artificial intelligence (ai) has made significant progress in developing language models capable of solving complex problems. However, applying these models to real-world scientific challenges remains difficult. Many ai agents struggle with tasks that require multiple cycles of observation, reasoning, and action. Additionally, existing models often lack the ability to effectively integrate tools or maintain consistency in multi-step reasoning. These questions are particularly pressing in scientific fields, where tasks demand precision, adaptability, and computational efficiency. Addressing these issues requires a flexible and practical framework for training and deploying language agents.
Introducing Aviary: an open source extensible gym
A team of researchers from FutureHouse Inc., the University of Rochester, and the Francis Crick Institute have introduced Aviary, an open-source gym for linguistic agents. Aviary addresses the limitations of existing frameworks by introducing language decision processes (LDPs), which model tasks as partially observable Markov decision processes based on natural language. This approach allows linguistic agents to effectively handle complex, multi-step reasoning tasks.
Aviary includes five environments, three of which are designed for advanced scientific tasks:
- Molecular cloning: Manipulation of DNA constructs using tools for sequence annotation and protocol planning.
- Quality control of scientific literature: Retrieve and analyze scientific literature to answer detailed research questions.
- Protein stability engineering: Propose protein mutations to improve stability with the help of computational and biochemical tools.
These tasks make Aviary a valuable platform for training and evaluating linguistic agents in real-world scenarios that require reasoning, tool integration, and iterative learning.
Technical information and benefits of the aviary
Aviary uses a stochastic computing graph framework to model language agents, enabling flexible and efficient optimization. Key features include:
- Expert Iteration (EI): A training method that iteratively refines agents using high-quality trajectories.
- Majority vote: A technique for improving accuracy by combining multiple inference results without excessive computational overhead.
- Tool integration: Integrated support for tools such as sequence annotators and literature retrieval systems, improving real-world applicability.
The researchers show that non-frontier open source models such as Llama-3.1-8B-Instruct can achieve comparable or better performance than frontier models (e.g. Claude 3.5 Sonnet) in these environments. Furthermore, these models operate at significantly lower inference costs, making them accessible for large-scale scientific applications.
Results and insights
Aviary-trained agents demonstrate impressive performance:
- In molecular cloning tasks, the Llama-3.1-8B-Instruct agent showed notable improvements in accuracy across EI and behavioral cloning, outperforming human experts on SeqQA benchmarks.
- In quality control tasks from the scientific literature, the same model achieved performance levels equal to or better than humans, while maintaining efficiency.
- Majority voting further improved accuracy, with SeqQA results reaching 89% after sampling multiple trajectories, outperforming the benchmarks of human and frontier models.
Conclusion
Aviary represents a thoughtful step forward in the development of ai language agents. By demonstrating that open source, borderless models can excel at scientific tasks, Aviary opens new possibilities for accessible and cost-effective ai research. Its open source design encourages collaboration, allowing researchers and developers to further refine and extend their applications.
With training tools and methods tailored to real-world challenges, Aviary sets a benchmark for how language agents can tackle complex tasks. It provides a compelling framework to advance ai-driven scientific exploration and practical problem solving.
