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.

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 score12AIArena links readers to a full technical report on its blog and to a full rankings page in its Alignment Index. The post itself gives no model names, scores, or findings, so the substance is only in the linked materials.
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%.

Leandro von Werra@lvwerraXPickAI score70AICarbon-A is an open model that predicts gene locations directly from DNA, and it has been used to annotate genomes from over 22,000 species. The release includes a database of 566 million gene candidates, about 16 times the gene annotations in the RefSeq dataset. Wet-lab RNA experiments supported 239 candidates missing from RefSeq across cats, Syrian hamsters, chickens, and Arabidopsis.
Why it matters: The source ties an open gene-annotation model to specific wet-lab checks and gene counts, helping readers judge how far its predictions extend beyond well-studied genomes.

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 score18AIZyphra reports that expert routing in mixture-of-experts models is predictable across layers, since the experts a token uses in one layer indicate which it will need next. Its token shuffling method moves each token to the GPU holding those experts within a transfer that already runs after attention, adding no network traffic.
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.
