Implementation Guide

Model Initialization

from langchain_ollama import ChatOllama 

# Initialize model instance
llm = ChatOllama(model="<model_name>")

Basic Usage Example

# Arithmetic computation example
query = "What is 3 * 12? Also, what is 11 + 49?"
response = llm.invoke(query)

print(response.content)
# Output:
# 1. 3 times 12 is 36.
# 2. 11 plus 49 is 60.

Advanced Function Calling (English Recommended)

Basic Arithmetic Tools (Different from the first version)

from pydantic import BaseModel

# Note that the docstrings here are crucial, as they will be passed along
# to the model along with the class name.
class add(BaseModel):
    """Add two integers together."""

    a: int = Field(..., description="First integer")
    b: int = Field(..., description="Second integer")

class multiply(BaseModel):
    """Multiply two integers together."""

    a: int = Field(..., description="First integer")
    b: int = Field(..., description="Second integer")

tools = [add, multiply]
llm_with_tools = llm.bind_tools(tools)

# Execute query and parser result (Different from the first version)
from langchain_core.output_parsers.openai_tools import PydanticToolsParser

query = "What is 3 * 12? Also, what is 11 + 49?"
chain = llm_with_tools | PydanticToolsParser(tools=tools)
result = chain.invoke(query)
print(result)

# Output:
# [multiply(a=3, b=12), add(a=11, b=49)]

Complex Tool Integration (Different from the first version)

from pydantic import BaseModel, Field
from typing import List, Optional

class SendEmail(BaseModel):
    """Send an email to specified recipients."""

    to: List[str] = Field(..., description="List of email recipients")
    subject: str = Field(..., description="Email subject")
    body: str = Field(..., description="Email content/body")
    cc: Optional[List[str]] = Field(None, description="CC recipients")
    attachments: Optional[List[str]] = Field(None, description="List of attachment file paths")

class WeatherInfo(BaseModel):
    """Get weather information for a specific location."""

    city: str = Field(..., description="City name")
    country: Optional[str] = Field(None, description="Country name")
    units: str = Field("celsius", description="Temperature units (celsius/fahrenheit)")

class SearchWeb(BaseModel):
    """Search the web for given query."""

    query: str = Field(..., description="Search query")
    num_results: int = Field(5, description="Number of results to return")
    language: str = Field("en", description="Search language")

class CreateCalendarEvent(BaseModel):
    """Create a calendar event."""

    title: str = Field(..., description="Event title")
    start_time: str = Field(..., description="Event start time (ISO format)")
    end_time: str = Field(..., description="Event end time (ISO format)")
    description: Optional[str] = Field(None, description="Event description")
    attendees: Optional[List[str]] = Field(None, description="List of attendee emails")

class TranslateText(BaseModel):
    """Translate text between languages."""

    text: str = Field(..., description="Text to translate")
    source_lang: str = Field(..., description="Source language code (e.g., 'en', 'es')")
    target_lang: str = Field(..., description="Target language code (e.g., 'fr', 'de')")

class SetReminder(BaseModel):
    """Set a reminder for a specific time."""

    message: str = Field(..., description="Reminder message")
    time: str = Field(..., description="Reminder time (ISO format)")
    priority: str = Field("normal", description="Priority level (low/normal/high)")
tools = [
    SendEmail,
    WeatherInfo,
    SearchWeb,
    CreateCalendarEvent,
    TranslateText,
    SetReminder
]
llm_tools = llm.bind_tools(tools)

# # Execute query and parser result (Different from the first version)
from langchain_core.output_parsers.openai_tools import PydanticToolsParser

query = "Set a reminder to call John at 3 PM tomorrow. Also, translate 'Hello, how are you?' to Spanish."
chain = llm_tools | PydanticToolsParser(tools=tools)
result = chain.invoke(query)
print(result)

# Output:
# [SetReminder(message='Set a reminder for a specific time.', time='3 PM tomorrow', priority='normal'),
# TranslateText(text='Hello, how are you?', source_lang='en', target_lang='es')]

Known Limitations

• Basic function/tool calling
• English language support exclusively
• Ollama installation dependency

Important Notes & Considerations

Potential Limitations and Edge Cases

• Function Parameter Sensitivity: The model may occasionally misinterpret complex parameter combinations, especially when multiple optional parameters are involved. Double-check parameter values in critical applications.

• Response Format Variations:

  • In some cases, the function calling format might deviate from the expected JSON structure
  • The model may generate additional explanatory text alongside the function call
  • Multiple function calls in a single query might not always be processed in the expected order

• Error Handling Considerations:

  • Empty or null values might not be handled consistently across different function types
  • Complex nested objects may sometimes be flattened unexpectedly
  • Array inputs might occasionally be processed as single values

Best Practices for Reliability

1. Input Validation:

   • Always validate input parameters before processing
   • Implement proper error handling for malformed function calls
   • Consider adding default values for optional parameters

2. Testing Recommendations:

   • Test with various input combinations and edge cases
   • Implement retry logic for inconsistent responses
   • Log and monitor function call patterns for debugging

3. Performance Optimization:

   • Keep function descriptions concise and clear
   • Limit the number of simultaneous function calls
   • Cache frequently used function results when possible

Known Issues

• Model may struggle with:
  • Very long function descriptions
  • Highly complex nested parameter structures
  • Ambiguous or overlapping function purposes
  • Non-English parameter values or descriptions
