Difference between Copilot ChatGPT via API access and official ChatGPT Mac client results

[Stakker]

Hello,

Copilot looks excellent, so I'm trying if in addition to working with Obsidian, it could replace the official ChatGPT client for general use.

I haven't followed all the AI configurations that closely recently, so sorry if this is a stupid question, but why do I get the right answer to the same question from the official client, and the wrong answer from the API in Copilot? The official client is using GPT 4-Turbo and Copilot API 4.1, but it doesn't seem to me like this should have an effect on a simple question? It looks like via the API in Copilot, ChatGPT can't access the web for up-to-date information and reference links to web pages. This could be the reason for the result, I guess. Is this a limitation in the API perhaps?

What was your question, could you show us the example side by side. Web search access is a paid feature in Copilot Plus.

Sure, the question (concerning the UI of a hardware synthesizer):

"does uno synth pro x have a power switch"

ChatGPT Client (GPT 4-Turbo, correct answer):

"The IK Multimedia UNO Synth Pro X does not have a traditional physical power switch. Instead, it powers on automatically when the power supply is connected. To manually turn the unit on or off, you can press and hold the “HOLD” button ."

"This design choice eliminates the need for a dedicated power switch, allowing for a more streamlined interface. However, it also means that the synthesizer will power on as soon as it’s connected to a power source, unless you use the “HOLD” button to control its power state."

"Additionally, upon powering on, the UNO Synth Pro X automatically initiates a tuning and calibration process. During this time, the display will show “UNO,” followed by the firmware version and a blinking “CALIBRATION” message. It’s advisable to lower your system volume during startup, as some calibration noises may be audible due to the analog signal path ."

"For optimal performance, ensure you’re using the included power supply, as the USB-C port may not provide sufficient power on its own."

And it lists 20 references on the web as the sources for this answer.

API in Copilot (GPT 4.1, doesn't know about the HOLD button, no refs):

"No, the UNO Synth Pro X does not have a dedicated physical power switch. To power it on or off, you need to connect or disconnect the power supply (USB or adapter). This is a common design choice for many compact synthesizers. If you want to avoid plugging and unplugging the cable frequently, you can use a power strip with a switch or a USB power switch as an alternative."

I am perfectly willing to pay for a great AI plugin — in fact I would prefer paying to support the development of an independent one that also respects my privacy when working with my data. I would also like to get rid of the ChatGPT client for general usage like this, but I'm not sure if this API access via Copilot is a perfect replacement.

Okay, @web prompt with Plus gave me the right answer. The answer was also much more succinct and only gave five sources. It seems to me that usually succinct is better, so I'm happy with that approach.

Bought the Believer license, because it's absolutely clear to me that Obsidian needs a fantastic AI companion, and I hope this project will have a bright future :-)
