Claude Fable 5 will be available again globally tomorrow.
After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8. We’ll continue to refine these classifiers over the coming weeks to reduce false positives and better distinguish genuine misuse from legitimate requests.
We’ve also begun drafting a consensus framework—with Amazon, Microsoft, Google, and other Glasswing partners—for assessing the severity of AI jailbreaks and how AI developers should respond to them. We invite other industry partners and model providers to join us in this effort.
Finally, we’re scaling up our collaboration with the US government on model testing and safeguards. This will include pre-release access to models and safeguards for evaluation, information sharing on jailbreaks and misuse, and dedicated resources for joint research.
Thank you to our users for your patience, and to our partners across the government, industry, and the research community who worked alongside us to make Fable 5 available again.

We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We'll begin restoring access tomorrow, and will share an update soon.
We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.
Since June 12, we’ve been working closely with the US government to restore access to Claude Mythos 5 and Fable 5. Today, the government notified us that Mythos 5, our strongest cybersecurity model, can be redeployed to a set of US organizations that operate and defend critical infrastructure.
We’re restoring access for these organizations quickly, and we’re continuing to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again.
We have just done a 10 SOL buyback on $PROV. 20 SOL in total buybacks since launch and we will continue to do so.
Since launch we've hit 8,000+ verified proofs on @solana, grown to 1,800+ users, launched the API, integrated with @xona_agent, been accepted into @nvidia Inception, launched private vision AI, listed on the MCP Registry, and processed more on-chain verified AI inference than any other protocol.
Every message on Prova burns $PROV. Every API call burns $PROV. Every integration burns $PROV. As usage grows, the burns grow with it. We're supplementing that with direct buybacks from the team to support the chart while the protocol scales.
The team is here. The product is live. The roadmap is deep. We're not going anywhere - we're accelerating.

The numbers speak for themselves.
1,800+ users. 8,304 proofs verified on @solana. 16 open models, decentralized through 4 independent TEE networks. Every response hardware-attested by NVIDIA + Intel, cryptographically signed by the TEE, and verified on-chain by @solana.
No email collected. No identity stored. No prompts retained. Wallet-only from day one.
Every proof burns $PROV. Every proof is permanent on Solana.a

Today we're launching Private Vision AI on Prova - the first AI where you can upload sensitive documents and images, have them analyzed inside NVIDIA + Intel sealed hardware, and verify that privacy on @solana.
Think about what people actually put into AI every day. Not just text prompts. Medical scans. Legal contracts. Financial statements. Confidential blueprints. Tax returns. Private photos.
Every single one of those goes into a black box. No privacy guarantee. No proof of what happened to it. No way to verify.
Until now.
Every image and document uploaded to Prova is processed inside a TEE. The hardware signs it. Solana verifies it on-chain. A permanent, public proof that your sensitive data was handled privately - anchored to @solana before the proof is accepted.
We didn't build private text AI and stop there. The hardest privacy problem in AI is visual data - and we just solved it with on-chain proof.
Verified inference becomes more powerful when agents can actually use it.
With @AskProva live as a provider inside Xona Inference Marketplace, AI agents can now discover verified models, pay per request through @x402, and receive proof with every response.
Prova brings the verification layer.
Xona brings the commerce layer.
Powering commerce for AI agents on @solana.
The proof layer keeps growing.
1,140+ users. 2,876 messages - every single one hardware-attested by NVIDIA + Intel, cryptographically signed by the TEE, and verified on-chain by @solana. 16 models available across 4 independent TEE networks.
No email collected. No identity stored. No prompts retained. Wallet-only from day one.
Every message burns $PROV. Every proof is permanent on Solana. The protocol is live and growing.

Prova is now on the MCP Registry.
Any AI agent, any IDE, any framework that
supports MCP can now verify inference on-chain
through Prova. Claude, ChatGPT, Cursor, VS Code,
Copilot - all supported.
One install. Every response proven on @solana.
Get started:
npm install prova-mcp
