Agent Frameworks Behind the Gateway
LangGraph, CrewAI, AutoGen pointed at a single base URL — the gateway gives the agent loop optionality, fallback, and cost governance the frameworks themselves do not provide.
💡
Tip: Agent frameworks are great at orchestration and weak at platform concerns. The gateway fills the gap.
What this use case covers
-
LangGraph, CrewAI, and AutoGen all configured against the same
OPENAI_BASE_URL— the gateway. - What the gateway gives the agent loop that the framework does not: fallback, cost governance, per-key budgets, observability, and audit.
- A working agent that uses three providers through the gateway without per-provider code.
- The cost-blow-up failure mode specific to agents (loops, retries, tool-call cascades) and how budgets cap it.
