    Simon Willison has pointed out several examples of prompt injection attacks and why it may never be a solved problem:

    I want more people to have link blogs.

    I have one in the sidebar of which I've been running since November 2003. You can search through all 6,836 links here:

    I can post things to it with a bookmarklet. It has an Atom feed.

    It's such a low-friction way of publishing. A lot of works like this too. I also like and for this.

    I'd love to see more of these.

  • Moving Away from Substack

    My approach is to publish to my own blog at and then copy and paste content from that into a Substack newsletter at a few times a month.

    It's been working really well.

    Substack don't have an API, but they do support copy and paste - so I built myself a tool that assembles my blog content into rich text I can copy and paste straight into the Substack editor.

    I wrote about how that works here:

    Hah, yeah securing something like WordPress can be a challenge, especially if you're running a bunch of plugins.

    My blog is a pretty straight-forward Django setup without many other dependencies, so it's a lot less of an attack surface:

  • Show HN: Superfunctions – AI prompt templates as an API
    1 project | | 20 Aug 2023
    That specific prompt is just an example and it's pretty bad, it was the shortest and simplest prompt I could come up with that would be easily understood.

    You can set response content-types (text, html, json, etc...). If you use json it will get pretty good results because I have some is some logic to attempt to pick out json or json5 objects from the text output. I dont yet have logic to support json arrays, but I'm hoping to add that soon.

    But still client side validation is needed for applications with untrusted input. I dont attempt to solve prompt injection. I saw a lot of interesting posts on this topic from this blog I need to find sometime to read more about it.

    Try this one instead, it should be better

    I've started to consider "commit to writing about it" as the price I have to pay for giving into the lure of another project. It's one of the main reasons I publish so much content on and

    A project with a published write-up unlocks so much more value than one which you complete without giving others a chance of understanding what you built.

    I've maintained internal blogs (sometimes just a Slack channel or Confluence area) at previous employers for this purpose too.

    I think you are asking specifically about practical LLM engineering and not the underlying science.

    Honestly this is all moving so fast you can do well by reading the news, following a few reddits/substacks, and skimming the prompt engineering papers as they come out every week (!). provides an early manifesto for this nascent layer of the stack.

    Zvi writes a good roundup (though he is concerned mostly with alignment so skip if you don’t like that angle):

    Simon W has some good writeups too:

    I strongly recommend playing with the OpenAI APIs and working with langchain in a Colab notebook to get a feel for how these all fit together. Also, the tools here are incredibly simple and easy to understand (very new) so looking at, say, or and digging in to the prompts, what goes in system vs assistant roles, how you gourde the LLM, etc.
