Web Searches: Who Excels?

One of the crucial tests for any AI assistant is its ability to conduct effective web searches. To evaluate this, I asked each model to provide full specifications for the AKG N9 Hybrid headphones without specifying particular attributes.

• ChatGPT created a comprehensive and well-structured response, breaking down various specifications, including audio quality and battery life.

• Gemini provided a less organized answer that included some relevant specifications but missed others, notably the omission of specific codec support.

• Grok produced an equally robust list of specifications, going slightly beyond ChatGPT by including pricing information and availability. However, this was outside the scope of my initial request.

Winner: ChatGPT and Grok.

Providing Instructional Help

Next, I assessed how each AI would help with a practical task—replacing the ice maker in a Kenmore Elite freezer. Each assistant was given the prompt to explain the step-by-step process.

• ChatGPT provided mostly accurate steps but included incorrect instructions regarding screws and omitted a vital step of removing a plastic cover.

• Gemini mirrored ChatGPT’s performance but was slightly less clear regarding specific components.

• Grok also offered a similar quality of guidance but made different mistakes, such as referencing parts that weren’t applicable.

Here, all three performed adequately but had inaccuracies that could lead to complications.

Winner: Tie.

Image Generation

With image creation becoming increasingly integral to AI capabilities, I tested how each assistant could generate images based on specific prompts ranging from futuristic landscapes to intimate café scenes.

• ChatGPT emerged as the leader, generating high-quality images that closely followed prompts and appeared visually appealing.

• Gemini was a solid contender, but its results were not as finely tuned to the prompts.

• Grok lagged behind, struggling with both the quality and fidelity of the generated images, showing limitations indicative of an earlier generation of image synthesis.

Winner: ChatGPT.

Deep Research Functionality

To gauge the effectiveness of deep research abilities, I tasked each assistant with verifying the information contained in my headphones review. I introduced a minor, deliberate error to see if it could be detected.

• ChatGPT provided a well-organized response, listing factual claims but failed to catch the planted error.

• Gemini produced a confusing mishmash of accurate and inaccurate information, also falling short in recognizing my inserted falsehood.

• Grok exhibited a balance between thorough verification and identification of errors, though it missed the planted mistake as well.

The results were mixed, with both ChatGPT and Grok performing better than Gemini in this comparison.

Winner: ChatGPT and Grok.

Voice Interaction Quality

Assessing the naturalness of voice interactions offered important insights into user experience. Each assistant possesses unique voice capabilities.
