Dynamo: Dynamic Skill-Tool Evolution for Vision-Language Agents

arXiv:2606.30185v1 Announce Type: new Abstract: Improving vision-language models (VLMs) on visual reasoning typically requires retraining or hand-designed prompts and tools. We present Dynamo, a training-free framework that adapts a frozen VLM without any weight updates. On a small labeled training subset, the agent inspects its own correct and incorrect attempts and evolves two complementary capabilities: reusable reasoning skills for cognitive bottlenecks, and executable visual tools for perceptual ones. Each generated tool is paired with a skill that specifies when to invoke it, and both ca

Why this matters
Why now

The proliferation of powerful vision-language models creates a bottleneck for effective task execution due to rigid prompting and the need for continuous retraining, making adaptive frameworks like Dynamo timely.

Why it’s important

This development represents a significant step towards more autonomous and adaptable AI systems, reducing the human effort in fine-tuning and expanding the capabilities of existing models.

What changes

Vision-language agents will be able to dynamically learn and evolve their own reasoning skills and visual tools, leading to greater efficiency and versatility without manual intervention or weight updates.

Second-order effects
Direct

AI agents become more capable of addressing diverse and novel visual reasoning tasks with reduced human oversight.

Second

The cost and complexity of deploying and maintaining highly effective vision-language agents decrease, accelerating their adoption across industries.

Third

The enhanced adaptability of AI agents could lead to new applications in unstructured environments currently too complex for static AI.
