Baidu just open-sourced an OCR model that reads entire 40-page documents in one shot.

It's called Unlimited-OCR. 3 billion parameters but only 500 million active during inference. Runs 100% locally on your machine.

Why this matters: traditional OCR tools chop documents page by page. Tables that span two pages break. Reading order gets lost. Cross-page context disappears.

Unlimited-OCR processes the whole document at once. 32K context window. Text, formulas, tables, reading order all preserved across pages.

Output comes out as clean structured Markdown.

→ 93% accuracy on the standard benchmark. +6 points over the baseline.
→ Error rate stays below 0.11 even past 40 pages.
→ Multilingual out of the box.
→ 2.12 million downloads on Hugging Face last month. 14,600 GitHub
stars.

For context: Amazon Textract, Google Cloud Vision, and Azure Document Intelligence all charge per page. This runs locally for free.

ALS + Header passing is a super clean flow! But the architecture nerd in me has to ask: How do you secure that FastAPI header from direct spoofing attacks? And once FastAPI resolves the tenant, are you managing dynamic connection pools or using Row Level Security? That DB layer is usually where the real tears happen! 😂

[Md Irfan Hasan Fahim @mihf05]

You want to know the real bottleneck of building a scalable multi-tenant ecosystem with Next.js and django or fastAPI?
It isn't the database. It’s handling middleware sub-domain routing and setting the dynamic tenant context provider at runtime.🧠
How are you handling dynamic tenant context? Webhooks or dynamic connection pooling? Let's talk architecture! 💭

[Md Irfan Hasan Fahim @mihf05]

When building multi-tenant SaaS, you have 3 main database isolation approaches:

1️⃣ Database-per-tenant: Highly secure, but cloud costs and maintenance will destroy you.
2️⃣ Schema-per-tenant: The perfect balance. Standard Postgres approach.
3️⃣ Shared DB with Row-Level Security (RLS): Cheapest option, but one bad "WHERE" clause in your code leaks the whole database. 💀
Which approach are you using? 🚀

[Md Irfan Hasan Fahim @mihf05]

Explaining multi-tenant database architecture to a non-technical founder is exactly like trying to teach a cat TypeScript. 😹

Imagine 20 different schools using your EdTech platform, sharing the exact same database, but entirely restricted from seeing each other's data.

Who else has lost their mind building multi-tenant SaaS? 👇

I absolutely hate writing PRDs (Product Requirements Documents). But I still write them so I don't cry while rewriting my NestJS backend three weeks later. 🥲

How much time do you actually spend scoping the business logic or mapping the architecture before you open VS Code? 💭

[Md Irfan Hasan Fahim @mihf05]

The worst code isn't the code that crashes in production.

The worst code is the code that perfectly builds a feature the user doesn't even need!

Forward Deployed Engineering (FDE) rule #1: Research the problem first. Code second. 🚀

Expectation: Spending all day with my headphones on, building beautiful Next.js UI components and clean APIs. ✨

Reality: Drinking 4 cups of coffee trying to figure out how 10 different educational organizations will share the same Postgres database in a multi-tenant SaaS without seeing each other's data! ☕💀

Backend life. 🥲 What are you building today? 👇
