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 v7.21 — a proprietary 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.

This model is part of the PBH Applied Systems live AI Agent Demo, where visitors can test evaluated quantized open-weight models across production-style agent workflows: reasoning and analysis, document intelligence, and code automation.

The demo uses quant_eval results to show how model selection changes by task. A model that performs well for long-context document analysis may not be the best choice for hard multi-step planning, strict tool-use workflows, or production code generation. Each deployed model is evaluated for practical agent behavior, including coherence, instruction following, reasoning, task completion, structured output reliability, tool-use behavior, and quantization impact.

For this repository, the Q4_K_M variant represents the deployment-focused model: smaller, faster, and more cost-efficient than the F16 baseline. The evaluation results below explain where this quantized model preserves useful behavior, where quantization introduces risk, and what guardrails are recommended before production deployment.

The purpose of the demo is simple: let prospects test the same kind of evaluated quantized models that PBH Applied Systems deploys for real agentic AI systems.


Model Description

This repository contains the 4-bit quantized (Q4\_K\_M) 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 context in the evaluated series, outside of the Qwen2.5-14B-Instruct-1M, which supports a 1 million token window, in the PBH Applied Systems evaluated series.

The Q4\_K\_M format applies 4-bit quantization with K-quant medium precision. As documented in the evaluation section below, Q4\_K\_M quantization produces measurable degradation on multi-step planning tasks — including a complete breakdown on the hardest planning case — while preserving strong performance on stateful, structured-output, and hybrid response tasks.

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

Key Findings

Finding 1: json\_multistep — Complete Breakdown on Hard Case

The drop from 0.600 (F16) to 0.400 (Q4\_K\_M) is the largest json\_multistep degradation in the PBH Applied Systems evaluated series to date. The case-level breakdown reveals why:

| Case | Difficulty | F16 Result | Q4\_K\_M Result | Q4\_K\_M Signals |

|---|---|---|---|---|

| ms\_easy\_01 | Easy | ✅ PASS | ✅ PASS | All pass |

| ms\_easy\_02 | Easy | ❌ FAIL | ❌ FAIL | cc=0, oe=0 |

| ms\_med\_01 | Medium | ✅ PASS | ✅ PASS | All pass |

| ms\_med\_02 | Medium | ✅ PASS | ❌ FAIL | cc=0 only |

| ms\_hard\_01 | Hard | ❌ FAIL | ❌ FAIL | ALL 4 signals fail |

ms\_hard\_01 at Q4\_K\_M is a total failure: schema_ok=0, checks_consistent_ok=0, stop_semantics_ok=0, oracle_equiv_ok=0. All four Tier-1 gating signals fail simultaneously. The model does not produce a parseable schema response, its intermediate checks are self-inconsistent, its STOP semantics are wrong, and the computed final state does not match the oracle. The F16 variant fails this case too — but only on consistency and oracle, not on schema or STOP semantics. Quantization turns a partial failure into a complete one.

ms\_med\_02 is a new failure at Q4\_K\_M that passes at F16: checks_consistent_ok=0 with oracle_equiv_ok=1 — the model arrives at the correct final state but its internal reasoning steps are self-inconsistent. This is a structural coherence regression under quantization.

Practical implication: This model at Q4\_K\_M should not be used for multi-step planning tasks without an external validation layer. The hard case cannot be considered reliably solvable at this precision level.

Finding 2: toolcall — Final Mismatch on tool\_02 (Q4\_K\_M)

toolcall passes at 1.000 (both stage1 signals pass), but tool_02 shows detail=final_mismatch with bucket_score=0 at Q4\_K\_M. The tool call JSON is dispatched and validated correctly — the stage-1 parse and schema check both pass — but the model's final answer (the computed result returned after tool execution) does not match the expected output.

| Case | F16 bucket | Q4\_K\_M bucket | Q4\_K\_M detail |

|---|---:|---:|---|

| tool\_01 | 11 | 11 | ok |

| tool\_02 | 11 | 0 | final\_mismatch |

This is not a gating failure — the pass rate remains 1.000 because Tier-1 only evaluates the dispatch quality, not the final answer. However, in a production pipeline where tool results feed downstream computation, a final\_mismatch means the model called the tool correctly but gave a wrong answer when reporting the result. For applications where post-tool reasoning accuracy matters, treat this as a deployment risk at Q4\_K\_M.

The Q4\_K\_M toolcall bucket\_score average of 5.5 (vs 11.0 at F16) directly reflects this: one perfect (11) and one complete failure (0) averaged together.

Finding 3: toolcall\_only — Consistent args Failure with Stable Tool Name

| Signal | F16 Rate | Q4\_K\_M Rate |

|---|---:|---:|

| tool\_name\_ok | 1.000 | 1.000 |

| args\_ok | 1.000 | 0.000 |

| schema\_ok | 0.000\* | 0.000 |

At F16, toolcall_only passes gating (tool\_name\_ok=1, args\_ok=1) but carries the same schema wrapper non-compliance observed across multiple models in this series (schema_ok=0, detail=schema_error). At Q4\_K\_M, tool_name_ok stays perfect at 1.000 — the model correctly identifies which tool to call — but args_ok drops to 0.000 on both cases. The quantized model knows the tool name but cannot construct a valid argument payload.

\*F16 schema\_ok=0 is a non-gating wrapper issue (uses "tool" instead of "tool_name" as outer key), not a capability failure. Both gating signals pass at F16.

