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 is the full-precision F16 baseline repository. The evaluated quantized variant is published separately:

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 7B 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 — the Q4_K_M pass rate in each of the eight quant_eval capability families for every model with a published run, marked ▼ degraded or ▲ improved where McNemar's paired test against the model's own full-weight baseline is significant, ordered by how many families degraded
- 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 Q4_K_M, 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 published quant_eval results: the quant_eval Public Corpus (DOI 10.5281/zenodo.22009419) and, for showcase models such as Ministral-3-14B-Instruct-2512, sealed run bundles published as summaries. The numbers are not opinionated; they're measured.
Model Description
This repository contains the full-precision F16 GGUF of Qwen/Qwen2.5-7B-Instruct, a 7-billion parameter instruction-tuned model developed by Alibaba Qwen Team (2024). Qwen2.5-7B-Instruct features a 32,768-token context window and multilingual instruction-following capability.
The F16 format preserves all original float16 weights without quantization. In the PBH Applied Systems evaluation pipeline, the F16 variant serves as the reference baseline: it is evaluated first, then the quantized variant is evaluated against the same fixture set, enabling direct measurement of quantization impact on behavioral fidelity.
For most production deployments, the quantized variant (Q4_K_M) is the appropriate choice — offering substantial footprint and speed gains with controlled behavioral tradeoffs. The F16 is the right choice when full weight precision is required — particularly for hybrid answer+JSON responses, where F16 scores 1.000 vs Q4_K_M's 0.925.

Comparability & Fixture Methodology
Fixtures Enable Valid Variant Comparison
The quant_eval evaluation harness uses a consistent fixture set to measure both full-precision and quantized variants. The F16 and Q4_K_M variants were evaluated under the same fixture set, enabling direct comparison.
Fixture Generation:
| Variant | Run ID | Fixture SHA256 | Evaluation Contract | Rationale |
|---|---|---|---|---|
| F16 & Q4_K_M | 20260814_234822 | 2a0f7cdd... |
v7.22.17:evaluation | Single run evaluating both runners sequentially |
What this means: Results are directly comparable. Both runners used identical fixtures, enabling precise measurement of Q4_K_M degradation relative to F16.
Per-Family Pass Rates — Full-Weight Baseline
All rates include 95% Wilson score confidence intervals. N = 200 cases per family.
| Family | Pass Rate | 95% CI | Notes |
|---|---|---|---|
| mixed_brief_json | 1.000 | [0.981, 1.000] | Perfect hybrid answer+JSON correctness |
| stateful_followup | 0.750 | [0.686, 0.805] | State tracking across turns; 50 turn-2 failures |
| toolcall_only | 0.805 | [0.745, 0.854] | Tool schema and arguments parsing |
| toolcall | 0.710 | [0.644, 0.768] | End-to-end tool dispatch and execution |
| mcq | 0.835 | [0.777, 0.880] | Multiple-choice semantic correctness |
| json | 0.425 | [0.359, 0.494] | Single-step structured JSON; 115 semantic mismatches |
| json_multistep | 0.355 | [0.292, 0.423] | Multi-step planning; oracle equivalence fails on 129 cases |
| fuzz | 0.520 | [0.451, 0.588] | Regression: property-based structural correctness |

Key Findings
Finding 1: Hybrid Responses Clean; Tool Selection Is the Weak Point
Qwen2.5-7B at full precision demonstrates perfect performance on hybrid responses (1.000). The hybrid family measures simultaneous natural-language and JSON correctness — a non-trivial capability that this model executes flawlessly. Tool dispatch is weaker: toolcall_only reaches 0.805, and all 39 failures are tool-name selection errors — argument construction passes on all 200 cases. End-to-end toolcall (0.710) shows the same pattern: all 58 failures are selection failures.
Finding 2: Multi-Step Planning — Difficult Task Even at F16
The json_multistep family tests multi-step planning, and at full precision this model achieves only 0.355 pass rate — below 40%. This reflects the model's inherent limitations on autonomous multi-step reasoning, not a precision artifact. Planning tasks benefit from external scaffolding (ReAct, hierarchical composition) rather than end-to-end autonomy at this model size.
Finding 3: Stateful Conversation — Three-Quarters Success
Stateful execution reaches 0.750, meaning one in four two-turn conversations fail on turn-2 state tracking. For applications requiring perfect state retention, this rate requires retry logic or validation. For general conversation, 75% success is usable but not enterprise-grade.
Quantization Variants Comparison
See how this model performs across the quantized variant. All evaluated under the same fixture set.
| Variant | File Size | VRAM | Speed | Stateful | Toolcall (end-to-end) | Hybrid | Best For |
|---|---|---|---|---|---|---|---|
| F16 | 15.2 GB | ~17 GB | 1.0× | 0.750 | 0.710 | 1.000 | Maximum fidelity; hybrid-response workloads |
| Q4_K_M | 4.68 GB | ~7 GB | 1.98× | 0.870 | 0.725 | 0.925 | Smaller and faster; mixed behavioral shifts — see card |
How to read this table: Speed is the observed evaluation wall-time ratio (F16 ÷ quantized) on the same RTX 4090 — not a controlled throughput benchmark. Generation throughput ratio for the same pair is 2.15× (55.44 → 119.12 tokens/sec).

Deployment Recommendations
✅ Deploy F16 when:
- Hybrid responses are central. F16 scores 1.000 on
mixed_brief_json; Q4_K_M drops to 0.925 (McNemar p = 6.1e−05). - Full weight precision is required. Note: this evaluation ran at a 4,096-token context; long-context behavior at either precision was not measured.
- You have enterprise GPU tier. A10G, RTX 4090, or dual T4.
⚠️ Avoid F16 if:
- Latency is the bottleneck. On the same RTX 4090, Q4_K_M achieves 2.15× generation throughput (1.98× observed wall-time) while improving stateful execution (0.750 → 0.870).
- Hardware is constrained to <17 GB VRAM. Q4_K_M fits in ~7 GB.
- Cost efficiency matters. 69% footprint reduction; significant losses are limited to hybrid responses (−0.075) and single-step JSON (−0.045).
