LLPhant - The PHP library for Gen AI and Vector Databases

We designed this framework to be as simple as possible, while still providing you with the tools you need to build powerful apps. It is compatible with Symfony and Laravel.

We are working to expand the support of different LLMs. Right now, we are supporting OpenAI, Anthropic, Mistral, Ollama, LM Studio, Atlas Cloud and services compatible with the OpenAI API such as LocalAI. Ollama that can be used to run LLM locally such as Llama 2.

Atlas Cloud

LLPhant's AtlasCloudConfig targets the OpenAI-compatible Atlas Cloud endpoint at https://api.atlascloud.ai/v1 and now defaults to the validated chat model qwen/qwen3.5-flash.

The configuration also accepts any Atlas model slug exposed by your account via the optional ATLASCLOUD_MODEL environment variable. Examples from the current public Text model list include:

• qwen/qwen3.5-flash
• qwen/qwen3.6-plus
• deepseek-ai/deepseek-v4-flash
• deepseek-ai/deepseek-v4-pro
• google/gemini-3.5-flash
• zai-org/glm-4.7

We want to thank few amazing projects that we use here or inspired us:

• the learnings from using LangChain and LLamaIndex
