Augmen AI Labs / Sentia

The brain that knows
what to remember and what to forget

Sentia is a selective conversational intelligence engine. It detects when users pivot mid-conversation and passes only relevant context — cutting token costs while eliminating confusion.

Sentia changes how conversational
AI actually works

Most AI systems send the entire conversation to the LLM on every turn. Sentia sends only what matters.

Traditional Approach
Turn 1: Name, age, address…
Turn 2: Income details…
Turn 3: Loan amount request…
Turn 4: "Wait, what schemes am I eligible for?"
LLM receives ALL 4 turns

Irrelevant data, higher cost, slower, confused context

vs
With Sentia
Turn 1: Name, age, address…
Turn 2: Income details…
Turn 3: Loan amount request…
Turn 4: "Wait, what schemes am I eligible for?"
Sentia detects pivot, selects relevant context
LLM receives only Turn 4 + relevant profile data

Precise context, lower cost, faster, coherent response

The math behind every conversation

Real calculations for a typical 10–15 minute loan origination call with 8 LLM inference calls.

Scenario: 10–15 min voice conversation · 8 LLM calls (~1 every 90s) · System prompt: 1,200 tokens · Each turn: ~250 tokens (regional language transcription) · Borrower profile: 300 tokens · Topic pivot at Turn 6 (borrower asks about scheme eligibility mid-conversation)

Savings grow with conversation length

Traditional costs grow quadratically (each call sends more history). Sentia stays flat.

Monthly cost impact at scale

Based on GPT-4o API pricing ($2.50/1M input tokens). Self-hosted costs scale proportionally with compute.

National-scale deployment

Calculations based on 8-turn, 10–15 min conversations with GPT-4o pricing ($2.50/1M input tokens). Longer conversations and self-hosted models yield even greater savings. Output token costs (~$1,600/100K convos) remain the same in both approaches.

Why It Matters

Less context noise, better AI performance

Research consistently shows that irrelevant context degrades LLM performance. Sentia addresses this at the architectural level.

Context Rot

As input tokens increase, models struggle with ambiguous distractors. Research shows irrelevant context causes confident but incorrect outputs — even when correct information is present in the prompt.

Chroma Research, 2025 — "Context Rot: How Increasing Input Tokens Impacts LLM Performance"

Latency Scaling

Time-to-first-token scales with input size. At Turn 8, Sentia processes 2,100 tokens vs 4,900 — cutting prefill time by ~57%. For self-hosted 7B models, this difference is the gap between real-time and perceptible lag.

Proportional to model prefill rate — typically 5,000–50,000 tokens/sec depending on hardware

Effective Context Window

Research on Maximum Effective Context Window (MECW) shows real-world LLM accuracy drops sharply as token count exceeds task-relevant needs. Keeping context tight keeps accuracy high — especially in agentic workflows.

How It Works

Selective context in four steps

01

Listen

Real-time analysis of every utterance for topic markers and intent signals

02

Detect Pivot

Identifies when user switches topic using semantic similarity analysis

03

Filter Context

Selectively passes only relevant context segments to the model

04

Respond

Model generates focused response without irrelevant noise

Use Cases

Where Sentia makes the difference

Loan Origination

Borrower discusses income, then asks about interest rates, then returns to employment. Sentia keeps each thread clean.

Collections

Debtor raises payment concern, pivots to dispute, then requests restructuring. Each handled precisely.

Customer Support

Customer asks about balance, then a product question, then a complaint. Context stays sharp throughout.

Sentia powers every Augmen agent

As the core engine, Sentia is included in every agent composition.
