This Week's Headlines: Llama 2 Released as Open Source, Available for Free Commercial Use

On July 19th, Meta collaborated with Microsoft to open-source Llama 2, a large-scale language model available in three versions: 7B, 13B, and 70B.

Llama 2 underwent training with 20 trillion tokens and supports a context length of 4k, which is twice the capacity of its predecessor. Moreover, it allows free commercial use.

Building on the success of the previous open-source community project "Llama 1," the more powerful Llama 2 is expected to lead the LLM open-source community into the 2.0 era.

Microsoft announces pricing for 365 Copilot

On July 19th, during the "Inspire 2023" conference, Microsoft announced the pricing for Microsoft 365 Copilot. The service will be offered at a rate of $30 per user per month (approximately 216 RMB) for Microsoft 365 E3, E5, Business Standard, and Business Premium customers.

Although Copilot offers powerful features, its pricing is not inexpensive. For example, for E3 subscribers and Business Standard users, this additional cost doubles or even exceeds their subscription expenses.

ChatGPT Plus has relaxed its usage restrictions and introduced a new "Custom Commands" feature

OpenAI has announced that starting from next week, ChatGPT Plus users will be able to have 50 rounds of conversation with GPT-4 every 3 hours, doubling the current limit.

Additionally, Plus subscribers can now use the "Custom Commands" feature in ChatGPT. This allows users to set background information and response styles for ChatGPT, creating a personalized "AI assistant."

The media has reported that Apple is developing Apple GPT

According to Bloomberg's report, Apple is secretly developing an AI project codenamed "Ajax," which is based on Google's Jax machine learning framework and runs on Google Cloud.

In addition, Apple is internally testing an AI chat tool based on Ajax, with the internal codename "Apple GPT."

The report further reveals that Apple is planning to launch a consumer-facing product based on this technology next year.

This week's fun news

Can't wait for the original! Readers are using ChatGPT to complete the "Game of Thrones" original work

According to IGN's report, a well-known reader, dissatisfied with the slow progress of the original author George R. R. Martin in completing "A Song of Ice and Fire" series, decided to use ChatGPT to fill in the content for the last two books of the series.

Interestingly, this reader is a programmer, and he uploaded some technical details of using ChatGPT to "write" books on GitHub. If you're interested, you can check out the process of AI "writing" there!


Research confirms it! GPT-4 has indeed become less intelligent

According to a recent paper from Stanford University and UC Berkeley, GPT-4's performance in some tasks objectively declined compared to its state in March.

The paper tested GPT-4 on 500 questions related to determining prime numbers, logic-guided instructions like "Let's think step by step," and coding abilities, finding that the results had deteriorated to some extent.

OpenAI has also taken notice of this situation and has begun investigating the matter.

Tsinghua University has launched a ChatGPT version of the game "Game Development Nation

Tsinghua University has created a "game company" called "ChatDev," where employees, from staff to bosses, are played by ChatGPT chatbots, simulating a "zero-human" game development process. This ChatDev utilizes GPT 3.5-Turbo, and despite going through design, programming, testing, and documentation processes, the game development efficiency is remarkably high. The fastest development time is less than 3 minutes, and the slowest is no more than 17 minutes, with an average development cost of only $0.2967 per game.

Although this "simulation management" AI game company is not directly applicable in practical use, it demonstrates a novel approach to using AI to simulate human society, providing valuable insights for future AI research.
