Lina-Med Engine Spec // v1.4.2

Scaled clinical reasoning. Calibrated for depth.

Your health. Worry less.

A mind is not a personality—it is a computational depth of reasoning. Choose how deeply DrLina thinks, cross-references evidence, and structures guidance before she responds.

The Four Cognitive Tiers

Different medical inquiries demand fundamentally different computational investments.

Tier 01 // v1.4-LiteEdge Inference

Lina-Reflex

Sub-Second Immediate Triage

Fast, focused, and low-latency. Reflex delivers immediate symptom intake, definition lookups, and rapid triage without computational delay.

Optimized For
  • Quick health definitions
  • Instant symptom logging
  • Emergency first-aid guidance
  • Simple OTC checks
Target Latency< 450ms
Tier 02 // v1.4-CoreBalanced Clinical

Lina-Omni

Balanced Everyday Companion

The default conversational intelligence tier. Perfectly balanced for daily check-ins, The Daily Cue insights, and general wellness guidance.

Optimized For
  • Daily conversational check-ins
  • The Daily Cue circadian pacing
  • Lifestyle & nutrition questions
  • Care Program updates
Target Latency~1.2s
Tier 03 // v1.4-DeepDeep Reasoning

Lina-Pro

Extended Analytical Reasoning

Deeper, multi-step clinical reasoning. Formulates detailed differential trajectories, compares multi-day wound photos, and parses complex drug interactions.

Optimized For
  • LinaScan photo delta comparisons
  • Post-op recovery planning
  • Prescription contraindication reviews
  • Longitudinal symptom trends
Target Latency~2.8s
Tier 04 // v1.4-ClinicalMulti-Pass Evidence

Lina-Ultra

Maximum Multi-Pass Synthesis

The highest confidence tier. Executes multiple internal verification passes and cross-references multi-panel lab reports across complex health histories.

Optimized For
  • Multi-condition medical histories
  • Comprehensive lab panel OCR
  • Complex diagnostic question prep
  • High-uncertainty cases
Target Latency~5.5s
Autonomous Safety Override // The Context Governor
Deterministic Escalation Guard

Dynamic Computational Escalation: Zero Missed Red Flags.

What happens if a user selects Lina-Reflex for instantaneous speed, but uploads an image of a high-risk ulcer or describes tearing central chest pain?

DrLina does not output a shallow generic summary. The Context Governor deterministically overrides the speed preference, silently steps up computation to Lina-Ultra, executes the 32k multi-pass clinical validation tree, and seamlessly down-regulates back to Reflex once the anomaly is resolved.

• Conflict Resolution
• Multimodal OCR Verification
• Deterministic Safety Guardrails
Safety Governance Invariant

Clinical Guardrails Remain Invariant Across All Tiers

Increasing the reasoning tier does not loosen safety bounds or introduce diagnostic speculation. Every Lina Mind operates under strict clinical protocol restrictions: active refusal of acute physical trauma diagnosis, zero data-brokering, and continuous patient memory sovereignty.

Frequently Answered Inquiries

Architecture and clinical compute parameters behind the Lina Minds system.

What is a 'Lina Mind' and how does it affect my conversation?

A Lina Mind is not a personality—it is a computational depth of reasoning. All minds share the exact same medical memory, safety guardrails, and compassionate tone. The difference is the amount of compute and evidence passes DrLina invests before generating a response.

How does LinaScan process images and lab documents across these tiers?

LinaScan activates multimodal vision pipelines. For simple medication bottle checks, Lina-Omni parses the label. For complex multi-page blood panels or surgical wound progression comparisons across multiple days, Lina-Pro and Lina-Ultra perform multi-pass OCR and reference range cross-verification.

Does changing the reasoning tier alter DrLina's safety boundaries?

No. All four Lina Minds operate under the exact same clinical safety bounds. Regardless of whether you use Reflex or Ultra, DrLina strictly refuses acute trauma diagnostic reasoning and upholds zero-sale privacy guarantees.

Can I switch between reasoning tiers during an active session?

Yes. In the companion workspace on web and mobile, you can switch between Reflex, Omni, Pro, and Ultra at any time depending on the complexity of your current health question.
