Beam is now available across platforms, with open weights under the Apache 2.0 license - in collaboration with an ecosystem of 40+ partners.
We're releasing:
- Weights, tokenizer, and reference implementation
- BF16, FP8 and NVFP4 weights and a DFlash2 drafter
- The open source harness we built and trained Beam on: Mirror CLI

This afternoon, Senate Democrats proved they were never truly serious about protecting consumers and preserving American leadership. I sat at the table with Senate Democrats working in good faith to get this done while they played games.
For over a year, they presented demands and the second we met them, they made new demands and moved the goal posts. Today they voted against real limitations on politicians’ personal crypto investments. They voted against protecting American consumers from the scammers and fraudsters this bill would have shut down. They voted against American leadership, and handed China and every one of our foreign competitors exactly what they wanted. Democrats chose politics over the American people—again. That’s not leadership on their part, that’s surrender to their radical, socialist base.
The once-proud Democratic party is anti-consumer and pro-illicit finance, anti-ethics, anti-free enterprise, anti-worker, anti-livable wage jobs, and pro-socialism. The Democrats are now anti-American. Sad!
I expect @reflection_ai will lead the charge in US-based open models. Coming soon…
For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.
AI will transform every industry, power every company, and be built by every country.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.
The world needs both frontier closed models and frontier open models.

Access to intelligence should not depend on a handful of companies or governments.
This is why open, decentralized, permissionless AI matters.
This is why Bittensor matters.
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

Today, we announced that the SEC has declared the Registration Statement on Form S-4 effective. The proposed business combination will be submitted to $CEPT shareholders of record as of May 11, 2026 (the "Record Date"), for approval at a special meeting scheduled for June 29, 2026, and, if approved, is expected to close shortly thereafter. Upon closing of the transaction, the combined company is expected to operate under the name Securitize Corp., and its shares are expected to trade on the NYSE under the ticker symbol "SECZ."

General Tensor & Talisman are partnering to make Bittensor effortless — for institutional capital, retail users, and the agents working for them.
@generaltensor × @wearetalisman 🦋
Pairing one of the network's largest wallets with a production grade multi-sig solution, across the GT stack, including @BackpropFinance, and @Rubicon_Bridge
Custody. Trade. Cross-chain. One vision.

Excited to share that we’ve raised $300M in our Series B round, led by @radicalvcfund, bringing our total funding to more than $450M, with leading technology companies joining as both customers and investors.
We continue accelerating the path to AGI through our two core pillars: ultra-optimized infrastructure for AI workloads, and realtime world models built on top of it.
Today, we’re also launching DOS (Decart Optimization Stack) 2.0 – our next-generation inference and training platform, delivering over 1,600 tokens per second for agentic inference and over 100 FPS for world models across major hardware platforms.
Alongside DOS, we will launch new versions of our world models in the coming weeks: Lucy, for immersive realtime experiences, and Oasis, for physical AI.
Grateful to our partners, customers, and backers across media & entertainment, Physical AI, chips, hyperscalers, and the broader AI ecosystem.
@radicalvcfund, @Adobe, @alphaptrs, @amazon and @awscloud, @Atreidesmgmt, @benchmark, @eBay, @nvidia, @sequoia, @Toyota, @valor, @orenzeev; Andrej Karpathy, Michael Eisner, Yamauchi-No.10 Family Office, Moritz Baier-Lentz and more.
We made a film for this moment with Decart CEO @DLeitersdorf and Moritz Baier-Lentz - a look at the company, the technology, and what comes next.

Every milestone has been leading to this.
We're proud to announce that General Tensor has acquired Backprop Finance from @TensorplexLabs.
@BackpropFinance is the all-in-one trading terminal for Bittensor subnets - and is one of Bittensor's highest-volume trading platforms, accounting for up to one-third of the network's subnet volume annualized.
The next chapter starts now.

The amount of things happening at @Securitize right now is insane:
- tokenized stocks w/ @JupiterExchange x @jumptrading on @Solana
- @NYSE partnership for tokenized stock trading
- @Computershare partnership for tokenized issuance
- @FINRA approval for fullstack IPO infra
There's one company in the list that seems out of place among these hyperscalers — @reflection_ai — but it’s not.
The company is building the leading open-weights model in the U.S., expected to be comparable (or even superior) to the Chinese models.

Today, the @DeptofWar entered into agreements with SEVEN of the world's leading frontier AI model and infrastructure companies to deploy frontier capabilities on the Department's classified networks:
• SpaceX
• OpenAI
• Google
• NVIDIA
• Reflection
• Microsoft
• Amazon Web Services
This is just the latest initiative in our mandate to create an AI-FIRST WAR DEPARTMENT 🇺🇸
