Another model joins the Mercury lineup.
More choice for developers, without changing the way they work.
Keep building. We'll keep expanding what's possible.
New model drop!
MiniMax M3.1 Flash is now available in Mercury Agent.
Fast, lightweight, and ready to plug into your workflow, without changing how you work.
Switch models. Keep shipping.

No API keys? No problem. 😎
Your AI agent doesn't need to wait for one.
With Mercury Cloud, access AI models without bringing your own API keys, connect your agent, and manage it all from one cloud workspace.
Your next move? Create your workspace.

Security incidents are never easy, especially while they’re still unfolding. Appreciate the transparency and the prompt notification to affected users.
Hope the team can contain this quickly and come back stronger. User security comes first.

This is good use of JEV. Mercury Agent has this in built and local
The future of AI agents isn't about relying on a single model.
It's about bringing different capabilities together to solve real-world problems.
Another step forward for Mercury Agent.
New model drop in Mercury Agent
NVIDIA: Nemotron 3.5 Super VL (FREE) is now available.
Vision understanding.
Multimodal reasoning.
Built for real-world tasks.
Try it in Mercury and put it to work.

Good to see Grok recognize what we’ve prioritized from day one with Mercury Agent.
Security, user control, and privacy aren’t optional features. They’re fundamental to how we build AI agents at Cosmic Stack.
And we’re just getting started.
Hey @grok, let’s settle this. Remove the secure harness from the list.

Congratulations.
Soon going to be available on our Mercury Cloud.

This is exactly what we love about open source. Someone gives a new project a real shot, finds rough edges, and contributes seven PRs to make it better.
Really appreciate the support and honest feedback!

Congrats to the Fish Audio team! Incredible work on Drama 3. The expressive control and open weights are impressive.
We’re excited to bring this into Mercury Agent. Great work, team!
Replying to @0xsmerkzz
Interesting to see this approach gaining traction.
We’re exploring the same direction with Mercury Bots, where persistent agents have their own roles, memory, and permissions. Lots of potential here.
One agent is useful. A team of specialized agents is a different game.
Mercury 1.3.0 introduces Bots, persistent specialists with their own roles, memory, and workflows.
Built by the Mercury team at Cosmic Stack.

Meet Mercury Code.
A senior software developer-grade AI agent, built directly inside Mercury Agent.
Open Mercury.
Type:
/code
And start building.
Mercury Agent v1.2.3 is live ↓
Great open-source projects deserve more than stars. They deserve a fair shot at support, visibility, and real opportunities.
This is just the beginning.
Open source is full of great projects that never get the attention, support, or opportunities they deserve.
That’s why we’re launching Open Contest, in partnership with Cosmic Stack.
Think Y Combinator for open source, combined with a global competition built around real developers and real projects.
No pitch decks.
No long applications.
No need for thousands of GitHub stars.
Whether your repo has 20 stars or 20,000, what matters is what you’re building, the problem it solves, and the potential behind it.
Selected projects will get access to a growing mix of opportunities, support, visibility, resources, connections, recognition, and more as the program evolves.
If you’re building something open source, we want you to have a fair shot.
