🤖💬📈🌍 Build a Real-Time AI Sales Agent - Sarah Chieng & Zhenwei Gao, Cerebras

🤖 AI Summary

🚀 Cerebras hardware eliminates memory bandwidth bottlenecks by placing SRAM directly on each of its 900,000 cores [06:18].
⚡ Inference speeds reach 20x to 70x faster than traditional GPUs due to this wafer-scale integration [04:50].
🧠 Speculative decoding uses a small draft model for speed and a large model for verification to optimize performance [07:27].
🗣️ Voice agents function as stateful systems that simultaneously listen, think, and respond using WebRTC for low latency [09:06].
🛠️ Real-time orchestration requires Speech-to-Text (STT), Large Language Models (LLMs), and Text-to-Speech (TTS) engines [10:42].
🛑 Voice Activity Detection (VAD) coupled with turn-detection models prevents awkward interruptions during natural speech [11:03].
📚 Context loading via structured data reduces hallucinations by providing specific product details and objection handlers [16:32].
🔄 Multi-agent architectures improve accuracy by routing queries to specialized agents like technical or pricing experts [21:08].
🔗 Handover mechanisms allow a greeting agent to identify intent and transfer the session to the relevant specialist [22:22].

⚖️ While Cerebras claims massive speed advantages, NVIDIA maintains a dominant ecosystem with CUDA, which remains the industry standard for software compatibility according to The State of AI Report by Air Street Capital.
🌐 The focus on on-chip memory is a distinct architectural choice compared to the HBM-heavy approach of NVIDIA H100s, which prioritize massive parallel throughput for training over ultra-low latency inference.
🔍 Research into multi-agent systems by Microsoft (AutoGen) suggests that while routing improves specialization, it can increase orchestration complexity and error rates in handoffs.

🤖 A: It uses a wafer-scale engine that integrates memory directly onto the processing cores to eliminate off-chip data transfer delays [06:35].

🤖 A: HTTP is designed for text and has high overhead, whereas WebRTC enables sub-100ms latency for real-time voice data transmission [15:24].

🤖 A: It allows for specialized knowledge silos, ensuring technical or pricing questions are handled by models with specific relevant context [21:42].
