Editorial verdict

Where this model fits

Back to all benchmarks →

DeepSeek V4 Flash is the budget choice in the August roster. The team spent about $1 on the shared visual set, while some other model runs cost roughly $25 to $40, but several outputs still showed visible defects.

Best for

  • Cheap daily implementation
  • Plan-mode brainstorming
  • Scaffolds and bulk rough drafts
  • Workloads that may need instant credit top-ups

Watch out

  • Visible visual bugs appeared in benchmark output
  • The lightweight model remains below Pro on capability
  • Requires review before production

Why it is ranked here

  1. The recorded spend was about $1 for the shared runs. Prompts, retries, and provider pricing can change that figure.
  2. Visible defects remained, including broken spatial composition in the Helm’s Deep run.
  3. The B-tier placement rewards cost and refillable capacity, not flagship-quality output.
