> **The self-learning LLM call.** Every call learns. Every call improves.

A Python library that wraps any LLM with file-based memory and automatic quality improvement. No database required.

```python
from netanel_core import LearningLLM

llm = LearningLLM(namespace="my-app")
result = llm.call("Write a function to validate emails")

print(result.response)  # The LLM's output
print(result.score)      # Quality score (0.0-1.0)
print(result.usage)      # Token usage for cost tracking
```

## ✨ Features

- 🧠 **Self-Learning** - Extracts patterns from every call, builds better context over time
- 📊 **Quality-First** - Auto-evaluation + retry loop, only stores high-quality outputs
- 💾 **File-Based Memory** - No database, human-readable `.md` files, git-trackable
- 🔄 **Prompt Evolution** - Auto-rewrites prompts based on learnings
- 🎯 **Bounded Safety** - Max retries, tokens, iterations (NASA-grade)
- 🤖 **DeepAgent Support** - Complex reasoning with LangGraph agents
- 💰 **Cost Tracking** - Token usage for all calls

---

## 🚀 Quick Start

```bash
pip install netanel-core
```

```python
from netanel_core import LearningLLM

llm = LearningLLM(namespace="my-app")
result = llm.call("Explain quantum computing simply")

if result.passed:
    print(result.response)
    print(f"Quality: {result.score:.2f}, Tokens: {result.usage['total_tokens']}")
```

---

## 📖 How It Works

Every `llm.call()` executes:

1. **RETRIEVE** - Load memories from namespace
2. **BUILD** - Create context (role + memories + task)
3. **CALL** - Invoke LLM
4. **EVALUATE** - Score quality (gpt-4o-mini + main model)
5. **RETRY** - If score < threshold, retry with feedback
6. **EXTRACT** - Extract patterns from successful responses
7. **STORE** - Save to `memories/{namespace}/patterns/`
8. **EVOLVE** - Trigger prompt improvements
9. **RETURN** - Result with response + metadata

## 💡 Usage Examples

### Custom Model

```python
from langchain_openai import ChatOpenAI

model = ChatOpenAI(model="gpt-4", temperature=0.7)
llm = LearningLLM(namespace="gpt4-app", model=model)
```

### DeepAgent Mode

```python
result = llm.call(
    "Research AI papers and summarize trends",
    use_agent=True  # Multi-step reasoning
)
print(f"Steps: {result.agent_steps}")
```

### Cost Tracking

```python
total = sum(llm.call(task).usage['total_tokens'] for task in tasks)
cost = (total / 1_000_000) * 0.375  # gpt-4o-mini avg
print(f"Cost: ${cost:.4f}")
```

---

## 🎯 Configuration

```python
from netanel_core import Config

config = Config(
    namespace="my-app",
    quality_threshold=0.8,
    max_retries=3,
    memories_dir="./memories",
)

llm = LearningLLM(config=config)
```

Or YAML:

```yaml
namespace: my-app
quality_threshold: 0.8
max_retries: 3
```

```python
config = Config.from_yaml("config.yaml")
```
