Comparison of the smartest AI models and tools

Last updated April 9.

This is my comparison of  AI models and tools that are considered to be on a similar level as ChatGPT GPT-4, which has been considered the gold standard since it was launched in March of 2023. Only recently have other companies than OpenAI released AI models that have similar levels of intelligence as GPT-4. 

Short version: GPT4 is still best because of all the functions beyond just text in and out, but I find myself using Claude 3 and Gemini 1.5 almost as much.

Note that if you use the free ChatGPT you are not using GPT-4, but the much weaker GPT 3.5. You really shouldn’t! If you insist on only using free versions of AI you should use Claude 3 and Gemini 1.5 (while it is still free), or at least Microsoft Copilot.

Conclusion Still best overall, but the small context window is a serious limitation. Still surprisingly underwhelming. Can use Google Search to confirm output. Google also has NotebookLM that works with several very large documents Surprisingly good! Will hopefully get some customization options soon. The free version is very good too. The best of these for tasks that involve searching for information from websites etc. Now runs a better version of GPT4 than ChatGPT. Very good free version. Appears to be a great choice when mainly looking for a conversation partner and not help with complex tasks. Free! Significantly better than Gemini 1 Ultra and the 1M token context window is amazing. For now it is even free!


Context Window: The amount of data the AI model can work with at the same time, you can think of it as short term memory. More is better!

Tokens: AI models break down words into smaller parts called tokens. A rule of thumb is that 1000 tokens is around 750 words.

Internet Access: Some AI models can access data from the Internet for you while others can’t. Microsoft Copilot is the best of the tools in this table at this, but if your main purpose is searching for something online I recommend using Perplexity.AI.

Customization: You can give some AI tools information you always want it to have, for example what you do and what your main interests are.

Code Execution: The ability for an AI tool to use another tool to execute code to do things for you.

Knowledge Cutoff Date: Anything that has happened after this date is unknown to the AI model unless you inform it or it can access the Internet.
