This, my guess is OpenAI wised up after r1 and put safeguards in place for o3 that it didn't have for o1, hence the delay.

I think that's unlikely.

DeepSeek-R1 0528 performs almost as well as o3 in AI quality benchmarks. So, either OpenAI didn't restrict access, DeepSeek wasn't using OpenAI's output, or using OpenAI's output doesn't have a material impact in DeepSeek's performance.

almost as well as o3? kind of like gemini 2.5? I dug deeper and surprise surprise: https://techcrunch.com/2025/06/03/deepseek-may-have-used-goo...

I am not at all surprised, the CCP views AI race as absolutely critical for their own survival...

The benchmarks are not reflective of real world use case. This is why OpenAI dominates B2B. As a business, its in your best interest to save money without sacrificing quality.

"Follow the money."

Businesses are pouring money into the OpenAI API. This is your biggest clue.
