-Gemini 2.5 Pro is Google's flagship model. It has a **free tier** with generous daily limits, making it the easiest drop-in Claude replacement for most OpenClaw users.
+Gemini 2.5 Pro is a strong Claude replacement for many OpenClaw setups, especially if you want a direct API-backed provider instead of relying on Claude subscriptions.

+Use the current OpenClaw auth flow:
 
 ```bash
-openclaw auth add --provider gemini --key YOUR_GEMINI_API_KEY
+openclaw models auth login --provider gemini
 ```
 
-Or add it directly to `~/.openclaw/openclaw.json`:

 ## Step 4: Restart the gateway
 
 ```bash
-# Graceful restart (preferred)
-kill -SIGUSR1 $(pgrep -x openclaw-gateway)
-
-# Or full restart via systemd
-systemctl --user restart openclaw-gateway
+openclaw gateway restart
 ```

 ## Verify it's working
 
-Send a message to your OpenClaw agent. Check gateway logs:
+Quick check:
 
 ```bash
-journalctl --user -u openclaw-gateway -f | grep -E "gemini|model|error"
+openclaw models status --plain
 ```
 
-You should see `gemini` in the provider output, not `anthropic`.
+Optional live auth probe:
+
+```bash
+openclaw models status --probe --probe-provider gemini
+```
+
+You can also watch gateway logs while sending a test message:
+
+```bash
+journalctl --user -u openclaw-gateway -f | grep -E "gemini|model|error"
+```

 ## Troubleshooting
 
 **`PERMISSION_DENIED` or `API key not valid`**
-→ Double-check the key in `openclaw.json`. No extra spaces or quotes.
+→ Re-run:
 
-**`RESOURCE_EXHAUSTED`**
-→ You've hit the free tier limit. Wait until midnight Pacific, or upgrade to a paid Gemini API key (~$7/MTok for 2.5 Pro).
+```bash
+openclaw models auth login --provider gemini
+```
 
-**Model not found**
-→ Check OpenClaw version supports Gemini. Run `openclaw --version`. Update if below v2026.3.x.
+Then paste the key again carefully.
 
----
+**`RESOURCE_EXHAUSTED`**
+→ You likely hit Gemini rate limits or quota. Check your current Google AI Studio limits/pricing and wait for quota reset if you’re on a free tier.
 
-## Cost estimate (paid tier)
+**Model not found**
+→ Check your OpenClaw version:
 
-| Usage | Cost/month |
-|-------|-----------|
-| Light (10k msgs) | ~$2 |
-| Medium (50k msgs) | ~$8 |
-| Heavy (200k msgs) | ~$30 |
+```bash
+openclaw --version
+```
