GPT Image 1.5 replaces the old DALL·E workflows and becomes OpenAI’s default image system, accessible via ChatGPT and the API. The model incorporates advanced moderation controls configurable via the API, allowing developers to balance security and creative freedom.
In parallel, GPT-5.2, launched in early December 2025, improves upon GPT-5 with faster responses, better contextual understanding, and enhanced reasoning capabilities. On the SWE-bench verified benchmark (coding), GPT-5.2 achieves 78% accuracy.
OpenAI and Disney: a historic partnership
An unprecedented strategic alliance
The announcement that shook Hollywood: on December 16, 2025, The Walt Disney Company and OpenAI concluded a content licensing agreement for a duration of three years. Disney becomes the first major content licensing partner on Sora, OpenAI’s video generation platform.
As part of this historic agreement:
- Sora will be able to generate short videos based on more than 200 Disney animated characters from Disney, Marvel, Pixar, and Star Wars
- Users will be able to create content with iconic costumes, accessories, vehicles, and environments
- ChatGPT Images will have access to the same intellectual property for image generation
- A selection of videos created by fans will be available for streaming on Disney+ in early 2026
A one billion dollar investment
Disney is investing 1 billion dollars in OpenAI, thus consolidating its commitment to generative AI. Robert A. Iger, CEO of Disney, states: “Technological innovation has continually shaped the evolution of entertainment. Through this collaboration with OpenAI, we will thoughtfully and responsibly extend the reach of our storytelling through generative AI”.
This alliance marks a turning point in the entertainment industry’s recognition of AI and establishes standards for responsible AI use in this sector.
Autonomous agents become reality
Gemini Agent: the assistant that acts for you
On December 19, 2025, Google unveiled Gemini Agent, an experimental feature that manages multi-step tasks directly in the Gemini app. Powered by the advanced reasoning of Gemini 3, the agent can:
- Connect to your Google applications (Gmail, Calendar, Drive)
- Organize your inbox
- Plan complex trips
- Perform in-depth research with Deep Research
- Navigate the web in real time
The user remains in control: Gemini Agent asks for confirmation before critical actions such as purchases or sending messages. Initially available to Google AI Ultra subscribers in the United States, this tool marks “our next step toward a true generalist agent”, according to Google.
OpenAI Atlas: the AI browser
To counter Comet from Perplexity AI and Google Search’s AI mode, OpenAI has launched its AI-powered browser: Atlas. This agentic and interactive browser can:
- Perform multi-step actions
- Manage online shopping
- Conduct in-depth research
- Remember previous searches thanks to its “Memory” function
The Atlas browser illustrates OpenAI’s vision for AI agents capable of navigating and interacting with the web autonomously while remaining under human supervision.
The Agentic AI Foundation
In December 2025, OpenAI, Anthropic, and Block co-founded the Agentic AI Foundation (AAIF) under the Linux Foundation. This initiative aims to establish open standards for AI agents, with the AGENTS.md standard (already adopted by more than 60,000 projects).
The goal: ensure interoperability of AI tools from different vendors and prevent technology lock-in, crucial for SMEs and enterprises.
