Reasoning Finance Agent

Prepare a financial report with a separate DeepSeek reasoning stage and finance tools.

Demonstrates DeepSeek-backed reasoning with tools for financial reporting.

DeepSeek retired the deepseek-reasoner alias after July 24, 2026. Before running this archived example, replace DeepSeek(id="deepseek-reasoner") with DeepSeek(id="deepseek-v4-flash") in the saved program. The main OpenAI model remains a separate call, so both provider keys are required. See the DeepSeek V4 migration notice.

        "Write a report comparing NVDA to TSLA",
        stream=True,
        show_full_reasoning=True,
    )

An explicit reasoning_model runs as a separate, tool-free reasoning stage before the main model response. show_full_reasoning=True displays the reasoning data Agno receives; it cannot reveal a provider's private internal trace. Some adapters use the reasoning stage's answer text when separate reasoning content is unavailable. A failed reasoning stage can still be followed by a main-model answer, so a completed run alone does not prove the reasoning stage succeeded.

Run the Example

Set up your virtual environment

uv venv --python 3.12
source .venv/bin/activate

Install dependencies

uv pip install -U agno openai yfinance

Export your API keys

export DEEPSEEK_API_KEY="your_deepseek_api_key_here"
export OPENAI_API_KEY="your_openai_api_key_here"

Run the example

Save the code above as finance_agent.py, then run:

python finance_agent.py
