In the early hours of last Friday at 4 AM, GPT 4.5 officially launched. Eager and a bit sleep-deprived, I rushed to the office to experience the new model firsthand. After two days of hands-on testing, I've gathered some insights. While GPT 4.5 indeed brings impressive upgrades, the excitement just isn’t quite as electrifying as it was with GPT-4.0. Let’s dive into what this new model offers, its pricing challenges, and what it means for the future of AI.


The Dual Sides of GPT 4.5: Exciting Advances and Costly Challenges

The Good News

  • Conversational Brilliance: GPT 4.5 feels more like chatting with a thoughtful human. There were several moments where I paused in astonishment, receiving advice that was not only accurate but genuinely insightful.
  • Enhanced Performance: Early tests reveal that GPT 4.5 offers a smoother, more natural interaction. Its broader knowledge base and refined understanding of user intent make it a significant step forward in conversational AI.

The Bad News

  • Massive & Expensive: Despite its impressive capabilities, GPT 4.5 comes with a hefty price tag. OpenAI is currently grappling with GPU shortages, meaning the rollout to all user tiers is staggered. GPU limitations have forced a delayed release for many, and the high operational costs are evident.
  • Pricing Concerns: For every million tokens, the input costs a whopping \$75 and output \$150. In comparison, competitors like Claude and Deepseek offer rates that are up to 25 times lower, raising serious questions about cost-effectiveness.


Performance Upgrades: A Closer Look at GPT 4.5

GPT 4.5 doesn’t just sound smart—it is smart. Here’s what early performance benchmarks are showing:

  • Improved Accuracy: On the SimpleQA dataset, GPT 4.5 achieved a 62.5% accuracy rate, outperforming its predecessor, GPT-4.0.
  • Reduced Hallucinations: With a hallucination rate down to 37.1%, it’s clear that GPT 4.5 has a firmer grasp on factual data.
  • Advanced Learning Techniques: The model leverages unsupervised learning extensions along with innovative training methods. This results in a broader knowledge base, enhanced world understanding, and a better grasp of subtle nuances in conversations.

These technical enhancements translate into smoother creative interactions, more precise professional query responses, and an overall heightened conversational experience.

Real-World Applications and Usage

How You Can Experience GPT 4.5

  • ChatGPT Pro Users: If you're a Pro user, GPT 4.5 is already available in your model selector.
  • Rollout Plans: Plus and Team users will see the upgrade next week, followed by Enterprise and Edu tiers.
  • New Features: Enjoy support for real-time search, file and image uploads, and even a canvas for writing and coding assistance. While voice, video, and screen sharing aren’t available yet, the current feature set marks a significant leap forward.

API and Developer Tools

Developers can preview GPT 4.5 through Chat Completions API, Assistants API, and Batch API. The model even supports function calls and image input capabilities—ideal for innovative writing assistants and more. However, given its computational intensity, OpenAI is still assessing long-term API pricing and availability.


The Price Tag: Is GPT 4.5 Worth the Cost?

While the technical advancements of GPT 4.5 are clear, its pricing has sparked heated debates:

  • High Cost: At \$75 per million tokens for input and \$150 per million for output, GPT 4.5 is significantly more expensive than competitors like Claude or Deepseek.

  • Market Impact: Such steep pricing might deter cost-sensitive users. For those seeking a budget-friendly alternative, options like XXAI are already promising versions at just \$9.9 per month.

The steep cost could limit ​GPT 4.5​'s mass adoption despite its technological prowess.


User Feedback and Future Prospects

The launch of GPT 4.5 has elicited mixed reactions:

  • Disappointment Over Incremental Improvements: Many users feel that while GPT 4.5 is a solid upgrade, it lacks the "wow" factor of GPT-4.0.
  • Criticism on High Pricing: Some argue that the high costs and modest improvements amount to overhyped marketing rather than a revolutionary leap forward.
  • A Stepping Stone to the Future: Despite the criticism, there’s hope that GPT 4.5 is laying the groundwork for future breakthroughs—possibly even paving the way for GPT-5, which may finally deliver that next-level leap.

One insightful comment captured the sentiment well: while we celebrate the journey from 1 to 100, let’s never forget the groundbreaking leap from 0 to 1.


Conclusion: The Mixed Bag of GPT 4.5

GPT 4.5 offers noticeable advancements in natural language understanding, creative problem solving, and conversational nuance. However, its high operational costs and steep pricing could pose significant challenges for widespread adoption. As the AI landscape continues to evolve, GPT 4.5 might serve as a crucial stepping stone toward even more transformative innovations in the future. Whether its improvements justify the price remains to be seen, but one thing is certain: the race for smarter, more intuitive AI is far from over.
