Nous Research Deep Dive: A Decentralized AI Lab That Paradigm Invested in at a $1B Valuation, Comprehensive Breakdown of the Hermes Model and the Psyche Network

Nous Research is an open-source AI lab founded by AI researchers, known for its Hermes series of models. In April 2025, it raised a $50 million A round led by the crypto VC Paradigm at a valuation of $1 billion. Its distinctive approach is that the founding team is crypto native, but it chose to prove itself first with AI research results, and then to integrate the blockchain—rather than the other way around.

Founding team: from the open-source community to a $1 billion valuation

Nous Research was founded in 2022. Its core team includes CEO Jeffrey Quesnelle, co-founder Karan Malhotra, the head of post-training and co-founder Teknium, and Diederik Kingma—an Adam optimizer co-inventor. Their contributions are textbook-caliber results in the field of deep learning. Teknium is also one of the most active contributors in the open-source LLM fine-tuning space, widely known under a “handle.”

Nous began as a community of high-signal AI researchers and developers focused on unlocking the maximum potential of open-source models, and only later formally became a company. With a team size of 20, it is far smaller than OpenAI or Anthropic, yet it continues to turn in impressive results in the open-source model space. According to Teknium’s statement in a Delphi Digital AMA, Nous’s Hermes 4 model scores about 60 points higher than Meta’s own Llama instruct version on the MATH benchmark, and is 21 points higher on MMLU-Pro.

Hermes models: 90% synthetic data, 60% non-refusal rate

Nous’s best-known product is the Hermes series of models. Unlike commercial models such as ChatGPT, Hermes’s design philosophy is to reduce unnecessary refusals. Teknium points out that Hermes 4 reaches a 60% non-refusal rate, while the open-source version of ChatGPT is only 5%. He describes the excessive scrutiny of mainstream models as “mode collapse of the world.”

In terms of its data strategy, more than 90% of Nous’s training data is synthetic data, coming from its own DataForge synthetic data pipeline and the Atropos reinforcement learning environment (more than 1,200 tasks). This approach allows a small team to compete with large companies on data quality.

The Hermes model is also the foundation for Hermes Agent—a framework for open-source AI agents that supports multiple platforms, persistent memory, and self-learning.

Psyche Network: decentralized AI training on Solana

The core overlap between Nous Research and crypto is Psyche Network— a decentralized AI training network built on the Solana blockchain. Psyche aims to enable globally idle GPU compute power to collaboratively train large language models, incentivizing participants to contribute compute power through a token mechanism.

Technically, Psyche is based on DisTrO (Distributed Training Over-the-Internet, a distributed training optimizer) that Nous developed in-house, which reduces the amount of data transferred during training by several orders of magnitude, making cross-region distributed training feasible in practice. In December 2024, the team publicly streamed a demonstration of pretraining a 15 billion-parameter language model using a distributed approach to show the technical feasibility.

In an interview with Cointelegraph, co-founder Malhotra admitted that the AI community generally holds skepticism toward crypto, often believing it is mostly “grift.” But he emphasized that Nous’s path is “to prove AI research capability first, and then integrate the blockchain,” rather than wrapping nonexistent technology in crypto concepts.

Why Paradigm is betting: the open vs. closed AI battle

Paradigm partner Arjun Balaji told Fortune: “This kind of open, community-driven approach forms a stark contrast to closed, centralized mainstream AI labs.”

Paradigm’s $50 million investment is based on a $1 billion token valuation, rather than traditional equity valuation. Previously, Distributed Global, North Island Ventures, and Delphi Digital had already invested $20 million in the seed round.

No token has been issued yet, and “NOUS” on DEXs is unofficial

As of April 2026, Nous Research’s official token has not been formally issued. Although a token trading pair using the name “NOUS” has appeared on decentralized exchanges on the Solana chain, these are not tokens officially issued by Nous Research. Investors should pay special attention to verify and avoid purchasing unofficial tokens that could result in losses.

In addition, there is another project with a similar name in the market: Nosana ($NOS). It is also an AI compute project on Solana, but it is completely unrelated to Nous Research.

From Harness to decentralized training: Nous’s complete layout

Looking across Nous Research’s product line, you can see a complete setup from models to infrastructure: the Hermes model provides open-source LLMs, Hermes Agent provides an AI agent framework, and Psyche Network provides decentralized training infrastructure. The three are connected via the Solana blockchain, forming an open ecosystem that goes from training to deployment to applications.

Amid the trend of AI competition increasingly concentrating among a small number of giants, Nous Research represents a different path—using open-source research to build technical credibility, and using blockchain incentive mechanisms to expand the sources of compute power, aiming to show that decentralized AI training is not just an ideal, but a viable alternative.
