Edge AI creates opportunities to make products, equipment and operational systems more responsive, resilient and capable.
Realising those opportunities requires an understanding of the operational challenges within an industry, alongside an in-depth understanding of what Edge AI can do.
The goal is not to deploy the most powerful AI model wherever possible. It is to use as much intelligence as the application requires, where it can create the greatest practical value.
What is Edge AI
Edge AI describes artificial intelligence running on computing equipment located at or near the point where data is generated. Data can be interpreted locally and used to support a direct response, without first sending all raw information to remote cloud infrastructure.
Key characteristics of Edge AI include:
- Responds locally – Supports low-latency decisions and direct interaction with products, machines and processes.
- Operates reliably – Maintains functionality where connectivity is unavailable, limited or unsuitable.
- Keeps data local – Processes sensitive information and high-volume sensor or video data close to its source.
The edge is not defined by a particular device or model size. It can support applications ranging from detecting a single event using very little power to helping operators understand and interact with complex connected systems.

Choosing where intelligence belongs
Edge AI is not inherently better than cloud processing. The right architecture depends on what the system needs to achieve.
Local processing is most useful where systems need to respond quickly, continue operating without reliable connectivity or keep sensitive and high-volume data close to its source. Cloud platforms can provide centralised computing, model training and longer-term analysis.
In many applications, the most effective approach is hybrid: immediate decisions happen at the edge, while the cloud supports the wider system.
Edge – Immediate local decisions, resilience and greater control over data.
Cloud – Centralised computing, model management and cross-site analysis.
Hybrid – Local action supported by central training, oversight and analysis.
Edge AI across products, processes and systems
Edge AI can be applied across a wide range of products, operational environments and industries. The opportunity differs in each case, shaped by the data available, the conditions in which the system must operate and the decision it needs to support.
Across these applications, selecting the right data and sensing strategy can be as important as selecting the model itself. The most obvious measurement is not always the most informative.
From opportunity to implementation
A trained model is only one part of a successful Edge AI system. Its value depends on how well it works with the data, hardware, software and operating environment around it.
42T combines Edge AI expertise with a detailed understanding of the products, processes and environments in which these systems will be deployed. This multidisciplinary perspective helps us assess where the technology can be useful, anticipate the practical challenges involved and develop systems that perform reliably in real-world conditions.
Effective Edge AI should support the people, products and processes around it. Our approach combines technical capability with human judgement to ensure that the technology addresses a clearly defined need and creates practical value.
Our team integrates Edge AI into system-level solutions, and excels at machine learning deployment.
