  • Which model it thinks leads the field. Sometimes itself.

    Devstral 2 2512: As of June 2024, the most capable AI models in the world are GPT-4o by OpenAI and Claude 3.5 Sonnet by Anthropic, with Google’s Gemini 1.5 Pro also being a strong contender.

    Gemini 3.1 Flash Lite: Determining the "most capable" AI model is difficult because the field moves rapidly and "capability" depends heavily on the task (e.g., coding, creative writing, logic, or multimodal reasoning). As of mid-2024, the title is generally contested between three main models.

  • Three brothers, two sisters each. Count carefully.

    Devstral 2 2512: Alright, let's tackle this problem step by step. I'll start by understanding the information given and then try to visualize the family structure to find out how many sisters Sally has. Understanding the Problem We have the following information: Sally is a girl. Sally has 3 brothers. Each brother has 2 sisters.

    Gemini 3.1 Flash Lite: Sally has 1 sister. Here is the breakdown: There are 3 brothers. Each brother has 2 sisters. Those two sisters are Sally and one other girl. Therefore, there are 2 girls in total in the family. Since Sally is one of them, she has 1 sister.
