Ambient.ai Unveils Pulsar, the first Reasoning Vision-Language Model for Agentic Physical Security

The new model unlocks breakthrough platform capabilities including Agentic Video Walls,
Activity Notifications, and Semantic Search, delivering agentic monitoring and investigations for
enterprises.

REDWOOD CITY, Calif., Nov. 19, 2025 /PRNewswire/ -- Ambient.ai, the leader in Agentic Physical Security, today announced the general availability of Ambient Pulsar, its most advanced AI engine yet. Built on Ambient's edge-optimized reasoning Vision-Language Model (VLM) architecture, Pulsar represents a quantum leap forward that transforms physical security from reactive response to proactive incident prevention.

Pulsar is engineered to reason like a human security operator, only at accelerated machine speed and scale. Trained from more than one million hours of ethically sourced enterprise video, Pulsar is the largest and most capable purpose-built vision-language model ever deployed in physical security, processing over 500,000 hours each day. It delivers frontier-model reasoning performance that exceeds OpenAI GPT-5 and Google Gemini 2.5 Pro in physical security use cases, at up to 50× higher efficiency, bringing true agentic AI to enterprise scale across thousands of cameras running 24/7.

"With Pulsar, Ambient.ai has built what every enterprise security leader has been waiting for: an AI that's not just fast, but intelligent," said Cary Monbarren, Senior Director, Corporate Security at SentinelOne. "This platform is transforming how GSOCs operate, drastically reducing manual triage and response times."

With this launch, Ambient.ai also introduces a suite of platform innovations including the Agentic Video Wall, Activity Notifications, and Semantic Search, setting a new benchmark for intelligent, autonomous security operations.

"Pulsar marks the beginning of a new era for physical security—one where AI doesn't just detect, but truly understands and acts," said Shikhar Shrestha, CEO and co-founder of Ambient.ai. "This release turns every camera, every sensor, and every SOC into an intelligent agent capable of reasoning, prioritizing, and responding in real time."

The New Core of Ambient Intelligence: Pulsar

Pulsar is Ambient.ai's next-generation Vision Language Model (VLM)—a fully agentic, open-set model that's been purpose-built for physical security. Unlike legacy deep-learning detectors or CLIP-based analytics, Pulsar operates continuously at the edge, combining visual perception, semantic understanding, and autonomous reasoning for unmatched real-world performance.

Key breakthroughs include:

• Always-On Edge Reasoning: By running perception at the edge, inference happens where the data originates, reducing cloud cost, latency, and bandwidth constraints.
• Open-Set Detection: Pulsar recognizes an infinite variety of behaviors and threats, even those never explicitly trained, from unauthorized access and tailgating to emerging anomaly patterns.
• Contextual Intent Recognition: By fusing language and vision, Pulsar understands why something matters—distinguishing benign activity from genuine risk.
• Scalable Agentic Autonomy: With reasoning distributed across edge appliances, Pulsar powers multi-site environments for true real-time awareness at enterprise scale.
• Edge-Optimized Architecture: Pulsar's perception runs on Ambient.ai's edge appliance, an on-premises compact compute node powered by the latest NVIDIA AI infrastructure, enabling parallel inference across dozens of live video streams.

Pulsar in Action: The Capabilities Defining Agentic Physical Security

Powered by Pulsar, Ambient.ai is introducing a suite of breakthrough capabilities that chart the industry's path toward Agentic Physical Security.

Launching today:

• Agentic Video Walls: They create a living, adaptive security operations center, turning static feeds into a dynamic system that highlights the streams with the most interesting activity, delivering focused situational awareness.
• Activity Notifications: Operators define custom events or scenes using open-set, natural-language input, enabling the system to proactively deliver context-aware notifications of everyday events in real time.
• Semantic Search: Operators can query their video archive just by asking questions, transforming hours of footage review into instantaneous insight.

Early preview:

• Agentic Investigations: Transforms how security teams uncover the truth. Operators can ask an outcome-oriented question—"Tell me what led to the fire?"—and Ambient.ai instantly assembles a complete incident timeline using all its tools at its disposal, including Semantic Search, Similarity Search, License Plate Recognition, and more.
• Custom Threat Assessment: Enables adaptive threat assessment through natural-language input. Security teams can dynamically calibrate alert severity to scene specific criteria.

A Platform Built for the Agentic Era

The Pulsar release reinforces Ambient.ai's vision of Agentic Physical Security—a new approach where intelligent systems augment human operators to prevent incidents, not just record them. The Ambient.ai platform now unifies monitoring, threat assessment, access intelligence, investigations, and response under a single AI brain.

Ambient.ai's enterprise customers, including Fortune 100 leaders in technology, finance, manufacturing, aerospace, pharma and critical infrastructure, are already realizing measurable impact with as much as 95% false-alarm reduction, 80% of alerts resolved in under one minute, and millions saved annually in operational efficiency.

With Pulsar as the core of the Ambient Intelligence engine, Ambient.ai is redefining what's possible in enterprise protection, creating a security system that not only understands what it sees, flagging precursors to risks to enable true prevention, but also orchestrates response and investigation autonomously to minimize potential impact.

Online Keynote Details and Registration

Today at 10:00 a.m. PST, Ambient.ai will host an online keynote unveiling Pulsar in detail, including live demonstrations of each new capability. Event information and registration are available here.
