Today we're announcing that Modal has crossed $1B in annualized run rate, as well as raised a $750M Series D at a $15.75B valuation, led by @Accel. Since our Series C, usage has tripled and we’ve grown more than 15x year-over-year. We are deeply grateful to the developers and companies building on Modal. There's still so much more to build, and we can't think of a better time to be building software.

I GET TO WORK WITH THIS GUY @nanjiangwill 🐐
Training large models with RL typically runs on a fixed homogeneous cluster of the latest accelerators for numerical stability and faster throughput. This throws away inference optimization work done for other vendors and generations, limits the capacity you can utilize, and is unnecessarily expensive. So we trained a model on agentic coding tasks using fully asynchronous RL and mixed-precision, mixed-accelerator samplers. With off-policy correction, training stayed stable through convergence, on par with homogeneous samplers, at a lower cost.

DFlash: Keep Drafting Parallel My talk at @modal Runtime in SF on Oct 1. The drafter was the serial bottleneck, so DFlash made it parallel. That moved the bottleneck to selection, so DFlash 2 fixed that.
DFlash 2 is here! Qwen3.8-27B at 70 tok/s on an M5 Max MacBook Pro. ⚡ Up to 4.6× the speed of autoregressive decoding, with the same output. This is the next generation of DFlash, seeded at Z Lab and upgraded at Inco AI. Get one more accepted token on every pass, for free! inco.ai/blog/dflash2/

apparently I have 8 commits in sglang but I’ve been slacking since my last one was mid June
which of your favorite token brokers are contributing back to open source ai? shall we count the ways? a slice of data: number of PRs upstreamed and merged into the most popular oss inference engines, by PR contributor org

modal 💚 sglang! grateful for our collaborations so far, and many more to come!
It was a pleasure to work through the nights together with @modal on the Kimi K3 support! Now it's time to try it out 😁

DFlash to the moon(shot)!
Kimi K3 is live on Modal. Moonshot has shipped the world's first open 3T-class model, and we're a day zero launch partner. We trained a custom DFlash speculator for K3's novel architecture so you can run it faster, losslessly. The most capable open model we've worked with by far.

Frontier models require frontier speculators. Our team moved mountains to achieve 460 tok/s with our custom DFlash model. Try it day 0 at modal.com/endpoints.

Inkling by @thinkymachines is now available on Modal, backed by a custom DFlash speculator for 67% higher throughput and interactivity. Running on Modal Auto Endpoints with SGLang today.
Today, we are introducing Inkling. Inkling reasons efficiently across text, image, and audio modalities. We are making the full weights available. thinkingmachines.ai/news/int… Available today for fine-tuning on Tinker. Play with it in the Inkling Playground. 🧵

As always, it’s a lot more nuanced than this. In spec decoding, the predominant cost is target verification, the chain vs tree tradeoff is well known, and at production concurrencies you’re often better off training a better draft model than doing tree drafting.
I want to bring your attention to JetSpec because it looks strictly smarter and stronger than previous speculative decoding and block diffusion approaches (yes, again). Avg 1000 t/s single stream with Qwen-8B on B200. Basically, you can better utilize compute at any batch size.

Try them out! 🚀 Really enjoyed the amazing collaboration with the Modal team. The retrained DFlash draft models now support longer contexts, making them a better fit for agentic workloads.

🚀 New blog: The next generation of speculative decoding: DFlash and Spec V2 DFlash + Spec V2 hit >4.3X baseline throughput for LLM inference, now the default speculative decoding engine in SGLang! Together with @modal and z-lab.ai, our jointly-released DFlash drafter for Qwen 3.5 397B-A17B beats both baseline and native MTP in every setting we benchmarked: 1️⃣ >4.3X baseline & 1.5X native MTP throughput (concurrency 1, HumanEval, 8xB200) 2️⃣ Block diffusion drafter: a full token block in one forward pass 3️⃣ KV injection: target-model features fed into every draft layer’s KV cache for higher acceptance 4️⃣ Spec V2 overlap scheduler: +33% end-to-end Read the code, deploy a DFlash server, and start experimenting!
