Summary
DeepSeek TUI PR #3812 allows multiple agent starts to join parallel dispatch batches. The fix reduces launch serialization that hurt high-fanout multi-agent workflows.
What changed
DeepSeek TUI changed agent start handling so multiple agent tool calls in a parent turn can be dispatched in parallel rather than launched serially.
Why it matters
Multi-agent systems only feel useful when fanout does not create linear waiting time. This update directly targets orchestration latency for users launching many subagents at once.
