hyperllm 1.0.1

A unified interface for multiple LLM providers with caching and interactive development mode to get massive cost savings.

HyperLLM

A unified Python interface for multiple LLM providers with intelligent caching and cost-saving interactive development mode. Stop burning money on API calls during development - use interactive mode to prototype with real LLMs at zero api cost!

🚀 Why HyperLLM?

Save Development Costs: Interactive mode eliminates expensive API calls during prototyping. Copy prompts to your clipboard, paste responses back, and build your application without the API meter running.

Provider Freedom: Switch between OpenAI, Anthropic, local Ollama, or any custom API with a single line of code. No vendor lock-in, no rewriting.

Smart Caching: Never pay for the same prompt twice. Responses are automatically cached and reused across development and production.

Developer Experience: Built by developers, for developers. Clipboard integration, file I/O, and seamless workflows that just work.

✨ Features

• 🔄 Unified Interface: One API for all LLM providers - OpenAI, Anthropic, Ollama, and more
• 💰 Cost-Saving Interactive Mode: Develop without API costs using copy-paste workflow
• 💾 Intelligent Caching: Automatic response caching with prompt-based deduplication
• 🔌 Extensible Provider System: Easy to add new providers or custom APIs
• 📋 Clipboard Integration: Automatic prompt copying for seamless workflows
• 📁 File I/O Support: Read prompts from and write responses to files
• 🛡️ Production Ready: Robust error handling, validation, and monitoring
• 🎯 Zero Configuration: Works out of the box with sensible defaults

📦 Installation

# Basic installation
pip install hyperllm

# With specific provider support
pip install hyperllm[openai]      # OpenAI GPT models
pip install hyperllm[anthropic]   # Anthropic Claude models  
pip install hyperllm[clipboard]   # Enhanced clipboard features

# Install everything
pip install hyperllm[all]

🚀 Quick Start

from hyperllm import HyperLLM

# Initialize once, use everywhere
interface = HyperLLM()

# Configure your preferred provider
interface.set_llm('openai', 
                  api_key='your-api-key', 
                  model='gpt-4')

# Get responses (cached automatically)
response = interface.get_response("Explain quantum computing simply")
print(response)

# Subsequent identical prompts use cache - zero cost!
cached_response = interface.get_response("Explain quantum computing simply")

🔥 Interactive Development Mode

The game-changer for LLM development costs:

# Enable interactive mode - save money during development!
export LLM_INTERACTIVE_MODE=true

from hyperllm import HyperLLM

interface = HyperLLM()
interface.set_llm('openai')  # Provider doesn't matter in interactive mode

# This copies prompt to clipboard and waits for your response
response = interface.get_response("Write a Python function to sort a list")

# Workflow:
# 1. Prompt automatically copied to clipboard ✨  
# 2. Paste into ChatGPT/Claude/etc.
# 3. Copy response and paste back
# 4. Response cached for production use
# 5. Zero API costs during development! 💰

Perfect for:

• Prompt engineering and iteration
• Building demos and prototypes
• Testing different prompt variations
• Learning and experimentation

🌐 Supported Providers

OpenAI GPT Models

interface.set_llm('openai',
                  api_key='sk-...',
                  model='gpt-4o',           # or gpt-3.5-turbo, gpt-4, etc.
                  temperature=0.7,
                  max_tokens=2000)

Anthropic Claude

interface.set_llm('anthropic',          # or 'claude'
                  api_key='sk-ant-...',
                  model='claude-3-sonnet-20240229',
                  max_tokens=2000)

Local Ollama

interface.set_llm('ollama',
                  base_url='http://localhost:11434',
                  model='llama2',         # or codellama, mistral, etc.
                  temperature=0.7)

Custom APIs (OpenAI Compatible)

interface.set_llm('custom',
                  base_url='https://api.your-provider.com',
                  api_key='your-key',
                  model='your-model',
                  headers={'Custom-Header': 'value'})

Check Available Providers

from hyperllm import get_available_providers

providers = get_available_providers()
for name, info in providers.items():
    status = "✅ Available" if info['available'] else "❌ Missing deps"
    print(f"{name}: {status}")

💾 Smart Caching System

Responses are automatically cached using prompt hashing:

