In my experience with the models (watching Claude play Pokemon), the models are similar in intelligence, but are very different in how they approach problems: Opus 4.5 hyperfocuses on completing its original plan, far more than any older or newer version of Claude. Opus 4.6 gets bored quickly and is constantly changing its approach if it doesn't get results fast. This makes it waste more time on"easy" tasks where the first approach would have worked, but faster by an order of magnitude on "hard" tasks that require trying different approaches. For this reason, it started off slower than 4.5, but ultimately got as far in 9 days as 4.5 got in 59 days.

I think that's because Opus 4.6 has more "initiative".

Opus 4.6 can be quite sassy at times, the other day I asked it if it were "buttering me up" and it candidly responded "Hey you asked me to help you write a report with that conclusion, not appraise it."

I got the Max subscription and have been using Opus 4.6 since, the model is way above pretty much everything else I've tried for dev work and while I'd love for Anthropic to let me (easily) work on making a hostable server-side solution for parallel tasks without having to go the API key route and not have to pay per token, I will say that the Claude Code desktop app (more convenient than the TUI one) gets me most of the way there too.

Try https://conductor.build

I started using it last week and it’s been great. Uses git worktrees, experimental feature (spotlight) allows you to quickly check changes from different agents.

I hope the Claude app will add similar features soon

Can you explain what you mean by your parallel tasks limitation?

[DaKevK]

Genuinely one of the more interesting model evals I've seen described. The sunk cost framing makes sense -- 4.5 doubles down, 4.6 cuts losses faster. 9 days vs 59 is a wild result. Makes me wonder how much of the regression complaints are from people hitting 4.6 on tasks where the first approach was obviously correct.

[MrCheeze]

Notably 45 out of the 50 days of improvement were in two specific dungeons (Silph Co and Cinnabar Mansion) where 4.5 was entirely inadequate and was looping the same mistaken ideas with only minor variation, until eventually it stumbled by chance into the solution. Until we saw how much better it did in those spots, we weren't completely sure that 4.6 was an improvement at all!

I haven't kept up with the Claude plays stuff, did it ever actually beat the game? I was under the impression that the harness was artificially hampering it considering how comparatively more easily various versions of ChatGPT and Gemini had beat the game and even moved on to beating Pokemon Crystal.

[MrCheeze]

The Claude Plays Pokemon stream with a minimal harness is a far more significant test of model intelligence compared to the Gemini Plays Pokemon stream (which automatically maintains a map of everything that has been seen on the current map) and the GPT Plays Pokemon stream (which does that AND has an extremely detailed prompt which more or less railroads the AI into not making this mistakes it wants to make). The latter two harnesses have become too easy for the latest generations of model, enough so that they're not really testing anything anymore.

Claude Plays Pokemon is currently stuck in Victory Road, doing the Sokoban puzzles which are both the last puzzles in the game and by far the most difficult for AIs to do. Opus 4.5 made it there but was completely hopeless, 4.6 made it there and is is showing some signs of maaaaaybe being eventually bruteforce through the puzzles, but personally I think it will get stuck or undo its progress, and that Claude 4.7 or 5 will be the one to actually beat the game.
