The key insight: most token waste isn't from verbose content - it's from repetition. sqz keeps a SHA-256 content cache. First read compresses normally. Every subsequent read of the same file returns a 13-token inline reference instead of the full content. The LLM still understands it.

Real numbers from my sessions:

File read 5x: 10,000 tokens → 1,400 tokens (86% saved)

JSON API response with nulls: 56% reduction (strips nulls, TOON-encodes)

Repeated log lines: 58% reduction (condenses duplicates)

Stack traces: 0% reduction (intentionally — error content is sacred)

That last point is the whole philosophy. Aggressive compression can save more tokens on paper, but if it strips context from your error messages or drops lines from your diffs, the LLM gives you worse answers and you end up spending more tokens fixing the mistakes. sqz compresses what's safe to compress and leaves critical content untouched. You save tokens without sacrificing result quality.

It works across 4 surfaces:

Shell hook (auto-compresses CLI output)

MCP server (compiled Rust, not Node)

Browser extension (Chrome + Firefox (currently in approval phase)— works on ChatGPT, Claude, Gemini, Grok, Perplexity)

IDE plugins (JetBrains, VS Code)

Single Rust binary. Zero telemetry. 549 tests + 57 property-based correctness proofs.

cargo install sqz-cli

sqz init

Happy to answer questions about the architecture or benchmarks. Hope this tool will Sqz your tokens and save your credits.

f you try it, a helps with discoverability — and bug reports are extra welcome since this is v0.2 so rough edges exist.

It is available as IDE Extension , CLI via npm, cargo, pip , soon it will be able as web extension to use with chatgpt, claude, gemmini websites as well.

I am a recent IT graduate from India seeking full-time software engineer positions, preferably remote. I have experience working with LLMs, fine-tuning LLMs, RAG, open-source software development, machine learning, and web development. Recently, I worked at SAS as a Gen AI intern, I have done the Google Summer of Code at the Eclipse Foundation and worked as a full-stack intern at Eutech as well in the past. I am passionate and dedicated, with a current focus on Generative AI and LLMs.

I am only interested in full-time positions, not contract roles. However, I am open to research positions or internships that involve publishing research papers. Feel free to reach out to me.

Thank you.

Happy New Year Everyone! I hope you all are doing well.I am Ojus, a recent IT graduate and I'm looking for a job. I can join immediately. I'm interested in Software Development, C++,Python, Java EE, Jenkins, Debugging, AWS, Open Source, Web Development, and I'm open to trying out something new.

I have worked as a software engineering intern at Eclipse Foundation (Founded by IBM) as part of Google Summer of Code 2023, working on Eclipse Cargo Tracker with Reza Rahman (principal program manager at Microsoft).

Most of my programming experience during college has been with C++, Javascript and Python, and for the past four months, I’ve been writing code in Java by working on Eclipse Cargo Tracker, upgrading the codebase from Jakarta EE 8 to Jakarta EE 10 (Formerly Java EE) as part of Google Summer of Code. Read more about my GSoC contributions: [Link to Medium Article](https://medium.com/@ojuschugh1/gsoc23-work-product-submissio......)

Apart from that, I'm also interested in DevOps and Gen AI (still in the early stages of learning it).

I am committed to proving my capabilities and dedication if given the chance. Thank you for considering my request.

Thanks, Ojus.

Thanks to both you for the help :)

For ask section thread, i can see option to reply to others comment but unable to comment my own message.

Thanks and Regards

Right now as well I am unable to comment in the ASK:HN who wants to be hired(December,2023)even after you vouch me, why so ?.

I hope this message finds you well. I recently joined and am encountering an issue with commenting on ASK posts. I'm unsure if it's related to my low karma, as I only joined yesterday, or if I might be missing a step. Could someone kindly guide me on the correct process or inform me if there are any specific requirements for commenting?

Your assistance is greatly appreciated.

Thank you,
