PHP AI Tool Bridge is a flexible PHP framework designed to abstract away the complexity of interacting with various AI and large language model APIs. By defining a standard AiTool interface, it allows developers to switch between providers such as OpenAI, Azure OpenAI, and Hugging Face without modifying business logic. The library includes support for prompt templates, parameter configuration, streaming, function calls, request caching, and logging. It also features a tool execution pattern that enables chaining multiple AI tools, building conversational agents, and managing state through memory stores. PHP AI Tool Bridge accelerates the development of AI-powered features by reducing boilerplate and ensuring consistent API usage.

Stella Framework empowers developers to build robust AI agents that can maintain context, perform tool-assisted actions, and deliver dynamic conversational experiences. By abstracting the complexities of LLM integrations, Stella offers provider-agnostic adapters for OpenAI, Hugging Face, and self-hosted models. Agents can leverage customizable memory stores to recall user data and conversation history, and plugins enable interactions with external APIs, databases, or services. The built-in orchestration engine manages decision loops, while a concise DSL allows defining actions, tool calls, and response handling. Whether creating customer support bots, research assistants, or workflow automators, Stella provides a scalable foundation for deploying production-grade AI agents.
