ChatGPT 5.4 can do real agentic work, but you still have to hold it at gunpoint to get the task done

@Jacobsklug @openclaw @VadimStrizheus I think the real struggle is getting this running without Claude OAuth and not spending 5000$/mo on API costs. And if you can't use Claude... then it really gets challenging... that said i can totally see this working with Claude.

@addyosmani This is awesome!

If your Kimi K-2 isn't blazing ahead, consider @ollama cloud. Man, what a difference.

@NTheEnigma In case you still haven’t got it working, please send us a message through the system, happy to help.

OpenClaw on the public internet is not a deployment. It's a liability.

That's why we built https://t.co/3j6l6SZO2U.

Private access. Zero exposure.

Tried MiniMax-M2.5 for OpenClaw agents expecting the usual budget tradeoff.

10-50x cheaper. Quality barely moved. Not what I expected...

[Lennert den Teuling @teulaert]

I don't get the OpenClaw skills security panic.

I just ask my Agent to build the skill I need. Takes 30 seconds. Tailored to my setup, and zero chance of malware.

The safest skill registry is no registry.

An AI agent that can message across Telegram, Slack, Discord, Signal and WhatsApp from a single conversation. No switching apps, no webhooks, no glue code.

@OpenClaw's cross-context messaging is criminally underrated.

[Lennert den Teuling @teulaert]

And yes, we did also got WhatsApp working through the UI so no terminal skills needed!

The best model upgrades don't announce themselves.

Opus 4.6 didn't feel different until I noticed I was correcting it less. Explaining less.

That's the real benchmark.

Serial work feels productive.

Parallel work is productive.

The aha moment isn't learning this concept with AI Agents.

It's realizing how much you've been leaving on the table.

"Is Claude Code getting worse?"
No. I just got lazy.
Garbage in, garbage out.

@karrisaarinen Ha! We’ve accidentally built this exact workflow over the past few months using Linear. 👍🏻

Our “aha” moment: When we connected Claude (Code) via MCP. Now, every workflow pulls context from Linear: issues, strategy, vision, goals.. you name it. It’s the single source of truth.
