OpenAI to Retire GPT-4.5, Its Most Advanced AI Model from API

OpenAI to Retire GPT-4.5 API Access: What You Need to Know

OpenAI announced on Monday that it will be phasing out access to its largest AI model, GPT-4.5, via its API. Released only this past February, GPT-4.5, also known by its code name Orion, has made waves in the AI community. However, developers will only have until July 14 to utilize this advanced model before they’re directed to explore alternatives.

Transitioning to GPT-4.1

In light of this decision, OpenAI will be channeling developers toward its newly launched model, GPT-4.1, which was unveiled on the same day. According to an OpenAI spokesperson, GPT-4.1 offers comparable, if not superior, performance to GPT-4.5 in critical areas, all while being more cost-effective. “We will be deprecating GPT-4.5 to prioritize building future models,” the spokesperson explained in a message to TechCrunch.

What Happens to GPT-4.5?

It’s important to clarify that while GPT-4.5 will exit the API arena, it will still be available in ChatGPT for paying customers participating in its research preview. This phase-out is primarily about streamlining resources and focusing on more sustainable AI models.

Performance and Cost Considerations

GPT-4.5 was trained using unprecedented computing power and vast amounts of data, boasting enhancements over its predecessor, GPT-4o. It improved writing capabilities and persuasiveness but surprisingly did not meet some industry benchmarks for "frontier-level" AI performance. Additionally, running GPT-4.5 is notably expensive—costing $75 for every million input tokens (approximately 750,000 words) and $150 for output tokens. This price point has raised eyebrows and contributed to OpenAI’s contemplation of GPT-4.5’s long-term viability via its API.

Why This Matters

For developers and businesses keen on leveraging AI technology, these changes bring both challenges and opportunities. The transition to GPT-4.1 not only provides a more affordable option but also invites users to engage with a model designed with future possibilities in mind.

In a world where AI continues to evolve rapidly, the decision to move away from GPT-4.5 could signify a shift toward models that balance performance with practicality— something that could be beneficial for small businesses and developers just starting their AI journey.

Final Thoughts

As OpenAI focuses its resources on cultivating the next generation of AI models, the temporary retirement of GPT-4.5 serves to remind us of the dynamic nature of technology. It opens the door for innovative solutions that could redefine how we interact with AI.
