Github Copilot Wants to Play Chess Instead of Code

A GPT-3 product exposing GPT-3 outputs by design hardly is "breaking"

So I asked it to do this:

    # Evaluate a Lisp S-expression
    def eval_list(s):
This was the third suggestion:

    def eval_list(s):
        if not s:
            return None
        if len(s) == 1:
            return s[0]
        if s[0] == 'quote':
            return s[1]
        if s[0] == 'if':
            if eval_list(s[1]) != False:
                return eval_list(s[2])
            else:
                return eval_list(s[3])
        if s[0] == 'set!':
            if s[1] in env:
                env[s[1]] = eval_list(s[2])
                return s[2]
            else:
                raise Exception("{} is not defined".format(s[1]))
        if s[0] == 'define':
            if s[1] in env:
                raise Exception("{} is already defined".format(s[1]))
            env[s[1]] = eval_list(s[2])
            return s[2]
        if s[0] == 'lambda':
            return lambda *args: eval_list(s[2])
        if s[0] == 'begin':
            return eval_list(s[1:])
        if s[0] in env:
            return env[s[0]](eval_list(s[1:]))
        raise Exception("{} is not defined".format(s[0]))
Huh! Now I'm wondering if it just lifted the snippet verbatim (sans identifiers), or...

It is useful in my day-to-day work, and I consider it an assistant. It understands deeply and often comes up with the right answer. It's great, and I'd happily pay for it.

Great. Now they've done it:

> This is not trivial at all, note that this is not actually the original general purpose GPT-3. Codex has 12-billion parameters compared to GPT-3’s 175 billion and it was trained only on open source code. The fact that it does so well is insane to me!

It's not that surprising. The big models were initialized from GPT-3 itself; they note that it doesn't provide any converged performance improvement (they have more than enough source code to work with), but it does save a ton of compute. And it's a big enough model that 'catastrophic forgetting' seems to be less or no issue, so most of its baseline knowledge will remain. (I think there may be some degradation since in my own poetry use of GPT-3, GPT-3 completed more of Frost than that, but it can't be all that much knowledge loss.)

To save you a click, it will autocomplete answers if you give it questions:

``` q: Are you there? a: ```

And it will autocomplete an answer:

``` q: Are you there? a: Yes, I am here. ```

Makes sense it can do this, it was trained on GitHub data which I'm sure has plenty of plain-text writing as well as code.

It knows classic songs to!

Started with "we're no strangers" and it knew the score.

I found Copilot to be a great helper to write the documentation for the product that I am working now. I just type a few words and this thing suggests the rest of it. Never was documentation process easier for me!

Would hardly call this breaking it.

If you have functions that return values you can do this, also simply using comments and doing a Q&A chat in them, as you would in a real life code comment.

I use Copilot to write test. It's amazing how well it understand my prior tests and make slight adjustments to create new tests. I really enjoy using it.

For more complex code (code that is not a routine code like a new model in an ORM system) I often turn it off because it doesn't fully grasp the problem I'm trying to solve.

I would only use it if it had separate models trained on non-GPL-licensed code, or if it could link to the exact code used.

It is interesting that it believes Joe Biden is the VP as well as the President and Kamala Harris is a Representative for California's 17th congressional district. Stale data perhaps?

Interesting that it calls itself Eliza, like the NLP software from the 60s (https://en.wikipedia.org/wiki/ELIZA)

I find these made-up "conversations" to be super boring. You're not "talking" to the AI, it's just predicting what the next sentence in the document might be. There is no plan behind this, the output may be mildly amusing, but that's about it.

Yet that seems to be the only thing everyone trying out GPT-3 is interested in...

Copilot writes far better API doc comments than most human programmers.

I've been using copilot to write markdown files for a while already and it's really useful. Like the Gmail/Google docs autocomplete but way better.

It's also nice that it uses the structure of the current file and (I think) context from your codebase, so i.e. if you're writing structured documentation, it's occasionally able to write out the whole function name with arguments with descriptions, all in the right format. Very impressive.

So, it apparently also has some strong opinions, a high opinion of itself, and wants to play chess instead of code.

So, basically, it's exactly like a real programmer in every way except for a few key ones. I wonder what its preferred food choices are.. and if it likes Almost Pizza(tm).

I love playing with it like this! One cool thing I've seen it do is translation! E.g

> en: Hello, my name is Sam.

> fr:

And it writes the next sentence in French! And you can keep going to get other languages.

I really thought the author was going to start writing chess notation and Copilot would actually play a game, that would have been impressive.
