——0——
Claude Code added a fast mode research preview for Opus 4.7 alongside support for up to five simultaneous teammate agents. The mode is priced at $30 per million input tokens and $150 per million output tokens. Agent teams require version 2.1.32 or later and use a lead agent that splits work across teammates, each handling five to six tasks. Users including Dan Siroker documented the parallel sessions.
