model routing policy

primary model switching

nicholai can request any model via "switch to [alias]" (ordered by intelligence):

• opus → anthropic/claude-opus-4-5 (metered)
• glm → zai/glm-5 (free)
• sonnet → anthropic/claude-sonnet-4-5 (metered)
• kimi → opencode/openrouter/moonshotai/kimi-k2.5 (free-ish)
• gemini-flash → opencode/google/antigravity-gemini-3-flash (free)
• gemini-pro → opencode/google/antigravity-gemini-3-pro (free)

sub-agent routing

when anthropic weekly usage > 80%:

sub-agents MUST default to free models:

1. gemini-flash (preferred for lightweight tasks)
2. gemini-pro (for heavier reasoning)
3. glm-local (local fallback)

if ALL free models are unavailable:

• notify nicholai immediately
• ask: anthropic oauth or glm-local?
• do NOT auto-fall back to metered models

when anthropic weekly usage < 80%:

sub-agents can use any model as appropriate for the task

kimi fallback chain

1. kimi via ollama (preferred, local)
2. kimi via openrouter (fallback, notify nicholai)
3. if both fail: notify nicholai for alternative

checking usage

before spawning sub-agents, check usage via session_status look at weekly usage percentage to determine routing tier
