The open-source TypeScript platform for AI agents and LLM based workflows
The Ancient Greek word sophía (σοφία) variously translates to "clever, skillful, intelligent, wise"
The Sophia platform provides a complete out-of-the box experience for building AI agents and LLM based workflows with TypeScript.
- Autonomous agents
- Software developer agents
- Code review agents
- Chat interface
- Chatbots (Slack integration provided)
- Functional callable tools (Filesystem, Jira, Slack, Perplexity, Google Cloud, Gitlab, GitHub and more)
- CLI and Web UI interface
- Run locally or deployed on the cloud with multi-user/SSO
- OpenTelemetry observability
Autonomous agents
- Reasoning/planning inspired from Google's Self-Discover and other papers
- Memory and function call history for complex workflows
- Iterative planning with hierarchical task decomposition
- Sandboxed execution of generated code for multi-step function calling and logic
- LLM function schemas auto-generated from source code
- Human-in-the-loop for budget control, agent initiated questions and error handling
Software developer agents
- Code Editing Agent:
- Auto-detection of project initialization, compile, test and lint
- Task file selection agent
- Code editing loop with compile, lint, test, fix (editing delegates to Aider)
- Compile error analyser can search online, add additional files and packages
- Review the changes with an additional code editing loop if required.
- Software Engineer Agent (For issue to Pull Request workflow):
- Find the appropriate repository from GitLab/GitHub
- Clone and create branch
- Call the Code Editing Agent
- Create merge request
- Code review agents
- Query repository agent
Chatbots
- Slack chatbot
Flexible run/deploy options
- CLI interface
- Web interface
- Scale-to-zero deployment on Firestore & Cloud Run
- Multi-user SSO enterprise deployment (with Google Cloud IAP)
LLM support
OpenAI, Anthropic (native & Vertex), Gemini, Groq, Fireworks, Together.ai, DeepSeek, Ollama, Cerebras
-
Filesystem, Jira, Slack, Perplexity, Gitlab and more
-
Observability with OpenTelemetry tracing
-
Code Review agent:
- Configurable code review guidelines
- Posts comments on GitLab merge requests at the appropriate line with suggested changes
UI Examples
New Agent
Sample trace
Human in the loop notification
Agent requested feedback
List agents
Code review configuration

Sophia vs LangChain
Sophia doesn't use LangChain, for many reasons that you can read online
Let's compare the LangChain document example for Multiple Chains to the equivalent Sophia implementation.
LangChain
import { PromptTemplate } from "@langchain/core/prompts";
import { RunnableSequence } from "@langchain/core/runnables";
import { StringOutputParser } from "@langchain/core/output_parsers";
import { ChatAnthropic } from "@langchain/anthropic";
const prompt1 = PromptTemplate.fromTemplate(
`What is the city {person} is from? Only respond with the name of the city.`
);
const prompt2 = PromptTemplate.fromTemplate(
`What country is the city {city} in? Respond in {language}.`
);
const model = new ChatAnthropic({});
const chain = prompt1.pipe(model).pipe(new StringOutputParser());
const combinedChain = RunnableSequence.from([
{
city: chain,
language: (input) => input.language,
},
prompt2,
model,
new StringOutputParser(),
]);
const result = await combinedChain.invoke({
person: "Obama",
language: "German",
});
console.log(result);
Sophia
import { llms } from '#agent/context'
import { anthropicLLMs } from '#llms/anthropic'
const prompt1 = (person: string) => `What is the city ${person} is from? Only respond with the name of the city.`;
const prompt2 = (city: string, language: string) => `What country is the city ${city} in? Respond in ${language}.`;
runAgentWorkflow({ llms: anthropicLLMs() }, async () => {
const city = await llms().easy.generateText(prompt1('Obama'));
const result = await llms().easy.generateText(prompt2(city, 'German'));
console.log(result);
});
The Sophia code also has the advantage of static typing with the prompt arguments, enabling you to refactor with ease. Using simple control flow allows easy debugging with breakpoints/logging.
To run a fully autonomous agent:
startAgent({
agentName: 'Create ollama',
initialPrompt: 'Research how to use ollama using node.js and create a new implementation under the llm folder. Look at a couple of the other files in that folder for the style which must be followed',
functions: [FileSystem, Perplexity, CodeEditinAgent],
llms,
});
Automated LLM function schemas
LLM function calling schema are automatically generated by having the @func
decorator on class methods, avoiding the
definition duplication using zod or JSON.
@funcClass(__filename)
export class Jira {
instance: AxiosInstance | undefined;
/**
* Gets the description of a JIRA issue
* @param {string} issueId - the issue id (e.g. XYZ-123)
* @returns {Promise<string>} the issue description
*/
@func()
async getJiraDescription(issueId: string): Promise<string> {
if (!issueId) throw new Error('issueId is required');
const response = await this.axios().get(`issue/${issueId}`);
return response.data.fields.description;
}
}
