Cerebras Inference template This val shows you how you can deploy an app using Cerebras Inference on Val Town in seconds. What is Cerebras? Cerebras is an American chip manufacturer that produces large wafer chips that deliver mind-blowing LLM inference speeds. As of this writing on Jan 17, 2025, Cerebras Inference provides Llama 3.18b, 3.1 70b, and 3.370b at a jaw-dropping 2k tokens per second – that's 50x faster than what the frontier labs produce. Llama 3.370b at 2k tokens per second is particularly noteworthy because it is a GPT-4-class model . This level of intelligence at that level of speed will unlock whole new classes of applications. Quick start Set up Cerebras Sign up for Cerebras Get a Cerebras API Key Save it in a Val Town environment variable called CEREBRAS_API_KEY Once Cerebras is set up in your Val Town account, there are two ways to get started: Fork this app and customize it (or ask Townie AI to customize it) Start a new chat with Townie AI and copy & paste the following instructions: . Use Cerebras for AI on the backend like so: const { OpenAI } = await import("https://esm.sh/openai"); const client = new OpenAI({ apiKey: Deno.env.get("CEREBRAS_API_KEY"), baseURL: "https://api.cerebras.ai/v1" }); const response = await client.chat.completions.create({ model: "llama-3.3-70b", messages: [], }); const generatedText = response.choices[0].message.content; For example, the val in this template was created by asking Townie AI to "Make a chatgpt clone", then I hit shift-enter twice, and then pasted in the instructions on how to use Cerebras from above, then hit enter. Townie built this app on its first try, in about 20 seconds. Sample apps Cerebras Searcher - a Perplexity clone that uses the SerpAPI to do RAG and summaries with Cerebras ( requires a SerpAPI key ) Cerebras Coder - an app that generates websites in a second with Cerebras Cerebras Debater - an app that truly shows Cerebras's speed: it's Cerebras talking to Cerebras in a debate

This is an AI code assistant powered by Cerebras , running llama3.3-70b. Inspired by Hassan's Llama Coder . Setup Sign up for Cerebras Get a Cerebras API Key Save it in a Val Town environment variable called CEREBRAS_API_KEY

New Stripe Subscription Handler This val processes new Stripe subscribers to Val Town Pro. It sends our team a Discord notifcation and sends a welcome email to the new subscriber. It takes a couple of steps if you'd like to set up something similar for your own Stripe account. Setup Fork this HTTP val Create a new webhook in Stripe Add your val's HTTP endpoint URL into the Stripe webhook Select customer.subscription.updated as the only event to listen to (more on this below) Add your stripe_sk_customer_readonly to your Val Town Env Variables Add your webhook's signing secret as STRIPE_WEBHOOK_SECRET to you Val Town Env Variables How the code is structured Verifies the signature to make sure it's really from Stripe Filters out only newly created subscriptions Sends off the Discord message & email Which Stripe event type to listen to Stripe sends webhooks for many different kinds of events. Relevant for us here are: customer.subscription.created (what we used to listen for) customer.subscription.updated (what we're currently listening for) The issue with customer.subscription.created is that it triggers too early, before the user's payment actually goes through. This is a problem because in early Nov 2024 we started getting credit card fraudsters testing cards using our service. We started getting lots of notifications for new subscriptions that never actually became active. Note: if anyone knows good ways to prevent that sort of behavior at the root, please let me know by commenting on this val! In order to only get notified on a valid subscription, we now subscribe to customer.subscription.updated . This event happens on any subscription change, including renewals and cancellations, so now we have to filter those events to only get new subscriptions, ie where: event.data.previous_attributes.status === 'incomplete' && event.data.object.status === 'active'

☔️ Umbrella reminder if there's rain today Setup Fork this val 👉 https://val.town/v/stevekrouse.umbrellaReminder/fork Customize the location (line 8). You can supply any free-form description of a location. ⚠️ Only works for US-based locations (where weather.gov covers). How it works Geocodes an free-form description of a location to latitude and longitude – @stevekrouse.nominatimSearch Converts a latitude and longitude to weather.gov grid – @stevekrouse.weatherGovGrid Gets the hourly forecast for that grid Filters the forecast for periods that are today and >30% chance of rain If there are any, it formats them appropriately, and sends me an email

Twitter/𝕏 keyword alerts Custom notifications for when you, your company, or anything you care about is mentioned on Twitter. If you believe in Twitter/𝕏-driven development, you want to get notified when anyone is talking about your tech, even if they're not tagging you. To get this Twitter Alert bot running for you, fork this val and modify the query and where the notification gets delivered. 1. Query Change the keywords for what you want to get notified for and the excludes for what you don't want to get notified for. You can use Twitter's search operators to customize your query, for some collection of keywords, filtering out others, and much more! 2. Notification Below I'm sending these mentions to a public channel in our company Discord, but you can customize that to whatever you want, @std/email, Slack, Telegram, whatever. Twitter Data & Limitations The Twitter API has become unusable. This val gets Twitter data via SocialData , an affordable Twitter scraping API. In order to make this val easy for you to fork & use without signing up for another API, I am proxying SocialData via @stevekrouse/socialDataProxy. Val Town Pro users can call this proxy 100 times per day, so be sure not to set this cron to run more than once every 15 min. If you want to run it more, get your own SocialData API token and pay for it directly.

AQI Alerts Get email alerts when AQI is unhealthy near you. Set up Click Fork Change location (Line 4) to describe your location.

Click Run Background This val uses nominatim's geocoder to get your lat, lon, and air quality data from OpenAQ. It uses EPA's NowCast AQI Index calculation and severity levels.

This is a very simple template for the kind of Bluesky bot I build. It's very much all over the place. e.g. it sets up the "Agent" to post (because that part is documented well), but doesn't use it to search for posts. You can do that if you want (if you do, look here ), but I like to simply rawdogg the API, so that is what I'm doing here. The custom Post type is incomplete and only contains the stuff I found relevant. Error handling is payed only lip service to (at best) as well. ...But it works for me! How to use If you want to use this, you will have to set 2 environment variables for your val: BLUESKY_USERNAME BLUESKY_PASSWORD From what I can tell from my testing: BLUESKY_USERNAME can be both the bot account's handle as well as the email you use to log into it with. BLUESKY_PASSWORD can be both the account's main password as well as an app password. The rest is commented in the code. If you have any questions, feel free to message me on Bluesky: Jonas-Merlin Schumacher (@jonasmerlin.bsky.social) — Bluesky
