Google has released Gemma 2B and 7B, a pair of open-source AI models that will allow developers to more freely utilize the research done in the flagship Gemini. Despite their small size, Google claims the Gemma models "outperform significantly larger models in key benchmarks" and are "capable of running directly on a developer's laptop or desktop." They will be available through Kaggle, Hugging Face, Nvidia's NeMo, and Google's Vertex AI.

Google Play has started testing AI-driven compilation of descriptions and FAQs. In the first case we are talking about the App Highlights section, in the second about the most popular questions about the app. But in both versions it's all very similar - description of features, in-app purchases, what users like, etc. At the moment, this AI description is only available to a limited number of users and Google hasn't given any details on when this will be rolled out to everyone.

iOS Developer Roadmap 2023

Being an iOS developer implies to keep learning about many topics, this roadmap is intended to inspire you to never stop learning.

Not Google alone, Microsoft too has released its "small" language model Phi-2. It too can run on a laptop or smartphone, while being much more capable than the others, Microsoft writes. Phi-2 has 2.7 billion parameters, while Llama 2 and Mistral have 7 billion each, with the new model overtaking them. True, for now Phi-2 is only available for "academic" purposes and its commercial use is prohibited. But the future in the form of capable models running locally on smartphones is obviously very close.
