Advanced Features

Cost Optimization

Model Router

Automatically routes requests to cost-effective models based on task complexity:

use kaccy_ai::llm::{ModelRouter, TaskComplexity};

let router = ModelRouter::new(routing_config);

// Simple tasks → Gemini Flash (cheapest)
let result = router.route_and_execute(&simple_request, TaskComplexity::Simple).await?;

// Complex tasks → GPT-4 Turbo or Claude Opus (most capable)
let result = router.route_and_execute(&complex_request, TaskComplexity::High).await?;

LLM Cache

use kaccy_ai::llm::{CachedLlmClient, LlmCacheConfig};

let cache_config = LlmCacheConfig {
    ttl_seconds: 3600,
    max_entries: 1000,
    enable_semantic_similarity: true,
    similarity_threshold: 0.95,
};

let cached_client = CachedLlmClient::new(llm_client, cache_config);

Request Batching

use kaccy_ai::llm::BatchProcessor;

let batch_processor = BatchProcessor::new(max_batch_size, wait_time_ms);

Resilience & Reliability

Token-Gated AI Access

Create tiered AI access based on token holdings:

use kaccy_ai::{AccessControlManager, AccessTier, TokenHolder, AiFeature};
use rust_decimal_macros::dec;

let mut access_manager = AccessControlManager::new();

let holder = TokenHolder {
    token_id: "token123".to_string(),
    user_id: "user456".to_string(),
    balance: dec!(50000), // Silver tier (10k-100k tokens)
};

// Check access to features
if access_manager.check_access(&holder, AiFeature::CodeEvaluation)? {
    // User has access to code evaluation
}

// Get feature quota
let quota = access_manager.get_feature_quota(&holder, AiFeature::BatchProcessing)?;
println!("Batch processing quota: {} requests/day", quota.max_requests_per_day);

Access Tiers:

• Silver (10k-100k): Batch processing, custom agents (up to 3)
• Gold (100k-1M): Priority support, advanced features, custom agents (up to 10)
• Platinum (1M+): Unlimited access, dedicated support, custom agents (unlimited)

Knowledge Base

Store and retrieve domain-specific knowledge:

use kaccy_ai::{KnowledgeBase, KnowledgeDomain, KnowledgeEntry};

let mut kb = KnowledgeBase::new();

kb.add_entry(KnowledgeEntry {
    id: "rust-001".to_string(),
    domain: KnowledgeDomain::Programming,
    title: "Rust Ownership Rules".to_string(),
    content: "Each value has a single owner...".to_string(),
    tags: vec!["rust".to_string(), "ownership".to_string()],
    metadata: Default::default(),
});

let results = kb.search("ownership rules", Some(KnowledgeDomain::Programming), 5)?;

Reputation Prediction

Predict future commitment success based on historical data:

use kaccy_ai::{ReputationPredictor, IssuerHistory};

let predictor = ReputationPredictor::new(llm_client);

let history = IssuerHistory {
    issuer_id: "issuer123".to_string(),
    commitments: vec![/* historical commitments */],
    total_commitments: 50,
    completed_commitments: 45,
    failed_commitments: 5,
    average_completion_time_days: 7.5,
};

let prediction = predictor.predict_commitment_success(&history, "New commitment").await?;
println!("Success probability: {}%, Risk: {:?}",
    prediction.success_probability * 100.0, prediction.risk_level);

GitHub Integration

Comprehensive GitHub verification:

use kaccy_ai::{GitHubClient, GitHubVerifier};

let github_client = GitHubClient::new("github-token".to_string());
let github_verifier = GitHubVerifier::new(github_client);

// Verify commit
let commit_result = github_verifier.verify_commit(
    "https://github.com/owner/repo",
    "commit-sha",
    Some("expected_author")
).await?;

// Verify release
let release_result = github_verifier.verify_release(
    "https://github.com/owner/repo",
    "v1.0.0",
    "Release notes should mention feature X"
).await?;

// Verify PR/Issue closure
let pr_result = github_verifier.verify_pr(
    "https://github.com/owner/repo/pull/123",
    Some("author")
).await?;

use kaccy_ai::{DocumentParser, PdfParser, QualityAnalyzer};

// Parse PDF
let pdf_parser = PdfParser::new();
let (text, metadata) = pdf_parser.parse_file("document.pdf")?;

// Analyze document quality
let quality_analyzer = QualityAnalyzer::new();
let quality = quality_analyzer.analyze(&text)?;
println!("Readability: {}, Grammar: {}", quality.readability, quality.grammar);

Configuration Presets

Use pre-configured settings for different environments:

use kaccy_ai::presets::{
    DevelopmentPreset,
    ProductionPreset,
    HighVolumePreset,
    CostOptimizedPreset
};

// Development: Fast feedback, lower costs
let dev_config = DevelopmentPreset::evaluator_config();
let dev_oracle = DevelopmentPreset::oracle_config();

// Production: High reliability, quality
let prod_config = ProductionPreset::evaluator_config();
let prod_circuit = ProductionPreset::circuit_breaker_config();

// High Volume: Maximum throughput
let hv_batch = HighVolumePreset::batch_config();
let hv_cache = HighVolumePreset::cache_config();

// Cost Optimized: Minimal cost
let cost_routing = CostOptimizedPreset::routing_config();

Service Hub

Use the high-level service hub for simplified configuration:

use kaccy_ai::{AiServiceBuilder, AiServiceHub};

let service = AiServiceBuilder::new()
    .with_openai("openai-key")
    .with_anthropic("anthropic-key")
    .with_gemini("gemini-key")
    .with_github("github-token")
    .enable_oracle()
    .enable_access_control()
    .build()?;

// Use all services through a single hub
let evaluator = service.evaluator()?;
let verifier = service.verifier()?;
let fraud_detector = service.fraud_detector()?;
let oracle = service.oracle()?;

Cost Management

Estimated costs per operation (using GPT-4 Turbo as baseline):

Cost Optimization Strategies:

1. Use Gemini Flash for simple tasks ($0.000075/1k tokens - 200x cheaper)
2. Enable caching for repeated requests (50-90% cost reduction)
3. Use batch processing to reduce overhead
4. Route by complexity (simple → cheap, complex → powerful)

Safety & Security

• Rate Limiting: Prevents API cost overruns
• Circuit Breakers: Protects against cascading failures
• Human-in-the-Loop: Escalates uncertain cases
• Audit Logging: Comprehensive decision tracking
• Input Validation: Prevents injection attacks
• Quota Management: Per-tier usage limits

Dependencies

Core dependencies:

• tokio - Async runtime
• reqwest - HTTP client
• serde / serde_json - Serialization
• async-trait - Async traits
• thiserror - Error handling
• tracing - Logging and observability

Specialized:

• lopdf - PDF parsing
• image - Image processing
• regex - Pattern matching
• rust_decimal - Precise decimal math
