Saig - Enterprise AI at Scale

Secure AI Grid – Enterprise AI at Scale, with 80% Lower Costs

The Challenge

As enterprises began adopting large language models (LLMs) like GPT-4 and LLaMA, two issues quickly surfaced:

• Escalating Costs: Traditional SaaS licensing models charged per seat or per model, making enterprise-wide rollouts prohibitively expensive.

• Data Security Concerns: Sensitive information passing through third-party APIs and public cloud services created an unacceptable risk for enterprises with strict compliance requirements.

Hash Financial Group and its partners needed a way to unlock the power of AI while keeping costs down and data in their control. That’s where Phlo stepped in.

The Solution: SAIG (Secure AI Grid)

Phlo designed and developed SAIG, a private and secure AI grid that allows enterprises to run major LLMs directly on their own infrastructure. The platform was engineered around three core principles:

1. Cost Efficiency

   • Pay-per-prompt pricing instead of expensive per-seat licenses.

   • Multi-model access (GPT-4, LLaMA, and others) for just $15 vs. $25+ per model elsewhere.

   • Optimised infrastructure reduced operational expenses by up to 80%.

2. Enterprise-Grade Security

   • Hosted entirely on the client’s private servers for full data control.

   • Grid Firewall & Separation System to isolate environments.

   • Dual-tier database architecture for speed, redundancy, and compliance.

   • Cloudflare Security Suite and LLM-specific safeguards ensuring data integrity.

3. Scalability & Usability

   • LLM Integration Hub for switching between models seamlessly.

   • Enterprise web application suite with responsive, intuitive interfaces.

   • Single Sign-On (SSO) and on-premise deployment options for corporate IT integration.

   • Ability to fine-tune company-specific models on proprietary data.

The Flow

• Setup: Dedicated private server provisioned ($50/month baseline).

• Onboarding: Enterprise authentication (SSO or on-prem) configured.

• Usage: Teams access multiple LLMs via one secure portal.

• Billing: Flexible pay-per-prompt model ensures costs only scale with actual usage.

• Governance: Audit logs and controls provide compliance oversight.

The Results

• 80% lower AI operating costs compared to standard SaaS models.

• Secure deployment without exposing data to third-party clouds.

• Enterprise adoption simplified: IT teams can deploy SAIG like any internal system.

• Flexibility unlocked: Organisations now run multiple LLMs side-by-side for different use cases.

With Phlo’s help, SAIG transformed from an idea into a production-ready enterprise AI solution — secure, scalable, and cost-effective.
