Voice bot team: GPT Live 1 and Gemini 3.8 Thinking both fail in production

Mr_Nice_ · reddit · 2026-10-23

A developer building voice bots shares production findings: GPT Live 1 delegates inconsistently — fine in simple demos, but derails in long conversations with prior delegations, and ending calls requires odd workarounds. Gemini 3.8 Extended Thinking works better but is slow and leaves dead air during long thinking pauses.

Their in-house two-agent system (a blocking tool call to a thinking endpoint, with a second agent feeding progress back as system messages) outperforms both official releases. They ask who else runs these models for complex production voice agents.
