As organizations increasingly recognize the transformative potential of large language models (LLMs), the decision to self-host these robust AI systems or rely on API-based solutions becomes a critical consideration.While using API-based models may seem straightforward, like driving a car, self-hosting requires building the entire infrastructure from the ground up – a process comparable to starting with just the engine. This transition significantly increases complexity, as organizations must take responsibility for various aspects previously handled by the API provider.We explore three key challenges that organizations must be prepared to address when self-hosting LLMs.

1. Infrastructure Management

Self-hosting requires setting up and maintaining the necessary infrastructure, such as batching servers, Kubernetes clusters, and function-calling mechanisms. These components were previously abstracted away by the API provider but now fall under the organization's purview. Failure to properly manage this infrastructure can lead to inefficiencies, bottlenecks, and potential downtimes.

2. Performance Optimization

Achieving optimal performance with self-hosted models is crucial, as there can be substantial differences in latency, memory usage, and compute costs between well-optimized and poorly implemented self-hosting stacks. Organizations must invest time and resources into fine-tuning their setups to ensure their LLMs operate at peak efficiency, minimizing latency and maximizing cost-effectiveness.

3. Guaranteed Output

API-based models often provide guaranteed structured outputs, such as JSON, simplifying integration and processing. In self-hosting setups, however, organizations must explicitly handle output formatting and ensure consistency across various use cases. This added complexity can introduce new challenges and potential points of failure if not appropriately managed.

Despite these challenges, the benefits of self-hosting LLMs can be significant, including cost savings, performance optimization, data privacy, and outage resilience. However, we cannot emphasize enough the importance of getting the self-hosting infrastructure right, as it can lead to substantial performance improvements, latency reductions, memory optimizations, and cost savings.

If you're deploying AI in your organization and considering self-hosting LLMs, carefully evaluating your readiness and capacity to overcome these challenges is essential. Partnering with experienced solution providers, like TitanML with its Takeoff Inference Server, can help you navigate the complexities of self-hosting and ensure a smooth, efficient, and optimized implementation.
