Enterprises Face Routing Challenges as Multi-model AI Gains Ground

In recent years, artificial intelligence (AI) has become increasingly integral to business operations. As a result, application teams have begun moving AI inference into production systems, introducing new complexities in traffic management, identity controls, and observability.

According to F5’s 2026 State of Application Strategy Report, 78% of organizations operate their own inference services, with 77% identifying inference as their primary AI activity.

As a result, enterprises face the challenge of distributing inference traffic efficiently, securely, and reliably. This requires orchestration of multiple models, centralized controls, and shared protection systems, making it essential for businesses to invest in robust infrastructure and security measures.

The Shift Towards Multi-model AI

The shift towards multi-model AI is driven primarily by operational and business requirements. Organisations need to manage inference traffic across multiple models to support availability, preserve existing integrations, and control operational costs.

Selecting AI models based on business and technical requirements, including cost optimization, compliance, resiliency, API compatibility, and model-specific capabilities
Designing and managing systems that govern how inference traffic is routed, constrained, secured, and observed
Leveraging AI to enhance decision-making and automate operational tasks within defined limits
Coordinating multiple AI models and inference services to support availability, compliance, and operational requirements

Organizations are leveraging AI to enhance decision-making and automate operational tasks within defined limits, coordinating multiple AI models and inference services to support availability, compliance, and operational requirements.

Key Challenges

Determining which model should handle each request based on API compatibility, latency, availability, security, compliance, and cost is a key challenge that businesses need to address. Investing in robust infrastructure and security measures is essential to ensure efficient, secure, and reliable distribution of inference traffic.

With the number of AI models used by organisations continually increasing, the ability to manage inference within distributed systems environments becomes essential. Designing and managing systems that govern how inference traffic is routed, constrained, secured, and observed is becoming a critical architectural priority for organisations treating inference as a new application tier.
