Twitter just open-sourced their algorithm.

Some initial takeaways:
◆ Your following to follower ratio matters.
◆ @TwitterBlue subscribers do get a boost in the algorithm.

Will keep adding more to this thread 👇
1. Your following-to-follower ratio matters.

Twitter's "Tweepcred" PageRank algorithm reduces the page rank of users who have a low number of followers but a high number of followings.

dub.sh/tweepcred
2. It looks like @TwitterBlue subscribers do get a boost in the algorithm.

Source → dub.sh/twitter-blue-a… Image
3. Twitter identified 4 different user groups to track & compare how often their tweets are being impressed to users:

◆ Power users
◆ Democrat users
◆ Republican users
◆ @elonmusk

Source → dub.sh/twitter-user-g… Image
@elonmusk 4. There are a few factors that determine if your tweet will appear on someone's "For You" tab, mainly, the probability the user will:

◆ like/RT your tweet
◆ click into your tweet & reply/stay there for >2 mins
◆ check out your profile 👀

Source → dub.sh/twitter-for-you
5. Some negative feedback loops that will reduce your "reputation score" on Twitter:

◆ Getting blocked
◆ Getting muted
◆ Abuse reports
◆ Spam reports
◆ Unfollows (not as heavily penalized as the above 4 though)

Source → dub.sh/negative-signa… Image
6. To put these feedback loops in perspective:

A user clicking on your tweet staying there for >2 min is weighted 22x more than them just liking your tweet

If they click into your profile through your tweet & likes/replies to a tweet? 24x more than a like.

If they reply to… twitter.com/i/web/status/1…
7. When needed, the government can intervene with the Twitter algorithm.

In fact, @TwitterEng even has a class for it – "GovernmentRequested"

Source → dub.sh/twitter-gov-in… Image
8. Presidential elections is also another big part of the Twitter Algorithm.

It can:
◆ Recommend election candidates to follow: dub.sh/twitter-gov-el…
◆ Suppress misinformation during Election events: dub.sh/twitter-gov-el… ImageImage
9. So far, I've scoured both the Twitter Algorithm repos but I still haven't found anything about the following:

◆ If a tweet containing a link will be ranked lower
◆ If bookmarking a tweet will boost its rankings

It looks like these are more myths than facts but I'll report… twitter.com/i/web/status/1…
10. In the current light ranking model (Earlybird), tweets with images & videos seem to get a nice 2x boost → dub.sh/earlybird-medi…

However, this is an old model that Twitter is planning to rebuild completely, so things might change → dub.sh/earlybird Image
Update: I added all of the above into the blog post below, will keep updating it as things change.

For example, the 4 user groups tracked by Twitter (point #3) has already been removed in this massive PR: github.com/twitter/the-al…

steventey.com/blog/twitter-a…
Some additional learnings:

11. The algorithm will consider more of your tweets if you have a high TweepCred

E.g. if your TweepCred is <65, the ranking algorithm will only consider up to 3 of your tweets.

But with >65 TweepCred, the limit is lifted.

→ dub.sh/twitter-anti-g… Image
12. Your tweet's relevancy decreases over time.

At a rate of 50% every 6 hours, to be exact.

→ dub.sh/tweet-decay-sc… Image
Update: Bookmarks will start weighing as much as likes, if not more: steventey.com/blog/twitter-a… Image

Introducing my new open-source side project:

It's a crowdsourced list of the best open-source projects on the web.

Best part? It's dogfoods @dubdotco's API to create short links for each project page + display real-time click analytics for them 📈 oss.gallery
Here's the full tech stack:

◆ @nextjs Server Actions + Form Actions (zero API routes)
◆ @dubdotco's TypeScript SDK ()
◆ @tremorlabs for charts
◆ @vercel Postgres + deployment

The code is fully open-source – go check it out: 👇d.to/sdk
oss.gallery/github
Here's how we used the @dubdotco SDK for this project:

1. Creating/editing links – dub.links.create and dub.links.update:

2. Fetching the time-series analytics for a given link – .timeseries: git.new/UrBg1z5
dub.analytics
git.new/Rkio6cN
const { shortLink } = await dub.links.create({ url, externalId: linkId, }); await dub.links.update(`ext_${link.id}`, { url: newUrl, }) const data = await dub.analytics.timeseries({ externalId: `ext_${link.id}`, interval: "30d", });

Life update: I'm starting a company around 🚀

We're building the link management infrastructure for you to create marketing campaigns, link sharing features, and referral programs.

Here's how it all started – and where we're going: Dub.co
Image
@dubdotco Quick backstory: I built Dub​ as a side project to solve an internal need we had @vercel – sharing links on @X with nice OG images.

The product was fully open-source and quickly gained a lot of traction (#1 on Hacker News + 14K stars on @github).

Since then, Dub kept growing – mostly through word of mouth, without spending a cent on paid marketing.

And we're just getting started.

Introducing Shooketh – an AI bot fine-tuned on Shakespeare's literary works:

It's fully open-source and built with:
◆ @OpenAI's new fine-tuning feature
◆ @nextjs + @vercel AI SDK

Full guide on fine-tuning in thread 👇 vercel.fyi/shooketh
So, what is fine-tuning?

It's akin to prompt engineering, but instead of customizing GPT via a prompt at every user request, you are customizing the *base model* itself.

Analogy: getServerSideProps vs getStaticProps in @nextjs 👇

→ vercel.com/guides/fine-tu…
What is Fine-tuning? Similar to prompt engineering, fine-tuning allows you to customize gpt-3.5-turbo for specific use cases. However, instead of customizing them via a prompt every time the user interacts with your application, with fine-tuning you are customizing the base model of gpt-3.5-turbo itself. A great analogy for this is comparing Next.js' getServerSideProps vs getStaticProps data fetching methods: getServerSideProps: Data is fetched at request time – increasing response times (TTFB) and incurring higher costs (serverless execution). This is similar to prompt engineering, wher...
@nextjs Benefits of fine-tuning over prompt engineering:

◆ Token savings (no need to have a massive prompt)
◆ Faster response times (ditto smaller prompt)
◆ Better quality results (tailored to the exact behavior you want) Screenshot of the following quote: Early tests have shown a fine-tuned version of GPT-3.5 Turbo can match, or even outperform, base GPT-4-level capabilities on certain narrow tasks.

▲ @vercel just launched the AI SDK.

You can now build AI-powered apps with streaming – starting with one simple command: `npm i ai`

Here are some examples👇 Illustration of the Vercel ...
But first, why streaming?

Here are 2 examples – the first uses a blocking UI, while the second uses a streaming UI.

As you can see, the streaming UI is able to start displaying the response much faster than the blocking UI.

Try it out for yourself: vercel.fyi/Gb6nMzv
Example #1: Chat interfaces

With the `useChat` hook, you can build a simple yet beautiful chat interface w/ streaming in just a few lines of code.

For reference, I built the following example in <10 mins with this hook.

I spent the weekend upgrading dub.sh to @nextjs App Router.

Featuring:
◆ Segment-level caching
◆ Server components
◆ Parallel & intercepting routes
◆ Dynamic OG images + Metadata API

Here's what I learned 🧵
1. You can now cache individual fetch calls via segment-level caching.

Combine static, dynamic, and revalidated data inside reusable components. E.g. on @dubdotsh's homepage:
◆ GitHub star count: 60s
◆ Tweet testimonials: 1hr

The best part? Detailed logs for each cache hit 😍 Image
2. Server components help you write less code.

No more bulk fetching data inside getStaticProps and prop drilling all the way down to your child component – just use a server components instead.

Here's the (much cleaner) index page after the migration: Image
