<p>ok. maybe. I don't know. I'm asking how you know.<p>z.ai did go public on the HK exchange. They are under pressures similar to other public companies.<p>I know that China models are increasingly being trained and run using Huawei chips instead of Nvidia. I know China has a surplus of electricity from renewables (wind, solar, hydro).</p>

<p>What leads you to say China AI is giving up on open weights?<p>I've been using GLM for over 6 months and pretty happy.</p>

<p>z.ai models are open weights. GLM-5.1 is very close to Opus with obvious exception of session length.<p>Only academic models will be true open source as companies can't legally afford to disclose learning inputs.<p>In regards to "They want to train models on our engineering to replace us". Some software engineers in China can run circles around some of the best teams in Silicon Valley. Days of U.S. hegemony are over. I recommend you make peace and make friends.</p>

<p>I've been using z.ai and codex latest models since last September.
Each release has been an improvement.<p>codex handles longer sessions but the quality seems to decline and it tends to over engineer and lose focus. It will happily add slop on top of slop...which may pass immediate tests of "code works" but doesn't pass my criteria of "code as craft"<p>I'm using z.ai GLM with opencode. It's obvious when GLM loses its mind when the session gets too long.<p>I've been using AI to support programming for around 3 years now. The models have gotten amazing. However, unless there is a significant breakthrough I have determined that it's best for me to focus on short sessions.<p>I a) organize my work, b) improve my AGENTS.md, ensure source has appropriate comments to guide the models to the patterns and separation of concerns c) use shorter sessions d) review and test without AI. This approach means I still own my code. The AI is just an assistant.<p>With this approach GLM-5.1 is an excellent model. I never run out of token allotment on z.ai or codex plans. At this point, I only keep my OpenAI subscription as the ChatGPT desktop app is excellent at long web research tasks and I get codex with it.</p>

<p>Good breakdown.<p>I usually want the codex approach for code/product "shaping" iteratively with the ai.<p>Once things are shaped and common "scaling patterns" are well established, then for things like adding a front end (which is constantly changing, more views) then letting the autonomous approach run wild can *sometimes* be useful.<p>I have found that codex is better at remembering when I ask to not get carried away...whereas claude requires constant reminders.</p>

<p>Depends on your app cache needs. If it's moderate, I'd start with postgres...ie. not have operate another piece of infra and the extra code. If you are doing the shared-nothing app server approach (rails, django) where the app server remembers nothing after each request Redis can be a handy choice. I often go with having a fat long lived server process (jvm) where it also acts for my live caching needs. #tradeoffs</p>

<p>I've started using a container (podman) which is just for the AI tools. I start it up for Codex etc and let it access to the appropriate code directory outside the container.<p>Anyone else using this approach? Ideas on improvements?</p>

<p>> are they making progress?<p>* The Shanghai and Hong Kong stock market seems to have improved regulatory enforcement. I have no way of measuring this...just stories from others.<p>* Over the past 10 years the China gov pressed on with building more housing in part to dilute value. Each year they have warned that houses are for living, not speculation. Last year, they dumped a huge amount of cheap lending into the market to provide movement...warning this is the last step...a month ago the 2026 gov priorities list removed protecting the housing market...first time in modern history. Expectation is the next two years will see realized losses in property. It would be a huge mistake if the gov hasn't ensured regulatory enforcement of other segments have not reached maturity for the retail investor. We'll see...<p>* As for civil courts, over the past 20 years I've run into quite a few stories from friends and business colleagues that needed to go to China court. The stories are similar to what you may hear in the US. No one suggested the court/process itself was dodgy/unfair.</p>

<p>> What are they gonna do, sue in Chinese court?<p>If your hypothetical happens, yes.
China has been working hard to turn domestic investment away from housing. A trustworthy domestic stock market is key.</p>

<p>The high level description for Tokyo's management could apply to Shanghai. Replace Tokyo's "elected mayor/assembly" with "party member administrators". Each Shanghai district has its own management structure.<p>The vague description "run by the central government as a province rather than a city" is uninformative.<p>Lived in Shanghai 10 years. The city is well run for something of its magnitude. Mostly competent leadership and cultural alignment.</p>

<p>I spent a few years leading dev on decentralized exchanges, building bridges to other chains and building a sophisticated margin system on top of the trading pools.<p>A few things I think I've learned:<p>In its current state, most retail investors are simply supplying to the sophisticated investor.<p>Although some DeFi projects make a genuine effort to provide analysis tools to level the playing field, it's not nearly enough.<p>The safest least volatile yields in DeFi are lending your stable coins into a system such as aave. The yield is not far from a high yield USD savings account.<p>Exchanges such as Uniswap may be the most important legit tool in DeFi. The biggest problem is the liquidity provider's ability to protect their downside...so the investor adds on more sophisticated monitoring/hedging schemes. This gets us back to the retail investor being at a severe disadvantage.</p>
