💻 Next-Codex (L846MoE)

Code your future with our models.

---

📖 Overview

Next-Codex is a high-performance, specialized Mixture-of-Experts (MoE) Large Language Model designed specifically for code generation, debugging, and software engineering tasks.

Unlike traditional dense models, Next-Codex utilizes a sparse architecture with 30 Billion total parameters, but only activates 3 Billion parameters per token. This unique design allows it to deliver the deep reasoning capabilities of a massive model while maintaining the ultra-low latency and inference cost of a lightweight 3B model. It is fine-tuned on a massive corpus of code across 20+ programming languages, making it the most efficient coding assistant in its class.

⚡ Highlights

• 🇹🇷 Türkiye’s First Specialized MoE Coding Model: Designed for speed and precision.
• 🚀 Hyper-Efficient Inference: Runs with 3B active parameters, enabling deployment on consumer GPUs (e.g., RTX 3090/4090).
• 💻 SOTA Coding Performance: Surpasses Claude Sonnet 4 and rivals o3-High in Python & JavaScript benchmarks.
• 🌍 Polyglot Programming: Master-level proficiency in Python, JS/TS, Rust, Go, C++, SQL, and Swift.
• 🧠 Context-Aware Debugging: Excellent at understanding large codebases and suggesting architectural improvements.
• 🏢 Production Ready: Optimized for autocomplete, unit test generation, and docstring creation.

🚀 Installation & Usage

Note: Due to the MoE architecture, this model is memory efficient. You can run it comfortably on 24GB VRAM GPUs (4-bit quantization highly recommended for lower VRAM).

!pip install unsloth transformers

from unsloth import FastLanguageModel

# Load the MoE Model
model, tokenizer = FastLanguageModel.from_pretrained(
    "Lamapi/next-codex",
    load_in_4bit = True, # Optimized for 24GB VRAM
)

messages = [
    {"role": "system", "content": "You are Next-Codex, an expert software engineer and AI coding assistant."},
    {"role" : "user", "content" : "Write a highly optimized Rust function to calculate the Fibonacci sequence using memoization."}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize = False,
    add_generation_prompt = True
)

from transformers import TextStreamer
_ = model.generate(
    **tokenizer(text, return_tensors = "pt").to("cuda"),
    max_new_tokens = 2048,
    temperature = 0.2, # Lower temperature for code precision
    top_p = 0.95,
    streamer = TextStreamer(tokenizer, skip_prompt = True),
)
