What is Unify?
Unify is an AI platform that unifies and simplifies the LLM landscape by providing a single universal API interface to access any large language model from any provider. The platform lets developers use all LLMs from all providers by simply changing one string in their code, eliminating the need to manage multiple API keys or handle different input-output formats across different model providers.
Key features include: a single common interface for all models and providers, one account with one balance and one API key, support for custom fine-tuned and local LLMs, the ability to benchmark prompts across all models and providers with custom tests and evals, and intelligent routing to the best LLM for each individual prompt based on quality, cost, and speed. The platform offers both a Python client (pip install unifyai) and a REST API for direct queries.
Unify is designed for developers, AI engineers, and teams building LLM-powered applications who need to access multiple model providers without managing complex integrations. It's particularly valuable for companies that want to compare models, optimize costs, and route prompts to the most appropriate model for each task. The platform supports production-grade apps and scales from new projects to enterprise deployments.
The platform removes unnecessary LLM abstractions, making it easy to get LLM flywheels spinning for new projects and seamlessly scale them to production. Users can list all supported models, endpoints, and providers through the client, and the REST API allows direct querying without the Python wrapper.
Unify pricing
Pricing model: Free
The website does not explicitly disclose detailed pricing tiers, free tier limits, or paid plan costs. Users need to obtain an API key from the Unify Console to start using the platform. Pricing appears to be based on a unified balance system where one account balance covers all models and providers. The platform charges for model usage through this single balance rather than separate provider bills. Specific pricing details, free tier availability, and plan comparisons are not publicly listed on the main website and would require contacting Unify or checking the Console after account creation.

Frequently asked questions about Unify
What is Unify?
Unify is a platform that unifies and simplifies the LLM landscape by providing a single universal API interface to access any large language model from any provider. It lets you use all LLMs from all providers by simply changing one string in your code, without managing multiple API keys or handling different input-output formats.
How do I get started with Unify?
Get started by installing the Python client with 'pip install unifyai', then obtain your API key from the Unify Console. Import the unify module, create a client with your API key and desired model endpoint (e.g., client = unify.Unify('gpt-4o@openai', api_key=your_key)), and call client.generate() with your prompt.
What models and providers does Unify support?
Unify supports all LLMs from all providers through its universal API. You can list all supported models, endpoints, and providers using unify.list_models(), unify.list_providers(), and unify.list_endpoints(). The platform works with major providers like OpenAI and supports filtering by provider or model name.
How do I switch between different models?
Switch between models by simply changing one string in your client initialization. For example, change from 'gpt-4o@openai' to another model endpoint like 'llama-3-8b-chat@provider'. No need to change API keys or reconfigure your application.
Can I use my own custom or fine-tuned models?
Yes, Unify supports integrations for your own fine-tuned models and local LLMs. This allows you to bring your custom models into the unified interface alongside provider models.
How does routing to the best LLM work?
Unify allows you to route to the perfect model and provider for each individual prompt to improve quality, cost, and speed. You can benchmark your prompts across all models and providers, compare their performance metrics, and iterate on your system prompt until test cases pass.
Is there a Python client or just REST API?
Unify offers both a Python client (unifyai package) and a REST API. The Python client is built directly on top of the REST API, so you can query the REST API directly using curl or other HTTP clients if needed.
How do I list available models and endpoints?
Use the Python client functions: unify.list_models() for all models, unify.list_providers() for all providers, and unify.list_endpoints() for all endpoints. You can also filter by provider or model, like unify.list_models('openai') or unify.list_endpoints(provider='openai').
What is the Universal API?
The Universal API is Unify's single, common interface for all models and providers. It provides one account with one balance and one API key that works across all LLMs from all providers, eliminating the complexity of managing multiple provider APIs.
Can I use Unify without Python?
Yes, while the Python client is the easiest way to get started, you can query the REST API directly using any HTTP client. The REST API endpoint is 'https://api.unify.ai/v0/endpoints' and requires a Bearer token in the Authorization header.
