That's on OpenAI. I don’t schedule their product releases.
Since it takes several days to gather my reports on new models, we are doing our coverage of the OpenAI open weights models, GPT-OSS-20b and GPT-OSS-120b, today, after the release of GPT-5.
The bottom line is that they seem like clearly good models in their targeted reasoning domains. There are many reports of them struggling in other domains, including with tool use, and they have very little inherent world knowledge, and the safety mechanisms appear obtrusive enough that many are complaining. It's not clear what they will be used for other than distillation into Chinese models.
It is hard to tell, because open weight models need to be configured properly, and there are reports that many are doing this wrong, which could lead to clouded impressions. We will want to check back in a bit.
