OpenAI's GPT-4.5 has become impractical for many developers due to its high costs compared to other models like GPT-4o. At $75 per million input tokens and $150 per million output tokens, the pricing structure discourages wide adoption. OpenAI appears to be pivoting towards simulated reasoning models such as o1 and o3, which leverage different inference methods for better efficiency. Meanwhile, competitors like Anthropic are edging ahead, suggesting that GPT-4.5 may symbolize a technological dead-end for OpenAI.
OpenAI's GPT-4.5 may be the last traditional AI model due to high costs and reduced performance, shifting focus toward more efficient simulated reasoning models.
The pricing of GPT-4.5 complicates its practicality for developers, with costs significantly higher than previous models like GPT-4o and offering diminishing returns.
Competitors like Anthropic's Claude 3.7 Sonnet are outperforming GPT-4.5, emphasizing the need for OpenAI to innovate beyond traditional LLMs.
The shift towards simulated reasoning models indicates OpenAI's recognition of limitations in scaling traditional AI models, marking a change in development strategy.
