:

• —Production agents where failures are costly
• —Workflows where reliability >> speed
• —Teams without advanced fallback/retry infrastructure
• —Models deployed to constrained but capable hardware (~15 GB VRAM available)

The 1.78× same-run generation throughput (vs F16) and 47% footprint reduction are real. No statistically significant behavioral loss is the gain that matters.

Efficiency & Footprint

Source: quant_eval Efficiency & Footprint, DOI `10.5281/zenodo.22010723`

Q8_0 trades maximum efficiency for maximum reliability. The speedup and footprint reduction are meaningful but not extreme. This is the quantization when the goal is "get better hardware utilization without breaking the model."

Quantization Variants Comparison

See how this model performs across all three quantized variants. All three were evaluated on identical fixtures against the same F16 baseline.

How to read this table: Speed is the observed evaluation wall-time ratio (F16 ÷ quantized) on matched RTX 4090 hardware — not a controlled throughput benchmark. Stateful/Toolcall-only/Hybrid are pass rates.

See the full cards:

• —`F16` — Baseline reference
• —`Q4_K_M` — Extreme compression, significant behavioral cost
• —`Q5_K_M` — Balanced quantization, best efficiency/reliability ratio

Artifact Provenance

Both artifacts were produced from mistralai/Mistral-Nemo-Instruct-2407 using a custom-built llama.cpp conversion and quantization pipeline developed by PBH Applied Systems.

Deployment Recommendations

✅ Deploy Q8_0 when:

• —Behavioral reliability is the priority. Six families match F16's pass rate; no family shows a statistically significant difference.
• —You can afford ~15 GB VRAM. Q8_0 fits on 16 GB-class GPUs and larger (A10G, RTX 4090, A100 40GB).
• —Simplicity matters. Deploy as you would F16 — no additional retry or fallback logic beyond what F16 itself requires.
• —Your workflow uses stateful conversations. Perfect performance on stateful_followup (1.000).
• —Tool calling must match F16. End-to-end toolcall is 0.930 — identical to F16, case for case.
• —You want the lowest measured quantization risk. Q8_0 shows the smallest deviation from F16 of the three variants evaluated.

⚠️ Avoid Q8_0 if:

• —Extreme efficiency is the goal. Q5KM is faster (2.56× vs 1.71× observed wall-time ratio vs F16) and smaller (8.73 GB vs 13.0 GB); Q4KM is the smallest (7.48 GB).
• —You need maximum speed at acceptable reliability. Q5KM is the better choice — faster, with no statistically significant degradation in any family.
• —Hardware is extremely constrained. Q4KM fits in ~10 GB; Q8_0 requires ~15 GB.

🎯 Recommended Deployment:

Q8_0 is the reliability-first quantization. Use it for:

• —Production agents with high uptime / low-tolerance-for-failure requirements
• —Regulated environments requiring documented model behavior preservation
• —Teams prioritizing operational simplicity over extreme efficiency
• —Scenarios where one agent failure blocks critical workflows

Q5KM requires less VRAM (~11 GB vs ~15 GB) and offers better efficiency, also without statistically significant degradation. Q8_0 is the choice when you want the smallest measured deviation from F16.
