The race for Generative AI Search Advanced capabilities: overview of 2025 developments and tools

Reasoning models
OpenAI’s o1 and o3 model has ushered in a new era of reasoning models implicated also as an additional layer in our research. This is clearly what makes OpenAI Deep Research so great. However now Grok 3, Claude 3.7 Sonnet and GPT-4.5 also add their own strengths into the mix, although GPT-4.5 isn’t a reasoning model, Claude 3.7 Sonnet is a hybrid reasoning model. Some users also really like Grok 3.

These new layers of search, research and reasoning models in 2025 are changing the interface of how we do Search. We knew 2025 was going to be excited on the search capabilities front, but it’s starting to really feel different to the internet that came before, it’s a noticeable departure from past consumer behaviors.
