All AI chat tools will develop towards the same endpoint of being able to handle and deliver text, image, video, sound and more. It is also likely that features called 'Deep Research mode' or 'Thinking mode' will be hidden behind a very universal front end, with the AI model deciding which mode is needed according to the query. For the moment though they are explicit in the interface.
Google has sometimes been underestimated in the AI race but it has an increasing range of powerful tools. For this presentation the Gemini tool with its Deep Research function is the most relevant. NotebookLM also has powerful capabilities however - you could ask it for a Podcast on the research results and it would be very good.
Google's AI domains are thriving.

This is using a free version at gemini.google.com with a question about its Deep Research capability, which it treats as deeply as any other question.
Advanced AI Capabilities. A core differentiator lies in its advanced AI capabilities. Deep Research utilizes 'thinking models' (like Gemini 2.5 Pro and Flash) that break down complex problems into smaller, manageable steps, mimicking human-like thought processes to enhance reasoning and multi-step planning. It maintains continuity through a 1 million token context window complemented by a Retrieval-Augmented Generation (RAG) setup, allowing it to 'remember' everything learned during a session. This enables it to handle complex queries, analyze vast amounts of information, and even generate or explain code, demonstrating a significant leap in information synthesis and understanding.
Extract: Powered by the advanced Gemini 2.5 model, this capability transcends the reactive, text-centric conversational paradigms of earlier Google AI chat tools, such as LaMDA and Bard. Deep Research operates as a proactive, agentic, and multimodal research assistant, capable of autonomously executing complex research tasks from planning to comprehensive report generation. This advancement is underpinned by sophisticated architectural designs, including the Mixture-of-Experts (MoE) framework and vastly expanded context windows, coupled with enhanced reasoning capabilities that involve iterative self-critique.
Gemini took a few minutes to produce the full report comparing its Deep Research to its older versions. This is the
report in pdf form:

This is using the USD 20 per month Pro version at chatgpt.com with a question about its Deep Research capability compared to previous versions.
As with Gemini, the question is approached in the same way as a question about any other subject.
ChatGPT took just 6 minutes to produce a report comparing its Deep Research to its older versions. Below is a link to the
report in pdf form. Extract: The model reads and analyzes online texts (including articles, PDFs, and images) and pivots its search strategy based on what it finds, acting as an agent that “finds, analyzes, and synthesizes hundreds of online sources” into its answer. This allows it to handle current events and niche queries that go beyond its training data.

Though Grok does have a DeepSearch mode it is not really competitive with Gemini or ChatGPT in this area yet. It does benefit from having access to the X (Twitter) feed which provides a vast amount of real time News. A new version of Grok is due shortly.
Perplexity uses a range of AI models to power its system. It built its reputation on accuracy, with good references being provided for all listed information. It does a good job of providing multi-stage analysis and then reports on any question - and in many cases may be using OpenAI or Google provided tools behind its own user interface.
As seen below, this can include writing code to produce charts that illustrate the report.
