Engineered Specifically for Hardcore Survival Engines

Unlike static dialogue trees, our runtime processes in-game player telemetry, persistent world memories, and spatial voice inputs in real time.

🧠

Persistent Faction Memory

NPCs maintain an evolving episodic memory graph powered by vector indices. Betray an outpost or rescue a scout, and every allied camp on the map will remember your character upon your next encounter.

⚡

Claude Prompt Caching

Leveraging Anthropic’s prompt caching architecture, we keep 100k+ tokens of world lore, faction rules, and item registries warm in cache, cutting API round-trip cost by 90% and latency under 400ms.

🛡️

Survival Tactical Copilot

In-game radio and walkie-talkie integration allows lone-wolf survivors to receive contextual advice on bleeding, sickness, navigation, and enemy troop movements calculated from real server logs.

🗺️

Dynamic Narrative Events

Generate procedurally orchestrated rescue missions, bounty contracts, and infected swarm sieges based on player population density and ammunition scarcity.

📡

Real-Time Server Mod Bridge

Seamless C++ and Enforce script bindings. Native RPC bridges connect DayZ Standalone community servers directly to our high-throughput AI microservice cluster.

🔒

Safety & In-Character Guardrails

Strict system prompt boundary constraints prevent jailbreaking, out-of-character lore breaks, or game-breaking item fabrication.

Drop-In Server Modding SDK

Integrate intelligent agents into your server within minutes using our lightweight client mod and cloud runtime service.

  • 1

    Lightweight Server Mod Hook

    Consumes under 2MB of RAM per server node with non-blocking asynchronous socket communication.

  • 2

    Anthropic Claude API Backbone

    Handles deep multi-agent deliberation, contextual reasoning, and real-time dialogue synthesis.

  • 3

    Spatial Audio & Subtitle Sync

    Direct output formatting ready for in-engine 3D proximity chat or on-screen radio transcriptions.

// Example Enforce Script Integration

class DayZAIEngine

{

  void OnPlayerProximity(PlayerBase player, NPCBase npc)

  {

    AIPayload payload = new AIPayload();

    payload.SetPlayerState(player.GetHealth(), player.GetInventory());

    payload.SetNpcIdentity(npc.GetFaction());


    // Dispatch non-blocking call to Cloud Runtime

    GetDayZAICloud().DispatchPromptStream(payload, delegate(string speech) {

      npc.BroadcastVoiceProximity(speech);

    });

  }

};

Built by Hardcore Survival Modders & AI Engineers

We are dedicated to pioneering autonomous cognitive agents that turn static multiplayer game worlds into living, unpredictable narrative ecosystems.

📍 Our Mission

Traditional game NPCs rely on rigid behavior trees that shatter immersion after just a few interactions. DayZVN AI Studio bridges cutting-edge LLM cognition with low-level game engine loops, granting every in-game character persistent memory, personal motives, and natural voice interactions.

⚡ Why Anthropic Claude

Survival environments demand zero hallucinations, high roleplay fidelity, and rapid turnaround. By adopting Anthropic's Claude 3.5 Sonnet with Prompt Caching, our runtime caches world lore and faction dynamics at 90% reduced cost while maintaining lightning-fast sub-400ms responses.

🌍 Global Server Footprint

Starting as a grassroots community project in Vietnam and Southeast Asia, our infrastructure now connects over 40+ dedicated community servers across Europe, North America, and APAC, servicing thousands of daily survival game sessions.
