ChatGPT, Gemini, Claude: which is the best AI?

Two more years ago,each generative AI tried to distinguish himself with his own arguments. From now on, their functionalities tend to become more standardized. To find out if they are really the same, BDM carried out a comparison between several tools on the market, including ChatGPT and Gemini, around the same exercise: image analysis.

The media submitted three visualsa capture from Discorda graph from Ahrefs and a photo of a Pentax ME Super camera, accompanied by precise prompts, in order to evaluate the accuracy of the interpretation, the relevance of the answers and the clarity of the explanations. Objective: measure the real capacity of these AI to understand and effectively process an image

What is the best AI?

The BDM therefore compared seven tools: ChatGPT (GPT-5), Gemini, Claude, Copilot, Perplexity, DeepSeek and Le Chat in three exercises. Result : Gemini 2.5 Flash turned out to be the most interesting.

According to the BDM study, Google’s AI offers detailed and balanced analyses, particularly effective on the Ahrefs chart. She is less categorical than her competitors and enriches her answers with useful advice, particularly for the camera, without falling into overinterpretation.

Just behind, ChatGPT shines with its speed and the rigor of its explanations. It perfectly understands the Discord interface and renders the correct menus, while offering clear and structured analyses. Its only weakness noted by BDM: a minor error on the model of the camera tested.

The bottom of the ranking

Claudius 4.5 Sonnet is precise but too brief in its analyses, lacking depth in the face of complex queries. Copilot surprises with its good interpretation of Discord and Pentax, but completely misses the analysis of the Ahrefs graph, an error that BDM considers “fatal”.

Perplexity, more comfortable in research than in vision, remains clear but uneven, especially in the photo section. Finally, DeepSeek And The Cat(Mistral) bring up the rear: the first does not know how to analyze images, and the second accumulates inaccuracies.

In the end, BDM places Gemini in the lead, closely followed by ChatGPT, significantly more efficient than the rest of the panel.
