In the ever-evolving AI landscape, accessibility and efficiency are becoming more critical than ever. While large-scale language models have significantly advanced natural language processing (NLP), their high costs and proprietary restrictions often prevent researchers and smaller organizations from leveraging their potential. The demand for open-source, high-performance models that foster innovation without the usual limitations is stronger than ever.
Introducing AMD Instella
AMD has taken a major leap forward by introducing Instella, a family of fully open-source language models designed for efficiency and accessibility. With 3 billion parameters, Instella offers a robust alternative in the AI ecosystem, striking the perfect balance between performance and scalability. By making Instella open-source, AMD is empowering researchers, developers, and enterprises to study, customize, and deploy an advanced NLP model tailored to their specific needs—without barriers or licensing constraints.

Technical Overview: Architecture & Performance
At its core, Instella features an autoregressive transformer architecture with 36 decoder layers and 32 attention heads. This structure allows the model to process sequences of up to 4,096 tokens, enabling it to handle complex language tasks with enhanced contextual understanding. With a vocabulary of approximately 50,000 tokens, powered by the OLMo tokenizer, Instella can efficiently generate and interpret text across diverse domains.
Optimized Training for Maximum Efficiency
AMD leveraged its Instinct MI300X GPUs for training Instella, utilizing a multi-stage process to optimize its learning and capabilities:
| Model | Stage | Training Data (Tokens) | Description |
| Instella-3B-Stage1 | Pre-training (Stage 1) | 4.065 Trillion | Initial training phase to build fundamental language skills. |
| Instella-3B | Pre-training (Stage 2) | 57.575 Billion | Further refining problem-solving abilities. |
| Instella-3B-SFT | Supervised Fine-Tuning (SFT) | 8.902 Billion (x3 epochs) | Instruction-following fine-tuning for improved task performance. |
| Instella-3B-Instruct | Direct Preference Optimization (DPO) | 760 Million | Fine-tuned for user-friendly and chat-based interactions. |
To enhance computational efficiency, AMD incorporated FlashAttention-2 for optimized attention processing, Torch Compile for acceleration, and Fully Sharded Data Parallelism (FSDP) to optimize resource usage. These innovations make Instella not only powerful but also highly efficient for real-world applications.
Benchmarking & Competitive Performance
Extensive testing of Instella reveals that it surpasses comparable open-source models in key NLP tasks. Compared to other 3B-parameter models, Instella delivers an 8% improvement across multiple standard benchmarks, including reasoning, problem-solving, and real-world application performance.
Instella’s instruction-tuned variants, refined through Supervised Fine-Tuning (SFT) and DPO, demonstrate remarkable effectiveness in interactive applications. When compared to models such as Llama-3.2-3B, Gemma-2-2B, and Qwen-2.5-3B, Instella proves itself as a highly competitive alternative. AMD’s commitment to full transparency—including the public release of model weights, datasets, and training hyperparameters—ensures that researchers and developers have complete access to explore, modify, and build upon this powerful model.
Why Instella Matters for the Future of AI
The release of Instella marks a significant step toward democratizing AI. By removing barriers to high-quality language modeling, AMD is enabling a new wave of AI-powered research, automation, and real-world applications. Instella’s powerful yet accessible design ensures that businesses, developers, and academics alike can leverage state-of-the-art AI without the usual costs and restrictions.
With NLP innovation accelerating, Instella positions itself as a transformative tool in the AI space. Whether for automated content generation, business intelligence, AI-driven chatbots, or advanced research, Instella is poised to drive the next wave of AI advancements.
