Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static code scanning with hard-coded rules is used for validation, then validation speed is improved, but accuracy deteriorates due to inability to handle policy changes and architectural variations
Solution Approach 1:
The patent transitions from static hard-coded validation rules to a dynamic language model-based system that can adapt to changing policies and architectures. The LLM is fine-tuned on organization-specific policies and can dynamically adjust validation criteria without requiring code changes, resolving the contradiction between fast validation and accurate adaptation to policy changes.
Solution Approach 2:
The system changes the parameters of the validation approach by using fine-tuned language models with organization-specific policy embeddings. This allows the validation system to maintain high speed while improving accuracy through parameter adjustments in the model training process rather than structural changes to the validation logic.
2Measurement precision
If fine-tuning with organization-specific policies is implemented, then validation accuracy is improved, but training time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by fine-tuning the language model in advance on organization-specific policies and storing the trained model for reuse. This initial training investment creates a validated model that can then perform rapid validations without requiring retraining, converting training time into long-term validation efficiency.
Solution Approach 2:
The system creates copies of the fine-tuned language model that can be deployed across multiple validation tasks. Once trained on organization-specific policies, the model can be replicated and used simultaneously for multiple IaC validations, distributing the training time investment across numerous validation operations.
3Adaptability or versatility
If language models are used for validation, then adaptability to policy changes is improved, but risk of hallucinations and incorrect output increases
Solution Approach 1:
The patent implements feedback mechanisms where the language model's validation output is evaluated against ground truth data from organization policies. The model receives feedback on its predictions and adjusts its outputs accordingly, reducing hallucinations while maintaining adaptability to policy changes through continuous learning from validation results.
Solution Approach 2:
The system introduces an intermediary layer between the language model and the validation decision, using fine-tuned embeddings of organization policies as a reference framework. This intermediary guides the LLM's output toward accurate policy-based validations while maintaining the model's adaptability, filtering out hallucinations through policy-aligned embeddings.
Data Source
AI summary
Methods, systems, and apparatus, including computer-readable storage media for validation of Infrastructure-as-Code (IaC) configurations with added context, using a language model. A validation system can receive a request to validate an IaC configuration file. The request can include the IaC configuration file to be validated, as well as identifiers for identifying the policy from which validation requirements should be used for validating the IaC configuration file. Pre-trained machine learning models for generating natural language and/or structured code output may be fine-tuned to reduce or eliminate hallucinations, vague. or incorrect output, using training examples of syntactically correct IaC configuration files. An embedding repository of syntactically correct IaC configuration files and a repository of policy documents can be queried for augmenting the prompt to the language model.
