  for long horizon tasks they drop grpo-variant and go back to critic based ppo with token level adv. interesting!! [image]

• @code_star Cody Blakeney on x

  This is kind of insane. Seems like we have recursive self-improvement in the open source now. Impressive for _only_ 753B parameters. Congrats to the @Zai_org team! [image]

  And then you'll look back and see how I told you Chinese labs will catch up and leave the US labs in the dust. - Proverb, Bilal tweets circa 2026

  🚨 GLM-5.2 is @Z dot AI's latest model with open weights (MIT license). Let's go! Key details: 🧠 Significant improvements in coding, agentic tasks, and reasoning 📏 1M token context window ⚖️ Two modes: (max) for highest performance and (high) for better token efficiency 🔓 [image]

• @tomgreenwald Tom Greenwald on x

  81% on Terminal Bench 2.1 😱

• @thezachmueller Zach Mueller on x

  The MIT though 😍 Looks like a fantastic model to say the least. Will have a model card up post RMNP next week but https://z.ai/ remains one of my favorite labs

  Lord Voldemort, the name that shall not be spoken Z AI/GLM-5.2 team so afraid of Kimi 2.7 that they didn't even include Kimi in the benchmarks 😀

• @ksimback Kevin Simback on x

  Playing with GLM-5.2 Just ran a long code review with it and it found a handful of items that GPT-5.5 missed, and GPT agreed with them So far I'm very impressed Going to use these two in combo going forward

  GLM-5.2 is out and it's fully open! - 1M context window - MIT licensed - stronger long - horizon coding agents - two reasoning modes: max and high - same API pricing as GLM-5.1 https://z.ai/ built this one around long-running agent work. large codebases,

• @ollama @ollama on x

  🤯 GLM-5.2 is here — built for long-horizon coding and agentic tasks, now with a solid 1M-token context. The strongest open-source coding model yet! Available now on Ollama's cloud, hosted in the US on the latest @NVIDIAAI Blackwell datacenter GPUs. Privacy policy and zero [image]

• @calvinchen Calvin Chen on x

  GLM 5.2 is an impressive model and performed better than GPT 5.5 on FrontierSWE! Excited to see more labs using FrontierSWE to measure long-horizon capabilities for coding We're working on some improvements to FrontierSWE and launching a v2 soon :) [image]

• @andrewcurran_ Andrew Curran on x

  Extremely powerful and MIT open-source. Mutuals who had early access are giving it great reviews. [image]

• @xeophon Florian Brand on x

  used it the past few days and it is a great model. still using a bit too many tokens for now (which in combination with CN servers makes it slow), but it knows how to use sub agents to explore things and then does so :) it being MIT is very much welcome, congrats zhipu!!

• @bindureddy Bindu Reddy on x

  GLM 5.2 Is Open Weights And Rocks In Coding and Agentic Loops Another day, another kick ass open-source model!! Kimi 2.7 and GLM 5.2 are in an intense competition Available in ChatLLM alongside Opus 4.8 and GPT 5.5 TODAY [image]

  Lets go, GLM-5.2 released as Open Weights model. tl;dr -1M context window -MIT-licensed open weights -Stronger long-horizon coding agents -Two reasoning modes: max and high -Same API pricing as GLM-5.1 Zai says GLM-5.2 was trained specifically for large-scale implementation, [ima…

• @resorcinolworks @resorcinolworks on x

  They have reached Opus 4.8 levels already. Give them 2-3 months more, and they will easily reach Fable levels of SWE workbench evals. Chinese models will pave the path for humanity's future.

• @mhdfaran Farhan on x

  Open-weight models are getting scary good. GLM-5.2 brings frontier-level coding, long-horizon reasoning, 1M context, and MIT license. This is the kind of release builders should pay attention to. [image]

• @andrew_n_carr Andrew Carr on x

  deepswe, terminal bench 2.1, and swe atlas correlate the most strongly with “good coding vibes” based on all the open models I've tested. that puts GLM-5.2 comfortably in the lead for open weight models. 700B params is all you need?

• @msanterre Max on x

  Well this is not good for American labs IPOs.

• @chrissgpt Chris on x

  Holy shit they opened sourced a model that bears Gemini 3.1 pro on everything 🤯 [image]

• @sentdex Harrison Kinsley on x

  Zai was gracious enough to give me a key to test out GLM 5.2. I used it on a few simple tasks and quickly realized this model is on another level. I committed to using GLM 5.2 solely for the weekend and yesterday on everything from simple data analysis, random queries, side

• @tugot17 Piotr Mazurek on x

  very cool to see this used in the actual model; indexer is the main bottleneck for inference speed in DSA and it seems competently unnecessary to have it per layer [image]

• @ai_for_success AshutoshShrivastava on x

  Open source must win. What's happening with Fable 5 and Anthropic makes this even more important now. Z ai just dropped GLM 5.2, an insanely powerful open source model beating Gemini 3.1 Pro and getting very close to GPT 5.5 and Opus 4.8. - Huge improvements in coding and [image]

• @zephyr_z9 @zephyr_z9 on x

  Zhipu has the best post-training stack in China

• @teortaxestex @teortaxestex on x

  GLM 5.2 is apparently the strongest Chinese model, and it'll be open this is quite a jump on CritPt. They have *finally* started to build general reasoners. I think it'll be very competitive on ARC-AGI 2 and WeirdML, too [image]

• @scaling01 @scaling01 on x

  We will see more of this later this year Chinese labs are now really starting to hill-climb the way we have seen monthly improvements from OpenAI and Anthropic I still want to see super long-horizon tasks for open models, but there's already a bunch of good coding benchmarks

• @designarena @designarena on x

  BREAKING: GLM-5.2 is now 1st on Design Arena. With an Elo of 1360, GLM-5.2 has jumped ahead of the now unavailable Claude Fable 5. And it's open weights. This is an improvement of 4 positions and 27 Elo points to achieve one of the highest Elo scores in our code categories [image…

• @teortaxestex @teortaxestex on x

  > We propose IndexShare, which reuses the same indexer across every four sparse attention layers, reducing per-token FLOPs by 2.9× at a 1M context length. We also improve GLM-5.2's MTP Good demonstration that a lot could be squeezed out of “mere” DSA on benchmarks, too. [image]

• @proximalhq @proximalhq on x

  GLM 5.2 ranks #3 on FrontierSWE. It is only behind Fable 5 and Opus 4.8, and it outperforms GPT-5.5. This is the first model that closes the large gap between models from Anthropic / OpenAI and other providers, and it is the strongest open-weight model by far. [video]

  Still hard to expect the unexpected with AI. It goes to show how skilled many of the scientists are in China. They're hitting high peaks with much less compute. Overall, I think the US models are really ahead, but you can't just discount the Chinese labs. Not at all.

• @emollick Ethan Mollick on x

  Compare GPT-5.2 from 7 months ago with the new GLM-5.2 Deep Think Max's: “create a visually interesting shader that can run in twigl with an infinite city of neo-gothic towers partially drowned in a stormy ocean with large waves” “Make it better” GLM-5.2 also had a couple errors …

• @vittostack Vitto Rivabella on x

  WTF is going on right now?!? Second on front end arena, FIRST on design arena. By far the best week for open source models ever.

• @teortaxestex @teortaxestex on x

  I don't trust arenas much. Waiting for AA scores I get the feeling this is the real one. Actual, solid, all-around excellent model, genuine frontier class
