OpenAI seems marginally better. they did release gpt-oss-120b, which was decent at the time. but certainly not much better, and they seemed even more on board with fully disabling guardrails for Uncle Sam than Anthropic was. then again, rumor has it that Anthropic's AI selected that Iranian elementary school as part of Palantir's Project Maven pipeline, so..

I strongly recommend open-weight wherever you can. assume any data you pass to a closed model (including opinions or political positions you intimate) will be retained and analyzed in unfriendly ways, either now or ten years from now.
