Usage
Chain Service
Use the Chain
service to leverage GPT:
use PhpLlm\LlmChain\Chat; final readonly class MyService { public function __construct( private Chain $chain, ) { } public function submit(string $message): string { $messages = new MessageBag( Message::forSystem('Speak like a pirate.'), Message::ofUser($message), ); return $this->chain->call($messages); } }
Register Tools
To use existing tools, you can register them as a service:
services: _defaults: autowire: true autoconfigure: true PhpLlm\LlmChain\ToolBox\Tool\Clock: ~ PhpLlm\LlmChain\ToolBox\Tool\OpenMeteo: ~ PhpLlm\LlmChain\ToolBox\Tool\SerpApi: $apiKey: '%env(SERP_API_KEY)%' PhpLlm\LlmChain\ToolBox\Tool\SimilaritySearch: ~ PhpLlm\LlmChain\ToolBox\Tool\Wikipedia: ~ PhpLlm\LlmChain\ToolBox\Tool\YouTubeTranscriber: ~
Custom tools can be registered by using the #[AsTool]
attribute:
use PhpLlm\LlmChain\ToolBox\AsTool; #[AsTool('company_name', 'Provides the name of your company')] final class CompanyName { public function __invoke(): string { return 'ACME Corp.' } }
Profiler
The profiler panel provides insights into the chain's execution:
