[openminddev]

This pull request updates the LLM model pricing tables in both the docs/api-reference/introduction.mdx and mintlify/api-reference/introduction.mdx files.

Major updates to LLM pricing and documentation:

Model categorization and structure:

New models and pricing updates:

• Added several new models across providers, including gpt-5.2, grok-4-fast, anthropic/claude-haiku-4.5, and others, with their respective input and output token prices.
• Updated and corrected token pricing for existing models to reflect current rates and ensure accuracy.

Provider-specific enhancements:

• Expanded the Near AI and Open Router sections with additional models and updated pricing details, increasing coverage of available options.

Formatting and clarity improvements:
