Key claims and evidence
Key claims in source A
- The news of GPT-4o's end was first announced in a post on the OpenAI website in January, but the discontinuation also included GPT-5, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini from ChatGPT.
- This time around, OpenAI doesn't seem very open to preserving access to GPT-4o, especially since it'll serve only a small portion of the user base.
- Some users are mourning GPT-4o's discontinuation on February 13, despite the concerns that the cult-favorite model was dangerously sycophantic.
- OpenAI OpenAI's GPT-4o may have survived its first brush with going offline, but it won't be as lucky this time.
Key claims in source B
- Unlike Claude Mythos Preview, which Anthropic said is an entirely new model, OpenAI's GPT-5.4-Cyber is a fine-tuned version of its existing GPT-5.4 large language model.
- That was the logic behind Anthropic's Project Glasswing, announced last week.
- Instead, the company is doing a limited release to verified cybersecurity testers, according to a blog post shared on Tuesday.
- OpenAI uses the feedback from these testers for "understanding the differentiated benefits and risks of specific models, improving resilience to jailbreaks and other adversarial attacks, and improving defensive capabili…
