Day 25/ We are doubling all usage limits for all Pro 100/200/500 tiers and Business Premium, effective today. We heard your kind feedback and wonโ€™t be reducing usage limits for Pro 200, so your Work and Codex usage will stay the same. Weโ€™re also going to continue offering extended limits for dots for now, and usage of your dot will still continue to be separate from your default usage. And we'll of course also keep shipping better models and other efficiency improvements that increase your effective usage over time.

We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a personโ€ฆfull of emotion, nuance, pauses, and a natural cadence. block.xyz/dessa

The Optimum team is pleased to announce our first mainnet deployment, mump2p on Ethereum. With mump2p, data moves across all of Ethereum 2-3x faster, boosting validator performance and network health. $3.4B of Ethereum stake is already being boosted by mump2p, and weโ€™re now opening up free access for all Ethereum node operators.

Today the EF and OA announce zkAPIโ€”a new means for private AI Picture this: deposit ether into a vault, sign a zk proof, get a fixed amount of private inference. Advances like these help us move past middlemen's requirements that we link our data and identities. Read more below
Quick updates on the Open Anonymity project (@OpenAnonProject)! 1. OA-chat is live! You can now signup: chat.openanonymity.ai 2. We collaborated with @ethereumfndn (@VitalikButerin, @DavideCrapis, @VittoStack, @curryrasul) to develop zkAPI, a new zero-knowledge protocol for accessing gated / paid APIs with unlinkability. Itโ€™s like a generalization of OA unlinkable inference that also abstracts payments away. Now also available on OA-chat! I'm excited because more infrastructure should exist where privacy and sovereignty is foundational and people are in control.

We can probably get 8 second slots and 2-3 minutes finality by early 2028 already, if we play our cards right and get faster slots done in Hegotรก. Letโ€™s get a fast cryptographic world computer!
THE BLOCK: Vitalik Buterin says Ethereum is called a "blockchain" mostly "for historical reasons" and is turning into a "cryptographic world computer." Buterin projected slots of 4 to 8 seconds by 2030, and finality in 8 to 32 seconds in a new blog post.

Reminder: you can now sync an ethereum node within half a day and with aggressive settings the space it takes up on disk can be under half a terabyte. EIP-4444 and hard work by client teams on optimizing snap sync has improved things *a lot*. Glamsterdam will improve the sync situation further still (eg. Nimbus's new sync protocol uses it)
