What to do about "model does not exist / no available channel"

90% of the time it's a group / model mismatch:

1. Go back to the Model Marketplace and select the group your token belongs to.
2. Confirm the model name you entered is actually listed under that group.
3. Copy the exact model name from the Marketplace and re-enter it in your client.

Also note: the claude-cconly group only supports Claude Code; third-party clients should use claude-max / claude-kiro.

Are there any hidden fees?

No. Tianshu is pay-as-you-go — you're only charged for actual usage, rates are public, and there's no monthly fee or minimum spend.

How do I top up? Is it credited quickly?

Top up with Alipay / WeChat Pay / cryptocurrency (e.g. USDT) in the Console → Wallet; it's credited at 1:1 instantly. If the payment window doesn't pop up, turn off your proxy / VPN and try again. See Add Credit for details.

How do I save money?

• For similar needs, prefer models / groups with lower rates; the differences are clear at a glance on the Model Marketplace.
• If you only use Claude Code, the claude-cconly group is usually the best value.
• Heavy Claude Code users can set up the Cache Optimization Proxy to save even more credit.

Do all models cost the same?

No. It depends on the model itself and the rate of its group; for live rates, see the Model Marketplace.

Long requests / image generation keep timing out?

Switch the endpoint to the direct route https://api.tian-shu.org, which is designed for long-running requests such as image generation and bypasses the gateway timeout. See Endpoints for details.

Can one token use all models?

No. Which models a token can use is determined by its group. We recommend creating separate tokens for Claude Code, Codex and image generation, each with the matching group.

What if my key is leaked?

Immediately go to Console → Token Management to delete / reset that token, then create a new one. Never expose your key in group chats, public repositories or screenshots.