# First call - hits API/interactive mode
response1 = interface.get_response("What is machine learning?")

# Subsequent calls - instant cache retrieval, zero cost
response2 = interface.get_response("What is machine learning?") 

# Manage cache
stats = interface.get_cache_stats()
print(f"Cached responses: {stats['total_entries']}")

interface.clear_cache()  # Clean slate when needed

🛠️ Advanced Usage

One-Line Setup

from hyperllm import create_interface

# Create and configure in one step
interface = create_interface('anthropic',
                           cache_dir='/custom/cache',
                           api_key='sk-ant-...',
                           model='claude-3-opus-20240229')

File-Based Workflows

# Configure file I/O for automated workflows
export PROMPT_OUTPUT_FILE="/tmp/prompt.txt"
export RESPONSE_INPUT_FILE="/tmp/response.txt"  
export LLM_INTERACTIVE_MODE=true

Provider Comparison

# Easy A/B testing between providers
providers = [
    ('openai', {'model': 'gpt-4'}),
    ('anthropic', {'model': 'claude-3-sonnet-20240229'}),
    ('ollama', {'model': 'llama2'})
]

for name, config in providers:
    interface.set_llm(name, **config)
    response = interface.get_response("Compare these approaches...")
    print(f"{name}: {response[:100]}...")

Custom Provider Registration

from hyperllm.providers import register_provider, BaseLLMProvider

class MyProvider(BaseLLMProvider):
    def validate_config(self):
        return True
    
    def _setup_client(self):
        pass
        
    def generate_response(self, prompt, **kwargs):
        return f"Custom response for: {prompt}"

# Register and use
register_provider('myprovider', MyProvider)
interface.set_llm('myprovider')

🎯 Real-World Examples

Development to Production Pipeline

import os
from hyperllm import HyperLLM

# Development phase - zero API costs
os.environ['LLM_INTERACTIVE_MODE'] = 'true'

interface = HyperLLM()
interface.set_llm('openai')

# Build your prompts interactively
prompts = [
    "Generate a REST API design for a blog",
    "Write error handling for user authentication", 
    "Create database schema for user profiles"
]

for prompt in prompts:
    response = interface.get_response(prompt)
    # Responses cached automatically

# Production deployment - use cached responses + API
os.environ['LLM_INTERACTIVE_MODE'] = 'false'
interface.set_llm('openai', api_key=os.environ['OPENAI_API_KEY'])

# Cached responses used when available, new prompts hit API
response = interface.get_response("Generate a REST API design for a blog")  # From cache!
new_response = interface.get_response("Add OAuth2 to the API")  # New API call

Multi-Model Analysis

# Compare responses across providers effortlessly
interface = HyperLLM()
test_prompt = "Explain the trade-offs of microservices architecture"

results = {}
for provider in ['openai', 'anthropic', 'ollama']:
    try:
        interface.set_llm(provider, **provider_configs[provider])
        results[provider] = interface.get_response(test_prompt)
    except Exception as e:
        results[provider] = f"Error: {e}"

# Analyze differences in responses
for provider, response in results.items():
    print(f"\n=== {provider.title()} ===")
    print(response)

Adding New Providers

We're always looking for new LLM provider integrations! Here's how to add one:

1. Create Provider File

   # hyperllm/providers/newprovider_provider.py
   from .base import BaseLLMProvider
   
   class NewProviderProvider(BaseLLMProvider):
       def validate_config(self):
           # Validate configuration
           pass
           
       def _setup_client(self):
           # Initialize client
           pass
           
       def generate_response(self, prompt, **kwargs):
           # Implement response generation
           pass
   

2. Register Provider

   # Add to hyperllm/providers/__init__.py
   from .newprovider_provider import NewProviderProvider
   
   PROVIDER_REGISTRY['newprovider'] = NewProviderProvider
   

3. Add Tests

   # tests/test_providers/test_newprovider.py
   import unittest
   from hyperllm.providers.newprovider_provider import NewProviderProvider
   
   class TestNewProviderProvider(unittest.TestCase):
       def test_validation(self):
           # Test provider validation
           pass
   

4. Update Documentation

   • Add usage example to README
   • Document configuration options
   • Add to provider comparison table

Code Style
