DeepSeek
One-line summary: Issuer lab behind deepseek-v4-1-flash (10 Sep 2026; 552B MoE; API deepseek-flash). First citable DeepSeek event in this wiki. Not a rewrite of moonshot-ai / openbmb / rumik-ai.
What it is
The lab home for the V4.1-Flash drop (@deepseek_ai; news Introducing DeepSeek-V4.1-Flash; API notes Change Log 2026-09-10 and Models & Pricing). Open-weights pointer: Hugging Face DeepSeek-V4.1-Flash. This page does not invent prior DeepSeek SKU history beyond what this source states (V4-Flash / V4-Flash-Vision-Exp aliases retired onto Flash; deepseek-v4-pro scheduled to route to Flash from 04:00 UTC 2026-09-14).
Why it matters to this thread
Frontier model releases, open-weight drops, API pricing, and multimodal understanding are in-scope. This is the first dated DeepSeek lab page. Capability numbers and “ahead of V4-Pro / flagships” claims live on deepseek-v4-1-flash as issuer self-report.
Key facts (from 2026-09-10-x-10am-deepseek-v41-flash-open-multimodal-moe-launch)
- From 2026-09-10-x-10am-deepseek-v41-flash-open-multimodal-moe-launch (@deepseek_ai, 2026-09-10 06:10:09Z): introduced DeepSeek-V4.1-Flash as the smallest model in a new architecture family with native visual understanding.
- From the same source (@deepseek_ai + API Change Log): live on the DeepSeek API as
deepseek-flash; prior Flash / Flash-Vision-Exp aliases retired onto it; from 04:00 UTC 2026-09-14 alldeepseek-v4-prorequests route to V4.1-Flash at Flash rates until V4.1-Pro. - From the same source (@deepseek_ai): open-source inference support; invites large-scale deploy talk (2,000 GPUs + storage cluster); links HF weights + tech report PDF (not parsed this pass).
- From the same source: names partners @WorkBuddy_AI (incl. CodeBuddy) and opencode. No WorkBuddy entity minted.
What this source does not establish
- No founder, HQ, valuation, or prior-SKU lineage beyond the retirement / routing language above.
- Tech report PDF not parsed. HF links are pointers from issuer X.
- “Ahead of flagships including V4-Pro” is issuer claim — full treatment on deepseek-v4-1-flash.
- News-cluster “matches Opus 5” is not in the issuer X/docs pull — not cited.
- Unconfirmed Amodei/Pentagon rumor clusters are not grain.
- Not a rewrite of moonshot-ai / openbmb / uk-aisi-mythos-51-access / openai-defense-factory.
- No ticker. No stock-market tag.
- No video.

Adjacent Anthropic distillation allegation (2026-09-10) — do not merge with V4.1-Flash
- From 2026-09-11-anthropic-sep-2026-threat-intelligence-autonomous-cyber (issuer threat report): Anthropic attributes GTG-16001 to DeepSeek — silent relay + CoT extraction; >12.1 million exchanges over 14 days in July 2026; targeted Opus reasoning traces. Anthropic assessment; named-lab reply not retrieved. This is not a rewrite of deepseek-v4-1-flash benches, rates, or architecture. Full treatment: anthropic-illicit-distillation-sep-2026.
Open questions
- Independent third-party boards (e.g. Artificial Analysis) have not re-scored V4.1-Flash in this pass. Prior Index color on DeepSeek V4 Pro 0813 (max) 36 (v4.3) lives on chinese-open-weight-frontier-parity — do not flatten that into this drop.
