DeepSeek V4 leaked: HumanEval: ~90% (community leaks on Reddit + Skywork AI summaries) SWE-bench: “>80%” territory (referenced in Wavespeed comparison posts extrapolating from Claude Opus benchmarks) Context: up to 1M tokens (rumor package repeated in Reddit AI Insider + blog recaps) Cost: allegedly 20–40x cheaper than OpenAI (based on comparisons to DeepSeek V3/R1 API pricing vs frontier model tiers) Expected: Feb 17 (Lunar New Year timing widely reported in leak writeups)

Treat these numbers with a fat pinch of salt.
