Creating Models

Models are defined as Pydantic classes that inherit from FortitudeBaseModel:

from fortitude.backend.models import FortitudeBaseModel
from pydantic import Field
from typing import Optional

class User(FortitudeBaseModel):
    name: str
    email: str
    age: Optional[int] = None

Register the model in your main application:

from backend.models.user import User
app.register_model(User)

Advanced Rails-like Scaffolding

# Generate an MCP client for a model
fort model-mcp-client User --endpoint http://localhost:8888/mcp

# Generate an MCP server for a model
fort model-mcp-server User --port 8889

Agent Training

Fortitude includes a comprehensive system for collecting, processing, and leveraging agent training data:

Collecting Training Data

from fortitude.core import FortitudeApp

app = FortitudeApp("MyApplication")

# Record an agent interaction
interaction = await app.record_agent_interaction(
    human_input="What is the status of my order?",
    context_info={"domain": "customer_service", "user_id": "user123"}
)

# Create a training corpus
corpus = await app.create_training_corpus(
    name="Customer Service Interactions",
    description="Interactions related to order status inquiries",
    tags=["customer_service", "orders", "status"]
)

# Generate a training dataset from corpora
dataset = await app.generate_training_dataset(
    corpus_ids=["corpus_id_1", "corpus_id_2"],
    name="Order Status Dataset",
    description="Training data for handling order status inquiries"
)

Neural-Powered Data Processing

# Analyze text with neural models
analysis = await app.analyze_text(
    text="Show me the status of order #12345",
    analysis_types=["intent", "complexity", "entities"]
)

# Find similar examples using vector similarity search
similar_examples = await app.find_similar_examples(
    query="What's happening with my recent purchase?",
    top_k=5
)

# Enhance dataset with neural data augmentation
enhanced_dataset = await app.enhance_dataset(
    dataset_id="dataset_id_1",
    enhancement_types=["paraphrase", "counterfactual", "difficulty_adjustment"]
)

# Run benchmark evaluation on a dataset
benchmark_results = await app.run_benchmark(
    dataset_id="dataset_id_1",
    benchmark_id="standard_qa_benchmark"
)

Advanced Neural Training Environment

# Register a fine-tuned model
model_info = await app.register_model(
    model_id="order_status_specialist_v1",
    model_info={
        "type": "fine_tuned",
        "base_model": "claude-3-opus",
        "training_dataset": "dataset_id_1",
        "parameters": {
            "epochs": 3,
            "learning_rate": 5e-5,
            "batch_size": 32
        }
    }
)

# Create a simulation environment for testing agents
simulation_env = await app.create_simulation(
    env_id="order_workflow_simulation",
    config={
        "scenarios": [
            "new_order", "order_tracking", "order_issue", "order_cancellation"
        ],
        "tools": [
            "order_database", "shipping_tracker", "payment_processor"
        ],
        "difficulty_levels": ["easy", "medium", "hard", "expert"],
        "evaluation_metrics": ["success_rate", "efficiency", "user_satisfaction"]
    }
)

Sampling from LLMs

# Sample from LLM using MCP
result = await endpoint.sample_llm(
    prompt="What insights can you provide about this data?",
    system_prompt="You are a data analysis expert",
    max_tokens=1000
)

The client will display the sample request and handle user approval through the MCP protocol.

Accessing the UI

Once the servers are running:

• UI Server: http://localhost:9996
• API Server: http://localhost:9997
• API Documentation: http://localhost:9997/docs
• MCP Server: http://localhost:8888/mcp (when running)

Advanced Agent Training and Finetuning

Fortitude provides a comprehensive framework for agent training data collection, processing, and model finetuning:

# Start MCP server with training data collection enabled
from fortitude.backend.mcp import MCPServer
from fortitude.core import AgentTrainingManager, TrainingCurriculum

# Initialize server with training collection
server = MCPServer(name="My MCP Server", collect_training_data=True)

# Register tools that will be tracked in the training data
async def calculator(params):
    x = params.get("x", 0)
    y = params.get("y", 0)
    op = params.get("operation", "add")
    
    if op == "add":
        return x + y
    elif op == "subtract":
        return x - y
    # etc.

server.register_tool_handler("calculator", calculator)

# Later, export and process the collected training data with advanced features
training_manager = AgentTrainingManager()

# Register a domain-specific handler for financial tasks
async def finance_domain_handler(sequence, interaction):
    # Enhance financial training examples with special annotations
    sequence.annotations["financial_entities"] = {"amounts": [...], "accounts": [...]}
    return sequence

training_manager.domain_specific_handlers["finance"] = finance_domain_handler

# Create a quality filter
def quality_filter(sequence):
    # Only include high-quality examples with multiple actions
    return (sequence.quality_score is None or sequence.quality_score > 0.7) and len(sequence.actions) > 1

training_manager.quality_filters["high_quality_multi_step"] = quality_filter

# Generate an advanced dataset with curriculum
dataset = await training_manager.create_training_dataset(
    corpus_ids=["default"],
    name="Agent Sequential Actions Dataset",
    description="Training data for sequential tool usage",
    create_curriculum=True,
    generate_supervised_examples=True
)

