SmolLM2 135M0.135B · apache-2.0 · min 0.6GB
The smallest and most efficient model for extremely constrained environments.
SmolLM2 135M Instruct is the smallest and most efficient model in this list, making it ideal for extremely constrained environments. With only 0.135B parameters and a minimum VRAM requirement of 0.6GB, it can run on virtually any GPU with 8GB of VRAM. Licensed under Apache-2.0, it provides a basic level of performance that is sufficient for simple tasks. While it may not be the best choice for complex applications, its extreme efficiency makes it a valuable option for users with very limited resources.
Hardware guidance
For low-VRAM (8GB GPU) setups, users should focus on GPUs like the NVIDIA RTX 3060, RTX 2080, or Apple M1 Max. These GPUs provide a good balance of performance and cost, making them suitable for running efficient models like those listed above. Users with 12GB or more VRAM can consider slightly larger models for better performance, while those with 16GB or more can explore even more powerful options. For 24GB+ VRAM, the sky's the limit, but for most low-VRAM users, the models in this guide will provide the best balance of performance and efficiency.
When to skip local
While local models offer significant advantages, there are scenarios where hosted APIs might still be preferable. For tasks requiring real-time processing or extremely high accuracy, hosted APIs like Anthropic's Claude or OpenAI's GPT-4 can provide superior performance. Additionally, if you have limited computational resources and need to scale quickly, hosted APIs offer a more flexible and scalable solution. Consider these options when local models fall short of your requirements.
