SFM-2: Syntax-aware Foundation Model for Programming Languages

License: MIT Python 3.8+ Hugging Face Paper Demo

🧠 Revolutionary transformer architecture with syntax-aware attention mechanisms for next-generation programming language understanding and code generation

🎯 Model Overview

SFM-2 (Syntax-aware Foundation Model 2) represents a breakthrough in AI-assisted programming. Unlike traditional language models that treat code as plain text, SFM-2 understands the structural and semantic relationships in programming languages through novel syntax-aware attention mechanisms.

🚀 Key Innovations

  • 🧠 Syntax-aware Attention: First-of-its-kind attention mechanisms that understand programming language structure
  • 🎯 AST-guided Processing: Leverages Abstract Syntax Trees for superior code understanding
  • 🔄 Multi-language Mastery: Trained on 6+ programming languages with deep structural understanding
  • Efficient Fine-tuning: Advanced LoRA and parameter-efficient training methods
  • 🛡️ Production Ready: Enterprise-grade API with intelligent fallback systems
  • 🎓 Research-backed: Built on peer-reviewed research in cognitive accessibility and syntax-aware AI

🚀 Quick Start

Using with Transformers 🤗

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

# Load model and tokenizer
model_name = "Bryantad/SfM-2"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto"
)

# Generate code with syntax awareness
prompt = "def fibonacci(n):"
inputs = tokenizer(prompt, return_tensors="pt")

with torch.no_grad():
    outputs = model.generate(
        inputs.input_ids,
        max_length=150,
        temperature=0.7,
        do_sample=True,
        pad_token_id=tokenizer.eos_token_id,
        repetition_penalty=1.1
    )

generated_code = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(generated_code)

🏗️ Model Architecture

💡 Core Innovation: Syntax-aware Attention

SFM-2 introduces groundbreaking attention mechanisms that understand programming language syntax at a fundamental level:

# Traditional attention treats code as text
attention_scores = softmax(Q @ K.T / sqrt(d_k))

# SFM-2 syntax-aware attention incorporates structural understanding
syntax_bias = compute_syntax_bias(ast_structure, token_types, scope_info)
structural_attention = incorporate_ast_guidance(Q, K, V, syntax_tree)
attention_scores = softmax((Q @ K.T + syntax_bias + structural_attention) / sqrt(d_k))

🧩 Architecture Components

Component Description Innovation
Tokenizer Syntax-preserving tokenization Maintains code structure and semantics
Encoder Multi-layer transformer with syntax-aware heads AST-guided attention patterns
