I got their z.ai plan to test alongside my Claude subscription; it feels about on par with something between sonnet 4.0 and sonnet 4.5. It's definitely a few steps below current day Claude, but it's very capable.
When you say "current day Claude" you need to distinguish between the models. Because Opus 4.5 is significantly ahead of Sonnet 4.5.

z.ai (Zhipu AI) is a chinese run entity, so presumably China's National Intelligence Law put in place in 2018, which requires data exfiltration back to the government, would apply to the use of this. I wouldn't feel comfortable using any service that has that fundamental requirement.

#53Better link: https://iquestlab.github.io/ But yes, sadly it looks like the agent cheated during the eval
According to https://github.com/IQuestLab/IQuest-Coder-V1/issues/14#issue... the result is still good after fixing the cheating problem. 76.2% (from 81.4%) which still beats Opus 4.5 (74.4%)!!

None of these open source models actually can compete with Sonnet when it comes to real life usage. They're all benchmaxxed so in reality they're not "nipping at the heels". Which is a shame.
M2.1 comes close. I'm using it now instead of Sonnet for real work every day, since the price drop is much bigger than the quality drop. And the quality isn't that far off anyway. They're likely one update away from being genuinely better. Also if you're not in a rush, just letting it run in OpenCode a few extra minutes to solve any remaining issues will cost you only a couple cents, but it will likely get the same e…
