Multi-agent orchestration hype
LangGraph, CrewAI, AutoGPT cosplay — then vendor harnesses shipped the same loop as an API. Open-source swarms faded; leased orchestration stuck.
How Multi-agent orchestration hype mutated
Open-source multi-agent frameworks failed as defaults because non-determinism compounds with every hop and observability lagged behind demo videos. They mutated into first-party session APIs — OpenAI Agents, Anthropic managed agents, Bedrock AgentCore — where the swarm is a product SKU. The costly fad was autonomous headcount replacement; the stuck residue is a vendor-owned loop with MCP tools and a human somewhere in the interrupt path.
Cost of the fad
What Multi-agent orchestration hype cost
Autonomous agent swarms burned API budgets on coordination loops that a single prompt and a cron job would have handled. Debugging "which agent lied" became the new on-call sport.

LLM app frameworks
LangChain-class glue mutated into MCP clients and thin wrappers around vendor APIs. The durable pieces are still boring: evals, retrieval, and product UX.

Agent ops / LLM observability

Vibe coding
Accept AI output on feel, skip the diff, hope tests exist. Fast demos; CVEs and nobody owns the middleware.
$ Ship-to-prod without reading the diff became a flex until incidents revealed nobody knew which prompt wrote the auth middleware. Review debt arrived in one weekend demo.

LLM orchestration frameworks
Chains, tools, memory, and agents as a framework — LangChain-class glue sold as architecture. Fatigue was real; the repos became MCP clients, not tombstones.
$ Teams adopted chain/agent frameworks before they had a single reliable tool call. Abstraction layers multiplied while prompt quality stayed flat.

Vendor agent APIs

$ Teams replaced a weekend of LangGraph glue with a managed session API, then discovered residency, recovery, and kill switches all live on the vendor side of the harness.
