Using Opus 4.8 on their Max 5x plan (108 EUR with VAT) would have cost me around 4600 EUR at API rates: https://news.ycombinator.com/item?id=48684539

I also compared them against GLM Coding Plan (cause everyone was positive of the model): https://blog.kronis.dev/blog/z-ai-s-glm-5-2-is-a-great-model... and Anthropic still gives you a bit more tokens despite having some of the presumably most expensive to train and run models.
