I’m always fascinated by the fine-tuning of LLM personalities. Might we finally get less of the reflexive “You’re absolutely right” with this one? Maybe we’re entering the Emo Claude era. Per the system card: In 250k real conversations, Claude Sonnet 4.5 expressed happiness about half as often as Claude 4, though distress remained steady.

I like being lightly flattered.

Anecdotal evidence. I have a fairly large web application with ~200k LoC. Gave the same prompt to Sonnet 4.5 (Claude Code) and GPT-5-Codex (Codex CLI). "implement a fuzzy search for conversations and reports either when selecting "Go to Conversation" or "Go to Report" and typing the title or when the user types in the title in the main input field, and none of the standard elements match, a search starts with a 2s de…

I had similar experience, not good enough yet to come back for the Claude max plan.

Sticking with ChatGPT pro sub and gpt5 codex on high.

I personally enjoy the “You’re absolutely right!” exclamation. It signals alignment with my feedback in a consistent manner.

You’re overlooking the fact that it still says that when you are, in reality, absolutely wrong .

That’s not the purpose of it, as I understand it; it’s a token phrase generated to cajole it down a particular path.[1] An alignment mechanism.

The complement appears to be, “actually, that’s not right.”, a correction mechanism.

I'm not trying to be offensive here, feel the need to indicate that. But that prompt leads me to believe that you're going to get rather 'random' results due to leaving SO much room for interpretation. Also, in my experience, punctuation is important - particularly for pacing and grouping of logical 'parts' of a task and your prompt reads like a run on sentence. Making a lot of assumptions here - but I bet if I were…

> I bet if I were in your shoes and looking to write a prompt to start a task of a similar type that my prompt would have been 5 to 20x the length of yours

Why would you need such extensive prompting just to get the model to not re-implement authentication logic, for example? It already has access to all of the existing code, shouldn't it just take advantage of what's already there? A 20x longer prompt doesn't sound like a satisfying solution to whatever issue is happening here.

Claude needs a lot of context to keep it on rails IMHO. And, Claude Code is a closed source piece of crap agent framework.

Well, here's an even more insane claim: I'm infinity times more productive, as I just wouldn't even start projects without the LLM to sidestep my ADHD. Then, when the LLM invariably fucks up, I step in and finish things myself! Here are a few projects that I made these past few months that wouldn't have been possible without LLMs: * https://github.com/skorokithakis/dracula - A simple blood test viewer. * https://www.…

Well done, some of these projects look cool. Although I was just commenting on the irony of the parent comment.

What was the irony? I thought you were referring to the "3x speed" part as the insane statement.

I really hope benchmarking improves soon to monitor the model in the weeks following the announcement. It really seems like these companies introduce a new "buffed" model and then slowly nerf the intelligence through optimizations. If we saw task performance week 1 vs week 8 on benchmarks, this would at least give us more insight into the loop here. In an environment lacking true progress a company could surely "show…

I do wonder about this. I just don't know if it real or in our heads

It does feel like it has to be real. I've noticed it since chatGPT with GPT-3.5, once it hit big news publicly and demands were made on "censoring" its output to limit biases, etc. (not inherently a problem to do this with LLMs as a society, but it does affect the output for obvious reasons). Whatever workflow OpenAI and others have applied, seems to be post-release somehow? i'm ignorant and just speculating, but literally every model release i've noticed it. Starts strong, ends up feeling less capable days, weeks, months after. I'm sure some of it could be in the parallelization of processing that has to occur to service the large amount of requests. and more and more traffic are spreading it thin?
