🧠 GLM 5.2 · OPEN WEIGHTS · CODING MODEL
|
|
GLM 5.2 Just Beat GPT 5.5 on Coding. You Can Use It Free.
|
|
Zhipu AI dropped GLM 5.2, an open weights model that scores 62.1 on SWE-bench Pro against GPT 5.5 at 58.6. It also holds up strong on Terminal-Bench and FrontierSWE. It has a 1 million token context window and costs a fraction of what Claude Opus or GPT-5.5 charge. You can try it free right now through zenmux.ai with a Gmail signup. For production use creao.ai has it at much lower rates than the big closed models.
|
|
📌 SWE-bench Pro score of 62.1 puts it above GPT-5.5 at 58.6. Open weights so you can run it yourself or use cheap hosted APIs.
|
|
⚡ Free tier available on zenmux.ai with Gmail signup. No credit card needed to start testing it on your real coding tasks.
|
|
🔭 A 1 million token context window plus top coding scores at open source pricing is a big deal for any team burning budget on closed models.

Are you running your business on incomplete numbers?
Most small business owners have financials, but few have financial clarity. There's a real difference between books that are technically up to date and books that actually tell you what's going on in your business right now. When accounting is reactive — updated when there's time, reviewed at tax season — you lose visibility exactly when you need it most. You can't tell which clients are truly profitable. You can't spot a cash flow gap before it becomes a crisis. BELAY's outsourced accounting team changes that.
