Never slept better and feeling reseted. Brand new me and brand new usage for all ChatGPT Work and Codex users. Regaining my youth one button press at a time. Happy Thursday

Introducing Gemini 3.5 Transcribe, our new speech to text model with smart transcription, function calling, more precise transcription (lower WER), custom vocabulary support, multi-speaker identification, and support for over 85 languages! Also with realtime streaming support! https://t.co/5xUmKmc4OY

Model Architecture Four core upgrades for maximum capability, efficiency, capacity, and stability: - Attention: GDN + QSA Hybrid. Gated DeltaNet (GDN) compresses history. Qwen Sparse Attention (QSA) uses a lightweight indexer for micro-block context selection. Lower the cost of attention on long sequences. - Residual: Gated Residual (GR) widens the residual stream to 4 branches with a dynamic read and write gating, strengthening cross-layer information flow and significantly improving training stability. - Embedding: N-gram Embedding uses local context lookups to expand model capacity at minimal compute cost, while keeping the embedding table in host memory with asynchronous prefetching. - Optimization: Muon optimizer. Refines Muon through improved orthogonalization, smarter parameter assignment between Muon and AdamW, and fused-parameter splitting, with scaling laws refitted for the new architecture.

Claude now has one memory across chat and Claude Cowork, and you decide what's in it. Hand Cowork a task and it starts from what Claude already knows from your chats: the project you talked through, your manager's preferences, or the client from last quarter. https://t.co/ViKapsT8K6

Portable Computer runs a post-trained and locally installed PPLX 27B model. Qwen 3.8 27B is also available, with support for NVIDIA Nemotron 3.5 Lightning coming soon. https://t.co/2t2S3pU3ff

Tomorrow we will bring back the 5h limit for Plus accounts across ChatGPT Work and Codex. I had mentioned this a while ago, but then postponed it. This is necessary as (a) the 5h limit allows us to smoothen the load on our compute, allowing to keep the plan generous in terms of weekly usage and (b) users on the Plus plan are relatively casual and new users, but then also just accidentally eat through their whole weeks usage and then are confused, making it not a great experience. We are for the upcoming months keeping the 5h limit not enabled for Pro $100 and Pro $200 subscriptions.

Supported by Asana, Atlassian, Canva, Datadog, Figma, Granola, Linear, Notion, Slack, and Supabase. Developers can also add enterprise-managed auth to their own third-party MCP connectors in the Claude directory. Blog: https://t.co/vPhSthb6go Docs: https://t.co/XbsRhyXIT5

SpaceX, in partnership with Nvidia, has designed a space-optimized Vera Rubin NVL72 system for launch to orbit in Q4 next year, with significant scale in 2028 https://t.co/qdDq8YBkzl
