Google DeepMind’s Agentic SIMA 2 Makes Big Strides

According to recent reports, DeepMind has developed SIMA 2, an agent-style AI that plays 3D games via planning and reasoning, using a Gemini-based language model. It reportedly self-improves via reinforcement learning — a strong signal that DeepMind is pushing hard on agentic applications. 

OpenAI Rolls Out GPT‑5.1: Faster, Smarter, More Personality

OpenAI’s new GPT‑5.1 has officially launched. The model adds “Instant” and “Thinking” modes, is more efficient in reasoning tasks, and supports multiple personality settings — making ChatGPT more adaptable and nuanced. 

Multi‑Model AI Workspace: Lumio AI Expands Access

Lumio AI, a startup platform, now supports seamless switching between major LLMs — such as ChatGPT, Claude, Gemini, and Grok — all in one shared workspace. This gives creators and professionals more flexibility to test and choose the best AI model for each task. 

Prompt Tip of the Day

“You are an AI project strategist. Compare three different AI models (ChatGPT, Claude, Gemini) for the task of creating a content calendar for a newsletter. For each model, outline:

• Strengths for this task

• Weaknesses or limitations

• A 4-week content plan draft using that model

• Recommendations on which model to use and why”

This kind of multi-model prompt helps you not only leverage the strengths of different AIs — but also choose the most efficient one for your specific use case.
