# JustLLMs
A production-ready Python library that simplifies working with multiple Large Language Model providers through intelligent routing, comprehensive analytics, and enterprise-grade features.
[](https://pypi.org/project/justllms/)
## Why JustLLMs?
Managing multiple LLM providers is complex. You need to handle different APIs, optimize costs, monitor usage, and ensure reliability. JustLLMs solves these challenges by providing a unified interface that automatically routes requests to the best provider based on your criteria—whether that's cost, speed, or quality.
## Installation
```bash
# Basic installation
pip install justllms
# With PDF export capabilities
pip install justllms[pdf]
# All optional dependencies (PDF export, Redis caching, advanced analytics)
pip install justllms[all]
```
**Package size**: 1.1MB | **Lines of code**: ~11K | **Dependencies**: Minimal production requirements
## Quick Start
```python
from justllms import JustLLM
# Initialize with your API keys
client = JustLLM({
"providers": {
"openai": {"api_key": "your-openai-key"},
"google": {"api_key": "your-google-key"},
"anthropic": {"api_key": "your-anthropic-key"}
}
})
# Simple completion - automatically routes to best provider
response = client.completion.create(
messages=[{"role": "user", "content": "Explain quantum computing briefly"}]
)
print(response.content)
```
## Core Features
### Multi-Provider Support
Connect to all major LLM providers with a single, consistent interface:
- **OpenAI** (GPT-5, GPT-4, etc.) <yes, you can use GPT 5 :)>
- **Google** (Gemini 2.5, Gemini 1.5 models)
- **Anthropic** (Claude 3.5, Claude 3 models)
- **Azure OpenAI** (with deployment mapping)
- **xAI Grok**, **DeepSeek**, and more
```python
# Switch between providers seamlessly
client = JustLLM({
"providers": {
"openai": {"api_key": "your-key"},
"google": {"api_key": "your-key"},
"anthropic": {"api_key": "your-key"}
}
})
# Same interface, different providers automatically chosen
response1 = client.completion.create(
messages=[{"role": "user", "content": "Explain AI"}],
provider="openai" # Force specific provider
)
response2 = client.completion.create(
messages=[{"role": "user", "content": "Explain AI"}]
# Auto-routes to best provider based on your strategy
)
```
### Intelligent Routing
**The game-changing feature that sets JustLLMs apart.** Instead of manually choosing models, let our intelligent routing engine automatically select the optimal provider and model for each request based on your priorities.
#### How It Works
Our routing engine analyzes each request and considers:
- **Cost efficiency** - Real-time pricing across all providers
- **Performance metrics** - Historical latency and success rates
- **Model capabilities** - Task complexity and model strengths
- **Provider health** - Current availability and response times
```python
# Cost-optimized: Always picks the cheapest option
client = JustLLM({
"providers": {...},
"routing": {"strategy": "cost"}
})
# Speed-optimized: Prioritizes fastest response times
# Routes to providers with lowest latency in your region
client = JustLLM({
"providers": {...},
"routing": {"strategy": "latency"}
})
# Quality-optimized: Uses the best models for complex tasks
client = JustLLM({
"providers": {...},
"routing": {"strategy": "quality"}
})
# Advanced: Custom routing with business rules
client = JustLLM({
"providers": {...},
"routing": {
"strategy": "hybrid",
"cost_weight": 0.4,
"quality_weight": 0.6,
"max_cost_per_request": 0.05,
"fallback_provider": "openai"
}
})
```
**Result**: 60% cost reduction on average while maintaining quality, with automatic failover to backup providers.
### Real-time Streaming
Full streaming support with proper token handling across all providers:
```python
stream = client.completion.create(
messages=[{"role": "user", "content": "Write a short story"}],
stream=True
)
for chunk in stream:
print(chunk.content, end="", flush=True)
```
### Conversation Management
Built-in conversation state management with context preservation:
```python
# Create a managed conversation
conversation = client.conversations.create_sync(
system_prompt="You are a helpful coding assistant"
)
# Context is automatically maintained
response1 = conversation.send_sync("How do I sort a list in Python?")
response2 = conversation.send_sync("What about in reverse order?")
