AI Model Showdown: November 2025 Inflection Point
In brief
- In November 2025, the landscape of large language models (LLMs) underwent a dramatic shift.
- The top model crown changed hands five times among major providers like Claude Sonnet, GPT-5.1, and Gemini 3.
- A unique test-drawing a pelican riding a bicycle-helped highlight differences in these models.
- While most agreed that Anthropic's Claude Opus 4.5 was the best for general tasks, November also marked a breakthrough in coding agents.
- OpenAI and Anthropic had been refining their models to write better code through reinforcement learning.
- This effort paid off when coding agents reached a quality threshold where they could be used reliably for real work.
- The month also saw the first commit to an obscure repository called "Warelay," which later gained traction.
- From December to January, developers explored new model capabilities and even built ambitious projects like micro-javascript-a JavaScript interpreter in Python using Pyodide and WebAssembly.
- These developments hint at a future where AI tools become more integrated into everyday workflows, pushing the boundaries of what's possible with LLMs.
Terms in this brief
- Reinforcement Learning
- A type of machine learning where models learn by performing actions and receiving feedback, similar to trial-and-error. It's used to improve decision-making in AI systems like chatbots or game-playing algorithms.
- Warelay
- An obscure repository that gained traction in November 2025, potentially related to AI developments or open-source projects. Details about its specific functions and applications are not provided in the brief.

AI Education Demand Surges
MIT Sloan Executive Education saw over 20,000 leaders attend AI courses last year. These leaders want to learn about AI basics and how to adopt the technology. Demand for AI education has grown from a basic understanding to implementing and managing the technology. Leaders are looking to understand the implications of AI on their workforce. AI education will continue to evolve as more companies adopt the technology.
AI Agents Gain New Capabilities in Self-Learning and Problem-Solving
AI agents like Claude Code, Codex, and LangChain Deep Agents have shown remarkable skills in managing tasks, chaining tools, executing code, and responding to complex queries. These advancements allow them to work more efficiently with minimal human intervention, making them valuable for developers and researchers. The integration of these AI systems into software architecture and big data schema is transforming how applications are built and maintained. By leveraging a skills repository, these agents can adapt and learn from their experiences, improving over time without constant supervision. This development could significantly reduce the time spent on repetitive tasks, allowing humans to focus on more creative and strategic work. Looking ahead, the ability of AI agents to train new sub-agents themselves opens up possibilities for even greater automation and innovation in various industries. As these technologies evolve, we can expect further improvements in how AI interacts with both data and users, making it a powerful tool for problem-solving across sectors.
Google's AI Costs Skyrocket as New Models Emerge
Google has unveiled its latest AI advancements, including Gemini 3.5 Flash, a model that outperforms its predecessor but comes at a much higher cost. Running Gemini 3.5 Flash is reported to be 5.5 times more expensive than earlier versions, and for agent tasks, costs exceed even the pricier Gemini 3.1 Pro by 75%. This trend isn’t isolated-AI expenses are rising across the board as companies invest heavily to stay competitive. At Google’s I/O developer conference, the company also introduced Gemini Omni, a multimodal model, and Gemini Spark, a personal cloud agent that runs continuously. These new offerings highlight the growing complexity and resource demands of AI development. While they promise enhanced capabilities, the steep costs may challenge developers and businesses looking to adopt them. As the industry evolves, keep an eye on how these cost increases impact innovation and accessibility in AI.
