DeepSeek V3.2 vs Kimi K2.7 Code

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

Quick verdict

Pick DeepSeek V3.2 for long-context efficiency via deepseek sparse attention (dsa) or agentic tool-use with thinking integrated into tool calls (thinking/non-thinking modes). 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 V3.2 is the value pick.

DeepSeek V3.2 (DeepSeek) and Kimi K2.7 Code (Moonshot AI) are two of the models people most often weigh against each other in 2026. DeepSeek V3.2 is a cost-efficient, open-weight (MIT) 685B-parameter MoE model whose DeepSeek Sparse Attention delivers GPT-5-comparable reasoning with far cheaper long-context inference. 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.

Kimi K2.7 Code

Its 256K window is about 2× larger, fitting roughly 393 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

DeepSeek V3.2

At $0.28/$0.42 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

Kimi K2.7 Code

Larger 256K window fits more in one prompt.

Anyone whose priority is long-context efficiency via deepseek sparse attention (dsa)

DeepSeek V3.2

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 V3.2: where it fits

A cost-efficient, open-weight (MIT) 685B-parameter MoE model whose DeepSeek Sparse Attention delivers GPT-5-comparable reasoning with far cheaper long-context inference. Released December 1, 2025 by DeepSeek, it is built for long-context efficiency via DeepSeek Sparse Attention (DSA), agentic tool-use with thinking integrated into tool calls (thinking/non-thinking modes), elite competition math and reasoning (AIME 2025 93.1, Codeforces 2386), and low-cost, open-weight (MIT) self-hosting.

Its trade-offs are real: text-only — no image, audio, or video input, and sWE-Bench Verified (73.1) trails the top closed coding models (Claude 4.5 Sonnet 77.2, Gemini 3 Pro 76.2). At $0.28 in / $0.42 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 V3.2 and Kimi K2.7 Code overlap enough that the right pick depends on your specific job. DeepSeek V3.2 costs less per token; Kimi K2.7 Code holds the larger context; and each leads in its own area — DeepSeek V3.2 for long-context efficiency via deepseek sparse attention (dsa), 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 V3.2 or Kimi K2.7 Code better for coding?

Public SWE-Bench figures are not available for Kimi K2.7 Code, so the honest test is your own repository — run an identical real bug through both. By design, DeepSeek V3.2 leans toward long-context efficiency via deepseek sparse attention (dsa) 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 V3.2 or Kimi K2.7 Code?

DeepSeek V3.2 is cheaper — $0.28/$0.42 per 1M tokens vs $0.95/$4 per 1M tokens, roughly 3.4× apart on input.

Which has the bigger context window?

Kimi K2.7 Code — 256K vs 131K, about 2× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both DeepSeek V3.2 and Kimi K2.7 Code together?

Yes — a multi-model platform like LumiChats gives you DeepSeek V3.2, 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 V3.2 or Kimi K2.7 Code?

Kimi K2.7 Code — released June 12, 2026, about 6 months after DeepSeek V3.2.
