CodeBase-280B: Next-Gen MoE LLM Launched

Join Community

Summary

The 404Development | Software Hub community has launched the first phase of CodeBase-280B, their next-generation Mixture of Experts (MoE) Large Language Model. This model features 128 experts with 9 active per token, a massive 384,000 token context window, and optimized inference via 8-bit quantization. This launch is significant because it offers a highly scalable and efficient LLM designed for advanced performance across multi-GPU setups.

🚀 Introducing CodeBase-280B: Phase 1

Hey everyone,
We’re excited to share the first phase of CodeBase-280B, our next-generation language model built for performance, scalability, and advanced AI capabilities. Here’s what makes it special:

💡 Key Highlights

  • Mixture of Experts (MoE): 128 experts with 9 active per token, meaning the model only uses the parts it needs for efficiency and speed.
  • Massive Context Window: Handles up to 384,000 tokens at once, allowing it to understand extremely long documents or conversations.
  • Compressed Attention: Optimized memory usage with partial KV sharing to keep inference fast.
  • Efficient Inference: 8-bit quantization with KV cache compression reduces memory requirements without sacrificing quality.
  • Parallel & Distributed: Designed for multi-GPU setups with support for distributed training and mixed precision (bfloat16) for optimal performance.

📊 Specs at a Glance

  • Hidden Size: 7,168
  • Layers: 75
  • Attention Heads: 52
  • Experts: 128 total, 9 active
  • Context Window: 384,000 tokens
  • Parameters: ~280B total (~18B active at a time)
  • Vocabulary: 51,200 tokens

🛠️ Project Structure & Usage

CodeBase-280B includes everything you need to train, test, and run inference on the model, including:

  • Transformer architecture and MoE modules
  • Compressed attention and RoPE positional encoding
  • Quantization utilities for memory-efficient inference
  • Training scripts with multi-GPU support
  • Open-source configuration for customization

Installation is simple: clone the repo and install dependencies via pip. You can train, generate text, benchmark, or run tests with provided scripts.
