@YRSM_Simon: Spent all day today using the local GLM 5.3 Flash to develop my product. 2k+ prefill, 50+ tokens per second, and the quality is quite good. I didn't notice a significant difference compared to Sol 5.6. For a Coding Agent, currently, no model makes me feel like it's absolutely necessary.

I’ve been using the local GLM 5.3 Flash all day to develop my product. With a 2k+ prefill and 50+ t/s, the quality is also quite good.
I don’t feel there’s a particularly noticeable gap compared to Sol 5.6. For building a Coding Agent, no single model currently makes me feel like I absolutely have to use it.
OpenAI (@OpenAI):
We’re ending our partnership with Cursor following its acquisition by SpaceX. Under our proposal, Cursor’s direct access to our models would end on November 12.
We know that the people most affected by this decision are the developers who rely on OpenAI models in Cursor. We care

This article criticizes the severe stability issues of the GLM-5.3-flash model in production, like silent failures for large requests and workflow disruptions, despite its good performance.
@Saccc_c: I used the newly released GLM 5.3 to create a landing page website for itself, and the overall animations and aesthetics are quite impressive. According to the official scores, GLM 5.3's coding capability has improved by 50% over the previous generation and tops the open-source models. After a few hours of experience, the front-end coding is basically on par with Kimi K3, and bug fixes are quick and precise.

Zhipu released the GLM 5.2 model, focusing on coding capabilities, open-source and supporting 1M context. Tests show it approaches Claude Opus 4.8 level in large engineering and coding tasks, but lacks multimodal capabilities and is limited by computational power, resulting in slower speed. The article also mentions Anthropic shutting down Fable 5 and Mythos 5 at the request of the U.S. Department of Commerce, highlighting the contrast between open-source and closed AI.

GLM 5.2 is an open-source AI model with a 1M token context window and strong benchmark performance, narrowly trailing Opus 4.8. The episode provides a practical setup guide for local or cloud use with tools like Cursor and Codex, and emphasizes chaining models for cost efficiency.
@xiaomovps: After a company starts using AI, they quickly hit several hard problems: whether data can be externalized, whether costs can be controlled, and whether to build internal models themselves.
