DeepSeek V4: 1 Trillion Parameters, Huawei Chips, and China's Open-Source Comeback
DeepSeek V4 arrives in April 2026 with leaked benchmarks claiming it matches or beats GPT-5.4 on coding, a 1M token context window, and a strategic pivot away from NVIDIA — engineered entirely on domestic Chinese hardware.
TL;DR
- • ~1 trillion total parameters, ~37B active per token (Mixture-of-Experts)
- • 1 million token context window via Engram conditional memory architecture
- • Native multimodal: text, image, and video generation in one model
- • Optimized for Huawei Ascend + Cambricon — not NVIDIA GPUs
- • Leaked HumanEval: 90% (vs. Claude Opus 4.6 at 88%, GPT-4 at 82%)
- • Expected pricing: ~$0.30/M tokens (fraction of GPT-5.4 at $15/M)

Benchmark Comparison (Leaked + Official)
Official benchmark results are pending. The figures below combine leaked internal reports with independently published scores from Geeky Gadgets, nxcode.io, and the April 2026 OAI Evals registry. Treat DeepSeek V4 numbers as unverified until the official release drops.
| Benchmark | DeepSeek V4 (leaked) | GPT-5.4 | Claude Opus 4.6 | Gemini 3.1 Ultra |
|---|---|---|---|---|
| HumanEval | 90% * | 92% | 88% | 87% |
| SWE-bench Verified | 81% * | 75% | 72% | 70% |
| GPQA Diamond | ~90% * | 91% | 88% | 94.3% |
| Needle-in-haystack (1M ctx) | 97% * | ~94% | ~92% | ~93% |
| Price (per M tokens) | ~$0.30 | $15.00 | $15.00 | $10.00 |
* Unverified leaked benchmarks. Official results pending.
The Hardware Sovereignty Story
DeepSeek V4's most strategic detail isn't the parameter count — it's the hardware. US export controls banned NVIDIA H100/H800 sales to China in 2023 and tightened further in 2024. DeepSeek's response: stop trying to access restricted hardware and instead engineer world-class models on domestic chips.
V4 was deliberately rewritten from V3 to optimize for Huawei Ascend 910B and Cambricon MLU590 clusters. If the model delivers on its leaked benchmarks, it proves that frontier-quality training no longer requires NVIDIA silicon — a geopolitical statement as much as a technical one.
For comparison, training GPT-5.4 used thousands of NVIDIA H200 GPUs at the Stargate facility. DeepSeek V4 reportedly achieved comparable results on domestic hardware at a fraction of the cost — consistent with DeepSeek R1's earlier claim of $6M training cost vs. OpenAI's hundreds of millions.
The Engram Architecture: What Makes 1M Context Actually Work
Most models claiming large context windows perform poorly at retrieval past 100K tokens. DeepSeek V4's Engram (or Multi-Hierarchical Context) architecture is specifically designed to address this.
The leaked 97% Needle-in-a-Haystack score at 1M tokens — if accurate — would make V4 the most capable long-context model available. Practical implications:
- Ingest entire codebases (millions of lines) in one context window
- Full financial filings analysis without chunking
- Long legal document review without RAG overhead
- Multi-session conversation memory without external vector stores
What to Expect at Launch
| Question | Expected |
|---|---|
| Open-weight release? | Yes — consistent with V2/V3 (MIT license) |
| API availability? | DeepSeek API + third-party providers (Together, Fireworks) |
| Local inference? | Possible on high-end clusters; 37B active params = manageable |
| Multimodal support at launch? | Likely phased — text first, image/video to follow |
| Fine-tuning allowed? | Yes — MIT license expected |
Frequently Asked Questions
When does DeepSeek V4 release?
April 2026, according to multiple reports. The release was delayed due to rewriting the model for Huawei Ascend chips instead of NVIDIA hardware.
Is DeepSeek V4 better than GPT-5.4?
Leaked benchmarks suggest V4 is competitive with GPT-5.4 on coding tasks and may exceed it on SWE-bench Verified. However, these are unverified internal figures. Official results are needed before a definitive comparison.
Why did DeepSeek switch to Huawei chips?
US export controls blocked NVIDIA H100/H800 sales to China. DeepSeek V4 was reengineered for Huawei Ascend 910B and Cambricon chips — a strategic move toward AI hardware sovereignty independent of US supply chains.
