What is Kolank?
Kolank is a comprehensive Generative AI Hub that provides a unified API for seamless access to dozens of large language models (LLMs) from multiple providers including OpenAI, Anthropic, Google, Mistral, Meta, Cohere, and more. It optimizes AI costs through pay-for-performance query routing, automatically directing queries to the most cost-effective and suitable model for each task. Developers can access over 100 different LLMs through a single API endpoint, eliminating the need to manage multiple API keys and integrations.
Key features include intelligent model selection that automatically routes requests to optimal text, image, or video models based on task requirements, load balancing to distribute requests across providers, automatic fallbacks when models experience downtime, and detailed cost and performance metrics for tracking usage. Kolank supports the Agent-to-Agent (A2A) protocol enabling AI agents to communicate and collaborate, streaming responses, JSON mode output, tool/function calling, and full compatibility with the OpenAI API format for easy integration.
Kolank is designed for developers, AI engineers, startups, and organizations building AI-powered applications who want to reduce LLM costs while maintaining response quality. It's particularly valuable for companies using multiple AI models, those looking to optimize AI spending, developers who want to test different models without managing separate integrations, and businesses needing reliable AI infrastructure with built-in redundancy and failover capabilities.
Kolank pricing
Pricing model: Paid
Kolank uses a pay-as-you-go pricing model starting at $0.25 per unit. Pricing is token-based and varies by model - for example: Meta-llama/Meta-Llama-3-8B-Instruct costs $0.08 per 1K input/output tokens, openai/gpt-3.5-turbo-0125 costs $0.13 per 1M tokens input/output, Anthropic/claude-3-haiku costs $0.25/$1.25 per 1M tokens input/output, openai/gpt-4o costs $5/$15 per 1M tokens input/output, and Anthropic/claude-3-opus costs $15/$75 per 1M tokens input/output. Image input pricing is also available for vision models (e.g., $2.5 per 1K images for gpt-4o-mini). No free tier is explicitly mentioned on the website.

Frequently asked questions about Kolank
What is Kolank?
Kolank is a comprehensive Generative AI Hub that provides a unified API for seamless access to all major AI models including over 100 LLMs from providers like OpenAI, Anthropic, Google, Mistral, Meta, and Cohere. It optimizes AI costs through pay-for-performance query routing and intelligent model selection.
How do I integrate Kolank into my application?
Integration is simple - just replace your OpenAI settings: update BASE_URL to https://kolank.com/api/v1, replace OPENAI_API_KEY with your KOLANK_API_KEY from kolank.com/keys, and set MODEL to any of Kolank's supported model names. Full code examples are provided for Python, JavaScript, and curl.
What AI models are available through Kolank?
Kolank provides access to 100+ LLMs including OpenAI models (gpt-4o, gpt-4, gpt-3.5-turbo, o1-preview, o1-mini), Anthropic models (claude-3-haiku, claude-3-opus, claude-3-sonnet), Google models (gemini-flash-1.5, gemini-pro, gemini-pro-1.5), Mistral models (mistral-large, mistral-small, Mixtral), Meta Llama models (llama-3.1-405b, llama-3-70B, llama-3-8B), Cohere models (command-r, command-r-plus), and many more open-source models.
How does Kolank optimize AI costs?
Kolank uses dynamic query routing to direct queries to the most cost-effective model capable of providing high-quality responses. It allows you to select a default routing model and automatically routes to less expensive models when appropriate, potentially saving up to 1,437,000 tokens monthly by avoiding overspending on basic queries.
What is the A2A protocol support in Kolank?
Kolank supports the Agent-to-Agent (A2A) protocol, which enables AI agents to communicate and collaborate with each other. This feature allows multiple AI agents to work together on complex tasks, exchanging information and coordinating actions seamlessly through the Kolank platform.
Does Kolank support streaming responses?
Yes, Kolank supports streaming responses through the stream parameter. When set to true, the API returns partial message deltas in real-time, enabling faster perceived response times and the ability to process content as it's being generated.
What happens if a model experiences downtime?
Kolank includes built-in fallbacks that automatically reroute queries when models face delays, downtime, or content moderation issues. This ensures reliable and efficient AI model usage with minimal disruption to your application.
How do I get a Kolank API key?
You can get a Kolank API key by creating a free account at kolank.com/keys. Once you have your API key, you can start making requests to the Kolank API using the provided authentication method with the Bearer token format.
What parameters does Kolank support for API requests?
Kolank supports all standard OpenAI-compatible parameters including messages, model, temperature, top_p, max_tokens, n, stop, stream, frequency_penalty, presence_penalty, logit_bias, logprobs, top_logprobs, seed, response_format (including JSON mode), tools (up to 128 functions), tool_choice, parallel_tool_calls, and user.
Can I compare models before choosing one?
Yes, Kolank allows you to compare models based on price per 1M tokens, latency, max output, context window size, and throughput across dozens of providers. The supported models table shows input/output pricing, context limits, and image input pricing for vision models to help you choose the best model for your needs.
