OpenAI has pushed back the launch of its highly anticipated GPT-5 model to focus on improving its capabilities, while confirming the imminent release of reasoning models o3 and o4-mini. This delay highlights OpenAI’s ongoing struggle to balance innovation with infrastructure capacity, as it prepares for what the company describes as “unprecedented demand” for its next-generation AI system.
The new timeline: OpenAI CEO Sam Altman revealed that GPT-5 will arrive “in a few months,” with the o3 and o4-mini reasoning models launching first, likely within weeks.
- Altman explained the delay is partly due to discovering ways to make GPT-5 “much better than we originally thought” while also encountering integration challenges.
- The company specifically cited concerns about having “enough capacity to support what we expect to be unprecedented demand” — likely referencing recent capacity issues with its 4o image generation feature.
What users can expect: When GPT-5 eventually launches, it will be available at different capability levels depending on subscription tier.
- Free users will have access to a basic version of GPT-5, according to Altman’s February announcement.
- Subscribers will access a more intelligent version, while Pro users will receive the most advanced implementation of the model.
The reasoning revolution: Altman expressed optimism about improvements to the o3 reasoning model, stating “We were able to really improve on what we previewed for o3 in many ways; I think people will be happy.”
- Unlike ChatGPT’s conversational focus, OpenAI’s o-series models are specialized for logical reasoning and complex problem-solving.
- These reasoning models, while more computationally intensive, are designed for sophisticated applications like drug discovery, coding, and scientific research.
Why this matters: The delay signals OpenAI’s recognition of infrastructure constraints following recent service disruptions and indicates the company is prioritizing system stability alongside advancing AI capabilities.
- The separate release of reasoning models suggests OpenAI is diversifying its product line to address different use cases beyond general-purpose chatbots.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
