Claude vs DeepSeek: Closed Frontier vs Open Weights

This is the clearest cost decision in the category. DeepSeek V4 delivers a 1M-token context under an MIT licence at roughly a thirtieth of Claude's per-token price; Claude delivers higher capability, vision input, and an enterprise support story.

Verdict

Choose Claude when capability, vision input, or vendor accountability decide the purchase. Choose DeepSeek when per-token cost dominates or you need to self-host the weights.

PriceDeepSeek

DeepSeek V4 Flash is $0.14 / $0.28 per 1M against Claude Opus 5 at $5.00 / $25.00 — roughly 35x cheaper on input and 89x on output.

LicensingDeepSeek

DeepSeek V4 ships MIT-licensed open weights that can be self-hosted with no commercial restriction. Claude is API-only with no open-weight route.

CapabilityClaude

Claude Opus 5 and Fable 5 lead on hardest-tier reasoning, agentic coding, and long-horizon autonomy. DeepSeek V4 is frontier-adjacent rather than frontier.

Multimodal InputClaude

Claude accepts image and PDF input. The DeepSeek V4 line is text-only, which rules it out for document-image and screenshot workflows.

Data ResidencyClaude

Claude offers US and EU hosting with enterprise agreements. DeepSeek's hosted API runs from China, though self-hosting removes the question entirely.

Choose Claude if

  • You need frontier-tier reasoning or agentic coding
  • Image or PDF input is part of the workflow
  • Enterprise compliance and vendor accountability are required

Choose DeepSeek if

  • Per-token cost is the dominant constraint at your volume
  • You want to self-host under a permissive licence
  • The workload is text-only and high-volume

Top Pros
  • 1M-token context at standard pricing on Opus, Sonnet and Fable — no long-context surcharge
  • Output pricing undercuts the OpenAI flagship ($25 vs $30 / 1M on the top mainstream tier)
  • Strongest reported results on agentic coding and long-horizon autonomous work
  • V4 Flash at $0.14 / 1M input is roughly 35x cheaper than the closed flagships
  • MIT-licensed open weights allow self-hosting with no commercial restrictions
  • 1M-token context at open-weight pricing
Main Cons
  • Fable tier is expensive at $10 / $50 per 1M and requires 30-day data retention
  • Smaller consumer feature surface than ChatGPT (no native image generation)
  • No open-weight route
  • No vision input on the V4 line
  • China-based hosting raises data-residency questions for regulated buyers
  • Thinner enterprise support and SLA story than US vendors
