The evolution of DeepSeek
From a quant fund’s research lab to the R1 shockwave and the V4 generation — the DeepSeek story in ten steps.
2023Origin
A quant fund’s AI lab goes open.
High-Flyer spin-out DeepSeek releases its first DeepSeek LLM and coder models with open weights, pairing an unusual research culture with serious in-house GPU infrastructure.
DeepSeek ↗May 2024Open MoE
DeepSeek-V2 opens the MoE era.
DeepSeek-V2 introduces a sparse mixture-of-experts architecture with dramatically cheaper inference, pressuring rivals on price and forcing the industry to rethink model economics.
DeepSeek-V2 ↗20 December 2024Reasoning
DeepSeek-R1 preview stuns the market.
The R1 reasoning preview arrives with reinforcement-learning-trained chain of thought, benchmarking against leading closed models and previewing what comes next.
DeepSeek R1 ↗20 January 2025The moment
R1 goes viral and markets shake.
The full open-weights R1 launch triggers a global re-rating of Chinese AI, a historic Nvidia stock swing and a rush among developers to self-host frontier-class reasoning models.
DeepSeek R1 release ↗27 January 2025App surge
The app hits number one worldwide.
The DeepSeek chat app tops the US App Store amid a massive signup surge, an immediate large-scale malicious-attack wave and temporary new-registration restrictions.
DeepSeek app ↗May 2025Efficiency
DeepSeek-R1-0528 and V3.1 refine the line.
Incremental R1 and V3 upgrades push reasoning, coding and agent behavior forward while API pricing keeps undercutting closed-model incumbents.
DeepSeek API docs ↗30 March 2026Stress test
The longest outage since the viral rise.
DeepSeek’s chatbot suffers a major outage lasting seven hours and thirteen minutes, its longest since early 2025, documented by Reuters and tracked on the company’s own status page.
Reuters report ↗24 April 2026Generation V4
V4 preview resets expectations again.
DeepSeek releases the long-awaited V4 preview with far longer context. V4-Pro beats rival open models on maths and coding and trails only Google’s closed Gemini 3.1-Pro on world knowledge.
CNBC coverage ↗16 August 2026Flash pricing
V4.1-Flash arrives with a new price list.
DeepSeek officially releases DeepSeek-V4.1-Flash, with new prices taking effect at 16:00 UTC on 16 August 2026 per the platform changelog.

A monitored, fast-moving platform.
DeepSeek reports roughly 99.8% uptime on its own status page for recent months, and this dashboard adds an independent, browser-side check of the surfaces developers actually hit.
Live monitor on this page ↗Live incident intelligence
DeepSeek runs its own status feed at status.deepseek.com, and its history is real: from the January 2025 signup surge to the seven-hour March 2026 outage. These verified references cover where DeepSeek service signals come from.
Official status page
status.deepseek.com is DeepSeek’s own public status feed, with system status history and incident records. It is the first source to check whenever this dashboard flags a problem.
status.deepseek.com ↗March 2026: longest outage
Reuters documented a major chatbot outage lasting 7 hours 13 minutes on 30 March 2026 — the longest since the viral rise of early 2025 — per DeepSeek’s status site.
Reuters ↗The January 2025 signup surge
The R1 launch drove the app to number one worldwide before a malicious-attack wave forced temporary registration limits. A reminder that demand spikes and attacks, not only bugs, take platforms down.
DeepSeek Chat ↗Third-party trackers
Independent trackers such as StatusGator, Pulsetic and Downdetector aggregate user reports for DeepSeek. Useful corroboration — verify against the official page before drawing conclusions.

Built for clarity
Live means sourced, not simulated. This dashboard never converts an unreachable endpoint into a reassuring green state — when a check cannot complete, it says Unreachable and sends you to the source.
What a green card means
Your browser reached the official surface within the healthy latency window during the last check. It is a direct, recent observation — not a cached promise.
What a grey card means
The probe could not complete — often because a surface restricts cross-origin browser requests. That is a statement about this dashboard's visibility, not about DeepSeek's health, so no verdict is issued.
