Authentication

export ANTHROPIC_API_KEY="sk-ant-..."

Examples

from upsonic import Agent, Task
from upsonic.models.anthropic import AnthropicModel

model = AnthropicModel(model_name="claude-3-5-sonnet-20241022")
agent = Agent(model=model)

task = Task("Hello, how are you?")
result = agent.do(task)
print(result)

Model Settings

You can set model parameters in two ways: on the model or on the Agent. On the model:

from upsonic import Agent, Task
from upsonic.models.anthropic import AnthropicModel, AnthropicModelSettings

model = AnthropicModel(
    model_name="claude-sonnet-4-5",
    settings=AnthropicModelSettings(max_tokens=2048, temperature=0.5)
)
agent = Agent(model=model)

On the Agent:

from upsonic import Agent, Task
from upsonic.models.anthropic import AnthropicModelSettings

agent = Agent(
    model="anthropic/claude-sonnet-4-5",
    settings=AnthropicModelSettings(max_tokens=2048, temperature=0.5)
)
