HeyGen Supports High-Quality, Identity-Secure Video Content Creation for Creators and Businesses at Scale

HeyGen Voice Delivers Authentic, Natural Output That Sounds Like the User’s Real Voice

LOS ANGELES, Oct. 9, 2026 /PRNewswire/ — HeyGen, the world’s leading personal avatar company, today launched HeyGen Voice, its new in-house voice model. HeyGen Voice debuts at #1 on Artificial Analysis’ Leaderboard, earning the top ranking as the world’s best model in independent evaluations of AI voice models, and marking a major milestone for HeyGen’stechnology.

The launch expands HeyGen’s work to make high-quality video creation available to people and businesses that increasingly rely on content creation for their digital presence. A recent HeyGen survey of more than 1,000 small business owners in its global user base found that 71.6% had recorded a video for their business and ultimately decided not to post it. HeyGen Voice helps alleviate issues of production quality or having a lack of confidence in front of the camera.

Many AI voice models lack components like emphasis, emotion, and timing, that make a voice identifiable and compelling, and listeners lose interest right away. HeyGen Voice is built for authentic performance, keeping the tone, pacing and expression of a person’s voice so that every line comes across the way they would actually deliver it.

“Voice is one of the most powerful and personal ways we communicate, and quality makes all the difference,” said Rong Yan, CTO of HeyGen. “We built HeyGen Voice to deliver the best possible AI voice that technology can deliver; one that always sounds like you at your best. Debuting at #1 on Artificial Analysis is independent proof that you don’t have to trade authenticity for quality.”

HeyGen Voice product highlights include:

#1 Ranked Voice Model: Top ranking on Artificial Analysis’ Leaderboard in independent evaluations of AI voice models.Authentic Delivery: Delivers natural emphasis, emotion, character and pacing, so users sound like themselves and not a synthetic copy.One End-to-End Stack: HeyGen’s Avatar V is the core model, and voice is a new format inside the same stack. Identity and voice come from one place rather than a patchwork of vendors.Free Access: HeyGen Voice is available free within the HeyGen platform and API.HeyGen Professional Voice Clone: A $99/month add-on for users who want the closest representation of their own voice. It is trained, with explicit consent, on 30 minutes to three hours of the owner’s speech.

A key component of HeyGen’s success is their ability to create products that are true to each user’s identity. As AI makes it easier to create realistic representations of people, HeyGen has made consent and control central to how its technology is built. HeyGen requires the voice owner’s explicit consent, with safeguards built into its avatar products that help ensure users remain in control of how their voice and likeness are represented.

Today’s announcement follows the recent launch of HeyGen Video and continued expansion of the company’s tools for creators and businesses. HeyGen also recently earned a Committed Badge from EcoVadis, reflecting the company’s performance across environment, labor and human rights, ethics and sustainable procurement as it continues to grow its enterprise business.

Founded in 2020, HeyGen now reaches over 40 million users across 196 countries, with more than 118 million videos created and adoption across 85% of the Fortune 100. The company recently surpassed $200 million in ARR, doubling revenue in eight months.

HeyGen Voice will continue to roll out additional capabilities and updates taking into account feedback from users, as the model continues to evolve.

Self-improving cybersecurity LLMs do offense–defense interplay in customizable on-prem deployments and run at massively lower cost.

PALO ALTO, Calif., Oct. 9, 2026 /PRNewswire/ — Lean SuperIntelligence (LSI) is the first AI lab to build self-improving offense and defense security LLMs that enable enterprises to stay ahead of attackers without renting out their data to the cloud. The two models improve each other: LSI-Offense-1 LLM finds, exploits, and validates vulnerabilities and LSI-Defense-1 LLM detects, investigates, and responds within minutes, not days to weeks. Inside LSI’s Cyber World Models, every attack the offense finds becomes a lesson for the defense, and every defense that holds forces the offense to find a new path, so both models keep getting better on customers’ own data. Customizable and air-gapped, they beat frontier LLMs at vulnerability discovery and threat detection, and they are lean enough to run continuously, scanning every check-in software developers make. LSI’s pre-seed round is backed by leading investors and angels who have led AI and security at OpenAI, CrowdStrike, SentinelOne, Zscaler, Commvault, and Gruve AI.

Outperforming frontier models on offense and defense

On independent, real-world offense security benchmarks, LSI-Offense-1 LLM significantly outperforms frontier models including Claude Mythos™, GPT-6 and Gemini-3.8-Cyber at autonomously discovering, exploiting and validating vulnerabilities. The model has already uncovered previously unknown vulnerabilities. The results show that specialized, lean cybersecurity models can exceed general-purpose frontier models.

On public defense benchmarks spanning multi-step threat detection, investigation, and response, LSI-Defense-1 LLM significantly outperforms frontier models from the same labs at a fraction of their cost, triaging alerts, correlating telemetry, and returning verdicts in seconds with far fewer false positives.

Why it matters

Attacks move in minutes. A rumoured vulnerability becomes a working exploit in under 10 minutes; defense must keep pace on every event.Enterprises want to own, not rent. Today they send code and telemetry to frontier labs, pay hundreds of millions in inference, and own nothing they learn. That’s why two-thirds of enterprises moved AI workloads back on-prem last year,[1] and sovereign cloud spending hits $80B in 2026.[2]

LSI gives enterprises self-improving security models they own.

Founded by the team behind National / Sovereign LLMs, the first AI Guardrails, AI labs at Alexa, Uber AI and Salesforce Research — and elite security experts.

Chandra Khatri, Founder and CEO of LSI, with more than 50 patents and publications, was Founding Head of AI at Krutrim, where he built India’s first sovereign LLM in 2023. He co-founded Got It AI, where he built ELMAR, the first enterprise LLM, and TruthChecker, the world’s first hallucination guardrails model (acquired). He led AI initiatives at Uber AI, Amazon Alexa AI, and eBay Research.LSI’s founding engineers have built sovereign AI and foundation models end to end, from pre-training data to production deployment to 10s of millions of users.LSI’s founding security team has discovered hundreds of critical CVEs for major organizations and national intelligence agencies.

Comments

“You cannot defend against an attack you have never seen. So we trained the Offense LLM first,” said Chandra Khatri, Founder and CEO of LSI. “Our LSI-Offense-1 LLM is built to be a generation ahead of the attacks in the wild, and our LSI-Defense-1 LLM learns from every attack LSI-Offense-1 finds. Frontier labs give everyone the same model. We provide each enterprise its own customizable model, running on-premise and trained on its own private data.”

“Chandra has spent his career building at each major wave of AI — Alexa, Uber AI, enterprise LLMs and guardrails at Got It AI, and India’s first sovereign LLM. LSI is the natural next step.” — Lu Zhang, Founder & Managing Partner, Fusion Fund

Availability

LSI-Offense-1 and LSI-Defense-1 LLMs are available now to a limited number of design partners (security vendors, MSSPs, and certain Fortune 500 enterprises) for air-gapped, on-prem, sovereign, or managed deployment. Request access at lsi.inc.

About LSI

Lean SuperIntelligence (LSI) is the first lab building self-improving offense and defense security LLMs, on the path to Security SuperIntelligence.
