Nous Research Launches Hermes 4 AI Model, Challenging ChatGPT
Nous Research Unveils Hermes 4: A Powerful Open-Source AI Challenger
Nous Research, a relatively unknown artificial intelligence startup, has made waves in the tech industry with the release of its Hermes 4 large language model series. The company claims this new model not only matches but surpasses current commercial systems in certain benchmarks while offering users greater freedom and control.

Breaking Free from Content Restrictions
Unlike mainstream AI models from OpenAI, Google, or Anthropic, Hermes 4 operates without the typical safety protections found in commercial systems. This bold approach represents a growing divide between open-source AI advocates and large technology companies regarding how artificial intelligence should be developed and regulated.
"Hermes 4 is built upon a user-centric model," Nous Research announced on social media. "We've focused on enhancing creativity and entertainment value while maintaining strong performance in mathematics, programming, and reasoning tasks."
Technical Innovations Powering Hermes 4
The model introduces several groundbreaking features:
- Hybrid Reasoning Mode: Users can choose between quick responses or detailed step-by-step thinking processes. When enabled, the model displays its reasoning within special tags before providing final answers.
- Advanced Training Systems: Nous Research developed two proprietary systems for training:
- DataForge: Generates synthetic data through graphics, transforming simple pre-training data into complex instruction-following instances.
- Atropos: An open-source reinforcement learning framework with hundreds of specialized training environments for skill-specific practice.
Impressive Benchmark Performance
In recent testing:
- The largest Hermes 4 version (405 billion parameters) achieved 96.3% on the MATH-500 benchmark
- Scored 81.9% in the AIME'24 math competition - results comparable to expensive commercial systems
The model particularly excels in mathematical applications while maintaining strong performance across other domains.
The Open-Source Movement Gains Momentum
The release comes at a pivotal moment for AI development as open-source models increasingly challenge commercial offerings. Small startups like Nous Research demonstrate they can compete with tech giants through innovation and specialized approaches.
"Hermes 4 represents more than just technological achievement," the company stated. "It's about rethinking who controls artificial intelligence's future and prioritizing user transparency."
