• Added "When to use Instant Clusters" use cases (moved from bottom of page)
• Reorganized "Get started" CardGroup with clearer descriptions
• Added "How it works" section with mermaid architecture diagram showing network topology
  (eth0 for external, ens1-ens8 for internal cluster communication)
• Consolidated "Supported hardware" section (GPU types and networking speeds)
• Added "Pricing" section with links
• Moved enterprise CTA to end of page

instant-clusters/configuration.mdx - New technical reference page:

• Environment variables table (PRIMARY_ADDR, NODE_RANK, NUM_NODES, etc.)
• Network interfaces documentation (ens1-ens8 for internal, eth0 for external)

hub/ai-coding-tools.mdx	public-endpoints/ai-coding-tools.mdx
hub/public-endpoint-reference.mdx	public-endpoints/reference.mdx

public-endpoints/overview.mdx - Rewritten overview:

• Added "Why use Public Endpoints?" benefits section
• Added "When to use Public Endpoints" guidance
• Added mermaid diagram showing request flow
• Added pricing summary table

one small thing: https://runpod-b18f5ded-promptless-ai-coding-tools-integration-tuto.mintlify.app/public-endpoints/models/wan-2-5
pricing is showing weird

[velaraptor-runpod]

for text models remove cogito and gpt-oss since they are not live to public
