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

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())
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)
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)
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)
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)
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.
