Artificial intelligence development continues to accelerate as leading companies race to deploy increasingly sophisticated models. The latest advancement comes from a major player in the AI space, who has just unveiled their newest language model while simultaneously revealing infrastructure challenges that highlight the growing demands of cutting-edge AI technology.
GPT-4.5 Makes Its Debut
OpenAI has officially unveiled GPT-4.5, its newest and most advanced AI model to date. According to research lead Mia Glaese, the model is initially available as a research preview to ChatGPT Pro users (the USD $200/month tier) and developers through the API. The company plans to expand access to ChatGPT Plus subscribers (USD $20/month) starting next week, though the rollout is being staggered due to infrastructure constraints.
Enhanced Capabilities
The new model brings significant improvements in several key areas. OpenAI claims GPT-4.5 is their most knowledgeable model yet, with particular advancements in unsupervised learning and reasoning capabilities. Users can expect enhanced performance when handling science-related queries, improved word knowledge and intuition, and a reduction in hallucinations – instances where the AI generates completely fabricated or inaccurate information.

Emotional Intelligence Breakthrough
Perhaps most notably, GPT-4.5 represents a significant step forward in emotional intelligence. In demonstration comparisons against previous models, the new system showed a markedly improved ability to pick up on social cues in conversations involving personal situations. For example, when responding to a scenario about a friend canceling plans, GPT-4.5 offered both emotionally charged and measured responses that felt more natural and human-like. OpenAI reports that testers consistently ranked the new model higher in emotional intelligence compared to its predecessors.
Multilingual Improvements
Another significant enhancement comes in multilingual processing. GPT-4.5 reportedly outperforms previous iterations when working with languages other than English, making the technology more accessible and useful to non-English speakers worldwide. This improvement aligns with the broader industry trend toward developing more globally inclusive AI systems.
Infrastructure Challenges
Despite the technological advances, OpenAI CEO Sam Altman has acknowledged significant infrastructure challenges affecting the rollout. Recent weeks have seen ChatGPT users experiencing slower response times, which Altman attributes to a shortage of GPU processing power amid surging platform growth. He described GPT-4.5 as a giant, expensive model that requires substantial computational resources to run effectively.
Scaling Up Hardware
To address these limitations, OpenAI is rapidly expanding its infrastructure. Altman revealed that tens of thousands of GPUs are scheduled for installation next week, which should enable the company to complete the rollout to Plus subscribers. Looking further ahead, hundreds of thousands of additional GPUs are on order, though Altman expressed confidence that user demand will continue to push the limits of even this expanded capacity.
Long-Term Solutions
The GPU shortage has highlighted OpenAI's dependence on third-party hardware manufacturers, particularly Nvidia. In response, the company has reportedly been exploring chip development partnerships, including discussions with Broadcom. According to industry insiders, OpenAI is preparing to send a custom chip design to TSMC for validation in the coming months, with potential mass production beginning in 2026 if all goes well.
User Experience and Pricing
For end users, the most noticeable changes with GPT-4.5 will be its more natural, conversational approach to answering questions and enhanced emotional intelligence. While the model is currently restricted to the Pro tier, the eventual rollout to Plus users will bring these improvements to a broader audience. Free tier users will continue to have access to GPT-4o mini, which remains sufficient for many casual use cases.
Future Outlook
While Altman cautioned that GPT-4.5 is not a reasoning model and may not dramatically improve benchmark scores, he expressed genuine enthusiasm about the quality of interaction it provides. It is the first model that feels like talking to a thoughtful person to me, Altman noted, adding that he has been astonished at getting actually good advice from an AI during his interactions with the system.
