Ben Zanghi
Head of Technology at Relevate Health, where I lead AI strategy and platform engineering for omnichannel HCP engagement across pharma. Building production AI systems and publishing findings on conversational AI, memory architecture, and agent orchestration.
What I'm Building
PersonaPlex-MLX: On-Device Speech AI
Porting Kyutai's Mimi neural codec to Apple Silicon via MLX. Runs entirely on-device with native Metal GPU acceleration — no cloud, no latency.
Relevate Health: AI-Driven HCP Engagement
Leading technology strategy for an omnichannel healthcare marketing platform. Building AI-powered workflows for HCP targeting, content personalization, and campaign measurement across pharma clients.
Nine Tendencies: Personality Assessment
AI-powered personality framework based on cognitive and behavioral patterns. V2 in development with enhanced assessment algorithms.
Engram: Cognitive AI Memory
Memory system for conversational AI based on cognitive science principles (consolidation, decay, reconsolidation). 3,030 memories, 87.9% entity coverage.
AgentEvolve: AI Orchestration Research
Evolutionary search over AI agent patterns. Found that direct prompting beats multi-step workflows at 30B scale. 12 candidates × 10 generations × 5 benchmarks.
Project Prometheus: AI Evolution
Interactive educational simulation visualizing AI capability progression from rule-based systems to transformers. Interactive timeline and model comparisons.
Claudia Voice: Conversational AI
Two-tier voice assistant with local GLM routing and Claude deep path. 85% simple queries handled at 700ms latency. Smart home + semantic memory.
Past Work
WonderWeave
AI-powered personalized children's stories with voice cloning. Live product demonstrating generative AI for creative applications.
GroceryZ: Smart Shopping
AI grocery shopping assistant with smart lists, price tracking, and personalized recommendations. Influenced NineTendencies architecture.
arXiv Research Hub
Personal AI paper monitoring with automated summarization and relevance scoring. Direct precursor to Engram memory patterns.
Video Work
Selected video projects spanning healthcare marketing, brand storytelling, and AI product demos. Includes a depression awareness concept commercial and the WonderWeave sizzle reel.
Publications
Engram: Cognitive-Inspired AI Memory Architecture
Building a production memory system for conversational AI based on cognitive science principles. Dual storage, temporal validity, uncertainty tracking, and entity deduplication in production.
AgentEvolve: When LLM Orchestration Helps — and When It Hurts
Evolutionary search over AI agent orchestration patterns. 18 experiments across 6 models (7B–405B parameters) reveal that orchestration effectiveness depends entirely on model scale.
Claudia Voice: Two-Tier Conversational AI Architecture
Building a production voice assistant with local GLM routing and semantic memory. 85% of queries handled at 700ms latency with smart home integration and Engram memory.
PersonaPlex-MLX: Porting a Neural Codec to Apple Silicon
Porting Kyutai's Mimi neural audio codec to Apple Silicon using MLX. On-device speech encoding and decoding with no cloud dependency, running at native Metal GPU speeds.
