All You Need To Know About Running LLMs Locally
Data Privacy and Security
Protecting sensitive information requires understanding the differences between local and cloud AI processing. These two approaches handle data in fundamentally different ways, and knowing how each works can help you make better decisions for your AI strategy.
Local AI Processing: Full Control
Local AI processing keeps all data within your organization’s infrastructure. For example, JPMorgan Chase implemented a local AI system in 2023 that processed 1 million daily transactions. The results? A 40% drop in false positives and a 25% improvement in fraud detection.
Cloud AI Processing: Distributed Approach
Cloud-based AI relies on remote servers spread across different locations. While cloud providers use strong security measures, the distributed nature of cloud systems introduces extra challenges for protecting data. Still, 94% of enterprises use cloud services for AI/ML workloads, even though 66% list data privacy as a major concern[3].
Compliance and Regulatory Factors
Local AI often offers an edge when it comes to meeting compliance requirements. In fact, 68% of compliance officers feel more confident about regulatory adherence when using local AI systems[2]. Additionally, data residency laws play a big role in platform decisions.
Data Residency and Sovereignty
For organizations managing highly sensitive information, data residency is a key factor. Local AI ensures full control over where data is stored, while cloud solutions can involve data moving across borders. A survey found that 72% of IT leaders prioritize data residency when selecting AI platforms[2].
Security Measures in Practice
Local and cloud systems take different approaches to security:
- Local AI: Relies on role-based access control and operates within the organization’s existing infrastructure. Network isolation provides an added layer of protection.
- Cloud AI: Includes measures like multi-factor authentication, IP whitelisting, and API keys. Cloud platforms also offer advanced tools like automated threat detection and response systems.
Anonymization and Data Protection
When handling sensitive data, anonymization is critical. Studies show that custom local anonymization solutions outperform cloud alternatives by 5% in preventing re-identification[2]. This is especially important for organizations dealing with personal data or proprietary information.
While security is a major factor in choosing between local and cloud AI, performance considerations are just as influential in the decision-making process.
Speed and Resource Usage
The speed at which AI processes data and the resources it uses are key factors in deciding whether to go with local or cloud-based solutions. Knowing how these systems perform helps in choosing the right setup for specific needs.
Processing Speed and Latency
Local AI systems typically deliver latency between 1-10ms, making them ideal for tasks needing quick responses. On the other hand, cloud platforms shine in handling complex computations, thanks to their access to powerful GPU clusters and scalable resources [2].
Hardware Requirements and Scalability
Local and cloud AI setups have very different hardware and scalability needs:

Scalability | Limited by the device | Dynamically scalable resources |
Concurrent Tasks | Limited processing capabilities | Handles millions of users [9] |
Storage | Local storage required | Cloud-based storage |
For demanding applications like large language models, cloud solutions clearly stand out. For example, ChatGPT's cloud-based setup supports millions of users at the same time [9], while local systems struggle due to hardware limitations.
Energy and Resource Efficiency
Running GPT-3 in the cloud uses about 0.4 kWh per hour [8], but this is often offset by the efficiency of modern data centers.
Network Dependencies
Cloud AI heavily depends on a stable internet connection. While it offers immense computational power, unreliable connectivity can significantly affect performance.
Mobile and IoT Considerations
In mobile and IoT environments, local processing can cut data transmission by up to 90% compared to cloud solutions [6]. This is particularly useful for edge computing, where minimizing data transfer is critical.
Resource Optimization Strategies
When deciding between local and cloud AI, consider these two key factors:
- Local AI is better for real-time tasks and privacy-sensitive operations.
- Cloud AI is more suited for complex computations and large-scale data analysis.
These trade-offs directly impact costs and efficiency, which will be explored in the next section.

Price Comparison
Breaking down the costs of local versus cloud AI processing involves looking at both upfront and ongoing expenses. These costs can vary widely based on how you use the system, the scale of your operations, and your specific needs.
Initial Investment Costs
Setting up local AI processing requires a hefty upfront investment. Here’s what you might need to budget for:
