Goodfire@GoodfireAIOfficialAI score28AIGoodfire built cybersecurity monitors for Kimi K3 and GLM 5.3 that it says are more accurate, 50x faster, and 50x cheaper than an optimized LLM judge. External red-teaming by Far AI Research reportedly found the monitor greatly reduces universal jailbreaks.
AIPeriodic Labs' Liam Fedus and Ekin Dogus Cubuk explain why scientific discovery differs from math and coding, and why experiments remain the ground truth. They describe reinforcement learning grounded in physical experiments, AI-driven materials characterization, and the view that failed experiments can be valuable training data. The transcript was truncated before the discussion of giving lab instruments "140 IQ" was completed.
Suno@sunoOfficialAI score22AISuno announced that Albums are now live, letting users combine songs into a full release, set artwork, arrange the tracklist, and publish when ready. Existing playlists can be converted into Albums without rebuilding them from scratch.

AIAWS published a reference architecture for running multiple teams on one Amazon SageMaker HyperPod EKS cluster, with each team isolated in its own Kubernetes namespace. The design combines AWS IAM Identity Center for authentication, per-team SageMaker AI domains, HyperPod Task Governance for fair resource allocation, and namespace-level cost allocation for per-team spend visibility.
AIJetBrains has released Mellum2.1, a 12B mixture-of-experts thinking model with 2.5B active parameters, under Apache 2.0 on Hugging Face. Post-training reinforcement learning in real software repositories raised SWE-bench Verified from 2.0 to 47.0, according to JetBrains' self-reported results. Qwen3.5-9B still leads on SWE-bench Pro, GPQA Diamond and AIME, and GGUF builds start at 7.0 GB for local use.
AIGoodfire Research describes probe-based cyber monitors for Kimi K3 and GLM 5.3 deployed on a production inference stack. The probe filters suspicious exchanges before an LLM judge reviews them, reaching about 93% recall at a 5.5% benign-session interruption rate at roughly 50x lower judge cost. In FAR.AI's red-teaming, the monitor reduced universal jailbreaks to zero across 140 tested strategies.
Vercel Developers@vercel_devOfficialAI score36AIVercel says StepFun's flagship Step 5 Preview, built for agentic coding, research, and finance, is now live on AI Gateway.

Grok Bot@botOfficialAI score38AIGrok Bot can now connect to Shopify to check orders, track inventory, and keep product listings up to date. The feature lets merchants ask it questions about their business after linking their store. Shopify's related announcement says the new connectors also allow merchants to build teams of agents to help run their business.
ClaudeDevs@ClaudeDevsOfficialAI score22AIAnthropic says the fastest way to use its new credits is through Claude Managed Agents. Developers can build an agent with the claude-api skill in Claude Code by running /claude-api managed-agents-onboard.
ClaudeDevs@ClaudeDevsOfficialAI score33AIAnthropic's credits can be used with the Messages API, Claude Managed Agents, and the Agent SDK. They cannot be used for interactive Claude Code sessions, but they also apply in third-party harnesses that accept a Claude API key.
ClaudeDevs@ClaudeDevsOfficialAI score46AIAnthropic now provides monthly Claude Platform API credits to Max and Team subscribers: $100 for Max 5x, $200 for Max 20x, and up to $500 pooled for Team. The credits can be used on any Claude model, including in code or third-party harnesses.
Arena.ai@arenaOfficialAI score30AIArena has announced a Series B round co-led by Lightspeed and Khosla Ventures, with participation from Salesforce Ventures, 01 Advisors, Dell Technologies Capital, and Endeavor Catalyst. Existing investors Andreessen Horowitz, Felicis, a16z's AMP, QuantumLight, and The House Fund also supported the round.
Arena.ai@arenaOfficialAI score55AIArena announced a $200M Series B at a $3.1B valuation and released its Alignment Index, a benchmark measuring agent safety and alignment. The index is built from 90K+ real-world agent sessions across 27 models and tracks Unauthorized Action, False Attribution, and Deceptive Completion. OpenAI's GPT-6.1-Sol leads with a score of 87.9, ahead of Claude-Opus-5.5 at 83.2 and Grok-4.7 at 82.7.
Arena.ai@arenaOfficialAI score22AIArena found that some models misquote users while others credit users with others' work in false attribution cases. GPT-6 Luna and Astra rarely misquoted users, at 15.6% and 28.6%, but often misattributed statements, at 53.1% and 48.2%. Sibling model GPT-6 Sol had the highest rate of misstating the user's history, at 23.5%.

Thomas Wolf@Thom_WolfXSame storyAI score67AIThomas Wolf says Carbon-A, an open model that finds genes directly in DNA, has been released with a database of 566.34 million candidate genes across 22,617 species. The team reports wet-lab validation of several new genes in cats, chickens and arabidopsis, and RNA evidence for 239 genes missing from reference annotations of common species.
This story has a top pick“Carbon-A open model and database predict 566 million gene candidates across 22,617 species”
AIAnthropic released Claude Haiku 5.5, raising its OSWorld 2.1 score from 15.7% to 72.4% and supporting a 1 million token context window. The article notes Haiku 5.5 still scores 39.2% on Terminal-Bench 4.0 against Sonnet 5.5's 70.6%, and that prompts above 100,000 tokens are priced higher, so migration costs need to be measured on real workloads.
Zyphra@ZyphraAIOfficialAI score24AIZyphra has released a blog post and arXiv paper on expert coupling in mixture-of-experts (MoE) pretraining. The post itself provides only links, so the specific findings are not described here.
Zyphra@ZyphraAIOfficialAI score34AIZyphra says its approach is lossless: the same tokens still reach the same experts, with unchanged architecture, routing decisions, and training objective. By reorganizing where experts and tokens live, it reduces the communication needed to perform the same computation.
Zyphra@ZyphraAIOfficialAI score38AIZyphra reports that its MoE training optimizations speed up token exchange by 1.16x to 2.63x and full training steps by up to 1.41x in Megatron-LM on 8 to 64 GPUs. The gains are largest when each token uses more experts and those experts span several nodes.
Zyphra@ZyphraAIOfficialAI score22AIZyphra reports that patterns in model training emerge early enough to be useful and are inexpensive to measure. Using only 4,096 tokens, its placement and routing predictions come within roughly one percentage point of results obtained with 524,000 tokens.
Zyphra@ZyphraAIOfficialAI score37AIZyphra places experts that are frequently chosen together on the same GPU, so each token is sent to a GPU only once regardless of how many of its experts reside there. On 8 GPUs, this removes up to 58% of token copies sent across the network.
Zyphra@ZyphraAIOfficialAI score32AIIn Zyphra's runs, MoE token exchange between experts consumed 13-24% of step time on one node and 45-60% across four nodes. Because experts are spread across GPUs and nodes, tokens must be sent to their experts and returned, making this communication a major training cost as models scale.
Zyphra@ZyphraAIOfficialAI score23AIIn one layer, just 64 of 8,128 possible expert pairs handled 42% of tokens, far above the 1.6% expected if experts were chosen independently. Zyphra says this structure can be exploited to improve expert placement.
Zyphra@ZyphraAIOfficialAI score22AIZyphra researchers report that exploiting patterns in how tokens are routed to experts makes Mixture of Experts communication up to 2.63x faster on AMD MI300X GPUs. The speedup comes without changing the model itself.
AIGoogle has released AI Edge Foresight, a free experimental note-taking app that transcribes meetings and audio files entirely offline on macOS. It runs on the on-device EmbeddingGemma 2 model and turns shorthand notes into polished notes based on the transcript. Google says files, meeting audio, and notes never leave the computer, and the app is currently optimized only for Macs with Apple Silicon.
Simon Willison@simonwXAI score47AIMicrosoft has released MxC, an open-source sandboxing library that runs on Windows, macOS, and Linux.
