Kimi K3 and the Agentic Frontier

About this book

Kimi K3 and the Agentic Frontier examines modern agentic AI by separating the model, harness, agent, product, and infrastructure layers that are often conflated. The book studies long context versus memory and compaction, sparse mixture-of-experts design, native vision, open weights, serving and self-hosting, agent swarms, sandboxed execution, economics, failure modes, benchmarks, and product-level comparisons with Claude, ChatGPT Work, and Codex. Time-sensitive specifications and vendor claims are treated as dated evidence rather than timeless facts.

What you will learn

• Distinguish a foundation model from its harness, agent layer, product surface, and infrastructure.
• Evaluate long-context claims separately from memory, retrieval, and compaction strategies.
• Understand open-weight deployment, serving constraints, and swarm economics.
• Compare agent products through controlled tasks, latency, cost, and human-attention requirements.
• Read vendor specifications and benchmark claims with explicit dates, evidence, and limitations.
