fix: gptmodel update

[Shubhangi-Microsoft]

This pull request updates the deployment to use the newer gpt-5-mini model instead of gpt-4.1-mini throughout the codebase, infrastructure, and documentation. It also updates the default model version, capacity recommendations, and related parameters to align with the new model. Additionally, minor improvements were made to resource deployment scripts and code owners.

Model Upgrade and Configuration Changes:

• Updated all references, parameters, and defaults from gpt-4.1-mini to gpt-5-mini in the deployment scripts (infra/main.bicep, infra/main.json, Deployment/checkquota.ps1, Deployment/quota_check_params.sh, .github/workflows/CI.yml) and documentation (docs/AVMPostDeploymentGuide.md, docs/CustomizingAzdParameters.md, docs/QuotaCheck.md). [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
• Updated the default GPT model version from 2025-04-14 to 2025-08-07 in all relevant configuration files and documentation. [1] [2] [3] [4]

Documentation Updates:

• Revised documentation to reflect the new model name, version, and recommended capacity for quota checks and deployment guidance. [1] [2] [3] [4] [5]

Infrastructure and Deployment Improvements:

• Added availabilityZones: [] to the managed cluster configuration to avoid issues in regions/subscriptions without availability zones. [1] [2]
• Fixed the dependency order for DNS zones in the generated ARM template to ensure proper deployment sequencing.

Maintenance:

• Corrected usernames in the .github/CODEOWNERS file for consistency.This pull request makes several important updates to transition the default GPT model from gpt-4.1-mini to gpt-5-mini across the codebase, documentation, infrastructure templates, and deployment scripts. In addition, it introduces a new AKS (Azure Kubernetes Service) module and updates the default VM SKU for agent pools. These changes ensure that deployments and documentation are aligned with the latest model versions and infrastructure best practices.

Key changes:

Model Upgrade and Configuration

• Updated the default GPT model from gpt-4.1-mini to gpt-5-mini throughout infrastructure templates (infra/main.bicep, infra/main.json), deployment scripts (Deployment/checkquota.ps1, Deployment/quota_check_params.sh), CI workflows (.github/workflows/CI.yml), and documentation. The default model version was also updated from 2025-04-14 to 2025-08-07. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]

Infrastructure Enhancements

• Introduced a new AKS (Azure Kubernetes Service) wrapper module in infra/avm/modules/compute/kubernetes.bicep to standardize and simplify AKS cluster deployments with configurable parameters and outputs, including identity principal IDs.
• Updated the default VM SKU for the AKS agent pool from Standard_D4ds_v5 to Standard_D4ds_v6 and explicitly disabled zonal placement to improve compatibility across regions. [1] [2]

Documentation Updates

• Revised documentation to reflect the new default GPT model, version, and recommended quota/capacity guidelines. This includes parameter tables, quota check instructions, and deployment guides. [1] [2] [3] [4] [5]

Maintenance and Minor Fixes

• Corrected user handles in the .github/CODEOWNERS file for consistency.
• Minor reordering in deployment dependencies for improved reliability in infra/main.json.
• Updated Bicep template hash to reflect infrastructure changes.## Purpose

Pull request overview

This PR updates the solution’s default Azure OpenAI model configuration from gpt-4.1-mini to gpt-5-mini (including model version), and makes related infrastructure and documentation adjustments. It also updates AKS infrastructure defaults (agent pool VM SKU and zonal placement behavior) and adds a new AKS wrapper module under infra/avm/modules.

Changes:

• Switch default GPT model to gpt-5-mini and version to 2025-08-07 across infra templates, CI, scripts, and docs.
• Update AKS agent pool default VM SKU to Standard_D4ds_v6 and explicitly disable availability zones in the main infra template.
• Add a new AKS AVM wrapper module (infra/avm/modules/compute/kubernetes.bicep) with parameters and outputs.
