An open-source AI language model from Z.ai (Zhipu AI), described as the best open-source model in the world at time of release, noted for strong front-end design capabilities at lower cost than frontier models.

What else do they all swear by?

What creators think

Riley Brown, Claire Vo, and Guillermo Rauch each endorse GLM 5.2 with detailed reasoning, with cost and speed as the most consistent themes — Claire Vo paid $3.36 for roughly 6 million tokens, and Guillermo Rauch calls the fast variant "astonishingly fast" after adding it to Vercel AI gateway. Riley Brown says it passes his vibe check and performs close to Claude Opus 4.8 and GPT 5.5 at a fraction of the price, while Naval Ravikant recommends it specifically because it answers questions that frontier models refuse, with fewer guardrails on sensitive topics. Several others mention it as a benchmark reference or a compelling self-hosting option without offering a direct recommendation.

How GLM compares

Claude Direct rival
Anthropic's AI assistant

GLM is open-source and much cheaper. Riley says it nearly matches Claude Opus at a fraction of the cost, and Naval picks GLM when Claude refuses to answer.

Guillermo Rauch

"GLM dropped — we added it to Vercel AI gateway. It's an incredibly good model, GLM 5.2. Within days, we had a fast variant that was four times faster. GLM 5.2 fast is astonishingly fast and it's only getting faster. If I have an agent th..."

Compared favorably to Claude Opus for cybersecurity tasks; recommended alongside Grok for price-performance; Kimi raises the bar further

JC
Jason Calacanis

"I went to OpenRouter, I got my own keys, I've been playing with GLM. I found that GLM 5.2 performs extremely well and our tasks are literally getting cut in half using the same model but with a different harness."

Used as alternative to Claude and OpenAI frontier models; dynamic routing falls back to Claude when needed

Naval Ravikant

"You can always just switch to GLM 5.2 and it'll just do it. Have the time of your life. Go ask it any question about race, gender, immigration, mental health, doctor advice, legal advice."

Recommended as alternative to frontier models (Claude, ChatGPT) when they refuse to answer; also compared to Grok which Naval says is 'a little neutered'

Riley Brown

"This model after spending a ton of time actually using it, I do believe that it passes the vibe check. I think that it's getting close to the frontier labs, specifically Opus 4.8 and GPT 5.5. I also connected GLM 5.2 to my Notion, to my ..."

Compared to Claude Opus 4.8 and GPT 5.5 (frontier models it rivals at a fraction of the cost); positioned as the best open-source model available

Riley Brown

"GLM 5.2 is the best open-source model in the entire world. And I guarantee you, you are going to be surprised at how powerful it is. Over the last 48 hours, I've just been testing GLM a ton. I highly recommend you start looking into that."

Slightly worse than Claude Opus 4.8 but significantly cheaper; positioned as the best open-source alternative to expensive frontier models like Claude Fable/Opus

Anish says GLM does exactly what you ask and nothing more, while Kimi is more open and creative. Scott notes GLM made a big wave but less public buzz than Kimi.

"You can get to the Pareto frontier with these, you know, Kimi K3 or pick your favorite, like GLM, open source model."

Kimi K3

Anish Acharya

"GLM5.2 and GLM5.3 are great examples of this — they're very literal and they'll only do exactly what you told them to do and nothing more."

Contrasted with Kimi K3 which is more open, presumptuous, and creative

The Prof G Pod – Scott Galloway

"Other Chinese models like GLM — GLM caused a very big wave. It may not have done the rounds in the same way that Kimi did, but it was certainly a great model."

Compared to Kimi K3 as another Chinese open-source model making an impact

Anthropic Direct rival

GLM costs far less and still matches results, say Aileen's portfolio companies. Anthropic and OpenAI models refused to help when GLM stepped in.

"Hugging Face had to fall back on a self-hosted Chinese open-weight model, specifically GLM 5.2, just to investigate their own breach."

"A lot of our portfolios have been playing with it and they're saying that they're getting equivalent results for a fraction of the cost. And I think that's why they are all getting ready, if they're not already, to be model agnostic."

ChatGPT Direct rival

GLM 5.2 is said to rival ChatGPT 5.5; GLM is easier to fine-tune than closed-source models like ChatGPT.

Dave Blundin

"Within open weights, you might want to start with the new GLM model which has fewer parameters but it's still a very long context window which gives you more flexibility. It's less locked into its training than the closed source models. ..."

Preferred over closed-source models for fine-tuning; mentioned alongside GPT-2/GPT-3 as historical fine-tuning reference

The Prof G Pod – Scott Galloway

"Z.ai just launched ZCode, a coding agent for its GLM 5.2 model said to rival ChatGPT 5.5 and Claude. This GLM 5.2 has climbed to the top of the western usage charts on third-party development platforms such as OpenRouter."

Said to rival ChatGPT 5.5 and Claude; reportedly bested Claude Fable on design arena leaderboard
