Caesar
Caesar is an autonomous AI research agent that navigates the web, builds a knowledge graph, and synthesizes novel, grounded answers. It is designed for open-ended, creative, cross-disciplinary research where simple retrieval is insufficient. It is for developers and researchers who need deep, original insights rather than quick factual lookups.
✨ Key features
- Persistent knowledge graph built during exploration
- Adversarial refinement over its own drafts
- Serialized graph and JSON run log you keep
- Runs on your own keys and hardware
- Domain-specific role adaptation
- Knowledge-guided exploration policy
🎯 Use cases
- Hypothesis generation across domains
- Literature synthesis with graph-grounded review
- arXiv citation-graph review
- Competitive intelligence mapping
- Counterfactual and meta-creative reasoning
📦 Installation
🧰 Requirements: Python 3.10-3.13, an OPENAI_API_KEY (or Anthropic/Google/Brave keys for additional models/search), and internet access.
pip install caesar-agent
export OPENAI_API_KEY=your_key
From source:
git clone https://github.com/jasonzliang/caesar-agent.git
cd caesar-agent && pip install -e .
export OPENAI_API_KEY=your_key
🚀 Usage
caesar regular -q "your research question"
For a browser GUI:
cd web_server && ./launch.sh
# then open http://localhost:3000
⚠️ Good to know
Caesar is a research prototype, not a GA product; it is not suited for quick factual lookups or latency-sensitive applications, and it requires API keys (no zero-setup option).
❓ FAQ
Do I need GPUs?
No. Caesar uses hosted LLM APIs (OpenAI, Anthropic) and a local ChromaDB for vector storage; it runs on a laptop.
Which models are supported?
OpenAI (GPT-5 family, o-series), Anthropic (Claude 4.5/4.6), Google (Gemini 3.x), and any OpenAI-compatible endpoint, configurable per subsystem via YAML.
How much does a typical run cost?
A 5-iteration exploration with GPT-5.4-mini costs roughly $0.30 and takes 10 minutes; a 250-iteration deep run with the regular preset is typically $5–$10.
Can I reproduce the benchmarks?
Yes. Configs, judge rubrics, and evaluation scripts are in caesar/config/ and caesar/analysis/.
