Yep this is what caused me to switch to Anthropic from OpenAI a few months back, couldn't use any model newer than GPT-4 even if I paid for credits, unless I did a biometric check. I guess I'll move to perplexity or deepseek or something if anthropic flags me for the same.

GLM-5.2 has been very good

The cost on Deepseek is so low, it's no wonder it's the top on open router. You can even use it from other vendors like cloudflare.
