AutoGPT-class autonomous agents
Give the model a goal and a credit card. Viral in 2023; quietly shelved when the loop never stopped spending.
Why AutoGPT-class autonomous agents became a costly fad
AutoGPT-class agents failed because open-ended autonomy without evals, budgets, or tool reliability produces expensive wanderlust. Narrow copilots stuck; fully autonomous rewrite/ops agents did not. The fad sold headcount replacement; the residue is constrained tool-use with a human in the loop.
Cost of the fad
What AutoGPT-class autonomous agents cost
Open-ended agent loops burned API credits chasing goals nobody specified well enough to finish. Demo videos outpaced production deployments by orders of magnitude.

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.
$ 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.

AI will rewrite the codebase
Big-bang rewrite, now with a chatbot — then with agents. Same failure mode; prettier slides.
$ Exec decks promised autonomous migrations "by next quarter," then rebranded as "agentic modernization." Teams that skipped tests, ownership, and incremental strangler patterns bought expensive demos and fragile diffs.

Agent ops / LLM observability
Tracing, cost caps, and prompt versioning for production LLM features — mostly constrained tool loops, not autonomous agents. Datadog for tokens.

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.
