Kosmos now supports multiple LLM providers, giving you flexibility in cost, privacy, and model selection:
| Provider | Type | Example Models | Privacy | Cost |
|---|---|---|---|---|
| Anthropic | Cloud | Claude 3.5 Sonnet, Opus, Haiku | Cloud | $$ |
| OpenAI | Cloud | GPT-4 Turbo, GPT-4, GPT-3.5, O1 | Cloud | $$$ |

Switch providers with zero code changes - just update your .env file:
# Use OpenAI instead of Anthropic
LLM_PROVIDER=openai
OPENAI_API_KEY=sk-...
OPENAI_MODEL=gpt-4-turbo
# Or run completely local with Ollama (free)
LLM_PROVIDER=openai
OPENAI_BASE_URL=http://localhost:11434/v1
OPENAI_MODEL=llama3.1:70bBenefits:
- Cost Flexibility: Mix expensive/cheap models or use free local models
- Privacy Options: Run entirely locally for sensitive research
- Provider Independence: Switch based on availability, pricing, performance
- Redundancy: Mitigate rate limits and service disruptions
- Access Specialized Models: Domain-specific or fine-tuned models
Provider Setup Guide - Detailed instructions for all supported providers
Kosmos maintains a persistent knowledge graph that automatically captures your entire research journey. Every hypothesis, experiment, and finding is stored in a connected graph that survives between sessions.
What Gets Captured:
- Research questions and hypotheses
- Experiment protocols and results
- Relationships (SPAWNED_BY, TESTS, SUPPORTS, REFUTES, REFINED_FROM)
- Rich provenance (who, when, why, confidence scores, p-values)
Key Benefits:
- Knowledge Accumulation: Build expertise over weeks/months instead of starting fresh
- Research Provenance: Track how hypotheses evolved and what evidence supports them
- Collaboration: Export and share knowledge graphs with colleagues
- Version Control: Save snapshots at research milestones
- Data Safety: Regular exports protect against data loss
CLI Commands:
# View your accumulated knowledge
kosmos graph --stats
# Example output:
# 📊 Knowledge Graph Statistics
#
# Entities: 127
# Relationships: 243
#
# Entity Types:
# Hypothesis: 45
# ExperimentProtocol: 28
# ExperimentResult: 23
# Export for backup or sharing
kosmos graph --export my_research.json
# Restore from backup
kosmos graph --import my_research.jsonAutomatic Persistence:
No manual action required! When you run research:
kosmos research "How do transformers learn long-range dependencies?"Kosmos automatically persists:
- ResearchQuestion entity
- Generated Hypothesis entities + SPAWNED_BY relationships
- ExperimentProtocol entities + TESTS relationships
- ExperimentResult entities + SUPPORTS/REFUTES relationships with statistical metadata
- Refined hypotheses + REFINED_FROM relationships
Setup:
# Using Docker (recommended)
docker-compose up -d neo4j
# Or manual Neo4j installation
# Ubuntu: sudo apt install neo4j
# macOS: brew install neo4j
# Configure in .env
NEO4J_URI=bolt://localhost:7687
NEO4J_PASSWORD=kosmos-password
WORLD_MODEL_ENABLED=trueWorks Without Neo4j: Kosmos continues working normally if Neo4j is unavailable (graceful degradation). Graph features are optional enhancements.

Kosmos includes a sophisticated multi-tier caching system that reduces API costs by 30-40%:
# View cache performance
kosmos cache --stats
# Example output:
# Overall Cache Performance:
# Total Requests: 500
# Cache Hits: 175 (35%)
# Estimated Cost Savings: $15.75Cache Types:
- LLM Response Cache: API response caching (25-35% hit rate with Anthropic prompt caching)
- Experiment Cache: Computational result caching (40-50% hit rate)
- Embedding Cache: Vector embedding caching (in-memory, fast)
- General Cache: Miscellaneous data caching
Benefits:
- Reduced API costs (30%+ savings)
- Faster response times (90%+ faster on cache hits)
- Improved reliability (cached responses always available)
- Lower environmental impact
Note: Prompt caching with significant cost savings is currently available when using Anthropic Claude. OpenAI and local providers use in-memory response caching only.
When using Anthropic as your LLM provider, Kosmos intelligently selects between Claude models based on task complexity:
- Claude Sonnet 4.5: Complex reasoning, hypothesis generation, analysis
- Claude Haiku 4: Simple tasks, data extraction, formatting
This reduces costs by 15-20% while maintaining quality.
Note: This feature is specific to Anthropic Claude. OpenAI and other providers use a single configured model.
Typical research run characteristics (using Anthropic Claude):
- Duration: 30 minutes to 2 hours
- Iterations: 5-15 iterations
- API Calls: 50-200 calls
- Cost: $5-$50 with caching (without caching: $8-$75) [Anthropic pricing]
- Cache Hit Rate: 30-40% on subsequent runs [Anthropic prompt caching]
Note: Costs vary by provider. OpenAI pricing may differ. Local models (Ollama/LM Studio) have $0 API costs.
- Python 3.11 or 3.12
- LLM Provider - Choose one:
- Anthropic Claude (default) - API key (pay-per-use) or Claude Code CLI (Max subscription)
- OpenAI GPT - API key for GPT models
- Ollama - Free local models (no API key needed)
- Other providers - See Provider Setup Guide
