Using Spark to save rate limits?
I am using Codex CLI. I am thinking that codex uses GPT-5.3-Codex-Spark for subagents for the investigation tasks and uses 5.5 Xhigh for implementation tasks. Is this possible that 5.5 Xhigh spawns subagents with 5.3 Spark?
And are you happy with performance of 5.3 Spark's performance? For the implementation to be honest it was really bad but maybe for search capabilities are better?
