Model Types#

When initializing an agent, you need to specify which model to use. The model type can be provided as a parameter when creating either OpenAIBase or AnthropicBase agents, using the respective enums OpenAIModelType and AnthropicModelType.

OpenAI Models#

For OpenAIBase agents, you can use any of these OpenAIModelType values:

  • gpt3_5 - "gpt-3.5-turbo-0125"
  • gpt3_5_turbo - "gpt-3.5-turbo"
  • gpt4 - "gpt-4"
  • gpt4_turbo - "gpt-4-turbo"
  • gpt4o_mini - "gpt-4o-mini" (128,000 tokens)
  • gpt4o - "gpt-4o"
  • gpt_o1_mini - "o1-mini"
  • gpt_o1_preview - "o1-preview"

Anthropic Models#

For AnthropicBase agents, you can use any of these AnthropicModelType values:

  • claude_3_5_sonnet - "claude-3-5-sonnet-20240620"
  • claude_3_opus - "claude-3-opus-20240229"
  • claude_3_sonnet - "claude-3-sonnet-20240229"
  • claude_3_haiku - "claude-3-haiku-20240307"
  • claude_2_1 - "claude-2.1"
  • claude_2_0 - "claude-2.0"
  • claude_instant_1_2 - "claude-instant-1.2"

Then, when you create an agent, you can specify the model type as a parameter:

from emp_agents import AgentBase
from emp_agents.providers import OpenAIProvider, OpenAIModelType, AnthropicProvider, AnthropicModelType

# for openai models
agent = AgentBase(
    provider=OpenAIProvider(),
    default_model=OpenAIModelType.gpt4o_mini
)

# or for anthropic
agent = AgentBase(
    provider=AnthropicProvider(),
    default_model=AnthropicModelType.claude_3_5_sonnet
)
