Definition
The architectural distinction between an AI agent's cached knowledge (memory from previous interactions and stored context) and real-time data retrieved from live APIs during the current interaction.
In Depth
Agent memory vs live data represents a fundamental design decision in production AI systems. Memory includes: conversation history, user preferences, previously researched facts, and cached API responses. Live data includes: current search results, real-time prices, live inventory status, and fresh social media metrics. Getting this balance wrong causes either stale responses (over-relying on memory) or excessive costs and latency (over-fetching live data). The decision framework considers four dimensions. Freshness requirements: prices change hourly (live), company descriptions change monthly (memory OK), historical facts never change (always memory). Cost implications: live API calls cost $0.005+ each, memory retrieval is essentially free. Latency impact: memory retrieval takes milliseconds, live API calls take 200-800ms. Accuracy stakes: financial data needs live verification, general context can use memory. Production implementations typically use a tiered approach. Tier 1 (always live): prices, stock status, rankings, trending data. Tier 2 (live with 24h cache): competitor listings, review scores, business hours. Tier 3 (weekly refresh): domain authority, backlink profiles, business descriptions. Tier 4 (permanent memory): user preferences, conversation history, confirmed facts. The cache invalidation strategy is critical: time-based expiration (simplest), event-triggered refresh (price alert triggers fresh lookup), and confidence-decay (reduce trust in cached data over time, eventually triggering refresh). At $0.005/query through Scavio, the cost of unnecessary live lookups is low, so many teams default to live data for anything customer-facing and reserve memory for internal agent context.
Example Usage
The shopping agent remembers the user prefers organic products (memory) but always queries live Amazon pricing before recommending a specific product, because prices cached 6 hours ago may no longer be accurate.
