The Rise of ‘local AI’: Why More Users Are Running Models Offline

August 31, 2025

For years, accessing Artificial Intelligence has meant relying on cloud-based services, paying by the token for each interaction. However, a new trend is emerging: running elegant AI models directly on personal computers and servers. This shift, driven by concerns over cost, privacy, and control, is making “local AI” an increasingly viable option for individuals and organizations alike.

Currently, providers of foundational AI models often operate at a financial loss, anticipating future profits through subscription fees or data utilization. As the demand for AI grows, these costs are likely to increase, prompting users to explore alternatives.

Distrust in Big Tech Fuels the Shift

A notable catalyst behind the embrace of local AI is waning trust in major technology corporations. Recent Pew Research Center data revealed that 81 percent of Americans express anxieties about the potential misuse of their data by AI companies. This apprehension has prompted regulatory scrutiny,with the federal Trade Commission warning AI developers to uphold commitments regarding customer data privacy,and subsequent changes made under the current governance.

Even assurances from companies like OpenAI – that user chat logs will be forgotten upon request – are met with skepticism, as legal battles, such as the ongoing case with The New York Times, demonstrate an inability to fully erase stored data.

The Benefits of Owning Your AI

Beyond privacy,several factors are driving the adoption of local large language models (LLMs). Cost savings are paramount, as usage-based pricing models can become prohibitive for intensive users. Moreover, running models locally provides greater control over data and reduces reliance on internet connectivity.

Environmental concerns are also playing a role. Data centers consume a significant amount of energy- estimated to reach over 9 percent of the United States’ total electricity consumption by 2030 – and require significant water resources for cooling. Running models on personal hardware can potentially lower this environmental impact, particularly when powered by renewable energy sources.

How Does Local AI Work?

Running AI models locally requires optimizing the models for available hardware. A key technique is “quantization”, which reduces the precision of the numerical values within the model, decreasing storage and processing demands. This allows for deployment on systems with limited resources.

according to AI infrastructure firm Modal,a half-precision model requires approximately 2 GB of VRAM per billion parameters. Increased VRAM capacity, or further quantization, enables the running of larger models. As of July 2024, the average

The Shift Towards Decentralized AI

For years, accessing powerful language models meant relying on cloud-based APIs from major tech companies. Now, a notable shift is underway: the rise of local language models (LLMs) and self-hosted AI.This isn’t just a trend for tech enthusiasts; it’s a strategic move for individuals and businesses seeking greater control, privacy, and cost-effectiveness. The ability to run AI models locally is becoming increasingly accessible, fueled by advancements in hardware and software.

Understanding Local Language Models

Local LLMs are essentially AI models that run directly on your own hardware – your computer, server, or even edge devices – rather than relying on a remote server. This contrasts sharply with services like OpenAI’s GPT models or Google’s PaLM, which are accessed via the cloud.

Here’s a breakdown of key terms:

Large Language Models (LLMs): AI algorithms trained on massive datasets of text to understand and generate human-like language.

Self-Hosting: The practice of running software on your own infrastructure, giving you complete control over the environment.

Inference: The process of using a trained model to generate predictions or outputs.Running LLM inference locally is a core component of self-hosting.

Quantization: A technique to reduce the size and computational requirements of LLMs, making them suitable for running on less powerful hardware.

Why the Growing Popularity? Key Drivers

Several factors are driving the adoption of self-hosted AI solutions:

Data Privacy & Security: Perhaps the biggest driver. Keeping your data within your own infrastructure eliminates the risk of sensitive information being exposed to third-party servers. This is crucial for industries like healthcare, finance, and legal.

Cost Savings: While initial hardware investment may be required,long-term costs can be significantly lower than ongoing API usage fees,especially for high-volume applications. Consider the cost of thousands of API calls versus the one-time expense of a powerful GPU.

Customization & Control: Self-hosting allows for complete customization of the model and its environment. You can fine-tune the model on your own specific data, optimize it for your unique use case, and integrate it seamlessly into your existing systems.

Reduced Latency: Running AI on-premise or locally eliminates network latency, resulting in faster response times. This is critical for real-time applications like chatbots and interactive tools.

Offline Functionality: Local models can operate even without an internet connection, making them ideal for remote locations or situations where connectivity is unreliable.

Avoiding Vendor Lock-in: Reliance on a single cloud provider can create vendor lock-in. Self-hosting provides independence and versatility.

Popular Local LLMs & Tools

The landscape of open-source LLMs is rapidly evolving. Here are some prominent examples:

Llama 2 (Meta): A powerful and versatile open-source LLM that has become a popular choice for self-hosting.

Mistral 7B: Known for its strong performance and relatively small size, making it suitable for a wider range of hardware.

Falcon: Another competitive open-source model offering strong capabilities.

GPT4All: A project focused on making LLMs accessible to everyone, with easy-to-use tools for running models locally.

Ollama: Simplifies the process of running, creating, and sharing LLMs locally.

LM Studio: A GUI application for discovering, downloading, and running local LLMs.
