pi-better-grok

Better Grok/xAI for pi — mirrors the pi-better-openai UX for SuperGrok subscribers: fast mode, subscription usage in the footer, footer polish, and a settings picker.

Install

pi install git:github.com/monotykamary/pi-better-grok

Commands

Command	What it does
/grok-fast	Toggle fast mode (reasoning_effort: "low" injected into xAI provider payloads while enabled and the model is allow-listed)
pi --grok-fast	Start with fast mode enabled
/grok-usage	Force-refresh and show SuperGrok subscription usage
/grok-usage debug	Show diagnostics (auth source, last fetch, config path)
/grok-resets	Inspect and redeem SuperGrok banked rate-limit resets
/grok-settings	Open the settings picker (footer, usage, fast mode)

Usage widget

Piggybacks pi's native xAI login (/login xai → Use a subscription; tokens in ~/.pi/agent/auth.json under xai). Falls back to xai-oauth / xai-auth auth-file entries and the official Grok CLI store at ~/.grok/auth.json.

Data comes from the same revision-pinned Grok subscription surface used by the community pi-grok-usage extensions:

1. GET https://cli-chat-proxy.grok.com/v1/user (identity)
2. GET https://cli-chat-proxy.grok.com/v1/billing?format=credits (with the x-userid header)

Status widget line: Usage: 66% left · ↺ 5d5h - Mon 5:34 PM · 1 banked reset (weekly period, reset clock, and available banked reset count). Defaults to the widget area below the editor, like pi-better-openai; set "footer": {"mode": "replace"} for the full custom footer.

Banked resets

SuperGrok plans earn banked rate-limit reset tokens: redeeming one restores the weekly usage limit early. /grok-resets lists the remaining inventory, asks which token to redeem when several are available, and always confirms before spending one — redemption is immediate and cannot be undone. The inventory is warmed at session start and refreshed on a 5-minute TTL, so the command opens instantly; the server re-validates every redemption, so a stale offer can never be consumed twice.

The inventory and redeem calls use the grok.com consumer billing gRPC-Web service (prod_mc_billing.ConsumerUiSvc/GetRemainingResets and RedeemReset) that the web usage page itself calls, authenticated with the same xAI OAuth token as the usage meter. This surface is undocumented; request shapes are pinned in src/resets.ts and schema drift is expected.

Cloudflare requirement (worked around): grok.com fronts this RPC with a managed challenge that non-browser clients cannot solve — even a perfect Chrome TLS impersonation (curl-impersonate) is challenged, because the site requires a cf_clearance cookie issued after a browser solves the challenge once. The cookie is bound to the browser's user-agent and IP. This is the same mechanism community Grok proxies (e.g. grok2api) rely on.

Because pi runs on the same machine (and IP) as your browser, supplying both values in config unlocks the surface. To get them: open grok.com in your browser, DevTools → Application → Cookies → copy cf_clearance; Network → any request → copy the User-Agent request header. When the clearance expires, /grok-resets says so explicitly and you re-copy the cookie. Without a clearance configured, the widget hides the count and /grok-resets explains the challenge instead of misreporting it as an auth failure.

pi-multiprovider

When pi-multiprovider pools several xai accounts, the session's active account (chosen with /switch-account) is resolved first for usage display and banked resets, and the usage widget refreshes on every switch. Without that extension, credential resolution is unchanged: pi's native xai OAuth, then xai-oauth/xai-auth auth-file entries, then the Grok CLI store.

Configuration

JSON config at ~/.pi/agent/extensions/pi-better-grok.json (global) or <project>/.pi/extensions/pi-better-grok.json (project):

{
  "persistState": true,
  "supportedModels": ["xai/grok-4.6", "xai/grok-4.5"],
  "fast": { "effort": "low" },
  "usage": {
    "enabled": true,
    "refreshIntervalMs": 60000,
    "showOnlyOnSubscriptionModels": true,
    "showResetTimes": true,
    "showBankedResets": true
  },
  "footer": { "mode": "status" },
  "resets": { "cookies": "", "userAgent": "" }
}

Unknown fields are preserved on write.

Roadmap

• /imagine via api.x.ai/v1/images/generations (API-key accounts)
• Live Search web tool (SuperGrok x_search)
• Footer pets (port from pi-better-openai)

Security

The cli-chat-proxy.grok.com surface is unofficial and reverse-engineered from the Grok CLI; treat schema drift as expected. This extension never logs or stores token contents and masks account IDs in diagnostics.
