I’m using to study and doing research. Now I’m avoiding GPT5 for research as it’s creating so many security blocks that is just much easier to use another model. If I ask a protocol, like, how much RPM should I set in the centrifuge to separate human cells. It replied that for safety reasons, cannot answer the question. Something that is public available and documented. It happens so often that is just better to just don’t use.
On 4o it works well.