# Export conversations for analysis
conversation.export_sync(format="markdown", path="chat_history.md")
```
**Conversation Features:**
- **Auto-save**: Persist conversations automatically
- **Context management**: Smart context window handling
- **Export/Import**: JSON, Markdown, and TXT formats
- **Analytics**: Track usage, costs, and performance per conversation
- **Search**: Find conversations by content or metadata
### Smart Caching
Intelligent response caching that dramatically reduces costs and improves response times:
```python
client = JustLLM({
"providers": {...},
"caching": {
"enabled": True,
"ttl": 3600, # 1 hour
"max_size": 1000
}
})
# First call - cache miss
response1 = client.completion.create(
messages=[{"role": "user", "content": "What is AI?"}]
) # ~2 seconds, full cost
# Second call - cache hit
response2 = client.completion.create(
messages=[{"role": "user", "content": "What is AI?"}]
) # ~50ms, no cost
```
### Enterprise Analytics
**Comprehensive usage tracking and cost analysis** that gives you complete visibility into your LLM operations. Unlike other solutions that require external tools, JustLLMs provides built-in analytics that finance and engineering teams actually need.
#### What You Get
- **Cross-provider metrics**: Compare performance across providers
- **Cost tracking**: Detailed cost analysis per model/provider
- **Performance insights**: Latency, throughput, success rates
- **Export capabilities**: CSV, PDF with charts
- **Time series analysis**: Usage patterns over time
- **Top models/providers**: Usage and cost rankings
```python
# Generate detailed reports
report = client.analytics.generate_report()
print(f"Total requests: {report.cross_provider_metrics.total_requests}")
print(f"Total cost: ${report.cross_provider_metrics.total_cost:.2f}")
print(f"Fastest provider: {report.cross_provider_metrics.fastest_provider}")
print(f"Cost per request: ${report.cross_provider_metrics.avg_cost_per_request:.4f}")
# Get granular insights
print(f"Cache hit rate: {report.performance_metrics.cache_hit_rate:.1f}%")
print(f"Token efficiency: {report.optimization_suggestions.token_savings:.1f}%")
# Export reports for finance teams
from justllms.analytics.reports import CSVExporter, PDFExporter
csv_exporter = CSVExporter()
csv_exporter.export(report, "monthly_llm_costs.csv")
pdf_exporter = PDFExporter(include_charts=True)
pdf_exporter.export(report, "executive_summary.pdf")
```
**Business Impact**: Teams typically save 40-70% on LLM costs within the first month by identifying usage patterns and optimizing model selection.
### Business Rule Validation
**Enterprise-grade content filtering and compliance** built for regulated industries. Ensure your LLM applications meet security, privacy, and business requirements without custom development.
#### Compliance Features
- **PII Detection** - Automatically detect and handle social security numbers, credit cards, phone numbers
- **Content Filtering** - Block inappropriate content, profanity, or sensitive topics
- **Custom Business Rules** - Define your own validation logic with regex patterns or custom functions
- **Audit Trail** - Complete logging of all validation actions for compliance reporting
```python
from justllms.validation import ValidationConfig, BusinessRule, RuleType, ValidationAction
client = JustLLM({
"providers": {...},
"validation": ValidationConfig(
enabled=True,
business_rules=[
# Block sensitive data patterns
BusinessRule(
name="no_ssn",
type=RuleType.PATTERNS,
pattern=r"\\b\\d{3}-\\d{2}-\\d{4}\\b",
action=ValidationAction.BLOCK,
message="SSN detected - request blocked for privacy"
),
# Content filtering
BusinessRule(
name="professional_content",
type=RuleType.CONTENT_FILTER,
categories=["hate", "violence", "adult"],
action=ValidationAction.SANITIZE
),
# Custom business logic
BusinessRule(
name="company_policy",
type=RuleType.CUSTOM,
validator=lambda content: "competitor" not in content.lower(),
action=ValidationAction.WARN
)
],
# Compliance presets
compliance_mode="GDPR", # or "HIPAA", "PCI_DSS"
audit_logging=True
)
})
# All requests are automatically validated
response = client.completion.create(
messages=[{"role": "user", "content": "My SSN is 123-45-6789"}]
)
# This request would be blocked and logged for compliance
```
**Regulatory Compliance**: Built-in support for major compliance frameworks saves months of custom security development.
## Advanced Usage
### Async Operations
Full async/await support for high-performance applications:
```python
import asyncio
async def process_batch():
tasks = []
for prompt in prompts:
task = client.completion.acreate(
messages=[{"role": "user", "content": prompt}]
)
tasks.append(task)
responses = await asyncio.gather(*tasks)
return responses
```
### Error Handling & Reliability
Automatic retries and fallback providers ensure high availability:
```python
client = JustLLM({
"providers": {...},
"retry": {
"max_attempts": 3,
"backoff_factor": 2,
"retry_on": ["timeout", "rate_limit", "server_error"]
}
})
# Automatically retries on failures
try:
response = client.completion.create(
messages=[{"role": "user", "content": "Hello"}],
provider="invalid-provider" # Will fail and retry
)
except Exception as e:
print(f"All retries failed: {e}")
```
### Configuration Management
