Is it possible to set a specific conversation to use a given model? E.g. I want conversation 1 to use Claude Opus while conversation 2 uses gemini 3 high and conversation 3 uses gemini flash?
And somewhat related, is it possible to have antigravity automatically spin up sub agents for dividing code work (e.g. a complex implementation plan with multiple phases)?
Hello @Scott_Casey, welcome to AI Forum!
The ability to have “Conversation A” locked to one model and “Conversation B” locked to another is a highly requested feature (often called “Model Sticky-ness”), but it is not a standard feature in the current Antigravity interface.
Antigravity is architected as an agent-first platform, meaning the Agent Manager (Mission Control) automatically delegates specific tasks to specialized Sub-agents to optimize performance and context usage. For example, when a task requires web research or documentation lookup, the system invokes the Browser Subagent; for command-line operations, it uses the Terminal Subagent. This allows the main model (e.g., Gemini 3 Pro) to focus on high-level reasoning while specialized models handle the execution details in parallel.
The ability to architect custom sub-agents with specialized skills—essentially treating them as programmable AI modules is not available in Antigravity at this time.
