CoALa-1 (183M Multilingual Llama-Base)

CoALa-1 is a highly efficient, multilingual base model with 183 million parameters. Built on a modern Llama-based architecture, it is designed to deliver maximum performance in a compact size, making it one of the top-performing models in the sub-200M parameter class.

Key Highlights

Architecture: Llama-based (utilizing RoPE, RMSNorm, and SiLU) for superior stability and reasoning compared to older GPT-2 structures.
Top 3 Performance: In its weight class (<200M), CoALa-1 outperforms industry standards like Meta's OPT-125M and competes directly with OpenAI's GPT-2 Small.
Multilingual Power: Trained from scratch on high-quality Wikipedia data in 7 languages (English, German, Spanish, French, Portuguese, Italian, Russian).
Custom Tokenizer: Features a 64,000 vocab Byte-level BPE tokenizer, optimized for multilingual efficiency.

⚠️ Important Note: Base Model vs. Instruct Model

CoALa-1 is a Base Model (Pretrained). It has been trained to predict the next token on a massive Wikipedia corpus but has not yet undergone Instruction Fine-Tuning (SFT) or RLHF.

What this means for users:

The model will not answer questions like a chatbot (e.g., "How are you?").
Instead, it will continue a given text in a neutral, encyclopedic style.

Evaluation Results

CoALa-1 was evaluated using the lm-evaluation-harness. It shows a strong performance in factual knowledge compared to other models in its weight class.

Benchmark	Metric	CoALa-1 (183M)	GPT-2 (124M)	OPT-125M
ARC-Easy	acc_norm	28.87%	27.00%	24.50%
HellaSwag	acc_norm	26.96%	28.50%	26.00%