Finding 4: MCQ "got=A" Bias

Both runners show a systematic bias toward selecting choice A on failures:

| Case | F16 result | Q4\_K\_M result |

|---|---|---|

| mcq\_01 | ✅ ok | ✅ ok |

| mcq\_02 | ❌ wrong\_choice got=A | ❌ wrong\_choice got=A |

| mcq\_03 | ✅ ok | ✅ ok |

| mcq\_04 | ✅ ok | ❌ wrong\_choice got=A |

| mcq\_05 | ❌ wrong\_choice got=A | ❌ wrong\_choice got=A |

Every failure on both runners produces got=A. This is a model-level characteristic: when uncertain, this model defaults to option A. Q4\_K\_M extends this bias to mcq\_04 (which F16 answers correctly), reducing the bucket\_score from 0.600 to 0.400. For MCQ applications, be aware of this A-default tendency and consider instruction-tuning or chain-of-thought prompting to elicit more deliberate choice selection.


Signal-Level Diagnostics (Q4\_K\_M)

json\_multistep

| Signal | F16 Rate | Q4\_K\_M Rate | Delta |

|---|---:|---:|---:|

| schema\_ok | 1.000 | 0.800 | −0.200 |

| checks\_consistent\_ok | 0.800 | 0.400 | −0.400 |

| stop\_semantics\_ok | 1.000 | 0.800 | −0.200 |

| oracle\_equiv\_ok | 0.600 | 0.600 | 0.000 |

| final\_consistent\_ok | 0.000 | 0.000 | 0.000 |

| final\_match\_reported | 0.000 | 0.000 | 0.000 |

checks_consistent_ok takes the largest hit (−0.400), dropping from 0.800 to 0.400. This signal measures whether the model's intermediate reasoning steps are internally self-consistent. The Q4\_K\_M degradation here is the root cause of the json\_multistep pass rate drop: the model fails ms\_med\_02 on consistency alone, and ms\_hard\_01 on all signals.

| Signal | Rate |

|---|---:|

| turn1\_parse\_ok | 1.000 |

| turn2\_parse\_ok | 1.000 |

| turn2\_exact\_match | 1.000 |

toolcall\_only (Q4\_K\_M)

Recommended Use Cases

✅ Deploy with Confidence (Q4\_K\_M)

  • Stateful multi-turn agents — Perfect two-turn state retention (1.000). Reliable at 0.40 sec/case.
  • Structured JSON outputs (single-step)json and fuzz both achieve bucket\_score 10.000. Valid constraint-adherent outputs every case.
  • Hybrid brief + JSON responsesmixed_brief_json passes at 1.000. Fast at 0.52 sec/case.
  • Long-context document processing — 128K token context window is the key differentiator for this model. Suitable for full-document Q&A, multi-document comparison, and long-form extraction tasks.
  • Multilingual structured tasks — Trained on 9 languages. Reliable for non-English structured output pipelines.
  • Tool-calling with response scaffoldingtoolcall pass rate holds at 1.000. Use stage-1 tool dispatch reliably; add final-answer validation for downstream computation (see tool\_02 finding).

⚠️ Use with Guardrails (Q4\_K\_M)

  • Multi-step planning at easy-to-medium difficulty — ms\_easy\_01 and ms\_med\_01 pass. ms\_med\_02 fails on internal consistency. Use with an external validation loop for any planning task beyond trivial difficulty.
  • Post-tool answer validationtoolcall dispatches correctly but tool\_02 returns a wrong final answer. Validate model output after tool execution, not just the tool call itself.
  • Bare tool-call dispatchtoolcall_only fails on args (0.000). Add a schema enforcement layer or use scaffolded tool calling.

❌ Not Recommended (Q4\_K\_M)

  • Hard multi-step planning — ms\_hard\_01 fails on all four gating signals simultaneously. Do not deploy for hard planning tasks without F16 or an external planner/verifier.
  • MCQ without A-bias mitigation — Three of five MCQ cases fail at Q4\_K\_M, all defaulting to A. Add chain-of-thought prompting or answer validation for MCQ-style pipelines.

128K Context Window — Deployment Considerations

Mistral-Nemo's 128K context window is a meaningful production advantage for document-intensive applications. At Q4\_K\_M (7.48 GB model weight), actual usable context depends on KV cache VRAM overhead:

| Context Length | Approx. KV Cache | Total VRAM Needed | Fits on |

|---|---|---|---|

| 8K tokens | ~0.5 GB | ~10 GB | T4 16 GB |

| 32K tokens | ~2 GB | ~12 GB | T4 16 GB · RTX 4080 |

| 64K tokens | ~4 GB | ~14 GB | A10G 24 GB · RTX 4090 |

| 128K tokens | ~8 GB | ~18 GB | A10G 24 GB · RTX 4090 |

Set n_ctx in llama-cpp-python to the actual context length you need — do not default to 128K if your use case only needs 8K. Unnecessary context allocation wastes VRAM and slows inference.

The complete breakdown of ms\_hard\_01 at Q4\_K\_M — all four gating signals failing simultaneously — and the tool\_02 final\_mismatch are findings that only appear when you run both the F16 and quantized variant against the same behavioral test suite. Neither shows up in standard benchmarks. Neither is visible from casual testing. Both have direct consequences for production deployment decisions.

A model that dispatches tools correctly but gives wrong answers, and that fails completely on hard planning cases, needs to be known before it goes to production — not after.

👉 Book a Scoping Call — Discuss your model selection, quantization strategy, or deployment architecture directly with Patrick.

👉 Request an Evaluation Report — A full quant_eval behavioral audit: per-family pass rates, F16 vs. quantized delta analysis, failure cluster diagnostics, and a deployment recommendation. Engagements from $2,500.
