Amp added new orb sizes and pricing with a1.medium (4 CPUs, 8 GB) at 50% cheaper than before, plus price cuts across all tiers. Orbs now auto-pause after 5 minutes of inactivity instead of 15, and startup time improved significantly. You can now choose orb size per-thread to optimize costs, using the --orb-size flag in the CLI or by instructing the agent which size to use for specific tasks.
