Llama EstLLM 8B 0825 Base

Please note that this is a base text completion model that has not been instruction-tuned. It is intended for fine-tuning on downstream tasks rather than direct use for chat or instruction-following.

meta-llama/Llama-3.1-8B continuously pre-trained on approximately 35B tokens. Continued pre-training was performed for a single epoch on:

—Estonian National Corpus (8.6B tokens)
—Python-Edu (3.3B tokens)
—FineMath4-Plus (9.5B tokens)
—General Instruction-Augmented Corpora (7.4B tokens)
—Cosmopedia v2 (6.9B tokens)

—Model type: Causal Language Model
—Language(s) (NLP): Estonian, English
—License: Llama 3.1 Community License Agreement

Limitations

In addition to the limitations of the original Llama 3.1 8B model, this model has the following:

—Somewhat limited context size due to the continued training being done with the sequence length of 4096 tokens.
