DeepSeek V4-Pro vs Kimi K2.7 Code

DeepSeek · China  |  Moonshot AI · China · Updated June 2026

Quick verdict

Pick DeepSeek V4-Pro for open-weight 1.6t moe (~49b active) — deepseek's largest, self-hostable or 1m-token context with up to 384k output tokens. Pick Kimi K2.7 Code for long-horizon agentic software engineering or token-efficient reasoning (~30% fewer than k2.6). On a tight budget at scale, DeepSeek V4-Pro is the value pick.

DeepSeek V4-Pro (DeepSeek) and Kimi K2.7 Code (Moonshot AI) are two of the models people most often weigh against each other in 2026. DeepSeek V4-Pro is deepSeek's 1.6-trillion-parameter open-weight model at $0.435/$0.87 — strong open-weight coding and a 1M context at a fraction of flagship prices. Kimi K2.7 Code is moonshot AI's open-weight 1T-parameter MoE model (32B active) tuned for long-horizon agentic coding, always reasoning yet ~30% more token-efficient than K2.6. They diverge most on price and context window — each quantified below from the models' real specs.

Moonshot AI's open-weight 1T-parameter MoE model (32B active) tuned for long-horizon agentic coding, always reasoning yet ~30% more token-efficient than K2.6 — and it is the newer of the two.

Token-efficient reasoning (~30% fewer than K2.6)

Kimi K2.7 Code

Kimi K2.7 Code lists token-efficient reasoning (~30% fewer than K2.6) among its strengths; DeepSeek V4-Pro does not.

Open-weight 1T MoE, self-hostable

Kimi K2.7 Code

Kimi K2.7 Code lists open-weight 1T MoE, self-hostable among its strengths; DeepSeek V4-Pro does not.

Lowest cost at scale

DeepSeek V4-Pro

At $0.435/$0.87 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Largest single-prompt input

DeepSeek V4-Pro

Its 1M window is about 3.8× larger than Kimi K2.7 Code's 256K, fitting roughly 1,500 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

DeepSeek V4-Pro

At $0.435/$0.87 per 1M tokens it undercuts Kimi K2.7 Code, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

DeepSeek V4-Pro

Larger 1M window fits more in one prompt.

Anyone whose priority is open-weight 1.6t moe (~49b active) — deepseek's largest, self-hostable

DeepSeek V4-Pro

It is specifically built for that.

Anyone whose priority is long-horizon agentic software engineering

Kimi K2.7 Code

That is its strongest area.

DeepSeek V4-Pro: where it fits

DeepSeek's 1.6-trillion-parameter open-weight model at $0.435/$0.87 — strong open-weight coding and a 1M context at a fraction of flagship prices. Released April 24, 2026 by DeepSeek, it is built for open-weight 1.6T MoE (~49B active) — DeepSeek's largest, self-hostable, 1M-token context with up to 384K output tokens, permanent low pricing at $0.435/$0.87 per million, set May 2026, and sources place it near the top of open-weight coding, around 80 on SWE-Bench Verified.

Its trade-offs are real: independent SWE-Bench Verified placement is inconsistent across sources, pro and Pro-Max variants are quoted with different scores, text and code only — no image, audio or video, and overlaps DeepSeek V4 and V3.2 already in this comparison. At $0.435 in / $0.87 out per million tokens, it sits in the budget price band.

Kimi K2.7 Code: where it fits

Moonshot AI's open-weight 1T-parameter MoE model (32B active) tuned for long-horizon agentic coding, always reasoning yet ~30% more token-efficient than K2.6. Released June 12, 2026 by Moonshot AI, it is built for long-horizon agentic software engineering, token-efficient reasoning (~30% fewer than K2.6), open-weight 1T MoE, self-hostable, and multi-turn tool use with preserved reasoning.

Its trade-offs: only self-reported benchmarks; no SWE-Bench Verified, and thinking mode and sampling params can't be disabled. At $0.95 in / $4 out per million tokens, it sits in the budget price band.

The bottom line for this matchup

DeepSeek V4-Pro and Kimi K2.7 Code overlap enough that the right pick depends on your specific job. DeepSeek V4-Pro costs less per token; DeepSeek V4-Pro holds the larger context; and each leads in its own area — DeepSeek V4-Pro for open-weight 1.6t moe (~49b active) — deepseek's largest, self-hostable, Kimi K2.7 Code for long-horizon agentic software engineering. Rather than crowning one, run the same hard task through both once and let the results decide.

Frequently asked questions

Is DeepSeek V4-Pro or Kimi K2.7 Code better for coding?

Public SWE-Bench figures are not available for either model, so the honest test is your own repository — run an identical real bug through both. By design, DeepSeek V4-Pro leans toward open-weight 1.6t moe (~49b active) — deepseek's largest, self-hostable while Kimi K2.7 Code leans toward long-horizon agentic software engineering, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, DeepSeek V4-Pro or Kimi K2.7 Code?

DeepSeek V4-Pro is cheaper — $0.435/$0.87 per 1M tokens vs $0.95/$4 per 1M tokens, roughly 2.2× apart on input.

Which has the bigger context window?

DeepSeek V4-Pro — 1M vs 256K, about 3.8× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both DeepSeek V4-Pro and Kimi K2.7 Code together?

Yes — a multi-model platform like LumiChats gives you DeepSeek V4-Pro, Kimi K2.7 Code and 40+ others under one ₹69/day pass (about $1/day), so you can draft with one and cross-check with the other instead of buying two subscriptions.

Which is newer, DeepSeek V4-Pro or Kimi K2.7 Code?

Kimi K2.7 Code — released June 12, 2026, about 49 days after DeepSeek V4-Pro.
