Inherent's Faraday Agent Outperforms Anthropic and OpenAI at Research Replication — on 27B Parameters
Inherent's Faraday agent replicated scientific findings more effectively than frontier models from Anthropic and OpenAI while running on a 27-billion-parameter Qwen 3.6 base.
London-based startup Inherent, founded by Google DeepMind alumni, has released details on its AI agent Faraday following a $50 million seed round. The system successfully reproduced the findings of published scientific papers without prior knowledge of the results, a task where it outperformed Anthropic's Claude Opus 4.8 and OpenAI's GPT-5.5. Unlike these competitors, which operate at frontier scale, Faraday achieves these results using a significantly smaller underlying model: Qwen 3.6 with just 27 billion parameters. This parameter count serves as a proxy for model size and training costs, highlighting a divergence in strategy between Inherent and better-funded rivals who have yet to demonstrate concrete outputs.
The development approach prioritizes reinforcement learning over static rule sets to instill what cofounder Edward Hughes terms "research taste." Rather than training primarily on the study of scientific methodology, the team rewards the agent for successful experimental outcomes, aiming to generalize this capability toward discovering new knowledge rather than merely verifying existing results. To support this workflow without reinventing infrastructure, Inherent opted against building a proprietary coding tool; instead, Faraday leverages OpenAI's GPT-5.5 Codex for implementation tasks. This architectural choice mirrors human scientific collaboration, where researchers utilize established software tools to execute experiments designed through independent reasoning.
Operationally, Inherent maintains a fully in-person team of twelve employees in King's Cross, London, with plans to expand headcount to between 20 and 25 by year-end. The company's growth strategy intersects with ongoing debates regarding UK employment practices; Hughes has publicly advocated for ending "garden leave" restrictions that delay departing employees from joining competitors, a constraint he cites as a personal hurdle during formation. While the immediate benchmark focuses on paper replication—a standard exercise for PhD students—the underlying objective remains the construction of an autonomous AI scientist capable of contributing across multiple scientific fields through curious, self-directed experimentation.
