Zed
A fast editor. Settings are a JSON file.
Three fields. Copy, don’t type
url
https://cheapai.lol/v1
model
claude-opus-4.8
Do it in order. Don’t skip
Open Zed and press Cmd+Shift+P (Mac) or Ctrl+Shift+P (Windows/Linux) for the command list.
Type: Zed: Open Settings. The settings.json file opens.
Find or create a language_models section, and openai inside it.
Set two fields: api_url to https://cheapai.lol/v1, and available_models to a list containing claude-opus-4.8.
Save. Zed asks for the key in its own dialog — paste it in full, including sk-.
Open the Assistant panel and type “hi”.
Check
Open chat in this app and type: hi. A reply means it’s wired correctly.
If it didn’t start
- “401 / unauthorized / invalid api key” — the key was not copied whole. It starts with sk- and has no space at either end.
- “model not found” / “named models unavailable” / model in red — the name must match exactly: claude-opus-4.8. Not “Opus 5”, not opus, not claude-3, not gpt-4.
- The app shows no models — reopen its settings page: the model list is served from our address and appears once the Base URL and key are right.
- “Connection error” / spinner and silence — wrong Base URL. Almost every app wants the address with a /v1 tail.
- “/v1/v1” in the error — the app appends /v1 itself. Drop the tail, leave the site address.
- It replied, then stopped — you ran out of tokens. The balance is in your dashboard. Topping up on FunPay from the same nick lands on the same key.
