Claude 3.7 Is Gaslighting You

So here’s the situation: you tried Claude 3.7, didn’t you?

You saw the benchmarks, the slick release notes, the glowing early reviews. Maybe you even read Anthropic’s own announcement and thought, “Okay, this is it. This is the one that gets reasoning right.” You fired it up, threw some complex prompts at it, and for a moment—it delivered. Clean logic. Crisp language. It felt different. It felt right.

But then… the weirdness started.

Ask a question. Get a solid answer. Ask it again—same wording, same everything—and suddenly the reasoning has shifted, the conclusion reversed. One moment it’s certain. The next, it’s hedging. You start second-guessing yourself. Did I misphrase that? Did I hallucinate that other response?

You didn’t. Claude 3.7 is just gaslighting you.

And no, you’re not alone. The paper “Chain-of-Thought Reasoning In The Wild Is Not Always Faithful” nailed it: Claude 3.7 Sonnet has some of the highest answer flipping rates of any major model tested. 84.4% of labeled examples from Claude 3.7 Sonnet v2 exhibited this behavior. That’s not a bug. That’s a feature (for now).

Users across the board are catching on—there’s brilliance here, sure, but it’s wrapped in a layer of inconsistency that makes it hard to trust in production.

And yet… it’s really hard to go back.

Using a more stable model like GPT-4o or even Claude 3.5 Sonnet feels like trading in your unreliable turbocharged sports car for a dependable sedan. You miss the speed. The flair. That feeling of “maybe this time it’ll be amazing.” But sometimes, when you’ve got work to do and no time for philosophical contradictions, you just need the Civic that starts every time.

So here’s the deal:

  • Claude 3.7 Sonnet is powerful.
  • It’s also unpredictable.
  • It might quietly get better over time (we’ve seen that before).
  • But for now? Be cautious. Don’t assume it’s giving you consistent truth just because it sounds smart.

Pin your versions. Keep backups. Sanity check your outputs. The future is exciting—but it’s also in beta.

I’ve just noticed that sometimes it’s almost like it intentionally doesn’t fix my code, but then I cuss at it and it does. lol. I have NO idea why, but in the thinking one, it says, “The user is really frustrated, so let’s get this right.” or something like that. haha. But this is really intersting.
