Artificial intelligence leader OpenAI has officially launched GPT-4.5, its most powerful and sophisticated chatbot model to date. OpenAI CEO Sam Altman described GPT-4.5 as a “giant” and “expensive” upgrade, emphasizing its ability to engage users with a more natural and human-like conversational experience.

Currently, GPT-4.5 is available exclusively to ChatGPT Pro subscribers, with broader access expected in the near future. So, what makes GPT-4.5 different from previous models? Here’s a breakdown of its key features, capabilities, and availability.

Key features of GPT-4.5: What’s new?

  • More Knowledgeable & Intuitive
    GPT-4.5 is OpenAI’s most knowledgeable model yet, offering enhanced contextual awareness, better problem-solving skills, and superior writing and coding capabilities.
  • Improved Emotional Intelligence
    The model is designed to better understand emotions and nuances, making conversations more natural and human-like.
  • Fewer AI “Hallucinations”
    One of the biggest improvements in GPT-4.5 is its reduced tendency to generate inaccurate or misleading responses, a common issue in previous AI models.
  • Higher Computational Efficiency
    GPT-4.5 is 10 times more efficient than its predecessor, GPT-4, meaning it processes information faster while using fewer resources.

How does GPT-4.5 compare to other AI models?

GPT-4.5’s launch marks a significant leap in AI technology, placing OpenAI ahead of competitors like xAI and Anthropic.

  • OpenAI: Expected to reach a $340 billion valuation after its upcoming funding round.
  • xAI (Elon Musk’s AI company): Valued at $50 billion.
  • Anthropic (Amazon-backed AI firm): Currently valued at $18 billion, with potential funding to push it to $60 billion.

These figures highlight OpenAI’s dominance in the AI sector, as GPT-4.5 sets a new standard for chatbot intelligence and efficiency
