Claude Opus 4.5 Signals a New Era for Agentic AI in Customer Service

Anthropic’s newly released Claude Opus 4.5 has reached a remarkable milestone. It is now solving Anthropic’s own internal take home engineering test faster and more accurately than any human they have hired. This achievement highlights just how quickly frontier models are advancing.

Two developments stand out. The first is efficiency. Opus 4.5 delivers higher accuracy while using roughly half the tokens of its predecessor. That means greater intelligence per dollar and faster performance in real world workflows.

The second is agentic behaviour. A good example comes from the T2 Bench airline scenario. Instead of simply refusing a booking change, as the benchmark expected, Opus 4.5 worked through the problem and discovered a valid path by upgrading the cabin first and then modifying the flight. You can debate whether that is the ideal move, but the outcome shows the model is beginning to act more like an operator and less like a conversational assistant.

Anthropic’s expanded tool use is equally significant. Rather than loading thousands of tool definitions into the context window, Opus 4.5 can now search across a much larger universe of tools and retrieve only what it needs at the moment it is required. This reduces context overhead and enables richer, more dynamic workflows. AI agents can orchestrate multiple systems without exhausting token budgets.

For AI customer service platforms such as Airgentic, this trajectory aligns directly with our long term focus. Stronger reasoning, cheaper tokens and smarter tool routing are the foundations for agents that can safely manage more of the end to end customer journey. This includes diagnosing complex issues from lengthy PDF manuals, guiding users through multi system processes and invoking first party tools only when appropriate, all while remaining compliant with the guardrails expected by public sector and enterprise clients.

As these frontier models mature, our responsibility at Airgentic is to harness their capabilities within a framework of governance, retrieval and analytics. This ensures organisations get the benefits of agentic AI without unnecessary risk.

The frontier is moving quickly. The true differentiator will not simply be who has the most advanced model, but who can transform that capability into reliable and well governed customer experiences at scale.
