OpenAI has launched GPT 4.5, its most advanced AI model to date, which is currently available for ChatGPT Pro users and API developers, with broader access planned for Plus, Team, and EDU users next week.

The new model enhances performance through improved unsupervised learning, resulting in fewer hallucinations and a more natural tone in responses.

Despite these advancements, CEO Sam Altman cautioned that GPT-4.5 is not designed as a reasoning model and will not dominate benchmark tests, focusing instead on qualitative improvements.

Concerns have arisen regarding OpenAI's sustainability, particularly due to a high burn rate and Microsoft's recent scaling back of AI commitments.

The launch occurs amid scrutiny of AI scaling laws, with worries about reaching a performance plateau as model size and data increase, alongside rising development costs.

OpenAI introduced the 'Deep Research System Card,' detailing safety measures like external red teaming and risk assessments for its AI tools, emphasizing privacy protections.

Early reviews from AI experts are mixed; while some praise the model's creativity, others find it underwhelming and expensive.

Looking ahead, OpenAI plans to enhance explicit reasoning in future models, aiming to improve AI's ability to tackle complex problems, especially in STEM fields.

Competitors like xAI’s Grok 3 and Anthropic's Claude 3.7 Sonnet are closing the performance gap, prompting OpenAI to focus on user retention and continuous innovation.

The launch signifies a significant step for OpenAI, which is reportedly in discussions for a $40 billion funding round that could elevate its valuation to $340 billion.

Industry analysts predict the AI market could reach $190 billion by 2025, driven by advancements in natural language processing and AI's integration across various sectors.

The evolution from generalized superintelligence to specialized AI reflects a trend where models are tailored for specific tasks rather than attempting to excel in all areas.
