Tokeness review: one API key for GPT/Claude/Gemini/Grok/DeepSeek/Kimi (with real caveats)

Tokeness is a third-party API gateway that lets developers access multiple model families, including GPT, Claude, Gemini, Grok, DeepSeek, GLM, and Kimi, with one key.

The review says it cuts billing and account-management friction with prepaid billing, transparent per-token pricing, a usable free tier, and invoicing support.

Major caveats remain: GPT and Claude are blocked for mainland China IPs, and all requests are relayed through Tokeness servers, raising privacy and compliance concerns.

Pricing is also variable and can shift with upstream costs, so the convenience comes with non-fixed rates and regional access limits.
