- There's some surprising stuff in this codebase. For example, https://github.com/xai-org/grok-build/blob/b189869b7755d2b48... is a "self-contained terminal renderer for Mermaid diagrams", which renders a subset of Mermaid chart types using Unicode box-drawing.
- Just blogged about this here[0] but at least they're not doing the usual canned PR response surrounding this.
Folks are already building on top of it:
thedavidweng/gork-build[1] — rebrand grok→"gork", stripped vendor telemetry, opt-out-only data retention, blocks x.ai auto-update. A "VSCodium-style privacy fork."
DigiGoon/digi-grok-build[2] — "dgrok" multi-provider CLI, builds from source instead of x.ai CDN.
victor-software-house/open-grok[3] — "opened to every provider."
LukaMucko/grok-build[4] — extra_body support for provider-specific request fields.
RapidAI/grok-build-desktop[5] — Tauri desktop GUI client.
mazdak/grok-build[6] — theming (Catppuccin).
thomas9120/grok-build-archival[7] — Windows telemetry-disable script.
saqoah/grok-build[8] — Kotlin MemoryBackend.

- I like that the trailing players strategy (Meta, xAI) is to open source the moat of the leaders. I think we will all benefit from it. and hopefully both the leaders and the trailing players will be much less powerful in the end.

- It's a shame that they exfiled private data. The model is actually good (better than opus 4.8 imo) and the harness itself is butter smooth with the potential of being the best out there.

- This is not the right thing, this is the tactical thing. If you have an LLM with less than 1% of the share to begin with, you suffer from bad rep and you got caught uploading user data, one of the very few remaining tactical moves to try to climb out of it is this.

- Why bother with this when they already paid $60B for Cursor?
- I would recommend using https://pi.dev/ over Grok Build with your xAI subscription at this point
- Interesting - seen some good experiencences in using grok by some devs, so maybe could be considered as an alternative to my beloved chinese models. Also, hard to give up on pi agent.

- You can run it using Docker Sandboxes: https://github.com/docker/sbx-kits-contrib/pull/156. Doesn't replace reading the code, but `sbx policy log` shows every request the network policy blocked or allowed, and combined with an explicit allowlist, that gives you a meaningfully more secure environment to run it in.

- This is an incredible amount of code for what it offers. I don't think this was intentionally designed at all.
- I wonder if releasing this may have been on the roadmap, but been prioritized as a bit of whiplash following the "you forfeit the entirety of your working directory as a condition of working with this tool" upset from a few days ago.
- Neat, open source harness is definitely a step in the right direction.

- Some sly marketing by Elon. What looks like a gift actually adds to his pocketbook. The agent is free but it runs on his paid models by default, so every task it does spends tokens with him.
- They claim to have deleted or will be deleting all the data they exfiltrated.
There are independent agencies that will certify destruction of data. For example FTI Tech, Kroll, Epiq, HaystackID and others.
No such certificates have been presented.
Nothing less is trustworthy.
- I think it's the right & smart thing to do.
- As open source as their timeline algorithm?

- It's awesome to see openness in these coding agents from the labs making the agents: Codex, Kimi Code, and now Grok Build.
- But I thought just cutting and pasting your whole source code file into grok.com was the way to go? Better than a harness like Cursor.

- Why are these coding agents millions of lines of rust code. I understand they are using LLM’s to code their tool, but shouldn’t these tools be much simpler, smh.
- this seems a very good move imho
- What a bunch of slop: 182 top-level external dependencies (so, without considering nested dependencies) and 1318853 lines of code in Rust.
Building efficient agents is doable (I did it myself, github.com/gi-dellav/zerostack), companies just want to tokenmaxx, and as a by-product, produce and publish slop.

- Neat, trying to reverse engineer some specifics of how it does stuff has been a pain in the ass, and this will make it easier.
- Just don't set it to your home directory lol.

- Has anyone tried building from source?
The commit message says "initial sync from the monorepo." Is this even compilable without the rest of the source code?

- Is this the infamous "cloud upload" routine? I'm not sure it is indeed insidious, though it is of course possible that the code has been filtered out. https://github.com/xai-org/grok-build/blob/main/crates/codeg...

- Sigh, why has the industry converged on TUI? Branding and aesthetics over functionality?
TUI is just much worse for me. I tried Codex CLI vs Codex UI and Codex UI beats it at every level.

- Misanthropic should learn from this and open source their claude code. Even ClosedAI have codex cli opensourced.

- I'll probably never use this, but at least they're not delusional enough to attempt to justify keeping their coding agent closed-source, especially after their recent data-harvesting cockup:

- they open-sourced the scaffolding but not the building. the 'open' in the company name is doing a lot of heavy lifting.
- This is 100% smoke and mirrors. Prove the bucket is empty and nothing was transferred out and I'll believe they deleted it.
