Sorry, that is not what I think. It’s just that surely there was something very similar enough to your JSON to get the prediction to come up with something that looks similar enough.

That's the thing it's not that there was something similar to my specific problem. It's parts of many billions of problems that have been fed into the system have aspects that all come together to produce a solution for the particular problem. You don't even have to start with JSON, you can ask it to come up a JSON schema by simply giving it parameters.

I'm not nitpicking you, I'm pointing out that what you've described isn't actually how these things worked, and the way they do work is far more useful in practice. Let me give you a concrete example. Given a query of "write a json schema to represent a comment thread on a social media site like reddit", it'll do this bit of reasoning:

Okay, I need to create a JSON schema for a comment thread similar to Reddit. Let me start by breaking down what a Reddit-style comment thread includes.

First, each comment has an ID, author info, content, timestamps, votes, and replies. The replies are nested comments, forming a tree structure. So the schema should allow for nested objects within each comment's replies.

I need to define the required fields for a comment. The ID is essential, as is the content and author information. The author should have a username, maybe a profile link, and flags like is_mod or is_admin.

Voting information: upvotes and downvotes counts, and a total score. Also, whether the current user has voted, which could be an enum indicating up, down, or none.

Timestamps for when the comment was created and last edited. Maybe include an edited field that's either a boolean or a timestamp.

Replies need to be an array of comments, which means the schema will reference itself. That requires using "$ref" to point to the comment definition, allowing for recursion.

Moderation aspects: flags for removed, locked, spam, etc. Distinguish between user deletion and mod removal.

User mentions and links: comments might reference other users or contain URLs, so including arrays for those.

Awards or badges on comments, similar to Reddit's awards. Each award could have a name, image URL, and count.

Pagination for long threads? Maybe include a "continue_thread" field with a token for loading more replies.

Sorting options for replies (best, top, new, etc.), so a sort_order field with enum values.

Let me structure the schema with definitions. Start with the comment object, then define author, award, user mention, link, etc.

Required fields: id, author, content, created_at, score. Maybe others depending on necessity.

For the voting, current_user_vote should be an enum of "up", "down", or null.

Ensure that all optional fields are not required. For example, edited can be a boolean or a timestamp, but maybe just a timestamp if it's been edited.

Validation: each comment's replies must be an array of comment objects. Use "items" with "$ref" to the comment schema.

Testing edge cases: deleted users, removed comments, maximum nesting depth. But the schema might not handle depth limits, just the structure.

Include examples to illustrate how a comment with replies would look.

I think that covers the main aspects. Now, draft the schema with these considerations.

This alone is already useful because it goes through the steps of the problem, identifies some corner cases, and suggests what a good way to model this problem might be. It will then produce a json schema based on that:

{
  "$schema": "http://json-schema.org/draft-07/schema",
  "title": "Social Media Comment Thread",
  "type": "object",
  "definitions": {
    "comment": {
      "type": "object",
      "properties": {
        "id": {
          "type": "string",
          "format": "uuid",
          "description": "Unique identifier for the comment"
        },
        "author": {
          "$ref": "#/definitions/user"
        },
        "content": {
          "type": "string",
          "description": "Markdown-formatted comment content"
        },
        "created_at": {
          "type": "string",
          "format": "date-time"
        },
...
    "total_comments": {
      "type": "integer",
      "minimum": 0
    },
    "depth_limit": {
      "type": "integer",
      "description": "Maximum allowed comment depth"
    },
    "comment_limit": {
      "type": "integer",
      "description": "Maximum comments per page"
    }
  },
  "required": ["thread"]
}

it highlights key features of the solution

Key Features:

    Nested Comments: Recursive structure for replies

    Voting System: Track upvotes/downvotes and user's vote

    User Identity: Detailed author information

    Moderation: Flags for removed/locked/deleted content

    Awards: Support for Reddit-style awards

    Mentions & Links: Track user mentions and embedded links

    Sorting & Pagination: Handle different sort orders and partial threads

    Safety Features: Distinguish user deletion vs mod removal

This schema supports:

    Infinite nesting of comments

    Multiple sorting algorithms

    User reputation systems

    Content moderation tools

    Rich text formatting

    Pagination for large threads

    User interaction tracking

and it gives an example usage (I've truncated it for brevity)

{
  "thread": {
    "id": "550e8400-e29b-41d4-a716-446655440000",
    "author": {
      "username": "tech_fan42",
      "avatar": "https://example.com/avatar.jpg",
      "is_mod": false
    },
    "content": "This new framework is amazing! 🚀",
    "created_at": "2023-08-20T14:30:00Z",
    "score": 1542,
    "replies": [
      {
        "id": "3f3e6c60-3d7d-461d-aa7a-5c94f5d5dc5d",
        "author": {
          "username": "framework_author",
          "is_admin": true,
          "distinguished": "admin"
        },
        "content": "Thanks! Check out our [docs](https://docs.example.com/)",
        "created_at": "2023-08-20T14:35:00Z",
        "score": 893,
        "links": [
          {
            "url": "https://docs.example.com/",
            "text": "docs"
          }
        ]
      }
    ],
    "awards": [
      {
        "name": "Gold",
        "image_url": "https://example.com/gold.png",
        "count": 2
      }
    ]
  },
  "total_comments": 45,
  "depth_limit": 8
}

Now, given that schema, I can get it to produce a SQL schema from that, write the queries to do operations against the DB, etc. So, I can go directly from getting requirements in plain English, to having a reasonable data model, and a persistence layer in a span of a few minutes. I can also ask it to explain design decisions, make adjustments, etc.

This is far closer to pair programming with a second developer than hunting for code to glue together on Stack Overflow.
