We tried this out ourselves in ChatGPT and were able to replicate similar responses.

Adding fuel to the fire is a leaked pricing sheet that mentions various GPT 4.5 models for text, audio, vision, and more. The timing also aligns with OpenAI needing to respond to recent launches from competitors like Anthropic and Stability AI.

However, we still lack official confirmation from OpenAI on any major updates to ChatGPT. It’s also possible this could be an elaborate trolling effort. And even if 4.5 Turbo exists, it remains to be seen whether the performance boost is really that significant compared to the existing model.

Comparing GPT 4.5 Turbo to Other Major Models

If the rumors of GPT 4.5 Turbo turn out to be true, how might it compare to other top conversational AI models on the market today? Here is a breakdown:


OpenAI’s GPT-4 model underpins the existing ChatGPT product. Released in early 2023, GPT-4 demonstrated stronger coherence, knowledge, and capabilities compared to GPT-3. However, some users have complained of performance downgrades in recent months. GPT 4.5 Turbo may aim to address such issues.

GPT-4 Turbo:

GPT-4 Turbo is Open AI’s latest generation conversational AI model launched in preview mode. It features a 128k context window, a knowledge cutoff of April 2023, 3x lower token costs, and 2x lower output costs compared to the original GPT-4. Early access users have noted meaningful improvements in areas like coherence and reasoning.

Claude 2.1:

Developed by Anthropic, Claude 2.1 focuses heavily on safety and reliability. Early tests indicate Claude has high levels of accuracy and responsiveness, but falls slightly behind GPT-4 on breadth of knowledge.


Launched by startup Stability AI, Gemini emphasizes creativity over safety. It produces remarkably human-like writing in stories and dialogues. However, it sometimes makes false claims or exhibits toxic behaviors requiring heavy content filtering.


A new model by Elon Musk and X (formerly known as Twitter) emphasizes knowledge and reasoning rather than text generation. Little is publicly known so far about Grok’s capabilities.

So, how might GPT 4.5 Turbo fit into this landscape based on the limited information available? Our guess is the upgrade aims to match some strengths of competitor models:

  • Improved coherence/consistency to better rival Claude
  • Faster response times to keep up with Gemini
  • Richer reasoning and knowledge like Grok’s targets

At the same time, we doubt OpenAI would risk significantly downgrading ethics or safety to pursue pure performance like Stability AI has with Gemini.

In essence, GPT 4.5 Turbo may try to balance state-of-the-art capabilities with responsible deployment better than alternatives. But until more details emerge, this is speculative.

Testing for Possible Performance Gains

For now, we recommend testing out ChatGPT and seeing if you notice any differences, especially around speed and coherence. We had some promising early results, but more systematic testing is needed.

Here are some areas where GPT 4.5 Turbo might show gains if the rumors prove accurate:

  1. Response Time: Faster response times could give it an edge over previous versions when having dialogues or asking follow-up questions.
  2. Consistency Improved: Consistency and coherence could address complaints over contradictory or nonsensical responses.
  3. Confidence: The model may “know what it knows” better rather than guessing or making up information.
  4. Creativity: Richer understanding of concepts could unlock more creative storytelling and analogies.
  5. Knowledge: A better grasp of facts and events could make it more useful for research and learning.
  6. Safety: Stronger safeguards against falsehoods, toxicity, and bias would signal responsible development.

We tested ChatGPT with questions spanning these dimensions and so far results seem promising. The responses feel snappier compared to a week ago, with greater coherence across questions. It caught itself when unsure rather than speculating. Creative narratives had a more logical flow. Facts about current events were accurate and topical.

Of course, further testing is needed by more users to confirm if these observations reflect true upgrades. It’s possible we simply got lucky with our lines of questioning or that existing GPT-4 capabilities already vary across time or prompts.

ChatGPT 4.5 Turbo – A Strategic Response to Competitors?

If genuine, the timing of GPT 4.5 Turbo’s possible release makes strategic sense amidst the burst of new AI models over 2023. OpenAI likely feels pressure to consolidate its first-mover advantage as barriers to large language models fall.

Microsoft’s $10 billion investment in OpenAI last month also sparked speculation that major model updates would follow. And the tech giant clearly has ambitions around integrating OpenAI throughout its products. New Azure supercomputing capabilities specially optimized for training transformers show how Microsoft provides the infrastructure needed for ever-larger AI.

So, while OpenAI has not publicly set a timeline for GPT-5, delivering incremental but meaningful improvements to ChatGPT makes savvy strategic sense now. Upstart competitors like Anthropic and Stability AI have shown impressive initial models. Google, Baidu, Meta, and other tech titans are all investing heavily in large language models as well, even if public launches remain months away.

Against this backdrop, GPT 4.5 Turbo could be OpenAI seizing the window to improve ChatGPT before rival services have a chance to catch up. With Microsoft’s support, it can iterate faster than academics publishing papers but avoid the risks of another giant leap like GPT-3 to GPT-4. Delivering 4.5 Turbo now when users have the most exposure to ChatGPT also lets OpenAI continue benefiting from network effects and user data.

Ethical Considerations Around Responsible Deployment

Of course, while a boost to ChatGPT would be exciting on a technology level, any upgrade poses ethical questions as well. As GPT-4 showed, the greater conversational ability also unlocks a potential for harm if misused.

Issues around research bias, toxic outputs, and misinformation remain front of mind following the public launch. And subsidized business models around digital advertising risk prioritizing engagement over user well-being.

We would hope OpenAI continues treading carefully with respect to responsible AI practices. Introducing GPT 4.5 Turbo in a limited, controlled rollout to gather more safety data would be prudent. Extending current paradigms of ethics review boards, transparency reports, and content filtering also seems sensible.

And, on the business side, one wonders if OpenAI will feel pressure to roll back some guardrails limiting harmful site usage if competitors begin encroaching on market share. With Microsoft now at the table, balancing broader access to deliver investor returns warrants monitoring.

The Path Ahead

The potential emergence of GPT 4.5 Turbo sparks both excitement at the pace of AI progress and apprehension around its societal impacts. If the next era of conversational models emphasizes competition grounded in ethics, the outcomes could be tremendously beneficial. However, if poorly deployed systems dominate usage, public trust faces risks. And, if cutting corners becomes seen as necessary for commercial success, responsible AI development could lose priority over shareholder returns.

As we await further word from OpenAI, those building the models and those integrating them must therefore ask hard questions around serving users rather than systems alone. The rumors suggest AI’s continued fast pace of evolution. But human wisdom must keep pace as well for its responsible co-evolution. The path ahead remains filled with possibilities should we navigate it deliberately and collaboratively.
