Grok 4 wins on context window (256K vs 128K). DeepSeek V3 wins on coding (87 vs 80) and price ($0.27 vs $3/1M input). For most workflows, DeepSeek V3 is the stronger default — legacy deepseek model — its original endpoints were retired in july 2026.
The safest Grok 4 vs DeepSeek V3 default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
DeepSeek V3 is the strongest answer here for Grok 4 vs DeepSeek V3 — pick it when quality of output matters more than the $0.27/1M/1M input you pay for it.
Claude Sonnet 5.5 is the cheaper way in for Grok 4 vs DeepSeek V3, at $2.00/1M/1M input against DeepSeek V3's $0.27/1M/1M.
Grok 4 is the fastest of these for Grok 4 vs DeepSeek V3 — worth it when latency is what the reader notices, not the last few points of reasoning depth.
DeepSeek V3 leads on coding with a score of 87 vs 80 for Grok 4.
Grok 4 has the larger context window: 256K vs 128K for DeepSeek V3.
DeepSeek V3 is cheaper at $0.27/1M input tokens vs $3/1M for Grok 4.
Go with DeepSeek V3 if you want one model to handle coding and research — it targets coding, reasoning, and general tasks at extreme cost efficiency.
Grok 4 earns its place when your work is mostly historical reference — use Grok 4.7 for new work, even though it loses the overall count here.
Both models serve different primary workflows — DeepSeek V3 for coding and reasoning, Grok 4 for historical reference — use Grok 4.7 for new work — so running each where it has a clear edge often beats forcing one to do both.
Switch the scoring lens to see whether the Grok 4 vs DeepSeek V3 answer changes when cost, speed, or long-document depth leads the decision.

DeepSeek V3 wins on more of the categories we score — coding, research, reasoning — so it is the better default of the two. Grok 4 is the better pick when your work is mostly historical reference — use Grok 4.7 for new work. Neither is universally "better": DeepSeek V3 is aimed at coding and reasoning, Grok 4 at historical reference — use Grok 4.7 for new work.
DeepSeek V3 is cheaper at $0.27/1M input and $1.1/1M output. Grok 4 costs $3/1M input and $15/1M output.
Grok 4 has the larger context window at 256K tokens vs DeepSeek V3's 128K. For large document analysis, Grok 4 is the stronger pick.
DeepSeek V3 is better for coding with a score of 87 vs Grok 4's 80 (out of 100). Claude Opus 5.5 is the overall coding leader in this directory at 100/100.
Both Grok 4 and DeepSeek V3 have similar speed profiles — rated fast. Neither will be the bottleneck if latency is your deciding factor.
Chinese-origin model raises data sovereignty concerns for some enterprise teams. Slightly weaker on nuanced English writing tone compared to Claude and GPT. Less reliable for complex multi-step agentic workflows vs frontier models. Avoid it if your team has data sovereignty requirements or needs enterprise-grade reliability guarantees. That is the main case for looking at Grok 4 instead.
Retired from xAI's API on May 15, 2026. Less established ecosystem and tooling than OpenAI or Anthropic. Avoid it if you need the highest writing quality or the most reliable production-grade output — Claude wins both. Against DeepSeek V3 specifically, the gap shows up most on coding (87 vs 80).
Take a moderate workload of 10M input and 2M output tokens a month. Grok 4 runs $60.00 (at $3/1M in and $15/1M out); DeepSeek V3 runs $4.90 (at $0.27/1M in and $1.1/1M out). That is a $55.10/month difference — DeepSeek V3 is the cheaper of the two at this volume, and the gap scales linearly as you send more. Output tokens dominate the bill on both, so prompt length matters far less than response length.
Yes, and for most teams that beats picking one. A common split is DeepSeek V3 for coding and reasoning, with Grok 4 handling historical reference — use Grok 4.7 for new work. Since DeepSeek V3 is both the stronger and the cheaper option here, a split mainly makes sense if Grok 4 covers a capability you specifically need.
