    caps = capabilities.get_capabilities(model)
    print(f"\n{model}:")
    print(f"  Context: {caps['max_context']} tokens")
    print(f"  Strengths: {', '.join(caps['strengths'])}")
    print(f"  Cost: ${caps['cost_per_1k_tokens']}/1k tokens")

# Compare models for specific task
task_requirements = {
    "type": "code_generation",
    "complexity": "high",
    "language": "python",
    "context_needed": 8000
}

best_model = capabilities.recommend_model(task_requirements)
print(f"\nBest model for task: {best_model}")

# Create agent with capability-aware model selection
smart_agent = Agent(
    name="Capability-Aware Agent",
    role="Adaptive AI Assistant",
    goal="Use the best model based on task requirements",
    instructions="Leverage model capabilities for optimal performance",
    model_selector=capabilities

# Test with different task types
coding_task = Task(
    description="Write a complex Python algorithm for graph traversal",
    expected_output="Optimized Python code with explanation",
    agent=smart_agent,
    task_type="coding"

Understanding Model Capabilities

What are Model Capabilities?

Model Capabilities system:

  • Detects and compares features across different LLMs
  • Matches task requirements with model strengths
  • Provides performance benchmarks and comparisons
  • Enables data-driven model selection
  • Tracks capability evolution over time

​
Core Features

Feature Detection

Automatically detect model capabilities and limitations.

Performance Metrics

Track speed, accuracy, and cost metrics for each model.

Capability Matching

Match task requirements with model strengths.

Comparison Tools

Compare models side-by-side for informed decisions.

Capability Detection Methods

from praisonaiagents.llm import ModelCapabilities, CapabilityTest

# Initialize capability detector
detector = ModelCapabilities()

# Run comprehensive capability tests
test_suite = CapabilityTest()

# Test reasoning capabilities
reasoning_score = test_suite.test_reasoning("gpt-4")
print(f"Reasoning score: {reasoning_score}/100")

# Test context handling
context_test = test_suite.test_context_length("claude-3-sonnet", tokens=150000)
print(f"Context handling: {'Passed' if context_test else 'Failed'}")

# Test multilingual support
languages = test_suite.test_languages("gpt-4")
print(f"Supported languages: {len(languages)}")

# Test specialized capabilities
capabilities_matrix = test_suite.run_full_test_suite([
    "gpt-4",
    "claude-3-opus",
    "gemini-pro",
    "llama-3-70b"
])

# Generate capability report
detector.generate_capability_report(capabilities_matrix, "model_comparison.html")

        "preferred": ["cost_effective", "multilingual"],
        "context": 4000
    }
}

# Match capabilities to tasks
for task_name, requirements in task_profiles.items():
    best_model = detector.match_task_to_model(requirements)
    score = detector.calculate_match_score(best_model, requirements)
    print(f"{task_name}: {best_model} (score: {score:.2f})")

​
Dynamic Capability Updates

# Monitor and update capabilities based on performance
detector.enable_performance_tracking()

# After task execution
detector.update_capability_metrics(
    model="gpt-4",
    task_type="coding",
    performance_metrics={
        "accuracy": 0.95,
        "speed": 2.3,  # seconds
        "token_efficiency": 0.85
    }
)

# Get updated recommendations based on real performance
updated_recommendation = detector.recommend_with_history(
    task_requirements,
    consider_performance=True
)

​
Capability Comparison Tools

# Generate visual capability comparison
from praisonaiagents.llm import CapabilityVisualizer

visualizer = CapabilityVisualizer()

# Create radar chart comparing models
visualizer.create_radar_chart(
    models=["gpt-4", "claude-3-opus", "gemini-pro"],
    capabilities=["reasoning", "speed", "cost", "context", "languages"],
    output="model_comparison.png"
)

# Create capability matrix heatmap
visualizer.create_heatmap(
    models=detector.list_models(),
    capabilities=detector.list_all_capabilities(),
    output="capability_matrix.png"
)

Troubleshooting

Capability Mismatches

If models aren’t performing as expected:

  • Update capability profiles
  • Run fresh benchmarks
  • Check API version changes
  • Verify task requirements

Performance Issues

If capability detection is slow:

  • Use cached results
  • Run async benchmarks
  • Limit test scope
  • Use sampling strategies
