fix: use C8i/M8i instances for AWS nested virt (10x cheaper than metal)#124
Conversation
AWS Intel Xeon 6 families (C8i, M8i, R8i) support nested virtualization on standard (non-metal) instances since late 2025. Update default from m5.metal ($4.61/hr) to m8i.2xlarge ($0.46/hr) with fallbacks through c8i.2xlarge, r8i.2xlarge, m8i.4xlarge, and m5.metal as legacy option. Updated files: - aws_vm.py: new INSTANCE_TYPE and INSTANCE_TYPE_FALLBACKS - CLAUDE.md: updated cost table - docs/rl_quick_start.md: updated cost estimates - docs/ec2_setup_guide.md: updated instance types, costs, and instructions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
