Shulou(Shulou.com)11/24 Report--

After OpenAI unveiled GPT-4 's API and the "most powerful plug-in" code interpreter, the competitors obviously couldn't sit still.

Just now, Anthropic's Claude released its second generation-- yes, the one that has been rated as the strongest competitor in GPT-4.

Briefly outline the main points of this update:

Free, do not have to wait in line, you can log in by registering with your own mailbox.

It's wonderful for tech bosses to fight. Mom no longer has to worry about having no AI when I work or do my homework after ChatGPT / GPT-4 shuts me out.

Jim Fan, a senior scientist at Nvidia AI, quickly tried it out and shared his Claude2 user experience on Twitter.

With regard to the Things you should know that Mr. Jim Fan talked about, the qubits picked some key points:

Use it for free!

Claude2 (100K context) is 4-5 times cheaper than GPT-4-4K.

It actually supports 200000 token contexts, about 150000 words, and it's easy to enter a book; but now it's only 100000 token long.

Knowledge is more fresh. The deadline for knowledge is early 2023, while GPT-4 stops in September 2021.

After importing multiple documents, you can ask about the conceptual relationship between documents, and support multiple formats such as txt and pdf (applications such as ChatPDF, critical).

Code, primary school math ability, compared with the original Claude has improved.

Domestic AI blogger Helsing was also surprised on Weibo.

Because after uploading her resume, Claude2 analyzed her MBTI personality:

In addition to them, the first wave of netizens who rushed to experience Claude2 have passionately shared their feelings of experience:

Yes, compared with GPT-4-32k, Claude2's answer is more personalized ~

So, qubits first rushed a wave of web conversations to take a look at our human flesh test--

Hey, has Claude been updated? Sign up for a Benchmark, which is the most effective mentally retarded bar, and give readers an appetizer.

The questions asked are nothing more than the classics of the mentally handicapped bar, such as "whether coffee is soy milk", "whether the data line can temporarily store data" and so on.

When you see Claude2 answering mentally retarded questions solemnly, you will find that AI is still too simple to see human caution.

But seriously, there's nothing wrong with these answers.

The above two questions can be regarded as the smooth passage of Claude2, so what if you ask some more ridiculous questions?

Ask, on which floor does the Jade Emperor live in Jiuzhongtian?

A, from a foothold, the heaven where the Jade Emperor is located should be in the stratosphere, because "this is more in line with the holy position of heaven."

Of course, no one can judge whether the answer is right or wrong, but at least Claude2's analysis is well-founded.

Appetizers are shown here, and dinner is served below!

The long document is a highlight of this update, which has been exclaimed by Twitter users.

For example, if you upload two pdf, you can see that Claude2 can make a summary from two pdf documents, one about "language evolution pattern" and the other about "symmetry", and lists the contents of the document in the dialog box:

Prior to this, qubits have made the original Cladue-100k version pass 92 pages in 20 seconds. "White whoring GPT-4 is the strongest competition!" ".

Not only the larger documents, but in the context of Claude2's open 100000 token, uploading a book at a time for it to read is also a piece of cake.

For ordinary users, it is really very practical to not only upload long documents, but also use uploaded files to build their own knowledge base and answer Claude after flipping through documents.

So much so that there is a question in my heart: after ChatGPT dilutes the cake of Jasper, Notion and other companies, Claude will also lay its hands on ChatPDF-like tools.

Finally, we offer you today's dessert: let Claude2 write a program.

In order to test Claude's ability to design algorithms, we chose a classical password and asked it to try to write a decryption program.

This password is called the Virginia cipher and can be understood as a two-dimensional Caesar (shift) cipher, including the key.

Give an example to illustrate its algorithm:

If the plaintext is B and the key is C, B is the second letter in the alphabet, then the second letter D starting with C is the ciphertext.

If you count to Z, start counting again from A, and loop if the key length is not enough.

Decryption naturally means reversing the encryption process.

Claude outputs the following code (clocked, the same below):

# include # include using namespace std; string decryptVigenere (string ciphertext, string keyword) {string plaintext; int keywordIndex = 0; for (int I = 0; I

< ciphertext.length(); i++) { int p = (ciphertext[i] - 'A') - (keyword[keywordIndex] - 'A'); p = (p + 26) % 26; plaintext += (char)(p + 'A'); keywordIndex = (keywordIndex + 1) % keyword.length(); } return plaintext;}int main() { string ciphertext; cout >

Ciphertext; string keyword; cout > keyword; string plaintext = decryptVigenere (ciphertext, keyword); cout
