SRE Components Reference
The SmythOS Runtime Environment (SRE) provides a library of production-ready components.
Components are the building blocks of AI agents. Each encapsulates a reusable function, such as prompting an LLM, filtering JSON, or exposing an API endpoint.
How to use components
AI & LLM Components
Work with large language models and multimodal features.
GenAILLM— Unified interface for LLMs (OpenAI, Anthropic, Google, etc.)LLMAssistant— Multi-turn conversationVisionLLM— Image analysisMultimodalLLM— Text, image, and audioHuggingFace— Use Hugging Face-hosted modelsImageGenerator— Text-to-image
Example: prompt and stream responses
{`import { Agent, TLLMEvent } from '@smythos/sdk';
const agent = new Agent({ name: 'LLM Demo', model: 'gpt-4o' });
const llm = agent.llm.OpenAI('gpt-4o');
// One-shot prompt
const answer = await llm.prompt('Who wrote The Great Gatsby?');
console.log(answer);
// Stream tokens
const stream = await llm.prompt('Stream this response.').stream();
stream.on(TLLMEvent.Content, (chunk) => process.stdout.write(chunk));
`}
External Integrations
Connect to web data and APIs.
APICall— HTTP requests with headers and OAuthWebSearch— Real-time searchWebScrape— Extract site contentZapierAction— Trigger automationsMCPClient— Model Context Protocol client
When to use
Data Processing
Filter, clean, and prepare data.
Classifier— Categorize into classesJSONFilter— Extract or reshape JSONDataSourceIndexer— Index documentsDataSourceLookup— Retrieve from an indexDataSourceCleaner— Normalize inputs
Example: parse documents
{`import { Doc } from '@smythos/sdk';
// Auto-detect parser by file type
const parsed = await Doc.auto.parse('./files/report.pdf');
// Or specify explicitly
const pdf = await Doc.pdf.parse('./files/report.pdf');
const md = await Doc.md.parse('./files/notes.md');
`}
Logic & Control Flow
Shape how workflows run.
LogicAND,LogicOR,LogicXOR— Boolean logicLogicAtLeast,LogicAtMost— Threshold branchingForEach— Iterate over listsAsync,Await— Run steps in parallel and then join
Design tip
Storage & File Operations
Work with files and code execution.
FileStore— Read/write files (local or S3)Code— Execute inline codeServerlessCode— Run serverless functions
Example: local and S3 storage
{`import { Agent } from '@smythos/sdk';
const agent = new Agent({ name: 'Storage Demo', model: 'gpt-4o' });
// Local storage
const local = agent.storage.LocalStorage();
await local.write('hello.txt', 'Hello world');
const data = await local.read('hello.txt');
// S3 storage
const s3 = agent.storage.S3({
bucket: 'my-bucket',
region: 'us-east-1'
});
`}
Vector Databases
Embed, index, and search data.
- Pinecone
- Milvus
- RAMVec (in-memory)
Example: Pinecone search
{`import { Agent, Model } from '@smythos/sdk';
const agent = new Agent({ name: 'Vector Demo', model: 'gpt-4o' });
const pinecone = agent.vectorDB.Pinecone('my-namespace', {
indexName: 'my-index',
apiKey: process.env.PINECONE_API_KEY,
embeddings: Model.OpenAI('text-embedding-3-large'),
});
await pinecone.insertDoc('doc-1', 'Some text to index');
const results = await pinecone.search('Find similar content');
console.log(results);
`}
System Integration
Expose agents across protocols and services.
APIEndpoint— Create custom HTTP endpointsComputerUse— Automate system tasksGPTPlugin— OpenAI plugin format- MCP transport — Run agent as an MCP server
Example: run as MCP
{`import { Agent, MCPTransport } from '@smythos/sdk';
const agent = new Agent({ name: 'MCP Demo', model: 'gpt-4o' });
// STDIO
await agent.mcp(MCPTransport.STDIO);
// Or SSE
const url = await agent.mcp(MCPTransport.SSE, 3388);
console.log('MCP listening at', url);
`}
