OpenAI release o1-pro and it costs $150 per million token input and $600 per million token output.
Currently, it’s only available to select developers — those who’ve spent at least $5 on OpenAI API services
Introducing GPT-4.5 - hallucinations down, accuracy up, non-reasoning. Rolling out to pro + api. Doesn’t look like anyone will be coding with it any time soon with this type of api pricing:
Input: $75.00 / 1M tokens
Cached input: $37.50 / 1M tokens
Output: $150.00 / 1M tokens
And then in a tweet from sama:
this isn’t a reasoning model and won’t crush benchmarks. it’s a different kind of intelligence and there’s a magic to it i haven’t felt before. really excited for people to try it!
ChatGPT Deep Research hallucinates
it claimed again to produce a complete dataset but in fact only produced ~7 lines, with a placeholder for the other ~3000.
OpenAI roadmap update for GPT-4.5 and GPT-5 from sama, which indicates that the model they’ve been cooking for some time can no longer be considered GPT-5.
We will next ship GPT-4.5, the model we called Orion internally, as our last non-chain-of-thought model.

OpenAI o3-mini released.
This model continues our track record of driving down the cost of intelligence—reducing per-token pricing by 95% since launching GPT‑4—while maintaining top-tier reasoning capabilities.
the company unveiled o3, the successor to the o1 “reasoning” model it released earlier in the year. Neither o3 nor o3-mini are widely available yet, but safety researchers can sign up for a preview for o3-mini starting today.
Elon Musk wanted an OpenAI for-profit
in 2017, Elon not only wanted, but actually created, a for-profit as OpenAI’s proposed new structure. When he didn’t get majority equity and full control, he walked away and told us we would fail.

Introducing OpenAI o1-preview, a thinking/reasoning model.
As an early model, it doesn’t yet have many of the features that make ChatGPT useful, like browsing the web for information and uploading files and images. For many common cases GPT‑4o will be more capable in the near term.
