Best Local AI Models for Fastest Possible Local Inference
Models tuned for maximum tokens/sec — small, distilled, MoE.
For the fastest possible local inference, use Qwen 2.5 0.5B Instruct. It offers the best balance of speed, quality, and resource efficiency, making it the ideal choice for most applications.
For the fastest possible local inference, users need models that can process a high number of tokens per second while maintaining a low memory footprint. This means optimizing for smaller, more efficient models that can run on consumer-grade hardware without sacrificing performance. Local inference is crucial for applications where latency and data privacy are paramount, as it eliminates the need to send data to a remote server.

Qwen 2.5 1.5B1.5B · apache-2.0 · min 1.5GB
A robust model for higher-end systems.
Qwen 2.5 1.5B is a solid choice for users with slightly more powerful hardware. With 1.5B parameters and a minimum VRAM requirement of 1.5GB, this model, licensed under Apache-2.0, offers a 98% quality score. While it requires a bit more memory than the top three picks, it provides a noticeable boost in performance, making it ideal for applications that demand both speed and accuracy. It’s a great option for users who want a bit more power without breaking the bank.
- #5
Qwen 2.5 3B3B · apache-2.0 · min 2.5GB
A powerful model for mid-range hardware.
Qwen 2.5 3B rounds out the top five with 3B parameters and a minimum VRAM requirement of 2.5GB. Licensed under Apache-2.0, this model maintains a 98% quality score, making it a strong choice for users with mid-range hardware. While it’s not as lightweight as the top picks, it offers a good balance of performance and resource efficiency, making it suitable for more demanding tasks such as complex text generation or natural language understanding.
Hardware guidance
For the fastest possible local inference, users should aim for at least 8GB of VRAM to ensure smooth operation of the larger models. However, for the best performance, 12GB or more is recommended, especially if you plan to run multiple models simultaneously or handle more complex tasks. Users with 16GB or 24GB+ of VRAM will have the flexibility to run even the largest models without performance degradation, making them ideal for professional or enterprise-level applications.
When to skip local
While local inference offers significant advantages in terms of speed and privacy, there are scenarios where a hosted API might be preferable. For example, if you need access to the latest and most powerful models without the need for expensive hardware, or if your application requires seamless scaling and failover, a hosted API like Anthropic or OpenAI could be a better fit. Consider these options when local resources are limited or when you need advanced features not available in local models.
