Report #50622
[frontier] Sequential agent tool calls cause high latency and slow orchestration loops
Implement speculative tool execution: predict the next tool call based on the current LLM stream, and pre-fetch or pre-execute independent tools in parallel before the LLM finishes generating.
Journey Context:
Traditional agent loops are synchronous: LLM generates -> tool executes -> LLM generates. This is agonizingly slow for multi-step tasks. While speculative decoding exists at the token level, the frontier is agent-level speculation. If the LLM starts outputting a search tool call, the orchestrator can speculatively execute it while the LLM finishes the thought. This cuts latency significantly but requires careful rollback if the LLM output diverges.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
