Instance Method Details

#insert(position, model) ⇒ Object

Insert a single model entry at an arbitrary position in the final chain. Position 0 is the same as prepend; -1 appends after the last element.

agent.models.insert(0,  { provider: :openrouter, model: "fast-model" })
agent.models.insert(2,  { provider: :openrouter, model: "mid-model" })
agent.models.insert(-1, { provider: :openrouter, model: "last-resort" })
