Any chance you'll retest with latest iterations of models? Opus 4.8, GLM-5.2, Kimi K2.7, etc

Even for a ui change fable complained about policy issues. This model is unusable

I had a pretty rough experience with Fable today. At first, Claude showed a message that Fable was available again, but if I typed /model it showed the same "disabled" state for the export controls, so that was sloppy. After I got it working (I had to login again), I asked it to do a security audit of a server I've written, and it spent a few tokens and then "flagged" the request and downgraded to Opus 4.8. Opus 4.8 just kind of glazed me for writing secure code without finding anything important. By the way, I ran ccusage afterwards and if I had been paying API rates I would have apparently spent $6.88 for that. Amazing stuff Anthropic.

Wait what? gpt5.5 is better than fable. I thought fable was the endtimes?! Wonder if this is because fable swirches down to opus for somethings without telling you?

Takeaways Which model to use for generating architecture. The simpler the decision you need to make, the more readily you can just take a proposal from Fable or GPT-5.5. And now that Fable is unavailable outside the US, the choice between Opus and GPT is far from obvious. As a quick default I'd lean toward GPT.

I'm curious how folks here are using LangGraph
