PJ Celis founded Judge.me, the reviews app on a lot of Shopify stores, where the plan is either free or $15 a month. The second product is priced differently: email is metered at 15 cents per 1,000 sent once you pass the free 15,000 a month, so this bill moves with the sending. The comparison a store will make is Klaviyo, which prices on how many contacts you hold rather than on what you send. Under the post a merchant paying about $2,300 a month for 750,000 emails a week asks whether he can move, and PJ puts 3 million emails a month at $450. The app has been listed since 14 July, he says it is still early, and a Klaviyo import is on the way. Plenty of the B2C founders here sell on Shopify with Judge.me already installed.

After 12 years of being focused on just reviews, we're adding a second product: @judgeme Email.

Priced super low: 0-15 USD / month for features, 15K emails per month for free, then 15 cents per 1000 emails.

That's 10x cheaper than the competition. Even compared to Shopify's own Email app, we're 85% cheaper.

The product is in early stages, but we're adding features constantly. The price will never go up as we add value, as we optimize for market share, not profit.

After you install the app, you'll be able to request a call with our team to go over your email marketing needs and your setup.

Very excited to have this app live, and if you're a Shopify merchant, hope to see you soon!

Vaibhav Srivastav is at OpenAI, and was at Hugging Face before that, so this is written from inside the team that shipped the model. The five lines in the middle are the part to keep: what to change in your own prompts and AGENTS.md now that Astra follows instructions more closely than the model before it.

GPT-6 Astra is now available to all Pro, Enterprise and Business Premium users in ChatGPT Work and Codex. It’s also live in the API.

It's a phenomenal model and I love every second working with it!

Astra follows instructions more closely, so revisit your prompts and skills:

> Make “can you…” mean “do it”: finish authorised work and prepare a reviewable result before seeking approval.

> Audit AGENTS.md and skills. Ask it to identify the exact file and rule blocking progress. Prioritise your request over skill guidelines.

> Specify short paragraphs, plain language and phrases to avoid.

> Ask for subagents on independent work when it improves speed or quality.

> Run relevant checks. Repeat or expand only for changes, failures or unresolved concerns.

To push it to it's limits, I gave it a prompt to build a real-scale video fly through of nürburguring track in blender and it did not disappoint!

Enjoy! ✨

Miguel Ángel is a product engineer at HeyGen, and HyperFrames is HeyGen's own product, so this is the model being used on the thing he builds all day.

Astra is so cracked at Blender.

You can literally one-shot game assets with it.
