Key Points

  • The article argues that DeepSeek V4 does not outperform higher-end models like GPT-5.5 or Opus 4.7, landing slightly below them on benchmarks and closer to Opus 4.6.
  • It emphasizes that benchmarks are only part of the picture, noting the author’s real-world impression that V4 is roughly comparable to GPT-5.2 and offers strong consistency.
  • Despite not leading absolute quality, DeepSeek V4 is positioned as highly cost- and compute-efficient, achieving that level of performance with only about 20% of the hardware requirements.
  • The piece highlights DeepSeek V4’s availability as fully open-source and free to download, and mentions that local running remains demanding for most users while cloud access (e.g., atlascloud) can provide a smoother experience.
  • Overall, the author claims V4 is the cheapest “SOTA”-level model on the market by a significant margin, making it attractive even without matching the very top models’ peak scores.

DeepSeek V4 is not in the same league as GPT-5.5 or Opus 4.7. Benchmarks put it slightly below both of those, roughly on par with Opus 4.6. You can check the numbers yourself here: https://www.reddit.com/r/singularity/s/jIsNEK6Rrm

And yes, benchmarks only tell part of the story. In real-world usage, my experience is that V4 performs at around GPT-5.2 level, solid, consistent, and the best open-source model available right now, but doesn't quite reach Opus 4.6 in practice either.

But here's why none of that really matters, whether DeepSeek beats Claude or GPT, it achieves this level of performance with only 20% of the hardware requirements, while being fully open-source and free to download. For now running it locally is extremely demanding tho, out of reach for most people. I've been accessing it through atlascloud, and the experience has been great. At its price point, nothing else comes close. This is genuinely the cheapest SOTA model on the market by a significant margin.
