The BTLM-3B-8k-base, a cutting-edge Bittensor Language Model, redefines the capabilities of 3 billion parameter models. Trained on 627 billion tokens from SlimPajama, this model boasts an impressive 8k context length. Surpassing models trained on significantly larger datasets, BTLM-3B-8k-base achieves performance on par with open 7 billion parameter models. What’s truly groundbreaking is its adaptability: it can be quantized to a mere 4 bits, enabling deployment on devices with as little as 3GB of memory. This remarkable feat opens doors for personal AI assistants on mobile and IoT devices, ensuring local processing for enhanced privacy and independence from the cloud. With its Apache 2.0 license for commercial use, BTLM-3B-8k-base marks a significant stride towards a decentralized AI future.


Mamba-GPT-3b-v3 stands as a remarkable achievement among 3 billion-parameter LLM models, positioning itself as the premier choice on the Open LLM Leaderboard. This model’s prowess has transcended even the esteemed dolly-v2-12b, showcasing an exceptional leap in performance. Through meticulous fine-tuning of the open-lama model, Mamba-GPT-3b-v3 has achieved a remarkable feat by outperforming its progenitor across a spectrum of evaluation subtasks. Its current standing as the leading 3B model is further fortified by its ability to deliver performance akin to that of the larger llama-7b model. This triumph not only underscores the potential of compact LLMs but also paves the way for embedding potent AI assistants into resource-constrained devices, amplifying privacy and enabling local operations sans dependency on the cloud.


The “open_llama_3b_v2” is a significant step in the evolution of small-sized language models, demonstrating that a model with 3 billion parameters can excel. A notable achievement is its permissively licensed, open-source nature, allowing broader accessibility. Trained on diverse data mixtures, it serves as a seamless alternative to Meta AI’s LLaMA, offering compatibility with existing setups. This 3B model, trained on a massive 1 trillion tokens, showcases the potential of compact models to achieve impressive performance, paving the way for personal AI assistants on local devices, ensuring privacy and autonomy.


StableLM-Base-Alpha-3B-v2 represents a significant advancement in compact language models. Building upon the original Alpha models, this iteration introduces architectural enhancements like SwiGLU (Shazeer, 2020) and relies on superior data sources for improved performance. With a context length of 4096 tokens, it offers a broader understanding of text.

Key enhancements include the use of high-quality data like RefinedWeb and C4 instead of The Pile v2 Common-Crawl scrape. Notably, the model’s ability to sample web text at an increased rate of 71% as opposed to 35% has led to noteworthy improvements in downstream performance, showcasing the potential of compact models to outperform in various applications.
