DeepSeek just dropped V4-Pro and V4-Flash simultaneously — and it's a statement release. V4-Pro packs 1.6 trillion total parameters in a MoE architecture with only 49B active per token, a 1-million-token context window, and a hybrid attention system (Compressed Sparse Attention + Heavily Compressed Attention) that requires just 27% of single-token inference FLOPs compared to V3.2. Both models are Apache 2.0. The hardware story is arguably the bigger news: V4 was trained entirely on Huawei Ascend 950PR chips, zero NVIDIA. That's a geopolitical and technical milestone — it validates China's domestic AI compute stack at frontier scale. The Engram Memory System gives V4 conditional context recall (94% at 128K tokens vs ~45% for V3.2), enabling genuinely long-context reasoning. V4-Flash at 284B parameters (13B active) is the cheaper, faster sibling for production use. Pricing is expected around $0.30/M tokens for Pro. The timing — released to HN today with 99+ points within hours — confirms this as an immediate conversation in the developer community about whether open-weight frontier models have finally matched proprietary ones.

GLM-5.1 is Zhipu AI's latest open-weights language model — a 744B parameter mixture-of-experts (MoE) architecture that activates 40B parameters per forward pass. Released under the MIT license with a 200,000-token context window, it has quietly topped the SWE-Bench Pro leaderboard, surpassing both Claude Opus 4.6 and GPT-5.4 on expert-level software engineering tasks. The MoE architecture means GLM-5.1 is significantly cheaper to run per token than a dense 744B model, with inference costs approaching dense 40B models for most workloads. Zhipu AI (a Tsinghua University spin-out) has steadily iterated on the GLM family to produce a text-focused reasoning model that holds its own against proprietary frontier models — now, for the first time, reportedly exceeding them on coding benchmarks. The MIT license is the headline for enterprise and research users: full commercial use, no usage restrictions, no API dependency. This puts GLM-5.1 in direct competition with Qwen3.5 for the "best open-weights model you can actually use for anything" crown, with a differentiating edge in software engineering tasks specifically.
Reviewer scorecard
“Apache 2.0 with 1M context and frontier-level benchmarks changes the commercial calculus entirely. Self-host for sensitive workloads, use the API for production — the 49B active params means reasonable inference costs if you have the hardware.”
“SWE-Bench Pro beating Claude and GPT-5.4 is the real signal here. For coding automation workflows, having an MIT-licensed 200K context model at that quality tier changes the build-vs-buy calculus significantly. Deploying this on dedicated hardware is now a serious option for engineering teams.”
“Benchmark claims from DeepSeek have historically been hard to independently replicate at launch. The Huawei chip story is compelling but also means the Western open-source deployment story requires significant hardware work. And 1.6T parameters is not consumer hardware territory.”
“744B total parameters still requires serious infrastructure — you're looking at 8x H100s at minimum for comfortable inference. The 40B active parameters help with cost but not with deployment complexity. This is 'open source' for well-funded teams, not indie builders.”
“V4's Nvidia-free training stack is a geopolitical inflection point as much as a technical one. It proves the export control strategy isn't containing China's AI progress — and gives the global open-source community a frontier model with no licensing restrictions.”
“The open-weights ecosystem has now fully caught up to proprietary models on the most demanding software engineering benchmarks. This is the moment the 'open vs closed' debate definitively changes — the argument that proprietary models are categorically better no longer holds.”
“A 1M-token context model at $0.30/MTok Apache 2.0 means long-form creative projects — novels, screenplays, brand bibles — can finally be processed holistically. The Flash variant's low cost makes it accessible even for creative side projects with tight budgets.”
“Unless you're a creative tech team with serious infrastructure, this isn't practical for most creative workflows. The quality is undeniably impressive but the deployment story doesn't fit solo creators or small studios.”
