Choosing the right AI tool for your UK business can make or break your productivity gains. With OpenAI's GPT-5.2 and Anthropic's Claude Opus 4.6 dominating the enterprise AI landscape, you're likely wondering which offers better value for money.

I've spent the last three months testing both models across real UK business scenarios. Here's everything you need to know to make the right choice for your SME.
