What this error usually means

Tngtech returning 400 / vision unsupported should not be judged from the message alone. Cross-check key shape, Base URL, balance, model permission, region/IP, and visible model list.

  • Provider: Tngtech
  • Error type: vision unsupported
  • Status code: 400

How to prove it during checking

Read-only check. Detection data burns after 5 minutes.

  • Run read-only identity first: confirm whether the key really belongs to Tngtech, not just a compatible protocol.
  • Then list models or run a lightweight probe: check whether models like DeepSeek R1T2 Chimera are visible and return stable evidence.
  • Finally record 400, error body, latency, egress IP, and reproducibility to separate balance, permission, route, or upstream issues.

Next action

vision unsupported should not only show failed. The console should return the next move: refill balance, change Base URL, switch model, add permission, change egress IP, hold listing, or monitor.
