  • You need a price/context comparison before picking Kimi or DeepSeek.

This page is not for

  • Choosing a vendor without running the same task on both sides.
  • Ignoring review time, retry count, and integration cost.

Key points

  • DeepSeek-V4-Flash: 1M context, 384K max output, $0.0028 cache-hit input, $0.14 cache-miss input, $0.28 output per 1M tokens.
  • Kimi K2.x models have 262,144-token context and higher API prices, but add K2.7 Code, HighSpeed, Kimi Code CLI/IDE, and multimodal workflow entries.
  • The 50k input + 10k output sample is about $0.0098 on DeepSeek-V4-Flash cache miss and $0.0875 on `kimi-k2.7-code` cache miss.

What changed recently

  • `deepseek-chat` and `deepseek-reasoner` are deprecated on July 24, 2026 15:59 UTC.
  • Older Kimi K2 preview/thinking names and `kimi-latest` are not good defaults for new projects.

Explanation

For cost-sensitive API batches, start with DeepSeek-V4-Flash.

For coding workflow, test Kimi Code plus `kimi-k2.7-code`.

For long input/output, DeepSeek has the visible 1M and 384K max-output advantage.

FAQ

Which is cheaper for the 50k input + 10k output sample?

DeepSeek-V4-Flash is cheaper in this sample: about $0.0098 on cache miss.

When does Kimi still make sense?

When Kimi Code, `kimi-k2.7-code`, HighSpeed, multimodal input, or workflow time savings matter more than raw API price.
