IaC-Coder 1.5B — Infrastructure as Code Language Model

A small language model fine-tuned for DevOps Infrastructure as Code (IaC) tasks. Built on Qwen2.5-Coder-1.5B with LoRA SFT on real-world IaC commits.

Supported IaC Languages

Language	Use Case	Training Data
Terraform HCL	Cloud infrastructure provisioning	421 commit pairs
YAML (Ansible/K8s)	Configuration management, container orchestration	30,000 commit pairs (capped from 114K)
Dockerfile	Container image definitions	39 commit pairs
Shell/Bash	CI/CD pipelines, automation scripts	15,000 commit pairs (capped from 31K)
Nix	Reproducible builds	1,593 commit pairs
Makefile	Build automation	960 commit pairs
SaltStack	Configuration management	617 commit pairs
TOML	Application configuration	3,424 commit pairs

Quick Start

from transformers import pipeline
import torch

pipe = pipeline(
    "text-generation",
    model="Tejas86/iac-coder-1.5b",
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

messages = [
    {"role": "system", "content": "You are an expert DevOps engineer. Generate clean, production-ready Terraform HCL code."},
    {"role": "user", "content": "Task: Create an AWS S3 bucket with versioning enabled and server-side encryption\n\nGenerate the Terraform HCL code."},
]

output = pipe(messages, max_new_tokens=512, temperature=0.2, do_sample=True, top_p=0.9)
print(output[0]["generated_text"][-1]["content"])

Prompt Format

The model was trained with this conversational format:

System: You are an expert DevOps engineer specializing in Infrastructure as Code. Generate clean, production-ready {language} code.

User: Task: {natural language description}

Modify the following {language} file:
