Limitations

While HyperFlow enables powerful self-improving agents, several technical and practical limitations exist in the current implementation.

Frozen Foundation Models

The most significant limitation is that the underlying Large Language Model (LLM) is frozen. - HyperFlow improves the Agent Logic (PHP code, prompts, and tools), but it cannot update the weights or training of the model itself. - All improvements are "external" to the model's core architecture.

Framework Immutability (Self-Update Paradox)

The Agent cannot evolve its own core classes! Because HyperFlow is often installed as a library (via composer), the core code for TaskAgent and MetaAgent lives in the system's vendor. - The MetaAgent cannot modify its own framework code or its class definitions. - Even in a local setup, the evolutionary loop targets a specific repo_path. If the agent's primary logic is outside that directory, it is impossible for the MetaAgent to reach out and update itself. - This is why the framework focuses on evolving prompts in external files and local domain logic?the core "Agent" infrastructure remains static and generic.

Fixed Task Distribution

Currently, the system optimizes for a fixed set of tasks provided by the user. Truly unbounded open-endedness requires a system that can also generate its own tasks and curriculum (co-evolution), which is a future research direction.

Static Outer Loop

While the agent can modify almost all of its own codebase (including its own MetaAgent logic), the outer evolutionary process is currently human-engineered: - Parent Selection: The logic for choosing which generations to branch from is fixed. - Evaluation Protocols: The way task scripts are run and scored is defined in the initial configuration.

Computational Cost

Evolutionary computation is resource-intensive. - Generations: Each experiment typically requires 50-200 iterations. - Costs: Depending on the Foundation Model (FM) used, a full run can be expensive in terms of API tokens.
