Two things to pay attention here. Cerebra’s can only run a small version of GPT5.3, because why else would they run only a smaller model?

Also, where is gpt-5.3-codex on azure? Opus 4.6 is available since the launch in both azure and google vertex. Codex is nowhere to be seen.

I love this! I use coding agents to generate web-based slide decks where “master slides” are just components, and we already have rules + assets to enforce corporate identity. With content + prompts, it’s straightforward to generate a clean, predefined presentation. What I’d really want on top is an “improv mode”: during the talk, I can branch off based on audience questions or small wording changes, and the system p…

You're describing almost verbatim what we're building at Octigen [1]! Happy to provide a demo and/or give you free access to our alpha version already online. [1] https://octigen.com

Claude Code is pretty good at making slides already. What’s your differentiator?

As an associate professor who spends a ridiculous amount of time preparing for lectures, I would love to try this in one of my courses

Try Claude Code too. It’s surprisingly good at this.

First thoughts using gpt-5.3-codex-spark in Codex CLI: Blazing fast but it definitely has a small model feel. It's tearing up bluey bench (my personal agent speed benchmark), which is a file system benchmark where I have the agent generate transcripts for untitled episodes of a season of bluey, perform a web search to find the episode descriptions, and then match the transcripts against the descriptions to generate f…

I gave it a run on my Astro website project. It definitely makes more mistakes than Codex-5.3, but the speed is something to behold. The text flashes by way faster than I can understand what's going on. And most of its edits worked. I then used Codex-5.3-xhigh to clean things up...

Wow, I wish we could post pictures to HN. That chip is HUGE!!!! The WSE-3 is the largest AI chip ever built, measuring 46,255 mm² and containing 4 trillion transistors. It delivers 125 petaflops of AI compute through 900,000 AI-optimized cores — 19× more transistors and 28× more compute than the NVIDIA B200. From https://www.cerebras.ai/chip : https://cdn.sanity.io/images/e4qjo92p/production/78c94c67be9... https://cd…

There have been discussions about this chip here in the past. Maybe not that particular one but previous versions of it. The whole server if I remember correctly eats some 20KWs of power.

20KW? Wow. That's a lot of power. Is that figure per hour?

It’s 20kW for as long as you can afford the power bill

If you run it for an hour, yes.

I know it's an AI company, but once again, stop writing PRs with chatgpt. I actually read the whole thing and it was mostly repetitions about how the model is fast and how they partnered with cerberas and the model has speed, and cerberas helped with the model, and the latency is low and this is a collaboration with Cerberas.

I can literally feel how the 50 word prompt butter is spread over the 2000 word bread.

If you run it for an hour, yes.

I asked because that's the average power consumption of an average household in the US per day. So, if that figure is per hour, that's equivalent to one household worth of power consumption per hour...which is a lot.
