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, llmman, 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.

🚀 New: JevClassifier with typed Score classification

LLPhant now supports typed Jev classification with Noul, Choice, and the new Score rubric-based questions via JevClassifier. Returned answers now also expose Jev usage metadata via inputTokens and outputTokens fields. The same Jev integration can now be used to detect malicious prompt injections in QuestionAnswering through ClassifierPromptInjectionQueryTransformer.

To use JevClassifier, set your API key:

Then instantiate new JevClassifier(). If you prefer, you can also pass the key explicitly through new JevConfig(apiKey: '...').

See the full Jev API reference: https://docs.typesafe.ai/api and the LLPhant Jev guide in docs/jev-classifier.rst.
