Unveiling OpenAI's GPT 4.5: Underwhelming Performance and High Costs

Sam Witteveen's latest video delves into the long-anticipated arrival of GPT 4.5, only to find it falling short of expectations. The model, touted as OpenAI's biggest release to date, faces scrutiny for not living up to its potential as a true GPT 5. Despite claims of enhanced naturalness and conversational abilities, GPT 4.5 lags behind in benchmarks compared to its predecessors and other models in the field. The exorbitant cost of tokens further adds to the skepticism surrounding this supposed flagship model.

Witteveen's critique extends to the delayed release of GPT 4.5, with a knowledge cutoff dating back to October 2023, rendering it outdated compared to newer models. The limited output token capacity and lack of significant improvements raise doubts about the model's practicality and value for users. While some commend its creative writing output, the high price point and sluggish processing speed call into question its viability for everyday use, especially given the existence of more efficient and cost-effective alternatives in the market.

The absence of key researchers in promotional materials further contributes to the model's questionable status, leaving enthusiasts wondering about missed opportunities and unfulfilled promises. Witteveen's analysis sheds light on OpenAI's scaling efforts and utilization of low-precision training techniques, hinting at potential areas where GPT 4.5 could have excelled. However, the lack of transparency regarding system prompts and post-training details underscores the model's shortcomings and leaves room for improvement in future iterations. Overall, GPT 4.5's underwhelming performance and steep pricing raise concerns about its competitiveness in the evolving landscape of AI models.
