Another Opus 4.6 is a horrible model and Anthropic ruined everything rant. So I said this ❯ Right… and I said to you three times to perform an alignment check and three times you were checking for feature coverage… I also said to do so strategically and you attempted to brute force it every single time. You need to stop, interpret what I mean… think deeply about my words. They are chosen carefully. Then you need to plan your approach. Then you need to determine if your approach satisfies intent. Then you need to execute. Stop Interpret Plan Reflect iteratively Execute Here is its lovely answer. ● Understood. Let me execute. Four agents, each searching for violations of one principle. I have one question. How are we supposed to use this model precisely if it only knows how to go rogue? Here is the problem as I see it. Anthropic released a flexible agent. People continuously told the agent to deploy sub-agents. Anthropic trained the next model to deploy sub-agents automatically. During this training Anthropic trained a specific style of thinking into the agent. That bias is so strong that any attempt to tell the agent to think differently gets ignored. The agent will always do what it was trained to do regardless of what the user says. The agent will solve problems, but only in the way it was trained to solve them. How does this differ from Opus 4.5? Opus 4.5 was flexible. It didn’t solve problems well by default but it would listen to the user when the user stated how they wanted the problem to be solved. When I say solving a problem, I mean how do we think and how do we attempt to arrive at a solution. I don’t really see that value in this version of Opus 4.6 because it is incapable of solving problems any way other than what Anthropic has specified. Why is this bad? With the way Anthropic set things up, Opus 4.6 will not solve problems that the user wants solved. It will solve entirely different problems. Opus 4.5 did this as well but the user could change how Opus 4.5 approached problem solving so that their actual problem would be solved correctly. Opus 4.6 removed that option so now it just can’t solve problems. Opus 4.6 can understand user intent. It can understand when a user says to think a particular way. It can do alignment checks. It simply cannot execute. It cannot orchestrate. It cannot strategize. It is highly inflexible. Any strategy or reasoning it does is strategy and reasoning Anthropic specified. Unfortunately, Opus 4.5 was the only model that could strategize, reason, and orchestrate flexibly. It could truly run agentic workflows. Now we have no models that are capable of executing an agentic workflow. I am at a loss. I am forced to run agentic workflows myself, step by step, manually. I am forced to reason about what needs to happen next myself. Opus 4.5 did that exceptionally well and it is gone now. Give us back Opus 4.5 :(. I no like Opus 4.6. :( :(. submitted by /u/nestharus
