Sam Altman reveals OpenAI’s plans for GPT-4.5, GPT-5

Key Points 

• OpenAI will release GPT-4.5 soon, followed by GPT-5, which integrates multiple technologies, including o3.

• OpenAI plans to simplify its product lineup and provide unlimited GPT-5 access at a standard intelligence level.

♨️News – OpenAI CEO Sam Altman has shared new details about the company’s AI roadmap, confirming plans for GPT-4.5 and GPT-5 in a post on X. He also acknowledged that OpenAI’s product lineup has become more complex than intended and said the company is working to simplify things. 

👨🏻‍💻What to expect – OpenAI plans to release GPT-4.5 in the coming weeks. Internally called Orion, it will be the company’s “last non-chain-of-thought model,” meaning it won’t have the advanced reasoning capabilities seen in models like o3. 

Following that, GPT-5 will bring together multiple OpenAI technologies, including o3, into ChatGPT and its API. Because of this shift, o3 will no longer be launched as a standalone model. Altman described GPT-5 as a step toward unifying OpenAI’s models so they can better decide when to think more deeply or respond quickly, depending on the task. He also confirmed that GPT-5 will incorporate features like voice, canvas, search, and deep research.  

Once GPT-5 is widely available, OpenAI plans to offer unlimited chat access at a standard intelligence level, with higher intelligence tiers available for ChatGPT Plus and Pro subscribers.

OpenAI overhauls model spec to shape its AI’s future behavior

Key Points 

• OpenAI’s updated model spec focuses on customizability, transparency, and “intellectual freedom.”

• The new guidelines encourage AI models to engage in controversial topics thoughtfully rather than avoid them entirely.

🤓News - OpenAI has significantly expanded its Model Spec—the document that defines how its AI models should behave—and is making it free for anyone to use or adapt.  

✨What’s changing? The updated spec covers everything from handling controversial topics to user customization. It’s built around three key principles: customizability, transparency, and what OpenAI calls “intellectual freedom,” meaning users should be able to explore and debate ideas without unnecessary restrictions.  

The document also reflects ongoing AI ethics debates, reinforcing rules against reproducing copyrighted content or bypassing paywalls. It explicitly bans encouraging self-harm—a topic that drew attention after a teen’s tragic death following interactions with a chatbot on Character AI.  

One major shift is in how the models approach sensitive topics. Instead of avoiding them altogether, the goal is to “seek the truth together” with users while maintaining clear ethical boundaries. This approach follows criticism from figures like David Sacks, who accused ChatGPT of political bias. The spec also hints at a possible “grown-up mode” in response to user feedback, allowing some mature content while keeping strict bans on harmful material.  

Other updates focus on reducing AI’s tendency to be overly agreeable, ensuring it provides constructive feedback rather than just going along with users. OpenAI has also clarified a hierarchy for how different rules influence AI behavior, with platform-level policies taking priority over developer and user preferences.  

🌟Note - These updates won’t immediately change how ChatGPT works, but OpenAI says they’re a step toward making its models more consistent. The company is also open-sourcing its model evaluation prompts to encourage transparency.
