Proposed Solution

Add model in the AI Gateway as an option. Each team can establish if this new model can be adopted with your prompts as they are or if prompt changes are needed to maintain quality.

Please use the unified model configuration file to apply the Claude 3.7 sonnet model.

Example model configuration changes for applying the correct parameters can be followed in this MR.
