Klu

Launched in 2022, UK- and US-based firm Klu is an all-in-one large language model (LLM) application platform for building, evaluating, and optimizing AI applications.

Klu offers a suite of integrated products that facilitates companies to optimize LLM-powered features built on LLMs like GPT-4. These include Klu Studio for quick prototyping and iteration, Klu Engine for accessing leading AI models like GPT-4 and Llama 2, Klu Eval for running AI-powered evals on new iterations, and Klu Optimise for leveraging real-world usage data to improve the outputs with fine-tuning continuously.

Klu supports integrations with all major LLM providers including OpenAI, Azure, GCP Vertex, and AWS Bedrock. It also offers seamless connections to data sources, including 24 file types. Customers have the ability to integrate their Klu-created LLM apps with various software solutions including CRMs, ticketing systems, and databases, including Salesforce, Atlassian, Supabase, Asana, Intercom, Zendesk, Slack, Notion, and Google. Klu customers also receive continuous observability insights and evaluation of prompt changes as AI engineers update features and prompts.

It claims that its solutions enable any business to deploy, observe, and optimize an advanced LLM-enabled feature in under 10 minutes, a process that would normally take months or quarters when building an internal ops system.

Klu follows a subscription model and provides its offerings at different prices for its users based on their requirements. Users can choose monthly or annual plans and all plans include free generation with GPT-3.5 turbo and GPT-4. The firm also offers a free tier for hobby projects.
