Dalam artikel ini, kami akan meneroka cara mencipta ejen AI untuk carian web, analisis kewangan, penaakulan dan penjanaan tambahan perolehan menggunakan phidata dan LLM tempatan Ollama. Kod menggunakan model llama3.2. Jika anda ingin menggunakan model yang berbeza, anda perlu memuat turun model yang anda mahu gunakan dan menggantikan pembolehubah model_id dalam kod.
Platform sumber terbuka untuk membina, menghantar dan memantau sistem agen.
https://www.phidata.com/
Ollama ialah platform dan set alatan yang direka untuk memudahkan penggunaan dan penggunaan model bahasa besar tempatan (LLM).
https://ollama.ai/
Dalam artikel ini, kami akan menggunakan model llama3.2.
ollama pull llama3.2
Pakej Python dan pengurus projek yang sangat pantas, ditulis dalam Rust.
https://github.com/astral-sh/uv
Jika anda tidak mahu menggunakan uv, anda boleh menggunakan pip sebagai ganti uv. Kemudian anda perlu menggunakan pemasangan pip dan bukannya uv add.
https://docs.astral.sh/uv/getting-started/installation/
Jika anda memutuskan untuk menggunakan pip, anda perlu mencipta folder projek.
uv init phidata-ollama
uv add phidata ollama duckduckgo-search yfinance pypdf lancedb tantivy sqlalchemy
Dalam artikel ini, kami akan cuba mencipta 5 ejen AI dengan phidata dan Ollama.
Nota: Sebelum bermula, pastikan pelayan ollama anda berjalan dengan menjalankan servis ollama.
Ejen pertama yang kami akan cipta ialah ejen carian web yang akan menggunakan enjin carian DuckDuckGo.
from phi.agent import Agent
from phi.model.ollama import Ollama
from phi.tools.duckduckgo import DuckDuckGo
model_id = "llama3.2"
model = Ollama(id=model_id)
web_agent = Agent(

model=model,
tools=[DuckDuckGo()],
instructions=["Always include sources"],
show_tool_calls=True,
markdown=True,
)
web_agent.print_response("Tell me about OpenAI Sora?", stream=True)
Output:
┏━ Message ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓ ┃ ┃ ┃ Tell me about OpenAI Sora? ┃ ┃ ┃ ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛ ┏━ Response (12.0s) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓ ┃ ┃ ┃ ┃ ┃ • Running: duckduckgo_news(query=OpenAI Sora) ┃ ┃ ┃ ┃ OpenAI's Sora is a video-generating model that has been trained on ┃ ┃ copyrighted content, which has raised concerns about its legality. ┃ ┃ According to TechCrunch, it appears that OpenAI trained Sora on game ┃ ┃ content, which could be a problem. Additionally, MSN reported that the ┃ ┃ model doesn't feel like the game-changer it was supposed to be. ┃ ┃ ┃ ┃ In other news, Yahoo reported that when asked to generate gymnastics ┃ ┃ videos, Sora produces horrorshow videos with whirling and morphing ┃ ┃ limbs. A lawyer told ExtremeTech that it's "overwhelmingly likely" that ┃ ┃ copyrighted materials are included in Sora's training dataset. ┃ ┃ ┃ ┃ Geeky Gadgets reviewed OpenAI's Sora, stating that while it is included ┃ ┃ in the 0/month Pro Plan, its standalone value for video generation ┃ ┃ is less clear compared to other options. ┃ ┃ ┃ ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛
Ejen kedua yang kami akan wujudkan ialah ejen kewangan yang akan menggunakan alat yfinance.
from phi.agent import Agent
from phi.model.ollama import Ollama
from phi.tools.yfinance import YFinanceTools
model_id = "llama3.2"
model = Ollama(id=model_id)

tools=[YFinanceTools(stock_price=True, analyst_recommendations=True, company_info=True, company_news=True)],
instructions=["Use tables to display data"],
show_tool_calls=True,
markdown=True,
)
finance_agent.print_response("Summarize analyst recommendations for NVDA", stream=True)
Output:
┏━ Message ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓ ┃ ┃ ┃ Summarize analyst recommendations for NVDA ┃ ┃ ┃ ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛ ┏━ Response (3.9s) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓ ┃ ┃ ┃ ┃ ┃ • Running: get_analyst_recommendations(symbol=NVDA) ┃ ┃ ┃ ┃ Based on the analyst recommendations, here is a summary: ┃ ┃ ┃ ┃ • The overall sentiment is bullish, with 12 strong buy and buy ┃ ┃ recommendations. ┃ ┃ • There are no strong sell or sell recommendations. ┃ ┃ • The average price target for NVDA is around 0-0. ┃ ┃ • Analysts expect NVDA to continue its growth trajectory, driven by ┃ ┃ its strong products and services in the tech industry. ┃ ┃ ┃ ┃ Please note that these recommendations are subject to change and may ┃ ┃ not reflect the current market situation. It's always a good idea to do ┃ ┃ your own research and consult with a financial advisor before making ┃ ┃ any investment decisions. ┃ ┃ ┃ ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛
Ejen ketiga yang akan kami wujudkan ialah pasukan ejen yang akan menggunakan enjin carian DuckDuckGo dan alatan YFinance.

show_tool_calls=True,
markdown=True,

agent_team.print_response("Summarize analyst recommendations and share the latest news for NVDA", stream=True)
Ejen keempat yang akan kami cipta ialah ejen inferens yang akan menggunakan tugas.
from phi.agent import Agent from phi.model.ollama import Ollama model_id = "llama3.2" model = Ollama(id=model_id) task = ( "Three missionaries and three cannibals want to cross a river." "There is a boat that can carry up to two people, but if the number of cannibals exceeds the number of missionaries, the missionaries will be eaten." ) reasoning_agent = Agent(model=model, reasoning=True, markdown=True, structured_outputs=True) reasoning_agent.print_response(task, stream=True, show_full_reasoning=True)
Output:
