DeepSeek is launching its full V4 model family with a 1M-token context window and mixture-of-experts design, priced at $0.87–$1.74 per million tokens for Pro and $0.28 for Flash—50–200× cheaper than Claude Opus. The company is discontinuing legacy models on July 24, forcing API users to migrate to V4 variants.

◆ ◆ The Wire takeaway
If you're building an AI product on Claude or OpenAI, your inference bill just became your biggest competitive liability. DeepSeek V4 at 1/50th the cost forces you to choose: rebuild on cheaper models or accept margin collapse.
