These are a few of my favorite sf hills, in no particular order.
1. Hawk Hill - the rougher sister to the well known Grand View Park. Drops off absurdly steep overlooking outer sunset.
Aaron Boodman@aboodman
Hey SF people - Iโm not sure who needs to hear this but... Feeling down? Anxious? Go outside. Walk uphill. At every decision point, choose uphill. You will soon find yourself at an empty park with a lovely view. SF is *littered* with these hilltop parks. There are dozens. Long ago, the top of almost every hill in the city was set aside as open space. You can spend your entire SF career exploring them and never run out. It was often the only thing keeping me sane. They are a wonderful resource that Iโm constantly surprised nobody knows about.

Thank you so much to everyone in Japan for noticing GlagStone.
Iโm really happy to see people reacting to my 1-bit game.
Iโll keep working on Japanese localization.

These indie devs are making a game where you can play in 2D and 3D at the same time!
- The world's first 5D platformer
- Solve puzzles by shifting perspective
- Some things only exist in one dimension
It's called Screenbound. Would you play this?

@SharingPsyche @HeyGarrison @SharingPsyche any more info you can offer on where (cloud provider, local, etc.) you were running, and what model/provider, so we can investigate? We aren't doing any explicit batching/chunking.
English
@HeyGarrison last time i checked vercel ai-gateway batches output streams of tokens so you get "chunky" output.
Direct model providers did not seem to have this issue.
As far as benchmarking goes it would be pretty hard to determine if it was ai-gateway or the underlying provider.

Use Vercel Sandbox with the OpenAI agents SDK as an official extension.
Build agents that can run code, read files, and analyze data safely inside isolated microVMs. Control the compute and data flow from your secure cloud environment.
OpenAI Developers@OpenAIDevs
Build long-running agents with more control over agent execution. New capabilities in the Agents SDK: โข Run agents in controlled sandboxes โข Inspect and customize the open-source harness โข Control when memories are created and where theyโre stored

3 months ago I started building a coding agent that runs in the cloud.
It's since written every line of code I've shipped, including itself.
Today, I'm open sourcing it. Introducing Open Agents.

Today we're open sourcing open-agents.dev, a reference platform for cloud coding agents.
You've heard that companies like Stripe (Minions), Ramp (Inspect), Spotify (Honk), Block (Goose), and others are building their own "AI software factories". Why?
1๏ธโฃ On a technical level, off-the-shelf coding agents don't perform well with huge monorepos, don't have your institutional knowledge, integrations, and custom workflows.
2๏ธโฃ On a business level, the moat of software companies will shift from 'the code they wrote', to the 'means of production' of that code. The alpha is in your factory.
Open Agents deploys to our agentic infrastructure: Fluid for running the agent's brain, Workflow for its long-running durability, Sandbox for secure code execution, AI Gateway for multi-model tokens.
(Because of our focus on Open SDKs and runtimes, this codebase is a gem even if you're not hosting on Vercel.)
TL;DR: if you're building an internal or user-facing agentic coding platform, deploy this:

If you are building AI Agents using @aisdk, you must be familiar with this pattern of storing conversation history after each turn of the conversation and loading it back into the agent's context before each turn. This is the standard pattern for maintaining the state of agent sessions.

Vercel Sandbox is now the #1 fastest microVM-based Sandbox.
Weโve also heard from customers migrating that beyond โin the labโ benchmarks, our real-world performance & reliability are second-to-none. Literally.
Whether itโs ๐ฆ claws, coding agents, or plain compute parallelism, we think this is the foundation of the new world. Enjoy!
Malte Ubl@cramforce
Vercel Sandboxes are now the fastest sandbox using real VMs as security boundary based on the @computesdk benchmark. The team has been absolutely cooking on this. And the best thing: Because we have a unified Fluid Compute stack across Sandbox, Builds, and Functions these wins are often shared across the stack. On the feature side there is a really exciting roadmap ahead as well. My favorites (all driven by feature requests from our customers): - Persistent sandboxes (in beta, GA immanent) - The fully mutable firewall also becomes fully programmable

AI Gateway now supports team-wide Zero Data Retention (ZDR).
Building safely with multiple AI models means wrestling with fragmented data policies, per-provider negotiations, and the hope that developers do not use non-complaint providers.
AI Gateway changes this with team-wide ZDR.
Gateway ensures your data requirements are automatically met by only routing to providers where we have negotiated ZDR agreements.
Instead of managing policies provider by provider, you get one unified data policy across Claude, GPT, Gemini, and many more providers.
Toggle it on in your dashboard, and all requests will route safely without touching any code:
โข Team-wide ZDR
โข Per-request controls
โข Disallow prompt training
Move compliance to the gateway so your team can keep shipping โ

Builders are voting with traffic.
This week, Novita is ranked #7 among the top AI providers on Vercel AI Gateway, alongside leaders like Anthropic, OpenAI, and Google.
What makes this exciting isnโt the ranking itself.
Itโs what it represents:
more developers are choosing fast, production-ready inference infrastructure for the shift from models to agents.
Weโre proud to be part of the stack powering that transition.
More to build. More to scale.

As a former big-tech guy I couldn't be more proud that big-tech runs on Vercel now. Kudos to Meta for paving the way!
The velocity wins of running on Vercel are no longer optional, even if, or especially when you have 20+ years of sunk-cost-fallacy infra in your mega monorepo
Guillermo Rauch@rauchg
The best outcome for humanity is many strong AIs competing for the top spot. Vercel is proudly powering meta.ai and the infrastructure that made today's model release possible.
