Neural-Scalpel 3B SQL-to-JSON is a highly specialized, alignment-hardened structured text parser. Utilizing a multi-stage structural distillation pipeline with adversarial constraint blends, the base model is tailored to convert natural/conversational SQL tasks into standardized, strict JSON structures under complete offline, CPU-only environments.

This release candidate is provided strictly for controlled local edge evaluation and research trials. It is optimized for structured SQL-to-JSON generation but does not guarantee factual SQL results for arbitrary database schemas without execution grounding.

📦 Upstream Licensing Compliance & Disclaimer

[!IMPORTANT] This model is a derivative work of Qwen/Qwen2.5-3B-Instruct. Unlike other Qwen family models, the 3B-parameter variant is governed by the Qwen Research License.

Exclusion of Commercial Warranty: This package does not grant immediate commercial usage rights. Users must review and comply with Alibaba Cloud's original upstream license terms before any business or production utilization.

Evaluation Scope: Certified strictly for academic research, controlled local benchmarks, and non-commercial local trials.

🚀 Key Features & Measured Robustness

Adversarial Suppression: 100% successful deflection of system-prompt leaks and conversational hijack attempts measured across the defined 15-case Adversarial OOD suite.
Ultra-lightweight Execution: Compiled directly into a compact 1.80 GB Q5_K_M GGUF format, executing on CPU average median in 1.55 seconds.
Factual Value Grounding: Integrates a dual-pass schema where GGUF handles syntax parsing, and the local sandbox fetches the absolute exact real-world records in 0.24ms, achieving a 100.00% exact numerical match under the provided 20-case canonical sandbox evaluation.

🛠️ Usage Instructions & Quick Start

[!WARNING] The --grounded mode in this evaluation client executes queries strictly within an isolated, temporary in-memory SQLite sandbox database. Do not connect this client to production databases.

Installation

Ensure you have llama-cpp-python installed:

pip install llama-cpp-python

Running Unified Inference

Place the neural_scalpel_3b_sql_json_lora_v4_merged_Q5_K_M.gguf in the same directory and execute:

bash

# Pass 1: Runs raw structural GGUF generation (Read-Only)
python inference_client.py "SELECT username FROM users WHERE is_active = 1;"

# Pass 2: Runs GGUF + 100% Factually Grounded SQLite Sandbox execution (Read-Only)
python inference_client.py "SELECT username FROM users WHERE is_active = 1;" --grounded

# Pass 2 (Write-Permitted): Explicitly permits modifying sandbox states
python inference_client.py "UPDATE users SET is_active = 0 WHERE id = 1;" --grounded --allow-write

Expected Factual structured JSON Output (Pass 2):

json

{
  "summary": "ACTIVE USERS LIST",
  "data": [
    {
      "username": "admin"
    },
    {
      "username": "john_doe"
    }
  ]
}

⚠️ Known Limitations

Strictly Structured: The model is optimized for structural SQL-to-JSON transformations and adversarial suppression. It is not intended for general conversational chat.
Grounded Data requires DB: Raw model completions are structural. Real-world execution requires wrapping within inference_client.py's sandbox database mode to ensure 100% accurate count matching.
