Keywords AI

Keywords AI is an all-in-one developer platform, backed by Y Combinator, specifically engineered for the entire lifecycle of Large Language Model (LLM) applications. It serves as the #1 LLM monitoring platform for AI startups, providing a streamlined and powerful toolkit to debug, monitor, and scale AI features with unprecedented speed and reliability.

The platform is built with developers in mind, offering a unified interface that abstracts away the complexities of interacting with various LLM providers. Whether you're using models from OpenAI, Anthropic, or open-source alternatives like Llama, Keywords AI provides a single, consistent API endpoint. This not only saves countless hours of building custom clients but also enhances scalability by bypassing rate limits and handling hundreds of concurrent calls with no latency impact.

How to use Keywords AI

Getting started with Keywords AI is designed to be incredibly simple and non-disruptive to existing codebases. The integration process is famously easy, often requiring just a two-line change in your code. For developers already using the OpenAI SDK, it's as simple as changing the `base_url` to point to the Keywords AI API endpoint and using your Keywords AI API key. This seamless integration means you can start logging, monitoring, and analyzing your LLM traffic in under two minutes without rewriting your application logic.

Once integrated, you can leverage the platform's full suite of tools through its intuitive web interface, which is designed for keyboard-driven navigation for maximum efficiency. You can manage prompts, run experiments, set up evaluations, and configure infrastructure settings like load balancing and caching directly from the dashboard.

Core Features of Keywords AI

• Unified LLM Gateway: A single API to access over 200 LLMs, embedding models, and audio models. It includes a powerful proxy, load balancing with custom weights, model fallbacks for high availability, and customizable retries.
• Comprehensive Observability (Signals): A unified view combining logs, traces, and threads to provide a complete picture of your LLM workflows. It supports multimodal monitoring for text, images, and audio.
• Advanced Monitoring & Dashboards: Pre-built, customizable dashboards with real-time metrics on cost, latency, token usage, and error rates. Visualize data with line or bar charts at a minute-level granularity.
• Testing & Evaluation Suite: Run experiments with prompts and models in a spreadsheet-style interface (Lab & Testsets). Conduct A/B tests, manage prompt versions, and use LLM-as-a-judge, human, or code-based evaluations.
• Optimization & Cost Control: Reduce latency and costs with intelligent LLM caching for both text and image requests. Set monthly budgets, usage limits, and alerts to manage spending effectively.
• Data Management for Fine-Tuning: Easily collect and export production data into datasets for fine-tuning models or generating synthetic data.
• Seamless Integrations: Native support for popular frameworks and tools like OpenAI SDK, LangChain, LlamaIndex, Vercel AI SDK, BAML, and PostHog.

Use Cases for Keywords AI

Keywords AI is versatile and caters to various roles within an AI-driven team. For AI startups, it accelerates the journey from MVP to a production-ready application by providing robust, scalable infrastructure out-of-the-box. Developers can leverage the unified API and deep observability to debug complex issues in chains and agents, significantly reducing development time. Product Managers can use the detailed analytics and user session logs to understand user behavior, monitor performance, and make data-driven decisions to improve the user experience. ML Engineers can systematically run experiments, evaluate model performance, and use the data collection tools to fine-tune models for optimal cost and performance.

Advantages of Keywords AI

The primary advantage of Keywords AI is its exceptional developer experience (DX) and simplicity. The platform consolidates the entire LLM development stack into one cohesive unit, eliminating the need for multiple disparate tools. Its ability to scale effortlessly, combined with powerful cost-management features, makes it a highly efficient solution. The deep, actionable insights provided by its monitoring and evaluation tools empower teams to build more reliable, performant, and cost-effective AI applications, giving them a competitive edge.

Pricing and Plans

Keywords AI operates on a freemium model. It offers a generous free tier that allows developers and small teams to get started and explore the core features of the platform without any initial investment. As applications scale and require more advanced capabilities, higher request volumes, or team collaboration features, users can upgrade to paid plans.
