Nex AGI Nex-N2.6 is now available in FastMetal chat
Nex-N2.6 is live in FastMetal chat. Nex AGI describes it as an agent model built on Z.ai's GLM 5.3 Flash, with about 321 billion parameters.
Nex AGI has not published benchmark results for it yet. The quickest way to see what the extra training changed is to read its answers next to GLM 5.3 Flash's on the model page (below).
What we checked before turning it on
- It reasons before every answer, and those reasoning tokens bill as output tokens.
- Image input works: it named the colors in a test image correctly.
- The context window is 262,144 tokens.
- It does not read PDFs. Paste the text of a PDF into the message instead.
Pricing
Nex-N2.6 bills per million input and output tokens, with a separate rate for cached input. Current rates are on the Nex-N2.6 model page, and billing is explained on /pricing. Usage is prepaid, so you can't be charged past your balance.
How to use it
- Create a FastMetal account.
- Add credit.
- Open chat, pick Nex-N2.6 from the model list, and ask. You can attach images to a message.
Nex-N2.6 is chat-only for now. To build an agent on the API, the base model is available as glm-5.3-flash.
Compare real answers first
