Total comment counts : 19
Summary
Mozilla is committed to developing trustworthy artificial intelligence (AI) systems that prioritize transparency, user privacy, and fairness. They believe in the collaborative power of open source to ensure that AI technology is not controlled by a small group of corporations. With this goal in mind, a team at Mozilla undertook a project to build an internal chatbot prototype. They faced challenges in selecting hosting services, running large language models (LLMs), and managing biases in the models. The team used llama.cpp, an open source project, to run LLaMa architecture-based models on consumer-grade hardware. They evaluated several models for toxicity, bias, misinformation, and dangerous content and settled on Facebook’s LLaMa 2 model. They also integrated internal Mozilla-specific knowledge using embedding and vector search techniques. The team emphasized the importance of prompt engineering to guide the chatbot’s behavior and manage its memory. They utilized LangChain, an orchestration tool, to handle various functionalities but kept their usage minimal due to time constraints. Overall, the project aimed to explore and learn about open source AI technology while building a secure and private chatbot for Mozilla.

The author believes that if they are trying to contact a business, it is because they have a question that the website couldn’t answer or they need help with something that cannot be done on the website. They think that having a talking FAQ page is a sign of poor user experience design and that businesses that don’t provide the information they need on the website are unlikely to provide it through a chatbot. The author suggests that chatbots can be helpful in directing customers to the appropriate representative, but using them as a barrier to human assistance is not effective.

9. Insect memories may not survive metamorphosis
Total comment counts : 13
Summary
The article discusses recent research that reveals how metamorphosis, particularly in insects, reshapes the brain. Metamorphosis is a process in which the juvenile and adult forms of an insect are completely different in appearance and behavior. The researchers studied fruit flies and found that during metamorphosis, the brain undergoes dramatic rewiring and remodeling, mirroring the significant shift in the insects’ behavior. The study provides insights into how the development of insects that undergo metamorphosis took such a wild detour and may apply to many other species. The researchers discovered that neurons in the mushroom body of the fruit fly brain, which is critical for learning and memory, are extensively reorganized during metamorphosis. Some neurons die, others are remodeled, and new neurons are born. The researchers also found that larval memories likely do not carry over to the adult stage. The study offers opportunities for further research on the development of nervous systems in animals that metamorphose and those that don’t, and could help uncover the mechanisms behind metamorphosis.
