Cyberian (Agent-Based)

Setup

pip install deep-research-client[cyberian]

Cyberian uses local AI agents (Claude, Aider, etc.) - no separate API key needed.

Parameters

from deep_research_client.provider_params import CyberianParams

params = CyberianParams(
    agent_type="claude",       # claude, aider, cursor, goose
    workflow_file=None,        # Custom workflow file
    port=3284,                 # agentapi server port
    skip_permissions=True,     # Skip permission checks
    sources="academic papers"  # Source guidance
)

Characteristics

• Cost: Variable (depends on agent)
• Speed: 10-30+ minutes
• Capabilities: Iterative research, citation management, comprehensive synthesis

When to Use

• Comprehensive literature reviews
• Deep technical research
• Multi-source citation management

Provider Detection

Providers are auto-detected based on environment variables:

# Check available providers
deep-research-client providers

Adding Custom Providers

Create a new provider in src/deep_research_client/providers/:

from . import ResearchProvider
from ..models import ResearchResult

class NewProvider(ResearchProvider):
    async def research(self, query: str) -> ResearchResult:
        # Implementation
        return ResearchResult(...)
