GLM-5.3-Flash Intelligence, Performance and Price Analysis

Impressive. It kicked everything between itself and Sol xhigh out of the Pareto frontier. Can't wait to try it out.

So how exactly is Anthropic and OpenAI ever going to pay back the trillions that they plan on spending?

Several factual errors about the model here. The input modalities are listed as text only, but the headline feature is image support. The context length should be 1048576 (so should GLM-5.3's, also wrong on the charts). https://docs.z.ai/guides/vlm/glm-5.3-flash#model-api

Can’t wait to try this out, and the only missing from this model for me is Image input support

Better than the latest Deepseek v4 Pro while being 3x cheaper in cost per task. Impressive!

Why does the top card say "Intelligence #1/173" when the bar chart further down shows it only at position 7? And the model isn't even shown in the speed bar chart just below. Such slop (the artificial intelligence website linked)

The analysis is still not compelling for me to switch from gtp5.6-luna to GLM-5.3-flash given - costs per task $0.05 vs $0.09 - speed 130 vs 88 - where GLM has only 5 more intelligence point: at this point few point is meaningless for most of models https://artificialanalysis.ai/models/comparisons/glm-5-3-fla... Been using Luna exclusively since the price drop, and i've been very satified with all tasks from planning, writing code, and other agent tasks. (just change thinking level from low <-> ultra) --- btw, I did try out Ox Alpha, the coding feels good but still not way better for me to switch to it.

Looking at these numbers IMHO, with Gemini you get the speed what you pay for. Intel Cost lig per ence Task Speed Gemini 3.7 flash 56 0.40 338 GLM 5.3 flash 57 0.09 49 Factor 1 4.4 6.9 I have both GLM & Gemini in a subscription and see no reason for choosing GLM 5.3 Flash. Working with de speed of Gemini 3.7 Flash is such a delight that I accept the hassle of working with Antigravity CLI, coming from Claude Code which I use for GLM.
