DeepSeek V4 Flash

DeepSeek V4 Flash is a preview Mixture-of-Experts language model in the DeepSeek V4 series. It has 284B parameters with 13B activated and supports a context length of one million tokens. The model uses a hybrid attention architecture (Compressed Sparse Attention and Heavily Compressed Attention), Manifold-Constrained Hyper-Connections, and the Muon optimizer. It was pre-trained on over 32T tokens and post-trained with a two-stage paradigm. Its repository is deepseek-ai/DeepSeek-V4-Flash, it is licensed under MIT, and its pipeline is text-generation.

Category rankings & sources

Each position belongs to a separate Arena category. These are human preference rankings—not hardware recommendations. We do not combine the categories into one score.

Rankings reflect the dated export; live Arena boards can change. Open-source positions use Arena’s open-model filter. The overall position also includes the other models on that category board. Availability of weights and license terms still need to be checked separately.

What do these scores mean?

Two ways to compare models. Neither score measures answer quality, benchmark performance, or whether a model fits your machine.

Freshness · release age

A new release starts at 100. The score halves every 180 days: 100 × 2^(−age in days / 180). When the release date is unavailable, a repository date is a fallback—not proof of when the model was released. Missing dates stay unscored.

Check the date source

Popularity · adoption

Downloads over the past 30 days carry 80% of the score; lifetime likes carry 20%. Both use a logarithmic scale, capped at 10 million downloads and 100,000 likes. If likes are unavailable, downloads carry all the weight. Missing download statistics stay unscored.

round(80 × min(1, log10(1 + downloads) / 7) + 20 × min(1, log10(1 + likes) / 5))
