In recent developments in the AI sector, Meta's LLaMA 3 and Microsoft's Phi-3 have been making significant strides. LLaMA 3, which was released a week ago, has seen enhancements such as an extended context window from 8K to 128K and increased inference speeds of over 800 tokens per second. Microsoft's Phi-3 is highlighted as a small yet highly capable AI model, with potential applications in 10 wild examples. Apple is also advancing in AI, focusing on developing lightweight AI models that can operate on its devices, potentially integrating these into the upcoming iOS 18. Additionally, Apple has released several small AI language models and is in discussions with OpenAI to incorporate their technology into new iPhone features.
