How do these ruins relate to the past and present? Who or what remains inside? Why would anyone go there? 

This update brings a new homepage to AI Realm, making it easier to return to your adventures, browse your favorite worlds, and reach your creation tools. You’ll also find the latest patch notes there, so you can keep up with what’s changing.

We’ve added Discord sign-in, a dedicated inventory image manager, and a redesigned AI model menu to help you compare models and choose one for your play style. Campaign sharing lets others read along with your adventures, while guide syncing helps you bring updates from a world package into an existing campaign.

Alongside these features, we’ve improved multiplayer controls, image generation, mobile layouts, and character sheet customization. Read on for the full list of additions, improvements, and fixes on our new patch notes page!

Our new homepage!

Hey everyone!

We were aware of the outage that Muse has had since yesterday and now know why Meta Muse is down. Turns out that we might've violated some of Meta's guidelines and they've blocked our API endpoint for both the Contributor and the regular Muse. We're working on restoring access but in the meantime, both Muses will be unavailable. We do not have an ETA for when access will be restored.

While at it, I kindly remind everyone to be reasonable about what you send to the AIs and follow our site usage guidelines.

We apologize for the inconvenience and thank you for your patience.

Beginning a weekly Question of the Week series to help encourage some discussions amongst you all!

Which societies no longer exist in your world?

Who were they? Why did they disappear? What did they leave behind? How do these societies continue to influence the present? Has the world ever been more advanced than it is now? Are there any surviving remnants of these societies?

We’ve rolled out several new features, quality-of-life improvements, and multiplayer fixes!

Favorite Shared Worlds

You can now favorite shared worlds, making it easier to keep track of the ones you enjoy most.

Share your Chats

You can now generate a "share link" to give your fellow gamers a read-only version of your game, to show off your hard work, or to share a cool scene. Revoke the shared access at any time.

Better AI Model Sorting & Filtering

We’ve added new sorting and filtering options to make finding the right AI model easier. You can now:

- Filter by provider

- Filter by model strengths

- Sort by user ratings

- Sort by model cost

Expanded AI Model Selection

As always, all available AI models can be used for single-player chat - that hasn’t changed.

What’s new is that your model selection is now available across even more actions:

- Single-player editing

- Single-player regeneration

- Multiplayer chat

- Multiplayer generation

This gives you much more control over which AI model is used throughout both single-player and multiplayer experiences.

Multiplayer Improvements

We’ve also made a small collection of multiplayer improvements, including:

- The ability to kick users

- The full selection of AI models is now available in multiplayer

- Several security fixes and improvements

GM Guide Syncing

You can now sync the state of your GM Guides with the world package your chat was created from. Choose from several sync options to control how your guides are updated.

Thanks for being part of the community, and we hope you enjoy the improvements! 🎉

If you have DeepSeek V4 Flash selected on AI Realm, you are using V4.1 flash. V4 pro still routes to V4 pro and once that changes, we will offer V4 pro at a higher price or lower context boost starting the 14th.

Let us know how good or bad the new model is in the comments!

Hey everyone! A highly requested update just dropped. Here's everything new:

🤖 8 New AI Models

The model roster just got a lot bigger:

• Kimi k3 — Moonshot's newest model (4 Premium Messages)

• Muse Spark 1.2 — New model from Meta (4 Premium Messages)

• Muse Spark 1.2 (Data Sharing) — Discounted Muse Spark with a +40% context bonus! (1 normal message — conversations may be used by Meta to improve their models)

• Gemini 3.7 Flash — The newest Gemini Flash (2 Premium Messages)

• Gemini 3.5 Flash Lite — Fast and lightweight (1 normal message)

• GPT-5.6 Luna — New OpenAI model with a +30% context bonus (1 normal message)

• Hy3 (Hunyuan 3) — New Tencent model with a +40% context bonus (1 normal message)

• MiniMax M3 — New model from MiniMax (1 normal message)

Look for the red NEW badge in the model selection screen!

📏 NEW FEATURE: Context Expansion

Ever hit the "Context Size Exceeded" wall? Now you have options:

• Every model card now has an edit button (top-left corner) to open its Context Expansion settings

• Expand a model's context limit by +50% or +100% for an increased premium message cost per response

• You're only charged the higher price when your context actually exceeds the free limit — stay under it and you pay the normal price

• ⚠️ Heads up: AI models get less accurate/intelligent at very large context sizes, so we still recommend keeping your notes trim when you can. The Context Size Exceeded popup now includes a handy dropdown with tips for reducing your context!

💎 New Premium Message Bundles

Two new one-time purchase bundles with bonus messages baked in (never expire!):

• 2,050 Premium Messages — $24.99 (2,000 + 50 BONUS) ✨ Better Value

• 4,200 Premium Messages — $49.99 *(4,000 + 200 BONUS)* 🔥 Best Value

• The classic 800 for $9.99 is still available

⚖️ Pricing Adjustments

• Gemini 3.1 Pro: 6 → 8 Premium Messages (small increase because of bad cache percentage)

• Qwen 3 Max: 1 → 2 Premium Messages

• Imagen 4 has been retired from the image generator options

Let everyone know what you think of the models!

I would recommend trying out Meta's Muse Spark 1.2 (Data sharing) if you don't mind your conversations being used for training. Otherwise try out GPT-5.6 Luna or Gemini 3.7 Flash.
