OpenAI has begun rolling out its latest and largest AI model, GPT-4.5, to ChatGPT Plus subscribers. According to the company, ChatGPT Plus subscribers will gain access to the model gradually over the next one to three days. OpenAI CEO Sam Altman stated that initial user access will be controlled due to capacity limitations to manage expectations.
GPT-4.5 is OpenAI's largest AI model to date, trained using significantly more computational resources and data. It aims to improve performance in conversational tasks. Compared to previous versions, GPT-4.5 demonstrates superior capabilities in everyday chats, practical problem-solving, and creative tasks, potentially reducing the "hallucinations" – inaccurate answers – seen in earlier versions.
However, while GPT-4.5 shows improvements in certain areas, OpenAI acknowledges its limitations in complex reasoning, falling short of competitors like Anthropic's Claude and DeepSeek's AI models. Altman stated on social media, "GPT-4.5 is not a reasoning model and doesn't lead on benchmarks."
The cost of using GPT-4.5 is a significant concern. It costs a hefty $150 per million generated tokens, 15 times more expensive than OpenAI's popular GPT-4. This substantial price increase raises concerns about widespread adoption, especially given its shortcomings in logical reasoning and multi-step problem-solving.
Despite these limitations, GPT-4.5 remains attractive. Internal OpenAI testing shows it excels at persuading other AI models, highlighting its strong conversational abilities. Furthermore, GPT-4.5 fully supports ChatGPT tools and APIs, offering developers significant flexibility.
The launch of GPT-4.5 showcases OpenAI's ongoing exploration of balancing power, performance, and practical usability. Users eager to try the latest model will gain access over the next few days, while OpenAI continues to assess how far and fast they can push the technological boundaries.
