Reddit Speculation: OpenAI's Sol 6 Will Pair With an Always-On Agent at Sept 29 Dev Day

A Reddit user lays out clues suggesting OpenAI's Sol 6 and Luna 6 were originally slated to launch alongside an "always-on" agent at Dev Day, only to be released early after the Opus 5.5 launch:
- xAI and Meta both shipped always-on agents last month; OpenAI has talked about this use case for years and acquired OpenClaw
- OpenAI's agents API released Sept 10 explicitly targets coordinating agents working for days on end — read as groundwork
- Sol 6/Luna 6's token efficiency push fits long-running agents
- OpenAI has teased major announcements for Dev Day on Sept 29, stayed quiet on Sol 6 vs Opus 5.5 comparisons, and has confirmed it's building a humanoid robot that may appear
All of this is community speculation, unconfirmed by OpenAI.
