I like to compare models with a similar score on cost per task and output tokens per task since those measure two things I'm interested in: cost efficiency and token efficiency. Here's how GLM-5.3 compares to other models in a similar score and against GLM-5.2 to save a few clicks for others who care about these metrics:

    Model                        Score    Cost / Task    Output Tokens / Task
    -------------------------------------------------------------------------
    GLM-5.3 (max)                 59.5          $0.68                  41,107
    GLM-5.2 (max)                 53.0          $0.56                  32,200
    Claude Opus 5 (high)          61.5          $1.52                  21,353
    GPT-5.6 Sol (max)             60.9          $1.23                  16,879
    Grok 4.6 (high)               60.9          $0.84                  21,735
    Kimi K3 (max)                 59.7          $0.84                  25,474
    GPT-5.6 Sol (xhigh)           59.0          $0.87                  11,098
    Claude Opus 5 (medium)        58.6          $0.98                  12,459
    Qwen3.8 Max                   58.1          $1.13                  38,287
    Qwen3.8 2.4T A95B             57.7          $0.95                  32,472
    Claude Opus 4.8 (max)         57.3          $1.65                  33,557
    GPT-5.6 Sol (high)            57.3          $0.52                   7,545
    Muse Spark 1.2 (xhigh)        56.8          $0.40                  30,430
    GPT-5.6 Terra (max)           56.6          $0.51                  20,838
    GPT-5.5 (xhigh)               56.3          $0.69                  16,893
    Gemini 3.7 Flash (high)       56.0          $0.40                  36,847

Edited for accuracy and more models.

It would make reading and comparing a bit easier if the data was sorted by a dimension.

sourcecodeplz•about 1 hour ago

Muse Spark has a nice balance. not to mentions the Contribs version is old deepseek flash prices.

glub•26 minutes ago

Tested muse spark 1.2 because it was rated so high on design arena, and I've missed a model that can do nice UI in the hands of an operator with no UI skills.

It produced worse UI mockups than GPT and GPT models are already the bottom of the barrel here. The only model that performed well was Kimi K3 - insanely good, but expensive.

It's hard to trust benchmarks these days.

sscaryterry•about 1 hour ago

I found the sweetspot here: GPT-5.6 Sol (high) 57.3 $0.52 7,545

(Edit: TLDR; It gets on with it, makes the same mistakes you would, without overthinking and overengineering, most of the time)

teravor•about 1 hour ago

these $/task figures aren't very useful in my experience. it doesn't tell you how well it did the task.

generally I choose models by their intelligence and then personal preference from direct experience.

kolinko•about 1 hour ago

they make a ton of sense for tasks that are achievable with no prob by all models - e.g. writing scripts that do a specific thing etc.

teravor•about 1 hour ago

    > writing scripts

you can use a Gemini model completely for free doing that. no agent. aistudio.google.com

glub•about 1 hour ago

I've tested GLM 5.3 on the release day and Artificial Analysis is spot on. It's a really good model.

But my main takeaway was something else. I've used closed weight models for long enough that I've forgotten how good it feels to see reasoning tokens.

With GPT/Claude, you kind of hope that intent was captured well, that agent had all the information, all the tools it needed, because you won't see "hmmm it seems like nix flake isn't available here and I shouldn't install something globally" until it slopped out millions of tokens and wasted hundreds of dollars for 8 hours. With GLM and the likes, you just stop the disease right where it begins.

Havoc•about 1 hour ago

Yes, not necessary often but being able to stop something that is going off the rails is super useful. Especially if the root cause is prompt ambiguity - inject a clarification & it recovers

glub•31 minutes ago

It's also starting to go beyond reasoning and it's becoming much more problematic. Reasoning is one thing, but codex, for example now encrypts agent-to-agent messages as well, and compaction. I've no idea what subagents are instructed to do, or what they reported back in native codex.

The only thing that's keeping me is the value $200 subscription provides. If that value disappears, I see no reason why not to switch to something that isn't a black box.

BinRoo•about 2 hours ago

Beware of the benchmarks listed. SciCode and EnterpriseOps for instance: https://shukla.io/blog/2026-08/gym.html

Onavo•about 1 hour ago

The Chinese models also like to cut corners on stuff like science. Their scores on stuff like biotech and scientific knowledge is far from ChatGPT unfortunately. (Claude is pretty good but it just refuses all prompts).

markasoftware•about 2 hours ago

Very impressive score for the size, though token use is higher than k3 and far higher than proprietary models, and its price to performance isn't all that far ahead of k3 as a result

Havoc•about 2 hours ago

>token use is higher than k3 and far higher than proprietary models

GLM sets effort to max by default historically.

markasoftware•about 2 hours ago

Aa also benchmarked k3 at max

Zaheer•about 2 hours ago

Is it worth using these models if I have a claude code subscription already? The appeal of lower cost is nice but I haven't gotten over the switching cost yet.

robertn702•8 minutes ago

FYI, you can use your Claude subscription pricing with OpenCode via Meridian[0], which also makes it easier to try out other models when they come out. You can also use your other subscriptions in OpenCode with CLIProxyAPI[1]. The switching cost was relatively high, mostly from claude code plugins but completely worth it. I'm now mostly using GLM-5.3 and Codex models via OpenCode and barely using Claude which seemed unfathomable less than two months ago.

oceanplexian•about 1 hour ago

I use the $200 plan w/ Anthropic and run out of tokens half way through the week and supposedly they are progressively reducing the limits on all their subs even further.

At some point I will switch, $200 buys a lot of tokens on OpenRouter.

kilroy123•41 minutes ago

Same here. I'm switching to the Codex plan. It just doesn't go very far now. Especially if you use fable at all.

glub•about 1 hour ago

If anything, it's going to be more expensive. Price/performance ratio isn't there yet for frontier open weight models.

But regardless, you definitely should use a harness where switching models on the fly is easy. There's a reason why Anthropic uses their own proprietary formats/conventions anywhere they can - to lock you in when inference eventually commoditizes.

culi•about 2 hours ago

Use a unified proxy that lets you switch between models seamlessly. We are far from an equilibrium in this market and you will continue to have FOMO no matter who you pick if you go all in on one company

colingauvin•about 2 hours ago

At least by API usage, they aren't yet lower cost than subscriptions. Not sure about GLM's subscription plans though.

glub•42 minutes ago

GLM subscription is better than API, but significantly worse than Codex, even when used outside peak hours.

notatoad•about 2 hours ago

no, at subscription prices claude is a better value than GLM.

They're only a better value if you're paying API rates

colingauvin•about 2 hours ago

Tied for #1 by agentic index (with Opus 5).

colingauvin•about 2 hours ago

...do I take out a double mortgage to buy a 4 Spark cluster?

nvme0n1p1•about 2 hours ago

No, you use openrouter and spend 10% as much as using a proprietary model.

lisplist•about 2 hours ago

$20k is personal loan territory, not a second mortgage lol

colingauvin•about 2 hours ago

Not with my credit!
