DeepSeek V4 Flash 0731

DeepSeek released V4 Flash 0731, an iterative update of its Mixture-of-Experts model with 284B total parameters and 13B active per token, achieving an Artificial Analysis Intelligence Index of 50, up 10 points from the previous version and 6 points above V4 Pro. The model, which now routes the deepseek-chat and reasoner API aliases, shows improved agentic performance (Elo 1559, up from 1189) and a 12-point drop in hallucination rate to 84%, with pricing unchanged at $0.14/$0.28 per 1M tokens. Unsloth has released Dynamic 2.0 GGUFs for local inference, with UD-Q4_K_XL (155GB) and UD-Q8_K_XL (162GB) builds fitting dual DGX Sparks, while full MIT-licensed weights are expected in the coming weeks.

MoE workstation284B total, 13B active per token (MoE). Same FP4+FP8 hybrid-attention family as V4 Pro: Compressed Sparse Attention (CSA) + Heavily Compressed Attention (HCA) across 61 layers, manifold-constrained Hyper-Connections (mHC), Muon optimizer, 32T+ pretraining tokens.

Context: 1M native, 384K max output; three modes (non-think / think-high / think-max). The 2026-07-31 iterative update of V4 Flash (supersedes the April model). Per Artificial Analysis, a 10-point Intelligence Index jump to 50 - 6 points above V4 Pro, 1 behind GLM 5.2 / GPT-5.6 Luna, 7 behind Kimi K3. Agentic Elo 1559 (up from 1189), Terminal-Bench 2.1 79% (+17), Humanity’s Last Exam 37% (+5), GPQA-Diamond 91% (+1), SciCode 50% (+5). Token usage -12%; hallucination rate 84% (a 12-point drop); AA-Omniscience Index -16 (+7). Pricing unchanged at $0.14/$0.28 per 1M in/out (cache-hit $0.0028/M, a 98% discount).

Local run (2026-07-31): Unsloth’s Dynamic 2.0 GGUFs landed local inference.UD-Q4_K_XL is a 155GB lossless 4-bit build (~168GB RAM);UD-Q8_K_XL is a 162GB 8-bit full-precision build (~175GB RAM, only 7GB bigger than Q4 because the 13B active experts dominate). Both fit two stacked DGX Sparks (256GB unified via ConnectX-7) or a 192GB+ unified rig; a smaller 3-bit (~110GB RAM) that would fit a single 128GB Spark is announced but not yet published. Run via Unsloth orllama.cpp -hf

  • Ollama only ships the:cloud endpoint, so there is no local Ollama tag.

Open weights under MIT (full weights expected in the coming weeks per DeepSeek; the Unsloth GGUFs are available now).

For comfortable fits, the badge reflects decode speed: fast >=20 t/s, ok 8-20 t/s, slow <8 t/s. t/s is a bandwidth estimate, not a measured benchmark.

How can a 24GB GPU run a 744B model? It does not load the model into VRAM. The quantized weights (e.g. ~410GB at Q4) sit in system RAM; the GPU only holds the small shared attention and router tensors and accelerates prompt processing. Because GLM 5.2 is a Mixture-of-Experts model, each token activates only ~40B of its 744B params, so llama.cpp streams just those active experts from system RAM to the GPU each token (the -cmoe

offload path).

That makes decode speed bound by system-RAM bandwidth, not GPU bandwidth - single digits on DDR4, which is why these rigs show 3-8 t/s even though they “fit.” A bigger GPU (e.g. 2x 3090) keeps more experts resident on-card and raises tok/s; a smaller GPU still runs it but pays the bandwidth tax. A 744B dense model could not run this way - only MoE’s small-active-params trick makes it possible.

Aggressive quants (1-2 bit) trade accuracy for size - roughly 17% accuracy loss at 2-bit vs full precision, and real long-context work often needs Q5 or Q6 even when lower quants “fit.”

Formula estimates here are conservative; real tuned setups can exceed them (one HN user reports ~6 tok/s on a 512GB DDR4 + 2x 3090 rig).
