#Quint, a language built on top of #TLA+ to make formal specifications more accessible.

Crazy that #LLM coding will make formal verification mainstream in the next 2 - 3 years.

Quint, an executable specification language for reliable systems

Quint is an executable specification language. Write specs you can run, simulate, and verify, so subtle bugs get caught before reaching production.

🌗 LLM 時代的 TLA+ 入門：用提示詞（Prompt）走向勝利
➤ 告別燒腦的邏輯推理，交給機器來驗證系統正確性
✤ https://emptysqua.re/blog/intro-to-tla-plus-for-the-llm-era/
許多工程師對 TLA+ 望而生畏，認為其語法如同 LaTeX 般晦澀難懂。然而，隨著先進大型語言模型（LLM）的崛起，生成 TLA+ 規格書已變得輕而易舉。本文透過經典的「豆子問題」，說明如何將系統邏輯定義為狀態機，並利用 TLA+ 的形式化方法驗證演算法的正確性。即使不需深究數學細節，透過 LLM 的協助，開發者也能定義狀態變更規則與公平性約束，讓機器自動檢查潛在錯誤，從而大幅提升系統設計的可靠性。
+ 這篇文章真是及時雨！我一直想嘗試 TLA+ 但都被語法嚇退，用 LLM 輔助確實是降低門檻的好策略。
+ 形式化驗證在處理複雜併發系統時極其重要，雖然學習曲線陡峭，但將其視為規格語言而非傳統代碼會更好理解。

Intro to TLA+ for the LLM Era: Prompt Your Way to Victory

You can go far without writing TLA+ syntax now, but you still need to understand temporal logic.

"✨ Welcome to the #future where #engineers run in terror from #TLA+ because it looks like LaTeX's evil twin 🤖✨! But fear not, our mighty #AI overlords can now spew out TLA like #confetti at a parade 🎉. Just remember, it's still your job to figure out what the heck it's actually doing 🙃."

Next week I am going to Tokyo to give a presentation at the ABZ 2026 conference. Title: “Identifying Design Flaws in a Lock-Free Task Pool with TLA+”. It is an “application in industry” paper, I will upload it and the slides a bit later

We specified an algorithm with the simple goal of confirming its correctness, and instead found numerous issues without an obvious way to fix them (if it is even possible). Finding this early saved us huge amount of time and resources, and i think the result is quite a bit unusual

ABZ is my favorite conference, it is about state-based #formalmethods like Alloy, Event-B and #TLA+. The papers are always interesting, and each conference has a “case study” track, in which practitioners specify the given system using any state-based method they want and describe the results and their observations. This time the system is an autonomous planetary rover

Side note: my first trip abroad was back in 2014, and it was also to speak at ABZ :) I even met and spoke with Jean-Raymond Abrial!

🌗 大型語言模型能否以 TLA+ 建立真實系統模型？
➤ 從「教科書式復述」到「精確建模」的挑戰
✤ https://www.sigops.org/2026/can-llms-model-real-world-systems-in-tla/
本文探討了大型語言模型（LLM）在進行系統形式化驗證時的侷限性。研究團隊發現，LLM 雖然能流暢地編寫出符合語法的 TLA+ 規範，但往往只是在「背誦」教科書上的演算法原型，而非真正反映如 Etcd 或 ZooKeeper 等真實軟體的實作細節。為了區分兩者，團隊開發了 SysMoBench 基準測試框架，透過語法、運行、一致性及不變量檢查四個階段，精確定位模型與實際程式碼間的邏輯偏差，揭示了 LLM 在抽象化實作邏輯上的核心挑戰。
+ 這篇文章點出了 LLM 的一個盲點：它們很會模仿常見模式，但在面對需要深入理解特定實作細節的系統架構時，很容易產生幻覺或忽略關鍵的業務邏輯。SysMoBench 是一個非常務實的評估工具。
+ 對於分佈式系統工程師來說，這非常有價值。我們常說 TLA+

Can LLMs model real-world systems in TLA+?

Editors’ note: AI has been actively pushing the frontier of applied formal methods for computing systems. In this article, the Specula team wrote about their experience of evaluating LLMs on modeling system code, the basic capability for agentic model checking, using TLA+, a specification language f

Can #LLMs model real-world systems in TLA+? 🤔 Oh sure, because who wouldn't want a linguistically confused #AI applying #logic it doesn't truly comprehend to complex systems modeling? 🙄 Next up: teaching your cat to do your taxes! 🐱💼
