Silicon Valley company Diffbot has released a new AI model that combines Meta’s LLama 3.3 with their trillion-fact Knowledge Graph to improve factual accuracy in AI responses.
The innovation: Diffbot’s new AI model introduces Graph Retrieval-Augmented Generation (GraphRAG), which queries a constantly updated knowledge database instead of relying solely on pre-trained data.
- The system leverages Diffbot’s Knowledge Graph, an automated database that has been crawling the web since 2016
- The Knowledge Graph refreshes every 4-5 days with millions of new facts
- The model can search for real-time information and cite original sources when responding to queries
Technical implementation: The model represents a significant departure from traditional large language models by separating reasoning capabilities from knowledge storage.
- CEO Mike Tung believes general purpose reasoning can be distilled to about 1 billion parameters
- The system prioritizes tool usage and external knowledge querying over storing information within the model
- The approach allows for real-time fact verification and updates, unlike static training data used in conventional AI models
Performance metrics: Diffbot’s solution has demonstrated strong results in industry-standard testing environments.
- Achieved 81% accuracy on Google’s FreshQA benchmark for real-time factual knowledge, outperforming ChatGPT and Gemini
- Scored 70.36% on MMLU-Pro, a challenging test of academic knowledge
- Real-world applications include data services for major companies like Cisco, DuckDuckGo, and Snapchat
Technical specifications and accessibility: The model is being released as open-source software with flexible deployment options.
- Available immediately through GitHub with a public demo at diffy.chat
- 8 billion parameter version runs on a single Nvidia A100 GPU
- Full 70 billion parameter version requires two H100 GPUs
- Organizations can run the model locally, addressing data privacy concerns
Market implications: Diffbot’s approach challenges the industry’s focus on increasingly larger AI models.
- Addresses growing concerns about AI hallucinations and false information generation
- Offers enterprises a more accurate and auditable solution for sensitive data handling
- Provides an alternative to the “bigger is better” paradigm in AI development
Looking beyond size: The sustainable development of AI technology may depend more on efficient knowledge organization and access than on expanding model parameters.
- The approach emphasizes data provenance and knowledge modification capabilities
- Facts can be updated and verified in real-time through the Knowledge Graph
- This methodology could influence how future AI systems are designed and deployed
Future implications: While Diffbot’s innovation presents a promising direction for AI development, its ability to reshape industry practices will depend on widespread adoption and real-world performance at scale.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
