Retrieval Augmented Generation (RAG) helps large language models (LLMs) answer questions using up-to-date or private information by connecting them to external data sources, unlike fine-tuning which retrains the model on specific data. RAG is useful when you need current, dynamic information without costly retraining, making it ideal for tasks like customer support or knowledge management. Fine-tuning is better for deep expertise in a specialized field but requires more data and effort. Using RAG lets you get accurate, relevant answers quickly by combining the model’s language skills with fresh, specific data, improving usefulness and reliability.

🌍 Cities often create "urban heat islands," where temperatures are higher than surrounding areas due to concrete, asphalt, and less greenery. This effect can raise cities’ temperatures by several degrees. ✨

🪐 Uranus stands out as the coldest giant planet in the solar system, with atmospheric temperatures dipping as low as minus 224 degrees Celsius—colder than even Neptune, despite being closer to the Sun. This frigid world is also tipped on its side, with its axis tilted by about 98 degrees, so its poles almost point directly at the Sun during parts of its long, 84-year orbit. ✨

The temperature -40 °C is the same as -40 °F. This is the only temperature where Celsius and Fahrenheit match exactly. 🌡️❄️
