AMD releases Instella: a series of fully open source state-of-the-art 3B parameter language models
In today’s rapidly evolving digital landscape, the need for accessible, effective language models is becoming increasingly apparent. Traditional large-scale models have a high level of natural language understanding and production, but for many researchers and smaller organizations, they are often out of reach. High training costs, proprietary constraints and lack of transparency can hinder innovation and limit the development of tailored solutions. As demand for balanced performance and accessibility models continues to grow, it is clear to call for service to academic and industrial communities without the typical barriers associated with cutting-edge technologies.
Introduction to AMD Instella
AMD recently launched Instella, a family of fully open source language models that contain 3 billion parameters. These tools are designed to be mere text models, providing a balanced alternative in a crowded field where not every application requires greater system complexity. By publishing Instella publicly, AMD provides the community with the opportunity to research, refine and adapt a range of applied models, from academic research to practical everyday solutions. This initiative is a welcome addition to those who value transparency and collaboration, making advanced natural language processing technologies easier to access without compromising quality.
Technical architecture and its benefits
At the heart of Instella is an autoregressive transformer model with 36 decoder layers and 32 attention heads. The design supports processing of verbose sequences (to 4,096 tokens), which enables the model to manage a wide range of text contexts and various language patterns. With a vocabulary of about 50,000 tokens managed by Olmo Tokenizer, Instella is perfect for interpreting and generating texts in various fields.
The training process behind Instella is also worth noting. The model was trained using AMD Instinct MI300X GPU, highlighting the synergy between AMD’s hardware and software innovation. The multi-stage training method is divided into several parts:
| Model | stage | Training data (token) | describe |
|---|---|---|---|
| Instella-3B Stage 1 | Pre-training (Phase 1) | 4.065 trillion | The first phase of pre-training is used to develop the level of natural language. |
| Instella-3b | Pre-training (Phase 2) | 5.7575 billion | The second phase is pre-trained to further enhance problem-solving ability. |
| Instella-3B-SFT | SFT | 8.902 billion (X3 era) | Supervised fine-tuning (SFT) to enable the following instructions. |
| Instella-3B teaching | DPO | 760 million | Align with human preferences and enhance chat functionality through Direct Preference Optimization (DPO). |
| All: | 4.15 trillion |
Other training optimizations have been employed, such as Flashattention-2 for efficient attentional computing, torch compilation for performance acceleration, and complete fragmented data parallelism (FSDP) for resource management. These choices ensure that the model not only performs well during training, but also runs efficiently when deployed.
Performance indicators and insights
Instella’s performance has been carefully evaluated for multiple benchmarks. Instella has an average improvement of about 8% in multiple standard tests compared to other open source models of similar scale. These assessments cover tasks ranging from academic problem solving to reasoning challenges, providing a comprehensive view of their abilities.
Instella’s instruction-tuning version, such as a version that is perfected through supervised fine-tuning and subsequent alignment processes, exhibits reliable performance in interactive tasks. This makes them suitable for applications that require a nuanced understanding of queries and balanced, background-aware response. In comparison with models like Llama-3.2-3B, Gemma-2-2B, and Qwen-2.5-3b, Instella has its own model, a competitive option for those who need a lighter but more powerful solution. The transparency of the project (through the open release of model weights, datasets, and training hyperparameters) can all increase its appeal to those who wish to explore the internal functioning of modern language models.
in conclusion
Instella released by AMD marks a step towards democratizing high-level language modeling technology. The clear design, balanced training method and transparent method of the model provide a solid foundation for further R&D. With its autoregressive transformer architecture and well-curated training pipeline, Instella is a practical and accessible alternative for a wide range of applications.
