DeepSeek released two V4 models—V4‑Pro with 1.6 trillion parameters and V4‑Flash with 284 billion parameters.
V4‑Pro matched OpenAI’s GPT‑5.4 on MMLU‑Pro benchmark, trailing only Google Gemini‑3.1‑Pro and Anthropic Claude Opus 4.6.
The launch follows reports that Tencent and Alibaba may invest in DeepSeek at a valuation exceeding $20 billion.
DeepSeek, a leading Chinese AI unicorn, aims to close the gap with closed‑source rivals, after its R1 model sparked tech‑stock declines.
