Workers - Run Workers for up to 5 minutes of CPU-time

You can now run a Worker for up to 5 minutes of CPU time for each request. Previously, each Workers request ran for a maximum of 30 seconds of CPU time — that is the time that a Worker is actually performing a task (we still allowed unlimited wall-clock time, in case you were waiting on slow resources). This meant that some compute-intensive tasks were impossible to do with a Worker. For instance, you might want to take the cryptographic hash of a large file from R2. If this computation ran for

PlanetScale vectors is now GA

After a winter of focused development, we are excited to announce that PlanetScale's support for vector search and storage is GA. Since the open beta began, we have doubled query performance, improved memory efficiency eight times, and focused on robustness to ensure vector support is as solid as every other data type MySQL supports. We are especially proud of the scalability of vector indexes, which now perform well even when they are 6x larger than available memory. It's a real relational inde

Introducing 4o Image Generation

At OpenAI, we have long believed image generation should be a primary capability of our language models. That’s why we’ve built our most advanced image generator yet into GPT‑4o. The result—image generation that is not only beautiful, but useful.
