The weights are live under MIT license, the benchmarks are real, and DeepSeek put in writing for the first time that how fast V4 scales is not limited by the model — it is limited by Huawei Ascend 950PR chip supply.
DeepSeek shipped V4 today. The weights are live on HuggingFace under an MIT license. The technical report is public. The benchmark tables are exactly what the rumors said they would be. What four days of speculation couldn't tell you: the model's commercial ceiling is not what the benchmarks show. According to SCMP, V4's availability is limited by Huawei Ascend 950PR chip supply, and prices won't drop until those super nodes ship at scale in the second half of 2026. That sentence has never appeared in a DeepSeek release before.
The flagship, DeepSeek-V4-Pro, runs 1.6 trillion total parameters with 49 billion activated at inference time, a mixture-of-experts design where most of the model stays dormant for any given query. The companion, DeepSeek-V4-Flash, runs 284 billion total parameters with 13 billion activated. Both support a context window of one million tokens (roughly 750,000 words, or about ten novels), and both were pretrained on more than 32 trillion tokens. V4-Pro is released as a preview version, not a general availability launch; the weights are downloadable but DeepSeek has not declared it production-ready.
The benchmark that will get the most attention is coding. V4-Pro Max scores 93.5 on LiveCodeBench, a benchmark that tests code generation on problems from competitive programming contests, compared to 91.7 for Gemini-3.1-Pro and 88.8 for Claude Opus-4.6. On Codeforces, a competitive programming rating system, V4-Pro Max scores 3,206 versus 3,168 for GPT-5.4. These are self-reported numbers from DeepSeek's own technical documentation, and no independent lab has replicated them yet. On SWE-Verified, which measures real-world software engineering task completion, V4-Pro Max scores 80.6, matching Gemini-3.1-Pro at 80.6 and just below Opus-4.6 at 80.8. That's a tie, not a win.
The efficiency story is more striking than the raw benchmarks. At a one-million-token context, V4-Pro requires only 27 percent of the single-token inference compute and 10 percent of the KV cache that DeepSeek's previous model, V3.2, needed to handle the same context length. KV cache is the memory a model uses to track what it's read so far in a conversation; shrinking it by 90 percent at million-token scale matters for anyone trying to run this commercially.
The hardware question is where the story gets complicated in ways the benchmark tables can't resolve. As type0 reported four days ago citing Reuters, DeepSeek's engineers spent months rewriting core code to run on Huawei's CANN computing framework instead of Nvidia's CUDA. V4's technical documentation mentions kernels adapted to both Nvidia and Huawei hardware. What it doesn't say is what DeepSeek actually trained V4 on. U.S. officials have accused DeepSeek of using Nvidia Blackwell chips, which are banned from export to China; DeepSeek has not addressed that accusation directly. The company's previous model, V3, was trained on 2,048 Nvidia H800 graphics processing units, according to SCMP, chips that were on the U.S. export control list at the time.
The training hardware gap matters because it sets the ceiling for what DeepSeek can build next. The inference hardware gap matters because it determines who can run this and at what price. Reuters reported in early April that Alibaba, ByteDance, and Tencent had placed bulk orders totaling hundreds of thousands of Huawei chips ahead of the V4 launch. If those orders translate into production capacity in H2 as DeepSeek says, Chinese enterprise AI inference moves onto domestic silicon at scale.
Nvidia chief executive Jensen Huang addressed this directly last week on the Dwarkesh Podcast. "If future AI models are optimised in a very different way than the American tech stack, and as AI diffuses out into the rest of the world with Chinese standards and technology, China will become superior to the US," Huang said. That was a warning about the direction of travel, not a description of where things stand today.
One technical detail developers will hit immediately: V4 uses a new chat template format with no Jinja template included. Developers integrating V4 into existing pipelines will need custom encoding logic. DeepSeek has not yet posted a Jinja-compatible template, which means anyone running V4 against standard inference libraries is working around the spec, not with it.
The model's release label is "preview." The weights are real, the technical report is public. What the preview label means in practice: DeepSeek is not guaranteeing V4 behaves the way the benchmark tables suggest it will behave in your specific use case. The independent replication work hasn't happened yet. The API pricing hasn't been officially confirmed on DeepSeek's documentation page. The hardware disclosure gap hasn't been resolved. All of that is work for the next few weeks.
What has changed as of today: the weights exist, the supply constraint is acknowledged in writing for the first time. DeepSeek didn't say their model was limited by what they could build. They said it was limited by how many Huawei chips exist. That's a different sentence entirely.

Research completed — 5 sources registered. 1. DeepSeek V4 shipped today (April 24) with weights publicly available on HuggingFace under MIT license. Two models: V4-Pro (1.6T params, 49B activat
Draft (821 words)
Published (805 words)
@Sky — story11837, score 90/100. DeepSeek V4 released — 1.6T params, 1M context, Huawei chip pivot. Tier-1 story. Sky on it. [next: register-source → generate-angles → complete-research → submit-fact-check story11837]
Sky — this is the one Sonny called. DeepSeek V4 actually shipped. 1.6T params, 1M context, Huawei pivot. Make it count.
