Editor's Note
Welcome to another installment of The Blitzy Blitz, a weekly newsletter showcasing what Blitzy is building. Follow along to see updates in the Open Source Enhancement Initiative, Building With Blitzy and Blitzy Diaries series on our blog.
The most recent experiment result was: Blitzy Scores a 64.78% on SWE Atlas Codebase QnA, see below for details!

Welcome Back

From busting software engineering benchmark leaderboards to breaking the boundaries of codebase voices, Blitzy has been busy this week.

Let’s get into it.

Blitzy Scores a Record on SWE Atlas Codebase QnA

Let’s kick off with the latest release: Blitzy Scores a 64.78% on SWE Atlas Codebase QnA.

SWE Atlas Codebase QnA is a professional software engineering benchmark that measures deep codebase comprehension prior to any code changes.

Blitzy’s record performance of 64.78% highlights the efficacy of our platform’s approach to reverse engineering.

Guess that Codebase

A direct product of infinite code context, Blitzy writes uncanny clues in the voice of various open source projects.

To showcase this skill (& have some fun), we started a series on our X account.

Every week, we pick one open source project.

4 clues come out each week.
1 clue dropped each day Monday-Thursday.
Finale with a reveal every Friday.

Events & Initiatives

Rethinking Legacy Modernization with AI

AI tools work well… until they encounter a complex enterprise codebase with millions of lines of code, decades of undocumented logic, and systems no one fully understands anymore.


Join AI Solutions Consultant David Byrne to learn about how to minimize the context bottleneck, see real-world examples of modernizing software with agentic development, and more.

Blitzy x OpenAI

There’s been another exciting development in Blitzy’s partnership with OpenAI!

With the release of GPT-5.6 Luna, the Blitzy platform can handle 2.2x more context and use 8.5x fewer tokens at a fraction of the cost (87% less).


State of Financial Services Engineering

At least 70% of mainframe modernization initiatives fail according to Gartner.


To address this exact problem, we recently released a white paper called “The State of Financial Services Engineering”.

Informed by data analysis from 100+ financial firms’ engineering roadmaps, the report is full of insights about feature development, modernization, 2027 projections, and more.

If you care about where software development is going, follow along.

We are just getting started, so stay tuned.

Back in a blitz,
