Fastest GPT yet?

gm legends, happy Friday.

GPT 5.3 Codex Spark is the hit-the-gas mode for coding inside Codex, Typeletter gives you a quiet corner to write actual letters instead of more posts, and Atomic Bot turns OpenClaw setup on your Mac from “ugh, later” into a one-minute click job

GPT 5.3 Codex Spark is a smaller, ultra fast version of GPT 5.3 Codex built for real time coding inside the Codex app, CLI, and VS Code. It runs on Cerebras hardware with more than 1000 tokens per second, has a 128k context window, and is tuned for quick, targeted edits rather than long agent runs. It is rolling out as a research preview to ChatGPT Pro users with separate rate limits while OpenAI scales up capacity.

🔥 Our Take: There has been a lot of talk about agents that think for minutes or hours before you see anything. This update is clearly for the other kind of developer, the one who wants to nudge code in small steps, interrupt mid stream, and keep moving without staring at a spinner. I am very interested to see how many people keep this as their everyday default and only reach for the heavier model when they really have to.

Nika started a thread after seeing a post that OpenAI is projecting a 14 billion dollar loss for 2026 and reading about how big tech is pouring huge amounts into AI while investors are starting to sweat.

She is basically asking two things: how people think OpenAI will realistically make up those losses, and whether this level of spend means we are in an AI bubble that could pop. Underneath that is a bigger question she throws to the community: could OpenAI actually lose its spot at the front if the money, or the mood, shifts.

Typeletter turns your browser into a simple space for writing letters, journal entries, or thoughts without logins or setup. It mimics a typewriter with clacky keys and a classic layout, lets you pick ink colors and ambient sounds like rain or jazz, and when you are done you can send it as an email or save it as a stamped image or time capsule for later.

🔥 Our Take: There is a quiet charm here if you miss writing things that are meant for one person, not a feed. No streaks, no stats, just a page, some noise in the background and an excuse to actually finish a thought before you tab away.

Atomic Bot is a macOS app that gets a local OpenClaw agent running in about a minute. You skip terminal setup, Docker, and dependency puzzles, everything runs on your Mac so your workspace stays on your machine, and you plug in your own LLM API keys through a simple UI. It is open source and free to use.

🔥 Our Take: OpenClaw already has fans who are happy to wrestle with setup. Plenty of people are not. A tiny Mac app that handles that and keeps everything local makes it way easier to share with friends instead of only the one person on the team who enjoys fighting config.
