Hey everyone, we have another big batch of updates to share with you all today. 

Kimi K3 is out of preview: We've spent the time since launch tuning the serving side, and K3 is now fully available for production workloads. Concurrency limits will ramp up over the next few days as our final validation completes. 

Flex now covers K3: Same deal as Flex on our other models -- if your workload can tolerate some timing flexibility (batch jobs, overnight runs) this is the most economical way to run K3. 

Anthropic Messages API and /v1/responses support is entering beta: If you've built against either format, you can point your existing tools at our endpoint and they'll run on Neuralwatt with the same energy visibility as everything else. We're opening beta access over the coming days as validation completes, so keep an eye out. 

Session View is live for everyone: Instead of account-level totals, you now get a session-by-session breakdown of exactly what you consumed. This is the most detail we've ever offered on your usage, providing a granular view of the requests you ran, the energy they used, and what they cost. 

Surge Protection: This one's new -- Surge Protection ensures you only pay for the energy that powers your work. From time to time, a request can draw more energy than the work it's doing should require. When it happens, Surge Protection catches it in real time and shields your usage from the excess. When it kicks in, you'll see it flagged in Session View, so you'll always know it stepped in. 

These updates will roll out over the next several days. 

Also, we're headed to NYC for Climate Week next month and are thinking about a meetup. Anyone interested? We have a poll coming; if enough of you are around, we'd love to see you.   

A handful of updates to share, which we think you will all welcome. Without further ado:  

 We’ve lowered cached pricing: Cached tokens now cost 10% of the input rate, down from 25%, on every model except DeepSeek-v4-Flash. If your work involves a lot of repeat context or if you are on token pricing, you should see a noticeable difference. 

Kimi K3 is now open to everyone: You no longer need to enroll for Kimi K3; access is now open for the entire Neuralwatt community. The model will remain in preview with limited concurrency while we keep tuning it, but access is open to everyone starting today.  We’re also releasing our K3 –flex endpoint which is our api shorthand for setting thinking level to off. 

DeepSeek-v4-Flash has been upgraded: You asked, and here it is! We rolled out DeepSeek-v4-Flash’s new 0731 weights this week, and it has already become our second most popular model —- no surprise given how many of you asked for it. All endpoints now point to the updated version automatically; there is nothing for you to change, and no action required on your end.  

Retiring Qwen 3.5 and Kimi K2.6: To free up capacity for the newer models, we're retiring Qwen 3.5 and Kimi K2.6. We'll redirect their endpoints to Qwen 3.6 and Kimi K2.7 so nothing breaks, but we'd recommend updating your code to point to the model you want before then. 

Enjoy the new additions; more soon. 

Hi all, Meaghan from the Neuralwatt team. There have been a lot of questions about K3, so wanted to share a note on where things stand. 

As you may have seen over in Discord, K3 arrives Monday, July 27, and assuming everything goes to plan, Neuralwatt will support it. We're working to make it available as close to release as possible, and we're actively expanding our GPU capacity to serve it. We'll post here as soon as we have a clearer picture of when it will be available. 

Because a model this size takes significant infrastructure to run well, access will open in stages: 

1. Pro (annual subscribers and highest-usage accounts) 
2. Standard 
3. Basic 
4. Pay-as-you-go

 

Capacity is a real constraint, so later tiers may take longer to open than any of us would ideally like. We are implementing this staggered approach to ensure K3 works smoothly at every level and for all. 

Additionally, this is by no means an attempt to push anyone to upgrade. While higher-tier plans will have earlier access, our goal is to make sure the entire community can experience K3 as quickly and seamlessly as possible. Nobody is going to be locked out, and nobody needs to change plans to get access. Pricing will also be published before each tier opens, so you can decide whether K3 is worth running before you commit. When your tier opens, the waitlist will hold your place and notify you when you have access. 

Lastly, K3's licensing terms are still being finalized, and broader external factors may still affect availability – this is something that we're monitoring. We'll post updates here as we get closer to launch and as each stage gets closer to opening.
