InCoder-32B (Industrial-Coder-32B) is the first 32B-parameter code foundation model purpose-built for industrial code intelligence. While general code LLMs excel at standard programming tasks, their performance often degrades in industrial scenarios that require reasoning about hardware semantics, specialized language constructs, and strict resource constraints.

InCoder-32B unifies code intelligence across:

Chip Design (Verilog / RTL)
GPU Kernel Optimization (CUDA / Triton)
Embedded Systems (ARM Cortex-M, STM32)
Compiler Optimization (x86-64 assembly, LLVM)
3D Modeling (CAD/CAM via CadQuery / OpenCascade)

The model supports a native long-context window of up to 128K tokens.

Training Pipeline: Code-Flow

InCoder-32B was developed using a three-stage Code-Flow pipeline:

Pre-training & Annealing: Curated industrial code mixed with general code pre-training using multi-level deduplication.
Mid-training (Context Extension): Progressive context extension from 8K to 128K tokens using synthetic industrial reasoning data and agent trajectories.
Post-training: Execution-grounded SFT across hardware design, GPU kernels, and systems programming.

Quickstart

Installation

pip install -U "transformers>=4.57.1" accelerate safetensors

Usage with Transformers

Note: The model uses a custom architecture, so trust_remote_code=True is required.

python

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "Multilingual-Multimodal-NLP/IndustrialCoder"

tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto",
    trust_remote_code=True,
)

messages = [{"role": "user", "content": "Optimize this CUDA kernel for better memory coalescing."}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer([text], return_tensors="pt").to(model.device)

with torch.no_grad():
    out = model.generate(**inputs, max_new_tokens=2048, temperature=0.6, top_p=0.85, top_k=20)

print(tokenizer.decode(out[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True))

Disclaimer

The model may generate incorrect or unsafe code. Always review and test outputs in a sandboxed environment before production use. Industrial code (RTL, embedded firmware, GPU kernels) requires expert human review before deployment.
