I’m building a new PiDog v2. I have both Rpi4 and 5 at home. I want to use ChatGPT and wanted to now which Rpi would be the best choice for smooth use with ChatGPT and if Rpi5 is the best choice, how much do I need to worry about cooling the Rpi5?
I can add some heat sinks or perhaps even active color if there is enough power.
Or will it still be a smooth experience using Rpi4, perhaps Rpi5 is overkill?
I’m thinking most compute will be done at OpenAI, perhaps not much is needed from Rpi4, even with camera use and so own?
Anyone tried with ChatGPT using both Rpi4 and 5, what was the experience like?
Using ChatGPT in PiDog v2, the overall smoothness of the Raspberry Pi 5 is superior to that of the Raspberry Pi 4. However, the difference is mainly evident in local tasks and multitasking capabilities; if you’re only making OpenAI API calls, the differences are minimal. The CPU performance of the Pi 5 is approximately 2–3 times that of the Pi 4, with stronger memory bandwidth and video decoding capabilities, resulting in more stable multitasking responses.
If your primary use is the ChatGPT API, the Pi 4 is sufficient and does not require additional investment. However, if you need to balance local AI, video processing, or future expansion, the Pi 5 offers a smoother overall experience, and you need not worry about heat dissipation with active cooling.
You can start by testing API calls with the Pi 4 and then decide whether to upgrade to the Pi 5 based on your needs.
We recommend using the Pi 5 in conjunction with PiDog v2. If you are concerned about heat dissipation, you can purchase the official cooler for the Pi 5 to connect for better cooling.
Is there any recommendations on using cooling or is it overkill? I will use it with ChatGPT api. Perhaps cooling is not actually needed?
There is an active cooler from Rpi which seems to fit between rpi5 and the robot hat but if its not needed then perhaps better to do without since it will add weight and the small fan will use some small amount of power when its on.
Priority is given to not installing a radiator, with a core focus on “lightweight and low power consumption,” to maximize the flexibility and battery life of the robot kit.
If during use, the PI5 CPU temperature becomes excessively high and affects performance, consider adding a heatsink for the PI5.
