DARWIN: Dynamic Agentically Rewriting Self-Improving Network
DARWIN is an evolutionary GPT model, utilizing a genetic-algorithm like optimization structure with several independent GPT agents being trained individually using unique training code. Each iteration, the GPT models are prompted to modify the training code of one another in an attempt to improve their performance in a mutation-like manner, and the best GPT agents are then benchmarked and selected for the next iteration by genetic algorithm. For demonstration purposes and due to budget and time constraints, OpenAI API is used to prompt training code improvements and the nanoGPT framework is used as the training code. DARWIN also utilizes persistent JSON-based memory files to track previous reasoning and changes to code to correlate with improvement to model performance. and a bidirectional interface for HITL intervention allowing the model to request upgrades such as additional datasets, training scripts, and restructuring of file hierarchies. In experiments, DARWIN achieved a 1.26 percent improvement in model FLOPS utilization (MFU) and a 2.07 percent improvement to perplexity in 5 iterations of training over baseline configurations, demonstrating promising capabilities as a foundation for scaling evolutionary GPT training.

DARWIN pioneers an evolutionary GPT model, leveraging genetic algorithms for autonomous self-improvement through code modification. It represents a significant step towards AGI by allowing models to iteratively enhance their own training procedures, moving beyond static, post-training performance.
Key Differentiators
| Feature | Traditional LLM Training | DARWIN Approach |
|---|---|---|
| Code Modification | Manual human intervention | LLM-mediated, autonomous mutation |
| Self-Improvement | Post-training static | Iterative, self-refining via genetic algorithm |
| Memory & Context | Limited across runs | Persistent JSON memory for past actions & reasoning |
| Human-in-the-Loop | Direct programming | Bidirectional interface for guidance & requests |
| Scalability | Resource-intensive, single model focus | Designed for parallel training of multiple agents, evolutionary scale |
DARWIN introduces several novel approaches compared to traditional LLM training, focusing on autonomous self-improvement and robust system design.
DARWIN builds upon foundational theories of self-improving AI, drawing from Schmidhuber's Gödel machines, Darwin's evolutionary concepts, and recent advancements in evolutionary computation for LLMs. This theoretical underpinning guides its genetic algorithm-like approach to self-modification.
Key influences include the idea that LLMs can serve as effective mutation and crossover operations (Lehman et al., 2022) and frameworks like Self-Taught Optimizer (STOP) which demonstrated recursively self-improving code generation (Zelikman et al., 2024).
Recent work in agentic evolutionary workflows, such as those enabling LLM agents to modify logic and reasoning (Yin et al., 2025) and the Darwin-Gödel Machine (Zhang et al., 2025), directly informs DARWIN's design. These systems emphasize iterative improvement through beam search and LLM API calls for code optimization.
DARWIN aligns with these approaches by using LLM agents to modify training code, but places a strong emphasis on safe containerization and automated, fault-tolerant iteration, bridging theoretical self-improvement concepts with practical, deployable LLMs.
DARWIN's architecture is built around four core modules: a central controller, a mutation script, a fitness evaluation step, and a utilities script for memory and HITL communication. This integrated design facilitates evolutionary optimization.

The core of DARWIN is an iterative evolutionary loop where GPT agents modify code, train, and the best performers are selected for the next generation.
Robust Isolation with Containerization
| Aspect | Without Containerization | With Containerization (DARWIN) |
|---|---|---|
| Code Isolation | Risk of unintended system-wide changes, conflicts | Individual agent sandboxes prevent cross-contamination |
| Security | Higher risk of malicious/erroneous code execution | Mitigates dangerous behaviors, manual checks in PoC |
| Reproducibility | Difficult to ensure consistent environments | Standardized environments for each training instance |
| Scalability | Challenging to manage multiple parallel runs | Facilitates parallel training of multiple agents concurrently |
DARWIN employs containerization to ensure robust isolation, security, and reproducibility for each evolving agent, a critical component for self-improving systems.
Empowering Human-in-the-Loop Intervention
DARWIN incorporates a bidirectional Human-in-the-Loop (HITL) interface. This allows the AI agent to request upgrades (e.g., additional datasets, training scripts, file restructuring) and for human operators to provide guidance and approve modifications. This collaborative approach enables the system to evolve beyond self-contained code changes, addressing broader bottlenecks like resource availability and architectural organization, and ensures ethical oversight.
Persistent JSON-Based Memory
DARWIN utilizes persistent JSON files to store a history of past reasoning, code changes, and their correlated performance results. This memory system provides crucial context for future decisions, enabling the agent to learn from successful and unsuccessful mutations. An ablation study showed a 3% worse performance without this memory, underlining its importance for informed, iterative self-improvement.
In initial experiments, DARWIN demonstrated promising capabilities over 5 generations of training with nanoGPT and OpenAI API (GPT-40-mini).

nanoGPT as a Proof-of-Concept Framework
DARWIN demonstrated its proof-of-concept capabilities by integrating with nanoGPT as the base training framework. This allowed for evaluation of LLM-driven code modifications on a simplified, yet representative, GPT model. The use of OpenAI API (GPT-40-mini) for mutation prompts showcased the potential for external LLMs to guide self-improvement, even with budget and time constraints.

DARWIN's current implementation serves as a proof-of-concept. Future work will focus on scaling the framework to more complex models (e.g., GPT-2 and beyond) and implementing better benchmarks for linguistic, mathematical, and coding tasks.
Scaling will necessitate distributed architectures utilizing GPU clusters for parallel agent training. Further research will explore more sophisticated automated error detection and resolution, alongside expanding the HITL interface to encompass even broader system modifications and resource requests.
