핵심 요약
최근 출시된 오픈소스 AI 모델인 GLM 5.2는 클로드 오푸스(Opus)급 성능을 보여주면서도 비용은 거의 공짜 수준으로 저렴하다. 클로드 코드(Claude Code) 등에서 구동 가능하며, 가끔 오류가 나긴 해도 가성비가 워낙 압도적이라 일상 코딩 작업에서 최우선으로 쓰게 된다. 오픈소스라 갑작스러운 서비스 중단 리스크가 없고 100만 토큰의 대용량 메모리까지 지원해서 프로젝트 전체를 기억하는 게 큰 장점이다.
주요 포인트
- 클로드 오푸스 대비 5분의 1 이하 가격인데도 일반적인 코딩 작업에서는 오푸스와 성능 차이를 느끼기 힘들다.
- 앤트로픽의 Fable 5가 규제로 하루아침에 꺼진 사례처럼 폐쇄형 모델은 중단 리스크가 크지만, 오픈소스인 GLM 5.2는 그럴 걱정이 없다.
- 총 7,000억 개(700B) 매개변수 중 작업당 400억 개(40B)만 활성화하는 스마트한 구조 덕분에 구동 비용이 매우 싸다.
- 100만 토큰의 컨텍스트 창을 지원하므로 프로젝트 코드를 끝까지 잊지 않고 머릿속에 담아둔 채 작업한다.
- 단순 토이 프로젝트가 아니라 실무에서 쓸 수 있는 브랜드 협찬 CRM 개발 같은 실제 작업에 직접 투입해 성능을 검증했다.
Okay, I'm just going to say the AI that I reach for first right now is not Opus. It's a free open source model that just came out some days ago. It's called GLM 5.2. And for most of what I throw at it all day, it is so close to the model that cost me five times more that I genuinely cannot tell them apart. And most importantly, it can run in cloud code and codecs. And right now, there's a ton of noise about it. Everyone is calling it the open-source Opus Killer. And I'm not going to add to that. I just used it for a few days on real work, the actual stuff that I do. So, here's my honest answer right up front before any of it. On most of the stuff that I built and threw at it, you genuinely could not tell me which one the cheap open- source one actually built and which one came from the one that actually cost me five times more. They are that close. I will say that Opus only really pulls ahead on the hardest, the longest jobs. And yeah, GLM did break on me a couple of times along the way. But for most of my day at a tiny fraction of the price, it's now the thing that I reach for first. So, the one question for this whole video is very simple. Can the cheap open- source one actually keep up with the expensive one? Let me show you exactly what I found. So, really quick, let me just preface what this thing even is because there's two things about it that truly matters here. First, obviously, it's open source. The model itself, it's out in the open. Anyone can download it and build on top of it. So, a model this good, it's just put out there for literally anybody to have. That almost never happens. And this matters more than this actually sounds because just the other week, one of Enthropic's most powerful models, Fable 5, got switched off overnight from the government. it's completely gone. Nobody who was building on it had a say. And that's the risk with a closed model that you do not own. An open-source one, on the other hand, like GLM 5.2, once it is out, nobody can take this back. Number two, it's built to be cheap. So, this is a huge model. There's over 700 billion parameters under the hood, but it's smart about it. So, for any one task, it only switches on a small piece of itself, about 40 billion. And that's the main reason it's so cheap to actually run. And beyond that, it can hold about a million tokens at once. So, it keeps your entire project in its head instead of just forgetting the start by the time that it reaches the end. So, that's the pitch with this. It's open. It's cheap to run. It's genuinely capable, and it has a big memory. But, I didn't really care about any of that until I gave it something real to build. So, that's what I did. Let me show you that. I didn't want to just build a to-do app or just some toy that's idealistic and not really helpful. I wanted something that I would actually use. So, I gave it a real job, and that was just to build me a sponsorship CRM. So there's a place to actually track our brand deals, who I'm talking to, what they're paying, what I owe them, the whole pipeline. So the kind of thing that you would normally pay for or build yourself over a weekend, and that is what GLM gave me back. So look at this. Like this is a real application. It's got a pipeline board. It's got deals moving across stages. We have the lead negotiating one live. And each card's got the brand, has the money, the due date, whether they've paid or not. And there's a dashboard with the totals 69,000 in pipeline all added up correctly. And with this, it actually works. So I can grab a deal. I can even drag it across to a new stage and watch like it just remembers with this. So I can refresh the page. It's all still there. Saved it. And none of this is just a mockup. Like this is a working tool inside of our team. And it seated it with eight real looking deals. So it actually feels alive the second that you open it. With that said, here's my honest measure for the whole video. Opus. I give Opus the exact same job. In Opus' version, it did come out a little nicer. So, it's darker. The spacing is a touch cleaner. Feels slightly more like a designer touched it, which isn't the most important thing. That's just aesthetics. If you put them side by side, Opus wins on looks, just by a hair, I would say. But GLM, it was definitely more complete and it did everything that I asked for. It works. And the part that truly matters is the whole application start to finish, it was about 300,000 tokens of work. And on GLM, that came out to around 40 cents. So, the same build on Opus that was about $3. So, for a result this close, that's the moment that it stopped being just a toy and something that's idealistic for me. By the way, if you guys want to build the exact same thing, I dropped a free guide inside of our community with the full setup and every prompt that I use today so you can follow along start to finish.
