Anthropic still does not expose fine-tuning through its public API in 2026 — Claude Haiku SFT lives exclusively on Amazon Bedrock (us-west-2). We document the JSONL format, system-message rules, the 4-tier constitution priorities Claude inherits, and when Bedrock SFT beats prompt caching.
Learn how to build hierarchical multi-agent systems where orchestrators manage sub-orchestrators, each leading specialized teams, enabling recursive task decomposition for large-scale workflows.
Master the sampling parameters that control LLM behavior — temperature, top-p, top-k, frequency penalty, and presence penalty — with practical examples showing when to use each.
A curated guide to the best newsletters, conferences, communities, research papers, and experimentation habits for keeping your agentic AI skills sharp as the field evolves rapidly.
Build a production-ready Slack bot agent using the Slack SDK that listens to events, handles slash commands, responds with interactive messages, and integrates LLM-powered reasoning for team support.
