@sjmaple @nvidia Yep, it’s definitely fun being in the same company :)

@john_eipe Thank you!

Its been equally exciting and humbling!

[Arun Gupta @arungupta]

How do you make token generation efficient using open and modular software?

This is where I'll be spending time going forward, and excited about it.

[NVIDIA AI Infrastructure @NVIDIAAIInfra]

AI factories generate intelligence in the form of tokens. The question is how many you can produce per watt.

NVIDIA DSX OS brings open, modular software to AI factories at scale—helping operators accelerate deployment, improve efficiency, and strengthen reliability across multi-tenant AI infrastructure.

CoPilot has a rubber duck mode: https://t.co/DeFGfkMmBN. Thanks @brunoborges for sharing this.

I do that all the time using agentctl https://t.co/ptVat8Yhx8.

[Arun Gupta @arungupta]

Fantastic interview!

[Arun Gupta @arungupta]

That's where agentctl start <issue> --agent codex/copilot comes in handy

[Arun Gupta @arungupta]

Aaaargh ..

"The @GitHubCopilot merge commit bloated the branch — it absorbed all of PRs #153, #154, and #155. The cleanest fix is to cherry-pick just the original feature commit" - @claudeai to the rescue

[Arun Gupta @arungupta]

HugOps to @github

[Arun Gupta @arungupta]

Its confirmed down: https://t.co/WOod18iWaI

Claude is down, getting 500 errors across the board

API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server
error"},"request_id":"req_011Ca22J6GNGmWMyY6KMwxBP"}

[Arun Gupta @arungupta]

@Shpigford @claudeai yep, same error

API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server

[Arun Gupta @arungupta]

@francesc @Apple Welcome back to the “free” world :)

[Arun Gupta @arungupta]

Its only mid day and already ran out of credits, glad I got the context persisted using SpecKit and CLAUDE.md, switching from @OpenAI Codex to @AnthropicAI Claude Code for rest of the day ....

[Arun Gupta @arungupta]

@brunoborges @bbenz Other tools allow that too. But what role does Copilot play in this? What's the value add?

[Arun Gupta @arungupta]

AI coding works great… until you switch agents. That’s where context breaks, and everything gets reinterpreted.

I used SpecKit with a simple project-level governance & CLAUDE.md to enforce behavior.

Agents became interchangeable, hand-offs worked https://t.co/UaSJgrd2a7

"Our primary instrument may be dying, but our job is not dying. It is being elevated."

I've been living in Claude + Codex and a dumb editor like VS Code to review the code. That's been sufficient.

[Arun Gupta @arungupta]

@brunoborges @bbenz If I’m using Claude or Codex, what’s the purpose of CoPilot? Adding another layer?
