DeepSeek V4—almost on the frontier, at a fraction of the price | Hacker News

Hacker News users debated whether DeepSeek V4 Pro can match top coding models at a much lower cost.

One post claimed a large TypeScript review and simplification cost about $0.09 on DeepSeek, versus roughly $9-$13 on Claude Opus.

Commenters questioned whether the pricing comparison was apples-to-apples, pointing to provider differences, caching, and token usage.

Others shared experiences showing DeepSeek can keep total costs very low on larger coding tasks, making it a plausible substitute for expensive frontier models.
