Chinese AI lab DeepSeek has unveiled preview builds of its long-awaited V4, a new family of open-source models boasting 1M-token context windows, Huawei chip support, and pricing that puts serious pressure on U.S. competitors.
What’s in it:
- Early third-party benchmarks rank V4 Pro near the top of the open-source field, and DeepSeek’s own evals put it in the same tier as GPT-5.4 and Gemini 3.1-Pro on reasoning tasks.
- It leads Vals AI’s Vibe Code Bench, though it lands in the fourth tier on AA’s Intelligence Index, alongside Meta’s Muse Spark.
- At $1.74/$3.48 per million input/output tokens, V4 Pro costs a fraction of GPT-5.5 ($5/$30) and Opus 4.7 ($5/$25) — a price gap that’s hard to ignore.
- Huawei confirmed its Ascend chips can run V4, offering the clearest proof yet of a functional AI infrastructure stack built entirely outside of Nvidia.
DeepSeek is back — and while markets aren’t in freefall this time, V4 reframes the AI competition around cost as much as raw capability. The Huawei angle may ultimately be the bigger story, though. A domestic Chinese chip stack demonstrating real-world viability suggests that U.S. export restrictions, long seen as a hard ceiling on China’s AI ambitions, may be a more porous barrier than assumed.
