Overview
Switch models per-call without recreating the agent. Useful for cost optimization or capability matching.
Quick Start
from praisonaiagents import Agent
agent = Agent(
name="FlexBot",
instructions="Helper",
llm={"model": "gpt-4o-mini", "configurable": True}
)
# Default model
response = agent.chat("Hello")
# Override model per-call
response = agent.chat("Complex task", config={"model": "gpt-4o"})
# Override temperature
response = agent.chat("Creative task", config={"temperature": 0.9})
Config Options
| Key | Description |
|---|
model | Override model name |
temperature | Override temperature |
provider | Override provider (openai, anthropic) |
Permanent Model Switching
Use switch_model() to permanently change the agent’s model while preserving conversation history:
from praisonaiagents import Agent
agent = Agent(
name="FlexBot",
instructions="Helper",
llm="gpt-4o-mini"
)
# Chat with initial model
agent.chat("Hello")
# Permanently switch to a different model
agent.switch_model("gpt-4o")
# All subsequent calls use the new model
agent.chat("Complex task") # Uses gpt-4o
# Conversation history is preserved
print(len(agent._chat_history)) # Shows previous messages
Thread Safety
Config overrides are per-call and do not mutate agent defaults. Safe for concurrent use.
