PositiveGeneral text

“just quit bitching and go use GLM 5.3 Flash Super cheap, barely uses tokens, never has congestion issues.”

PositiveSpeed & latency

“GLM 5.3 flash running at 50/60tok/s decode with 2k tok/sec prefill and concurrency of 4 streams at 25-30tok/s decode each”

PositiveCoding

“I use GLM 5.3 Flash and DeepSeek v4 Flash 0731 via one of those places. My use case is programming and some custom workflows for various tools, and it's been great, both price and performance wise.”

PositiveLocal deploy

“GLM-5.3-Flash is pretty much as good as it gets, which you can comfortably run.”

PositiveGeneral text

“I use it as advisor for sol, works fine”

PositiveGeneral text

“GLM manages to consume less tokens and has a higher quality so it wins even though it's marginally expensive”

NegativeSpeed & latency

“GLM 5.3 Flash was slower and more expensive when I tried using it versus Deepseek Flash.”

PositiveCoding

“Feels great, also the normal one and I feel it very solid for programming tasks”

NegativeReasoning

“GLM-5.3-Flash is priced competitively but tends to hallucinate more for my use case scenarios.”

PositiveReasoning

“glm flash 5.3 beats opus 4.6 max thinking”

NegativeCoding

“GLM 5.3 Flash (NVFP4) on Hermes tried to delete my Hermes home profile accidentally instead of a sub-folder.”

PositiveSpeed & latency

“glm 5.3 flash, ds 4 flash 0723, qwen 3.8 flash next are all great and should fit. Not sure what the issue is. They are getting closer and closer to sota models, very fast.”

NegativeSpeed & latency

“Because GLM 5.3 Flash is a bit slow at times.”

NeutralSpeed & latency

“Speed feels about the same as GLM 5.3 Flash, so its not some turbo version.”

NegativeGeneral text

“GLM 5.3 flash is really bad for my use, i tested it with their free 100m tok”

NegativeCoding

“glm5.3flash during debugging will take actions that are equivalent to pulling out its own oxygen tube”

glm5.3flash在debug过程中会做出自己拔掉自己氧气管的操作

NegativeReasoning

“Glm 5.3 Flash is really aggressive with benchmark scores. In many cases, it's even less stable than V4 Flash, but the scores are terrifyingly high”

Glm 5.3 Flash 刷分刷得有点狠. 很多情况下,它甚至还没有 V4 Flash 稳定,但分数是高得吓人

MixedSpeed & latency

“Although it's slow, the activity duration is long enough, and the concurrency isn't particularly stingy. Currently it seems fine to handle several hundred million per night, and the entire activity lifecycle can support up to a billion, which is quite generous”

虽然慢但活动时间足够长,并发也不是特别抠 目前看一晚几个亿没问题,整个活动生命周期最多可以蹬百亿,相当大方了

NegativeGeneral text

“GLM 5.3 Flash is crushing benchmarks and is dirt cheap. This interested me so I moved our entire step to it and that was a disastor.”

MixedReasoning

“The model's coding ability is strong, but its knowledge update seems to have some issues. I asked it to use lark-cli to handle some problems, and it told me it didn't know about this thing and guessed I was probably referring to lark Python sdk. This is too ridiculous”

模型的coding能力很强,但是知识更新貌似有点问题,我让他用lark-cli处理一些问题,他和我说不知道这个东西推测我大概率说是说lark Python sdk。这个也太离谱了

NeutralCoding

“For paid coding plan users, from tonight until September 20th, the GLM5.3flash model can be called unlimited times in ZCode from 23:00 to 9:00 the next day each night”

对于付费的coding plan用户,今晚到9月20号,每晚23点到次日9点在ZCode里可以无限调用GLM5.3flash模型

NeutralGeneral text

“GLM 5.3 Flash is not fast, but low-cost. It's not suitable for direct human interaction because it thinks for a long time, even slower than glm5.3 locally. It's more suitable for being called by gateways like Xiaolongxia or Hermes to do specific tasks. And GLM 5.3 Flash is the cheapest, no need for tokenplan.”

GLM 5.3flash 不是快速,而是低成本 他不适合直接和人交互, 因为一次思考老半天,比 glm5.3 本地还慢 他比较适合 被小龙虾或者 hermes这种网关调用去干具体的活 而且GLM 5.3flash 是最便宜的,都不用 tokenplan

NegativeLocal deploy

“GLM 5.3 Flash runs on 256 GB with community weights. Official weights would require to raise the Sparks from 2 to 4 devices. At the current price point, a pill hard to swallow.”

PositiveImage / vision

“GLM 5.3 Flash for design. This combo is so cheap and pretty effective. Not Opus/Fable level but in reality close enough.”

NegativeCoding

“That's max and it didn't work great for my coding tasks in OpenCode.”

NegativeLocal deploy

“GLM 5.3 Flash which would need 8 to be comfortable there”

MixedGeneral text

“Been using glm 5.3 flash as subagents, i had to switch from max to high cause max overengineers too much”

PositiveSafety & refusals

“GLM 5.3 flash on the other hand has been willing to do pretty much anything I ask it, up to and including removing DRM, decompilation, and disassembly.”

NeutralReasoning

“model thinks its own reasoning is user input”

NegativeSafety & refusals

“Completely bypassing multiple safeguards to stop and ask questions. GLM 5.3-Flash in the last instance was also very wrong.”

NegativeSafety & refusals

“glm flash tried to nuke a bunch of files, im like woahhh hold on”
