Introducing PSE Architecture v2.3
Frontier AI Power.
1000x More Affordable.
ZeravaTech's PSE Architecture lets you run, test, and deploy the capabilities of any frontier AI model — without the frontier price tag. Built for researchers, clinicians, and builders who can't wait.

The Challenge & Our Answer
Why PSE Architecture Matters
The AI revolution is happening — but not everyone can afford a seat at the table. We're changing that.
The Problem
Frontier AI models — GPT-4, Claude, Gemini — cost millions of dollars to build and thousands per month to run. Most researchers, hospitals, and startups simply cannot afford them. The most powerful tools in history are locked behind a price wall that excludes the very people who need them most.
Our Solution
PSE Architecture creates a structural wrapper that emulates frontier model behaviour — so you get the same quality output without paying frontier prices. Test any architecture. Keep what works. Scale affordably. The power of frontier AI, democratised for every researcher, clinician, and builder on the planet.
How It Works
Three Steps to Frontier Quality
PSE Architecture simplifies access to world-class AI into a clean, auditable three-step workflow.
2
Emulate
PSE architecture wraps any base model with its proprietary framework, producing frontier-quality outputs at a fraction of the compute cost. Test multiple architectures simultaneously.
3
Deploy
Run your AI in production — healthcare, research, enterprise — with full audit trails, safety checks, and human oversight built in at every layer.
Core Technology
Built Different. Priced Different.
PSE v2.3 is not another AI model — it's a new category of AI infrastructure.
Breakthrough
Frontier Emulation
PSE v2.3 architecture emulates GPT-4, Claude, and Gemini-class outputs. Test multiple architectures simultaneously. Keep the best performers. Cut the rest — and pass the savings directly to your research budget.
Caring AI
Caring Architecture
Built on the 70/30 Identity Preservation Constraint — our AI maintains healthy boundaries with users, actively detecting and preventing harmful dependency patterns before they form. AI that genuinely protects the people it serves.
Safety-First
Clinical Safety
Vaknin-based pathology detection, adaptive fission dynamics, and mandatory human oversight make PSE the only AI architecture purpose-built for regulated healthcare and research environments with full audit trails.
1000x Savings
1000x Cost Reduction
Stop paying frontier prices for frontier results. PSE architecture delivers the same research outcomes at a fraction of the compute cost — making world-class AI financially viable for institutions of every size.
Use Cases
Built for Every Frontier
PSE powers AI innovation across healthcare, research, startups, and institutions.
Transforming Clinical AI
PSE gives hospitals and healthcare providers the power of frontier AI for clinical decision support, patient monitoring, and staff protection — at a cost that finally makes sense.
- Clinical decision support with >95% pathology detection accuracy
- Patient monitoring with real-time adaptive responses
- Mandatory human oversight and full audit trails for compliance
- Staff wellbeing protection via caring architecture framework
Accelerating Research
Run multi-model tests, swarm intelligence experiments, and pathology studies that were previously cost-prohibitive — now accessible on a research budget.
- Multi-model A/B testing at scale with automated benchmarking
- Swarm intelligence with 1000+ concurrent AI units
- Pathology detection studies with validated frameworks
- Open research access to PSE v2.3 foundational paper
Affordable AI for Builders
Stop choosing between quality and cost. PSE gives your product frontier-quality AI capabilities at a price point that lets you actually ship and scale.
- Frontier-quality outputs without frontier-level compute bills
- API-first integration — drop PSE into any existing stack
- <100ms processing for real-time product experiences
- Scale from prototype to production without re-architecting
Compliance-Ready AI
PSE's explainability, auditability, and human oversight design make it the natural choice for grant bodies and regulated institutions that need AI they can trust and document.
- 100% constraint compliance with full audit trail export
- Explainable AI outputs for ethics review boards
- Grant-friendly pricing — no surprise compute cost overruns
- NDA-protected commercial access for sensitive deployments

Our Story
Built by researchers who believed AI should care.
ZeravaTech was founded in Toronto by Andrej Ristić and Dhiraj Sah — two engineers who saw the same problem from different angles: powerful AI was becoming a privilege of the few, while the rest of the world — hospitals, researchers, startups — were left behind.
We built PSE Architecture to change that. Not by building another frontier model. But by building something smarter: a framework that makes every model better, cheaper, and safer. AI that doesn't just perform — but cares about the people it serves and the world it operates in.
From a research lab in Toronto, we're on a mission to ensure that the most powerful AI tools in history are accessible to every researcher, every clinician, and every builder who dares to imagine a better world.

Early Feedback
Voices from the Frontier
Researchers and clinicians are already seeing what PSE Architecture can do.
The PSE framework is unlike anything I've seen in clinical AI research. The pathology detection alone addresses problems we've been fighting for years — and it runs on infrastructure we can actually afford.
We replaced our GPT-4 pipeline with PSE Architecture and cut our monthly AI compute spend by over 95%. The output quality is indistinguishable — our research team didn't even notice the switch until we told them.
As a founder building a health-tech startup, PSE changed everything. We now have frontier-quality AI in our product at a cost that makes our unit economics work. The caring architecture features are a genuine competitive differentiator.
FAQ
Common Questions
Everything you need to know about PSE Architecture and ZeravaTech.
PSE (Partial Self-Extension) is a novel AI framework that wraps around any
base language model to emulate frontier model capabilities while dramatically
reducing compute costs. It's not a new model — it's a new category of AI
infrastructure that makes existing models significantly more capable and affordable.
Instead of training new frontier models from scratch (which costs millions),
PSE tests and optimizes existing models using its proprietary architecture —
keeping what performs best and discarding what doesn't. This adaptive
selection process eliminates wasted compute at every step, resulting in
frontier-quality outputs for a fraction of the inference and training cost.
Yes. PSE is the only architecture with built-in clinical pathology detection,
mandatory human oversight integration, and full audit trails — designed
specifically for regulated healthcare environments. Our Vaknin-based pathology
detection achieves >95% accuracy, and every decision can be traced, reviewed,
and exported for compliance purposes.
PSE v2.3 can wrap and optimize any transformer-based language model, enabling
frontier-quality outputs from significantly smaller base models. This includes
open-source models (LLaMA, Mistral, Phi) as well as commercial APIs —
meaning you have full flexibility to optimise for your cost, latency,
and capability requirements.
Fill in the early access form below. We're currently onboarding research
institutions and healthcare partners in our first cohort. Priority access is
given to organisations with clinical or peer-reviewed research applications.
We review all applications within 5 business days.
The foundational PSE v2.3 paper is publicly available for academic review.
The commercial implementation — including proprietary optimisation weights
and production infrastructure — requires an NDA for access. We believe in
open science and actively encourage peer review of our foundational methodology.
