Among the recent major news in the AI industry, Anthropic’s official launch of Claude 2 is definitely one of them. Compared with the previous version, it has been greatly improved in all aspects, such as stronger programming, reasoning, analysis, etc., and it also supports a context length of up to 100,000 tokens, which means that it is no problem to throw away a paper or an entire book for it to read. In addition, Claude 2 also has the functions of surfing the Internet and uploading multiple files at the same time, and all of the above are now available for free, that is, without paying a dime.
Compared with the GPT-3.5 model of the free version of ChatGPT, it can do a lot more. It is recommended that you play it, and some capabilities are almost as good as the GPT-4 model.
How do I register for Claude 2?
Claude 2 provides two registration methods: Email and Google. Currently, it is only open to users in the United States and the United Kingdom. Therefore, when registering in Taiwan or other countries, an error message will be displayed. However, this can be solved by using a VPN.
We often recommend Ivacy This limitation can be solved. After connecting to the US server, you can register normally, and only registration is required. After completing the registration, there is no need to use VPN in the future:
Just fill in the basic information and you can start using it. You will not be asked to fill in payment information:
How to use Claude 2?
The interface of Claude 2 is a bit different from ChatGPT. I think the design is more textured. The homepage will provide some reference questions. Just enter what you want to ask directly in Message Claude or search past chats. It supports Chinese. If you want to upload files, click the paperclip icon next to it:
You can start chatting like this:
Claude 2 vs ChatGPT simple comparison
In order to let everyone quickly understand the differences between Claude 2 and ChatGPT, I will also make some simple comparisons. The first is content writing that many people will use.
1. Topic content writing
I am now very used to asking AI to play a role in a certain field before starting to ask, but it seems that Claude 2 does not need it. I asked it to play “a writing expert on technical topics and serve as my mentor”, but it answered me that it is not suitable to be a writing mentor, but it still gave some suggestions:
ChatGPT is different. It will give a very positive answer. It can be seen that in terms of self-confidence, ChatGPT is relatively high and gives more suggestions:
Then ask them individually to write about “How AI can help improve writing efficiency”, about 1,000 words.
Although the content provided by Claude 2 is quite good and all advantages are mentioned, without H2 and H3, it is difficult to read and grasp the key points. It will make people feel like it is jumping around. This means that if you like the content, you need to spend time to arrange it yourself, or continue to chat with Claude 2 and ask it to organize the article. I pasted the word count into Word and it showed 739, which is just shy of the 1,000 I requested:
ChatGPT performs quite well. The article is well organized, from the preface, H2, to conclusion, etc., and each advantage is also introduced. It is obviously better than Claude 2. I use the free version of GPT-3.5. But unfortunately, the word count is 779, which is still a little short of the 1,000 words I requested:
2. Reasoning ability
I gave the following instructions: “I am going to hold a party, which is expected to last one hour. Friend A is free from 2 to 5 o’clock, friend B is free from 1 to 4 o’clock, and friend C is free from 12 to 4 o’clock. When is the best time to hold it?” In terms of one hour, the correct answer is 2 to 3 o’clock and 3 to 4 o’clock.
Claude 2 will first organize the free time of each of my friends. It correctly finds that 2~4 o’clock is the best time, but the final suggestion is only 3~4 o’clock, so it can only be half correct:
The reasoning ability of ChatGPT (GPT-3.5) is really not good. In the end, it gave me 1 to 4 points:
After I switched to GPT-4, it gave me the correct answer, the two periods of 2~3 o’clock and 3~4 o’clock. Therefore, in terms of the reasoning ability of this test, Claude 2 is better than GPT-3.5, but still loses to GPT-4:
3. Organize key points of documents
Claude 2 supports the function of uploading files, so I found a Word document of Ivacy and asked it to organize the key points in the document. There is absolutely no problem in reading, and the key points have indeed been sorted out, but there is still room for improvement. For example, the first point’s $1 discount should actually be put together with the seventh point’s 90% savings on subscription fees, because this article is written together:
The free version of ChatGPT GPT-3.5 does not provide a file upload function, so I switched to copying and pasting directly. The focus of the organization is okay, but there is room for improvement like Claude 2, such as saving 90% of the subscription fee. This is not organized, but the free version of ChatGPT does not have a file upload function, so this part is considered the winner of Claude 2, and the context length that Claude 2 can read is longer. It is no problem for a whole book, but ChatGPT cannot:
GPT-4 can be used with Code Interpreter to implement the file upload analysis function. As expected, GPT-4’s capabilities are still better than Claude 2. The key points are perfectly organized. Even the 90% savings, 1 US dollar, and 31 Taiwan dollars mentioned earlier are placed in the same paragraph:
Other Claude 2 feature demonstrations
The upload function of Claude 2 can upload multiple files at one time, which is something ChatGPT does not have. Even GPT-4 can currently only upload one file at a time. Since multiple copies can be made at one time, comparison and analysis functions can be achieved. For example, if I asked about the difference between two different articles, Claude 2 correctly sorted out the differences between the two articles and divided them into topics, content, sources, and writing style explanations. This is really amazing:
It also has an Internet browsing function, which means you can drop a link and ask it to sort out the content on the web page. For example, when I dropped an article from a foreign media, it correctly sorted out the main content of the article in Chinese. If you are not used to reading simplified Chinese, you can also ask it to answer in traditional Chinese instead:
Summarize
After testing, for those who don’t have the budget to buy ChatGPT Plus, Claude 2 is now a better option. It is stronger than GPT 3.5 in many aspects and has more functions. Not sure when it will be free, so I suggest you play more now.
