OpenAI’s GPT-4.5 AI model comes to more ChatGPT users
OpenAI has started rolling out its latest AI model, GPT-4.5, to ChatGPT Plus subscribers. The model boasts improved world knowledge and emotional intelligence but has high operational costs. Despite being large, it trails behind other models in performance. OpenAI is adjusting rate limits based on demand and assessing the model's long-term availability due to its high cost.
Key points
- OpenAI rolls out GPT-4.5 to ChatGPT Plus users over '1-3 days'.
- GPT-4.5 is the largest AI model from OpenAI, trained with more data and compute power.
- GPT-4.5 has improved emotional intelligence and lower hallucination rates.
- Despite its size, GPT-4.5 does not outperform some competing models from other AI companies.
- Running GPT-4.5 is expensive, prompting OpenAI to evaluate its API viability.
- Costs for using GPT-4.5 are significantly higher than GPT-4, affecting accessibility.
Why it matters
- The rollout of GPT-4.5 aligns with the increasing demand for large language models.
- Current competition in AI is intensifying with emerging models from DeepSeek and Anthropic.
- High operational costs of AI models may affect future accessibility and development trends.
- The trend towards AI models with improved reasoning capabilities reflects broader IT advancements in AI development.
OpenAI's rollout of GPT-4.5 highlights ongoing competition in AI and the balance between model improvements and operational costs, raising questions about the future of large language models in accessible applications.
