How to impress your valentine with Codex 💕 💡: @shhivanii IG

Say hello to GPT-5.3-Codex-Spark, our ultra-fast model purpose built for real-time coding. We’re rolling it out as a research preview for ChatGPT Pro users in the Codex app, Codex CLI, and IDE extension. GPT-5.3-Codex-Spark is the first milestone in our partnership with @cerebras. It provides a faster tier on the same production stack as our other models, complementing GPUs for workloads where low latency is critical. Codex will continue to get faster. We’ve optimized infrastructure on the critical path of the agent by improving response streaming, accelerating session initialization, and rewriting key parts of our inference stack. Codex-Spark is currently text-only with a 128k context window. We’ll introduce more capabilities–including larger models, longer context lengths, and multimodal input as we learn from our first production deployment of low-latency infrastructure and hardware. We’re giving a small group of API customers early access to Codex-Spark to experiment with it in their products, helping us continue optimizing performance beyond Codex and we’ll expand access to more ChatGPT users and API developers as we add more capacity.

What are you building with Codex?

You can just build things.

Introducing the Codex app—now available on macOS The Codex app is a powerful command center for building with agents. • Multitask effortlessly: Work with multiple agents in parallel and keep agent changes isolated with worktrees • Create & use skills: package your tools + conventions into reusable capabilities • Set up automations: delegate repetitive work to Codex with scheduled workflows in the background Available starting today on macOS with Windows coming soon. And for a limited time, Codex is available through ChatGPT Free and Go subscriptions—and we’re doubling rate limits for Plus, Pro, Business, Enterprise, and Edu users—across the Codex app, CLI, IDE extension, and cloud.

As AI begins to meaningfully accelerate scientific discovery, we’re taking an early step to reduce friction in day-to-day research work. Introducing Prism—a free workspace for scientists to write and collaborate on research, powered by GPT-5.2. We’re excited to learn from researchers using Prism today and to continue building toward tools that help science move faster — together. Prism is now available on the web to anyone with a ChatGPT personal account.

ChatGPT Go is rolling out globally in every country where ChatGPT is available. ChatGPT Go is our low-cost subscription tier that gives you 10x more messages, file uploads and image creation vs free tier. Also more memory, longer context window, and unlimited use of GPT 5.2 instant for $8 USD/month.

Need a more personalized workout routine? ChatGPT Health is a dedicated space in ChatGPT that allows you to securely connect electronic medical records and wellness apps like Peloton, Apple Fitness, and MyFitnessPal to discuss what works best for you with the whole picture. We’re rolling out to a small group of users first so we can learn and improve the experience, and plan to expand to everyone on web & iOS soon.