# Export in various formats
await training_manager.export_dataset(
    dataset.dataset_id, 
    output_path="agent_training_data.jsonl"
)

Advanced Capabilities

The training data system incorporates numerous advanced features:

1. Structured Data Capture

• Complete interaction sessions with context preservation
• Detailed tool usage tracking with parameters and results
• Performance and resource usage metrics

2. Intelligent Processing

Fortitude vs MCP Python SDK

Fortitude offers a streamlined yet more powerful approach to building MCP-enabled applications compared to the standard MCP Python SDK.

Core Concepts: Unmatched Simplicity with Power

Server Definition

MCP Python SDK:

from mcp.server.fastmcp import FastMCP

mcp = FastMCP("Demo")

Fortitude Framework:

from fortitude.backend.mcp import FortitudeMCP

# More capabilities, similar simplicity
mcp = FortitudeMCP("Demo", 
                   auto_discovery=True,  # Automatically find models
                   caching=True)         # Intelligent result caching

Lifespan Management

MCP Python SDK:

@asynccontextmanager
async def app_lifespan(server: FastMCP) -> AsyncIterator[AppContext]:
    db = await Database.connect()
    try:
        yield AppContext(db=db)
    finally:
        await db.disconnect()

mcp = FastMCP("My App", lifespan=app_lifespan)

Fortitude Framework:

from fortitude.backend.mcp import FortitudeMCP, lifecycle

# Declarative lifecycle with automatic dependency resolution
@lifecycle.database("postgres")
@lifecycle.redis("cache")
@lifecycle.secure_vault("secrets")
class AppContext:
    pass

mcp = FortitudeMCP("My App", context=AppContext)

Resources

MCP Python SDK:

@mcp.resource("users://{user_id}/profile")
def get_user_profile(user_id: str) -> str:
    """Dynamic user data"""
    return f"Profile data for user {user_id}"

Fortitude Framework:

from fortitude.backend.models import FortitudeBaseModel
from typing import Optional, List

# Define once, use everywhere - model-driven resources
class UserProfile(FortitudeBaseModel):
    user_id: str
    name: str
    email: str
    preferences: dict

# Automatic REST + MCP resource generation
@mcp.model_resource()
async def get_user_profile(user_id: str) -> UserProfile:
    """Fully typed resource with automatic validation"""
    return await UserProfile.get(user_id)

Tools

MCP Python SDK:

@mcp.tool()
def calculate_bmi(weight_kg: float, height_m: float) -> float:
    """Calculate BMI given weight in kg and height in meters"""
    return weight_kg / (height_m**2)

Fortitude Framework:

from fortitude.backend.models import FortitudeToolModel
from pydantic import Field, validator

# Declarative tool definition with built-in validation
class BMICalculator(FortitudeToolModel):
    """Calculate BMI with complete validation and documentation"""
    weight_kg: float = Field(..., gt=0, description="Weight in kilograms")
    height_m: float = Field(..., gt=0, description="Height in meters")
    
    @validator("height_m")
    def height_reasonable(cls, v):
        if v > 3.0:
            raise ValueError("Height seems unreasonably tall")
        return v
    
    def calculate(self) -> float:
        """Returns Body Mass Index"""
        return self.weight_kg / (self.height_m**2)

# Automatic registration and exposure
mcp.register_tool(BMICalculator)

Multi-Modal Support

MCP Python SDK:

@mcp.tool()
def create_thumbnail(image_path: str) -> Image:
    """Create a thumbnail from an image"""
    img = PILImage.open(image_path)
    img.thumbnail((100, 100))
    return Image(data=img.tobytes(), format="png")

Fortitude Framework:

from fortitude.core.visualization import ImageProcessor
from fortitude.backend.models import FortitudeBaseModel
from pydantic import Field

# Rich declarative image processing with validation
class Thumbnail(FortitudeBaseModel):
    image_path: str
    width: int = Field(100, description="Thumbnail width in pixels")
    height: int = Field(100, description="Thumbnail height in pixels")
    format: str = Field("png", description="Output format")
    
    # Automatically handles format conversion, optimization, and caching
    @property
    def processed_image(self):
        return ImageProcessor.resize(
            self.image_path, 
            (self.width, self.height),
            format=self.format,
            progressive=True
        )

@mcp.model_tool()
async def create_thumbnail(params: Thumbnail) -> bytes:
    """Fully validated image processing with optimal formats"""
    return await params.processed_image

Advanced Capabilities Beyond Traditional MCP

Fortitude's distributed architecture delivers capabilities far beyond standard MCP implementations:

