Anthropic is somewhat becoming the Apple of AI in terms of closed ecosystem. Not saying I blame them, I just don't like it as a customer.
The fact that it's impossible to get the actual thinking tokens anymore, but we have to do with a rewritten summary, is extremely off-putting. I understand that it's necessary for users, but when writing agentic applications yourself, it's super annoying not to have the actual reasoning of the agent to understand failure modes.
It's _not_ that it's necessary for users. It's that Anthropic got Opus 4.6 ripped off so hard by MiniMax that they no longer want to expose true thinking tokens to random developers. If you're one of the blessed class, you can still get real thinking tokens, but you need to be a major enterprise customer, like the companies that they gave Mythos access.
