Trouter-20B is a state-of-the-art decoder-only transformer language model with 20 billion parameters. Designed for versatility and performance, it excels at a wide range of natural language understanding and generation tasks including reasoning, question answering, creative writing, code generation, and conversational AI.

✨ Key Features

• 20B Parameters: Optimal balance between performance and computational efficiency
• 4K Context Length: Process and generate longer sequences with 4096 token context window
• Apache 2.0 License: Fully open for commercial and research use
• Optimized Architecture: Efficient attention mechanisms with GQA (Grouped Query Attention)
• Multi-lingual Capable: Strong performance on English with support for multiple languages
• Quantization Ready: Compatible with 8-bit and 4-bit quantization for reduced memory footprint
• Chat Optimized: Built-in chat template for conversational applications

🚀 Quick Start

Installation

pip install transformers>=4.38.0 torch>=2.0.0 accelerate bitsandbytes

Basic Usage

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

# Load model and tokenizer
model_id = "Trouter-Library/Trouter-20B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

# Generate text
prompt = "Explain the concept of neural networks:"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Memory-Efficient Loading (4-bit)

from transformers import BitsAndBytesConfig

# Configure 4-bit quantization
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16
)

model = AutoModelForCausalLM.from_pretrained(
    model_id,
    quantization_config=bnb_config,
    device_map="auto"
)
