Tesla Multi-Agent: A Local Multi-Model Research Agent System Based on LangGraph

Tesla is a fully locally-run multi-agent research system built on LangGraph, adopting a role-based model routing architecture. It supports anti-detection web search, RAG, and Telegram interaction. This article analyzes its multi-model orchestration, intelligent web search, and RAM-aware design. Its core values lie in privacy protection and cost reduction through local operation, as well as enhanced ability to handle complex research tasks via specialized model division.

Single large language models struggle with complex research tasks (intent understanding, planning, search, reasoning, coding, etc.), as each subtask has different requirements for model capabilities (planning needs logic, search needs tool calling, coding needs code understanding). Tesla's solution: Build a stateful multi-agent workflow using LangGraph, where subtasks are handled by the most suitable specialized models. Models collaborate via serialized context and run fully locally (models loaded via Ollama).

Core Architecture Based on LangGraph

Workflow: Request Router → Orchestrate → [Research | Coding | Reasoning | Briefing] → Orchestrator(Progress) → ... → Synthesize → END

Key Design

1. Specialized Division of Labor: Orchestrator (coordinates task intent, planning, routing), Researcher (web search and reasoning), Coder (code generation and debugging);
2. State Persistence and RAM Awareness: Use LangGraph state machine; when switching models, unload current model, serialize context, load new model and restore, enabling multi-model operation on a single machine;
3. Iterative Refinement: Orchestrator evaluates progress, decides whether to continue calling experts or enter the synthesis phase.

Layer 1: Chrome CDP (Recommended)

• Real user profile: Bypass detection using real IP, cookies, and browsing history;
• Human behavior simulation: Inject red cursor, Bezier curve mouse movement, smooth scrolling;
• Visual feedback: Users can see the Agent's operation process.

Layer 2: Camoufox + Crawl4AI (Backup)

Camoufox (Firefox privacy browser) + Crawl4AI (structured content extraction), supporting stdio/HTTP MCP transmission modes.

Workspace Customization

Customize role system prompts via Markdown files (YAML frontmatter format) in the workspace/ directory, supporting version control, non-technical personnel editing, rapid iteration, and specifying model providers via environment variables.

Telegram Bot Interaction

• Cross-platform asynchronous support;
• Single instance locking to prevent message confusion;
• Exponential backoff retries to handle network fluctuations;
• Send progress updates at key nodes.

Deployment Methods

1. Local Conda: Clone repository → create environment → activate;
2. Docker Compose (Recommended): Copy .env.example → fill in Token/ID → start service;
3. Health check: Pre-launch script checks environment variables, model configuration, and Ollama availability.

Airflow Scheduling

Integrate Apache Airflow to implement periodic tasks: daily news summaries, weekly industry reports, competitor monitoring, etc.

Technical Highlights

1. LangGraph state machine ensures execution of complex workflows;
2. Role-based model routing improves performance;
3. Anti-detection search breaks through information acquisition bottlenecks;
4. RAM-aware design enables multi-model operation on limited hardware;
5. Markdown prompts lower customization thresholds.

Future Trends

Tesla represents the local-first Agent trend: no need for cloud APIs, privacy protection + low cost, complementary to cloud-based Agents, and will enrich the AI application ecosystem.
