r/AI_Agents: Developer Routes 24/7 Autonomous Agent Dev Org Across Claude, Kimi, MiniMax, and GPT by Role to Dodge ~$2K/Month Claude Max Overrun

A developer running a 24/7 autonomous engineering org of AI agents documents hitting Claude Max's weekly usage cap by mid-week, then pricing raw API access for the same workload at $2K+/month. Their solution: route each agent role — orchestrator, coder, reviewer, tester — to different models by cost-capability fit, mixing Claude for complex reasoning, Kimi and MiniMax for mid-tier tasks, and GPT for specific integrations. The post details which roles silently degrade at which models, which failure modes only appear at scale and runtime (context boundary mismatches, provider-specific rate-limit behaviors, inconsistent tool-call schemas), and the minimal tooling changes needed to manage multi-provider agent state in production.
