# stratum-llm
|
|
|
|
Unified LLM abstraction for the stratumiops ecosystem with automatic provider detection, fallback chains, and smart caching.
|
|
|
|
## Features
|
|
|
|
- **Credential Auto-detection**: Automatically finds CLI credentials (Claude, OpenAI) and API keys
|
|
- **Provider Fallback**: Circuit breaker pattern with automatic failover across providers
|
|
- **Smart Caching**: xxHash-based request deduplication reduces duplicate API calls
|
|
- **Kogral Integration**: Inject project context from knowledge base (optional)
|
|
- **Cost Tracking**: Transparent cost estimation across all providers
|
|
- **Multiple Providers**: Anthropic Claude, OpenAI, DeepSeek, Ollama
|
|
|
|
## Quick Start
|
|
|
|
```rust
|
|
use stratum_llm::{UnifiedClient, Message, Role};
|
|
|
|
#[tokio::main]
|
|
async fn main() -> Result<(), Box<dyn std::error::Error>> {
|
|
let client = UnifiedClient::auto()?;
|
|
|
|
let messages = vec![
|
|
Message {
|
|
role: Role::User,
|
|
content: "What is Rust?".to_string(),
|
|
}
|
|
];
|
|
|
|
let response = client.generate(&messages, None).await?;
|
|
println!("{}", response.content);
|
|
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
## Provider Priority
|
|
|
|
1. **CLI credentials** (subscription-based, no per-token cost) - preferred
|
|
2. **API keys** from environment variables
|
|
3. **Local models** (Ollama)
|
|
|
|
The client automatically detects available credentials and builds a fallback chain.
|
|

## Advanced Usage
|
|
|
|
### With Kogral Context
|
|
|
|
```rust
|
|
let client = UnifiedClient::builder()
|
|
.auto_detect()?
|
|
.with_kogral()
|
|
.build()?;
|
|
|
|
let response = client
|
|
.generate_with_kogral(&messages, None, Some("rust"), None)
|
|
.await?;
|
|
```
|
|
|
|
### Custom Fallback Strategy
|
|
|
|
```rust
|
|
use stratum_llm::{FallbackStrategy, ProviderChain};
|
|
|
|
let chain = ProviderChain::from_detected()?
|
|
.with_strategy(FallbackStrategy::OnRateLimitOrUnavailable);
|
|
|
|
let client = UnifiedClient::builder()
|
|
.with_chain(chain)
|
|
.build()?;
|
|
```
|
|
|
|
### Cost Budget
|
|
|
|
```rust
|
|
let chain = ProviderChain::from_detected()?
|
|
.with_strategy(FallbackStrategy::OnBudgetExceeded {
|
|
budget_cents: 10.0,
|
|
});
|
|
```
|
|
