Meta和xAI陷入下一代模型陷阱，OpenAI凭借Orion/GPT-4.5成功脱险
博主分析了Llama 4和Grok 4为什么翻车，以及OpenAI的Orion/GPT-4.5怎么稳住了局面，值得一看。
Google可能避开了这种“让人失望的下一代大模型陷阱”。Meta的Llama 4和xAI的Grok 4都遭遇了发布后口碑和表现未达预期的问题。
唯一没有因新模型而显著动摇领先地位的公司是OpenAI，其Orion（即GPT-4.5）成功逃脱了这一陷阱。
I assume Google escapes this trap, but this is what happened to Meta with Llama 4 and xAI post Grok 4. Only company to have escaped the "disappointing next giant model trap" without a major setback to their lead was OpenAI, with Orion/GPT-4.5.
