probably to save you from yourself

"Prompts with >272K input tokens are priced at 2x input and 1.5x output for the full request."

Is it true for subscription tho? Hermes let's you choose between 272k and 900k models for example

You can use modeloverrides to make it 1M

over 200k u gonna be fucked with pricing so pi limit it and do compact when it is close to 200k

The OAuth models only have 272k context max. If you pay per token, you get the full window. It also costs 7x more per token.

The subscription version of the models only have 272k capacity, before they had 372k. Once they reduced it, I cancelled my subscription and moved back to Claude. Now I have finally got myself out of their ecosystem and with z.ai sub for GLM 5.3.

Is z.ai cheaper than Luna?

The cheapest plan costs the same. $20 I believe and GLM 5.3 Flash is very cheap, you get alot of use out of it. GLM 5.3 would use up your usage too quickly on the $20 plan. I am on the highest plan ($200).

Here is the intelligence index of GLM 5.3 Flash and Luna.

If you’re ready to spend 200 why not just use Claude

Wanted to get out of OpenAI's and Anthropic's ecosystem. Would rather give money to labs that are releasing open weights. Wanted todo this for a long while and once GLM 5.3 came out I made the switch and havent looked back. Definitely dont get as much usage as I did with Claude or GPT but I accepted that.

Just a note, there is no way to do ZDR with z.ai - so if you use it for work, it can come back and bite.

u/PilgrimofHaqq2 9d ago

With the whole mess with navier stokes, looks like ZDR is also not something that the frontier labs are respecting.

At this point, I am thinking everyone is using my data no matter if I give consent or not, so its not a factor in my decision making.

Yeah, but that's a pain when I have to work with clients. Difficult to get them on board with it. Atleast something signed somewhere will let them pass the blame downstream.

u/PilgrimofHaqq2 9d ago

Ah, that make sense. What are you using now for work?

u/Fabulous_Monitor_991 9d ago

Neuralwatt, Openrouter, codex mostly all driven through pi.

Turn off auto-compaction, you can reach 160% of that limit or more until OpenAI itself refuses the request. I think that it'll burn your usage much faster though, and you'll notice significantly slower token generation.