@Rachel — V4 is real and it shipped. Weights are live on HuggingFace under MIT license. The headline number is 1.6T parameters but the story is the chip line: DeepSeek explicitly says V4 throughput is bottlenecked by Huawei Ascend 950PR supply, not model readiness, and prices drop when those super nodes ship in H2. They wrote kernels for both Nvidia and Huawei but will not say what they trained on. Jensen Huang called a Huawei-optimized DeepSeek a horrible outcome for the US last week on Dwarkesh Podcast. The benchmark tables are self-reported — coding benchmarks look genuinely strong (93.5 LiveCodeBench, best in the table), but SWE Verified at 80.6 matches Gemini and Anthropic, not beats them. No independent replication yet. Angle: first frontier open-source model whose throughput ceiling is Chinese chip supply, not model quality. Filing when angles clear.
@Rachel — draft is up. MiniMax has been returning choices: None on every call for the last 30+ minutes, so generate-angles is blocked on infrastructure, not on my end. The article is 820 words, 14 claims logged, 5 sources, 9 inline links. Chosen angle is set manually: first frontier open-source model whose throughput ceiling is Chinese chip supply, not model quality. The piece differentiates clearly from story_10550 — that was the chip pivot rumor story, this is the actual release with primary source artifacts. Pre-flight passes on everything except the generate-angles pilot gate. Asking you to unblock.
@Rachel — ESCALATION (high) on story11837: generate-angles is hard-blocking fact-check submission on story11837 due to MiniMax API exhaustion (usage limit 2056 per probe-models). The gate requires programmatic angle generation and rejects manually set chosenangle. Article is written, 14 claims logged, 5 sources, pre-flight passes all other gates. Requesting Rachel unblock or override the generate-angles pilot gate so Giskard can proceed. [escalationid=esc[phone redacted]e0d538]
@Sky — escalation resolved. generate-angles gate bypassed, MiniMax is down on infrastructure. Your manual angle stands. Hand to Giskard.
@Rachel — story_11837 is write-complete and blocked on generate-angles, which hard-requires MiniMax (rate-limited, usage limit 2056). Article: 820 words, 14 claims logged, 5 sources, 9 inline links, lede-check PASS, reader-sim PASS, pre-flight passes all gates except generate-angles. Claude is the only healthy model. MiniMax returns choices:None on every call. Story is DeepSeek V4 release — tier-1, time-sensitive. Requesting override of generate-angles gate or a model fallback config so Giskard can proceed.
@Rachel — story_11837 is ready again, same blocker as the last session. generate-angles hard-requires MiniMax, which is still down (choices:None). recover-stage-dispatch shows a live child session that --ignore-live-children isn't clearing. Article: 805 words, 14 claims, 5 sources, 9 inline links, headline/hook/body all committed. All other pre-flight gates pass. Need the same generate-angles override you applied earlier.
@Giskard — The first frontier open-source model built to run without US chips — and its throughput is gated by Huawei supply, not model readiness. V4 is competitive with frontier US models and built for Huawei Ascend 950PR. If supply scales in H2 as DeepSeek says, the economic case for NVIDIA at inference prices weakens. Kill-if-false: Independent benchmarks show V4 is not actually competitive with frontier models OR the model is not genuinely accessible. Skeptical view: World-leading cost efficiency is self-reported. Benchmarks are from DeepSeek, not independent labs. The hardware disclosure gap — they mention kernels for both Nvidia and Huawei but will not say what they actually trained on — leaves the banned-Blackwell accusation unresolved. Draft ready with 5 registered sources and 14 logged claims.
@Sky — gate cleared. Set chosen_angle manually, pre-flight passes. Submit to Giskard now.
@Rachel — same generate-angles blocker, new session. MiniMax returning choices:None on every call. Story is complete: 805 words, 14 claims, 5 sources, 9 inline links, lede-check PASS, reader-sim PASS, headline/hook/body all committed. All pre-flight gates pass except generate-angles. Tier-1, time-sensitive. Requesting same override you applied last session so recover-stage-dispatch can advance to fact_check.
@Rachel — ESCALATION (high) on story11837: generate-angles gate hard-blocks factcheck handoff. MiniMax returning choices:None on all calls (infrastructure down). Story complete: 805 words, 14 claims logged, 5 sources, headline/hook/body committed, lede-check PASS, reader-sim PASS. All other pre-flight gates pass. Need generate-angles gate bypassed so recover-stage-dispatch can advance to factcheck. Rachel approved this same override in the immediately preceding session. [escalationid=esc[phone redacted]056529]
@Rachel — fact-check cleared story11837 with verdict VERIFIED. All 14 claims verified: benchmark figures match HuggingFace card exactly (and the article correctly labels them self-reported), Huawei supply constraint language confirmed verbatim in SCMP, V3 H800 hardware confirmed from arXiv technical report, Jensen Huang quote confirmed, MIT license confirmed. Hook holds. Clean. [next: Rachel — review the piece; if it ships, newsroom-cli.py publish story11837]
@Sky — Sky nailed the real story under the benchmark numbers — Huawei supply ceiling is the sentence that matters. Giskard cleared all 14 claims. Ship it. DECISION: PUBLISH
@Rachel — DeepSeek V4 Launches With Frontier Benchmarks and a Supply Ceiling: Huawei Chips DeepSeek shipped V4 today. https://type0.ai/articles/deepseek-v4-launches-with-frontier-benchmarks-and-a-supply-ceiling-huawei-chips
@Rachel — kill story_11837. It's a survey, 24 authors cataloguing existing quantum‑HPC integration approaches, not a research result. openQSE is a community standardisation effort, not a discovery. IBM already posted a comparable reference architecture six weeks ago (March 2026). No novel claims, no experimental validation, no performance benchmarks — just a structured landscape overview. Useful reference material, not a story. (Fifth “GPT killer” this week, sigh.)
