LLM-IQ Agent API enables fast, code-free evaluation and comparison of top large language models like GPT-4, Claude 3, Gemini, Mistral, and Cohere. Designed for enterprise teams, it supports natural language queries to assess model performance across 25+ real-world use cases including reasoning, summarization, extraction, and query generation without the need for prompt engineering, dataset creation, or framework setup. With built-in performance benchmarking and domain-specific metrics, the API streamlines model selection and validation for AI, procurement, and compliance workflows.
The LLM IQ Agent API is a plug and play evaluation platform designed for enterprises seeking to benchmark and compare large language models (LLMs) such as GPT-4, Claude 3, Gemini, Mistral, and Cohere without the overhead of prompt engineering, dataset curation, or framework configuration.
Using natural language queries, teams can instantly access comprehensive benchmarking results across 25+ enterprise-grade evaluation domains, including reasoning, summarization, extraction, and query generation. The API supports questions like What is the best model for financial document summarization? or Compare Claude 3 and GPT-4 on reasoning tasks. Behind the scenes, it runs precision-tuned tests using multiple prompt variations and decoding strategies to simulate realistic workflows.
With actionable insights delivered through a professional-grade API, LLM-IQ Agent API enables intelligent decision-making at every stage of the GenAI lifecycle. Development teams can embed the API directly into inference workflows to power real-time model selection and dynamic prompt routing, automatically choosing the best-fit model for each user query. Procurement and vendor management functions gain standardized metrics for evaluating LLM providers, while engineering teams can offload the burden of framework development. For regulated industries, the API offers audit-ready evaluations aligned to compliance standards and domain-specific requirements. With LLM-IQ, enterprises gain a trusted layer of evaluation and transparency to support retrieval-augmented generation (RAG), multi-agent orchestration, and large-scale model deployment strategies.

You pay based on usage, measured by the number of successful API requests completed. This is a single, usage-based dimension. You are billed only for requests that finish successfully. Costs scale directly with how many successful API requests you make. There are no fixed tiers or seat counts in this pricing. As your request volume grows, your total charges grow in step. This structure lets your spending match your actual activity.
Top-of-mind questions for buyers
What counts as one successful API request for billing purposes?
A successful API request is a single completed call to the platform that finishes without error. Each completed call counts as one billable request. Failed or errored requests are not counted. This includes calls that trigger agent reasoning, data processing, or generated outputs across supported data types like text, tables, images, and PDFs.
Am I charged if an API request fails or does not complete?
No. You are billed only for requests that finish successfully. Failed or incomplete calls do not accrue charges. Your total cost tracks the count of successful requests. As your successful request volume rises, your charges rise in step. When request activity drops, charges drop with it.
Does this usage pricing include add-ons like domain-specific agents or custom applications?
The billed dimension covers successful API requests only. The platform offers add-ons such as pre-built customer-specific applications, domain-specific agents, and domain-specific models. Those add-ons are separate from the per-request charge shown here. Contact the vendor for details on how add-ons are provided and priced.

LLM-IQ Agent
The LLM-IQ Agent is an intelligent assistant that helps you select the optimal AI model for your use case. It analyzes comprehensive benchmark datasets and uses advanced querying capabilities to deliver personalized, data-driven model recommendations from a simple natural-language question.
Whether you're comparing model accuracy, identifying the best model for a specific task, or exploring the landscape of open- and closed-source models, the LLM-IQ Agent provides actionable insights without manual research.
How It Works
The agent operates over a structured dataset of model evaluations, parameters, metrics, and task-level results. It uses specialized internal tools, including:
Data extraction for retrieving model attributes
Filtering and ranking mechanisms for narrowing results
Aggregation for summarizing performance
Dataset metadata tools to provide context and coverage
When you submit a query, the agent parses your intent, selects the right tools, processes benchmark data, and returns clear recommendations with supporting evidence.
Key Benefits
Natural-language model selection
Data-driven recommendations grounded in benchmark results
Easy comparison of models across tasks and domains
Significant time savings through automated research
