Z.ai models in Big-AGI

GLM for code and agents at Z.ai's own rates - on a curated catalog that survives Z.ai's broken listing and hides models Z.ai advertises but doesn't serve.

Get started in 3 steps

1

Create an API key at the Z.ai console.

2

Paste it into Big-AGI's model settings.

3

Start chatting, or Beam it against other models and fuse the answers.

Running Z.ai in Big-AGI

Add your Z.ai API key and run the GLM models at Z.ai's own API rates. Big-AGI adds no markup and no intermediary: billing runs directly between you and Z.ai, and your keys stay in your browser.

  • Your key, your billing. Usage is billed by Z.ai to your account. Big-AGI does not meter or charge for model usage.
  • Strong at code and agents. GLM is tuned for coding and tool use, a capable and cost-effective pick for daily work.
  • A catalog that doesn't break. Z.ai's own model-list endpoint is unreliable, so Big-AGI runs from a hand-curated list of GLM models and layers a live check on top just to catch brand-new releases. A broken listing never takes the catalog down, and a model Z.ai advertises but doesn't actually serve gets hidden so you never pick something that would just fail.

Why run GLM here?

Z.ai's own chat product is a reasonable way to try GLM, but it only ever shows you GLM's take on a prompt. Beam sends the same prompt to GLM and to GPT, Claude, or Gemini at once, so a code review or a debugging session gets more than one model's opinion before you act on it. You also get parameters a consumer chat interface does not surface (temperature, system prompt, per-turn model swaps), and a key that stays in your browser instead of sitting on Z.ai's servers.

Your keys and your data

Turn on Direct Connection and the browser calls Z.ai directly, bypassing the Big-AGI server, whenever your key is client-side and Z.ai allows it. Your keys stay in your browser. Chats are stored locally first and sync only if you turn it on. The AI Inspector opens on any message to show the exact request sent to Z.ai, the token counts, and a cost estimate for that call.

GLM in Beam

Run GLM in parallel with Claude, GPT, and Gemini on the same prompt, then reach for Fusions: several strategies that combine, cross-check, and synthesize the parallel answers, which beats just picking the single best one. Parallel runs use more tokens than a single chat.

Bring your Z.ai key. Keep control.

Your key, your data, your choice of model. Big-AGI's Open branch is open source and self-hostable, so you can check exactly how Z.ai is called.