1. Quantum-Inspired Mesh Networking

• Self-organizing topology adapts like neural networks for optimal signal propagation
• Small-world network principles ensure any node can reach any other in O(log n) hops
• Dual synchronous/asynchronous communication allows both immediate responses and background processing

2. Byzantine Fault Tolerance

• Vector-clock consensus ensures consistent ordering across distributed events
• Zero-trust verification of all messages with cryptographic attestation
• Byzantine fault tolerance operates correctly even with up to 1/3 of nodes compromised

3. Multi-modal Resource Management

• Federated compute clusters dynamically form around data-intensive tasks
• Automatic resource discovery and classification creates a unified compute fabric
• Gradient-based distribution of ML workloads with automatic parameter synchronization

4. Adaptive Resilience

• Self-healing connections automatically reroute around failed or slow nodes
• Circuit breakers prevent cascade failures with intelligent backpressure
• Predictive recovery simulates failure modes and prepares recovery strategies

5. Intelligent Message Routing

• Content-based routing directs messages based on payload contents and schema
• Automatic payload compression with adaptive algorithms based on content type
• Priority-weighted queuing ensures critical messages are processed first

6. Security and Compliance

• Homomorphic encryption allows computation on encrypted data for privacy-preserving analytics
• Fine-grained permissions at the field level with role and attribute-based access control
• Cryptographic audit trails provide tamper-proof evidence of all operations

7. Distributed Observability

• Causality-preserving traces follow operations across the entire mesh
• Automatic bottleneck detection with self-tuning performance optimization
• Anomaly detection identifies unusual patterns before they become problems

Fortitude's distributed architecture combines cutting-edge research in distributed systems, cryptography, and machine learning to create a self-organizing nervous system for intelligent applications—without requiring DevOps specialists to configure and maintain complex infrastructure.

This implementation establishes a new paradigm for API development through a neural-adaptive approach that transcends traditional frameworks with unprecedented context awareness, evolutionary intelligence, and frictionless collaboration.

Revolutionary API Development Paradigm

Neural-Cognitive Architecture

• Self-Evolving Knowledge Graph: Continuously builds and refines a knowledge representation of the entire API ecosystem
• Multi-Agent Collaboration Engine: Specialized neural systems work in concert on different aspects of API design
• Contextual Understanding: Comprehends design intent beyond specifications, capturing business goals and architectural vision
• Decision Confidence Quantification: Provides certainty metrics with all recommendations, highlighting areas needing human judgment

Enterprise-Grade Architectural Intelligence

• Cross-System Pattern Recognition: Identifies patterns and anti-patterns across the entire architectural landscape
• Architectural Impact Analysis: Predicts how changes will ripple through connected systems
• Automatic Reference Architecture Alignment: Ensures all APIs conform to organizational standards
• Technical Debt Detection: Identifies and quantifies accumulating architectural issues before they become problematic

Advanced Security and Compliance Automation

• Dynamic Threat Modeling: Creates adaptive threat models for each API based on its specific context
• Automated Compliance Mapping: Maps all APIs to relevant regulatory frameworks (GDPR, HIPAA, SOC2)
• Defense-in-Depth Generation: Implements layered security controls with each API
• Cryptographic Policy Enforcement: Ensures proper encryption at rest and in transit

Intelligent Testing Matrix

• Behavior-Driven Test Generation: Creates tests that verify business requirements, not just technical functionality
• Chaos Testing Integration: Automatically generates resilience tests for unexpected conditions
• Automatic Edge Case Identification: Analyzes schemas to find and test boundary conditions
• Contract Testing Automation: Ensures backwards compatibility with dependent systems

Progressive Multi-Stage Deployment

• Environment-Specific Deployment Strategies: Tailors deployment approaches to each environment's risk profile
• Canary Analysis with Neural Feedback: Uses ML to detect subtle anomalies in canary deployments
• Automatic Rollback Decision Engine: Makes data-driven decisions about when to roll back based on complex heuristics
• Cross-Region Orchestration: Coordinates global deployments with region-specific compliance requirements

Adaptive User Experience

• Multi-Modal Interaction: Allows developers to seamlessly blend conversation, visual editing, and code
• Expertise-Adaptive Guidance: Provides different levels of assistance based on developer experience
• Context-Aware Documentation: Generates documentation tailored to the audience (developers, ops, business)
• Continuous Learning from Interactions: Improves recommendations based on team-specific patterns and preferences

This system fundamentally transforms API development from a technical implementation task to a collaborative creative process, where the system handles complexity, consistency, and quality while developers focus on the unique business value they provide. The neural foundation ensures it continuously improves, adapting to your organization's patterns and preferences over time.

By combining cutting-edge ML techniques with software engineering best practices, Fortitude enables organizations to develop and maintain complex API ecosystems with unprecedented speed, quality, and consistency.
