Why “99% Cache Rates” Are a Red Flag for AI Inference Providers

Key Info

Some AI inference providers advertise “99% cache rates” as a sign of efficiency. An industry observer warns that DeepSeek is currently the only provider that can legitimately reach that level, so the claim often means the provider is wrapping DeepSeek — and may later switch to a different backend while keeping the same marketing number.

Highlights

• A 99% cache rate is an extreme number; at this point it is effectively a DeepSeek signature.
• Providers flashing that number may be reselling DeepSeek rather than running their own inference stack.
• The same providers can swap underlying models later and still repeat the claim, so buyers should treat the metric as a red flag and verify what they are actually paying for.
