Serverlex Copilot 0.5B ⚡

Serverlex Copilot 0.5B is an offline, specialized AI diagnostic agent fine-tuned exclusively for Serverlex—the production-safe machine learning preprocessing, diagnostics, and serving platform.

At just 0.5 Billion parameters (~980MB in fp16, ~340MB in 4-bit), this model is lightweight enough to run locally on standard CPUs, Apple Silicon Macs, or edge environments with zero external API calls or GPU requirements.

📌 Capabilities

Pre-Flight Data Quality Audit Triage:
- Analyzes DataGuard logs and audit reports.
- Detects and explains ID memorization hazards, PII privacy concerns, and infinite value defects.
Mathematical Target Leakage Mitigation:
- Identifies suspicious proxy features ($|r| \ge 0.90$) and writes exact code to drop or remediate them.
Production Drift Interpretation:
- Interprets DriftDetector Population Stability Index (PSI) and Kolmogorov-Smirnov (KS) statistics.
- Prescribes retraining strategies and automated webhook alerting configurations.
Hardened Serving & Cryptographic Verification:
- Diagnoses HMAC-SHA256 signature verification mismatches and tamper attempts in ModelDeployer.
- Explains strict schema validation errors (unseen categories, missing features, invalid types).
End-to-End Workflow Synthesis:
- Generates production-ready, leakage-free Serverlex code (cleaners, pipeline encoders, nested CV tuners, and containerized FastAPI exports).

🚀 Quickstart & Inference

1. Directly via Serverlex (Recommended)

import serverlex

# Enable real-time automatic exception interception & guidance
serverlex.enable_auto_copilot()

# Or use the standalone Copilot agent
from serverlex import ServerlexCopilot

copilot = ServerlexCopilot()
log = "2026-11-06 10:39:12 [ERROR] DataGuard: Suspicious target leakage: feature post_op_charges has correlation 0.9842 with target total_hospital_cost"

print(copilot.diagnose_log(log))

2. Via Hugging Face `transformers`

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

MODEL_ID = "Uwais-ML-dev/serverlex-copilot-0.5b"

tokenizer = AutoTokenizer.from_pretrained(MODEL_ID)
model = AutoModelForCausalLM.from_pretrained(
    MODEL_ID,
    torch_dtype=torch.float16,
    device_map="auto"
)

prompt = """### Instruction:
Analyze this Serverlex log and output the fix.

### Input:
2026-11-06 10:39:12 [ERROR] DataGuard: Suspicious target leakage: feature 'hospital_charges' has correlation 0.9842 with target 'total_hospital_cost'

### Response:
"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=300, do_sample=False)
print(tokenizer.decode(outputs[0][len(inputs.input_ids[0]):], skip_special_tokens=True))
