Free AI Stack: Run Claude + Ollama + Gemini with Zero Monthly Cost

Building a production AI system using only free tiers is a challenging task, but it's achievable with the right combination of tools and smart routing. In this guide, we'll explore how to build a production AI system using Anthropic Claude, Ollama, Google Gemini Flash, and Groq, all of which offer generous free tiers.

System Architecture

Our system architecture will consist of the following components:

  • Inference Engine: Anthropic Claude (generous free tier) for text-based inference tasks
  • Local AI Model: Ollama (local) for running custom AI models
  • Knowledge Graph: Google Gemini Flash (free) for knowledge graph-based queries
  • Computational Engine: Groq (free) for computationally intensive tasks

Here's an ASCII architecture diagram:

                                      +---------------+
                                      |  User Request  |

Smart Routing

To minimize costs, we'll implement a smart routing layer that directs user requests to the most cost-effective component. The routing layer will consider the type of request, the required computational resources, and the availability of free tier resources.

Here's an example of how the routing layer could work:

import requests

def route_request(request):
    if request['type'] == 'text_inference':
        # Use Anthropic Claude for text-based inference tasks
        return 'anthropic_claude'
    elif request['type'] == 'custom_ai_model':
        # Use Ollama for custom AI models
        return 'ollama'
    elif request['type'] == 'knowledge_graph_query':
        # Use Google Gemini Flash for knowledge graph-based queries
        return 'google_gemini_flash'
    elif request['type'] == 'computational_task':
        # Use Groq for computationally intensive tasks
        return 'groq'
    else:
        # Default to Anthropic Claude
        return 'anthropic_claude'

# Example usage:
request = {'type': 'text_inference', 'query': 'What is the capital of France?'}
route = route_request(request)
if route == 'anthropic_claude':
    # Call Anthropic Claude API
    response = requests.post('https://api.anthropic.com/claude', json=request)
    print(response.json())
Enter fullscreen mode Exit fullscreen mode

Anthropic Claude (Inference Engine)

Anthropic Claude is a text-based inference engine that offers a generous free tier. We'll use Claude for text-based inference tasks, such as answering questions or generating text.

Here's an example of how to use the Anthropic Claude API:

import requests

def query_claude(query):
    api_url = 'https://api.anthropic.com/claude'
    headers = {'Content-Type': 'application/json'}
    data = {'query': query}
    response = requests.post(api_url, headers=headers, json=data)
    return response.json()

# Example usage:
query = 'What is the capital of France?'
response = query_claude(query)
print(response)
Enter fullscreen mode Exit fullscreen mode

Ollama (Local AI Model)

Ollama is a local AI model that allows you to run custom AI models on your own hardware. We'll use Ollama for custom AI models that require low-latency inference.

Here's an example of how to use Ollama:

import ollama

def load_model(model_path):
    model = ollama.load_model(model_path)
    return model

def run_model(model, input_data):
    output = model(input_data)
    return output

# Example usage:
model_path = 'path/to/model.pth'
model = load_model(model_path)
input_data = 'This is an example input'
output = run_model(model, input_data)
print(output)
Enter fullscreen mode Exit fullscreen mode

Google Gemini Flash (Knowledge Graph)

Google Gemini Flash is a knowledge graph-based API that offers a free tier. We'll use Gemini Flash for knowledge graph-based queries, such as entity disambiguation or relationship extraction.

Here's an example of how to use the Google Gemini Flash API:

import requests

def query_gemini(query):
    api_url = 'https://api.google.com/gemini/v1/query'
    headers = {'Content-Type': 'application/json'}
    data = {'query': query}
    response = requests.post(api_url, headers=headers, json=data)
    return response.json()

# Example usage:
query = 'What is the relationship between Elon Musk and Tesla?'
response = query_gemini(query)
print(response)
Enter fullscreen mode Exit fullscreen mode

Groq (Computational Engine)

Groq is a computational engine that offers a free tier. We'll use Groq for computationally intensive tasks, such as data processing or scientific simulations.

Here's an example of how to use the Groq API:

import requests

def run_task(task):
    api_url = 'https://api.groq.com/v1/tasks'
    headers = {'Content-Type': 'application/json'}
    data = {'task': task}
    response = requests.post(api_url, headers=headers, json=data)
    return response.json()

# Example usage:
task = 'matrix_multiplication'
response = run_task(task)
print(response)
Enter fullscreen mode Exit fullscreen mode

Monthly Cost Breakdown

Here's a breakdown of the estimated monthly costs for each component:

  • Anthropic Claude (Inference Engine): $0 (free tier)
  • Ollama (Local AI Model): $0 (free tier)
  • Google Gemini Flash (Knowledge Graph): $0 (free tier)
  • Groq (Computational Engine): $0 (free tier)

Total estimated monthly cost: $0

Note that these estimates are subject to change and may vary depending on usage patterns and other factors.

Conclusion

Building a production AI system using only free tiers is a challenging task, but it's achievable with the right combination of tools and smart routing. By leveraging Anthropic Claude, Ollama, Google Gemini Flash, and Groq, we can build a robust and scalable AI system that meets the needs of most use cases. With smart routing and careful resource management, we can minimize costs and keep the system running at $0 per month.
