Kun Chen(@kunchenguid):since it’s been a good day for anthropic with a strong opus 5.5 release, i’m going to highlight one more thing that may not be obvious across xai, openai and anthropic - 1. anthropic is the only provider that does not charge 2x for long context requests even at 1M context, anthropic charge at the same flat rate, while openai charges 2x above 272k tokens, and grok charges 2x above 200k 2. anthropic’s latest models have ridiculously low pricing for cached read. see chart below most coding sessions have 95%+ cache hit rate, so this difference is massive my hunch is that eventually this will even out, but for now, this is a very material difference that’s easy to overlook
