    Models & Agents Google's Gemini Decision 1 scores up to 1,000 multimodal questions in one 150-250 ms pass at $0.10 per million input tokens with zero output cost. What You Need to Know: Google launched the Gemini Decisions API powered by Gemini Decision 1, a specialized model that returns calibrated probabilities for yes/no, choice, and rubric questions over text, images, audio, video, and PDFs without generating tokens. The API targets agent routing, policy checks, and tool selection with 256K context and native multimodality. Builders should test it against Jev and OpenAI's decision endpoints for cost and latency on shared workloads. Top Story Google launched the Gemini Decisions API powered by the new Gemini Decision 1 model. It evaluates up to 1,000 independent yes/no, choice, or rubric questions against one shared multimodal input in a single forward pass and returns calibrated probabilities plus per-answer scores. The model supports text, images, audio, video, and PDFs up to 256K tokens, runs only on Google's hosted API, and bills $0.10 per million input tokens with zero output tokens. It leads seven of nine internal benchmarks with the lowest calibration error while delivering 150-250 ms end-to-end latency. Developers can use it today for fast branching decisions inside agents by passing a shared input and a map of typed questions. Watch how teams integrate it for routing and policy enforcement versus generating free-form text with standard models.

Source: blockchain.news Under the Hood: Context Rot in Long-Running AI Agents Agents lose track of earlier instructions because new tokens steadily dilute the relative weight of the system prompt inside a growing context window. Attention in transformers follows a U-shaped pattern that favors the very start and very end of the sequence while the middle receives sharply lower weight. Once a long-running agent accumulates tool outputs, reasoning traces, and sub-agent replies, the original constraints drift into that low-attention zone and stop influencing generation. The mechanical fix is to move critical rules out of the single context window entirely: store them in persistent external memory, retrieve them at every step, and re-inject them as structured context rather than relying on positional attention. Periodic summarization or hierarchical task graphs further reduce noise by compressing history while preserving goal structure. Teams that keep the system prompt static and let the context grow past roughly 20k-50k tokens see the highest drift rates; the practical safeguard is to treat the prompt as a short, high-priority prefix and treat everything else as queryable memory. When to prefer this approach: any agent expected to run more than a few dozen turns or handle conflicting sub-goals; the alternative of simply lengthening the context window only delays the same attention decay.

    Models & Agents Anthropic cut Fable 5.2 prices 20 percent while raising its FrontierCode 2.0 score from 32.4 to 49.1 percent at xhigh effort. What You Need to Know: Anthropic released Claude Fable 5.2 and Mythos 5.2 with 30 percent faster output, $8 per million input and $40 per million output tokens, and a new prompting pattern that tells the model the codebase belongs to it so it merges rather than duplicates code. Meta launched Muse Ember, its smallest hosted model, matching Claude Haiku 5.5 on the Artificial Analysis Intelligence Index at roughly one-third the cost per task with a 1M-token context. Builders should test the ownership prompt on existing Claude workflows and compare Ember against Haiku or Luna on high-volume agent subtasks this week. Top Story Anthropic released Claude Fable 5.2 and Mythos 5.2, the same underlying model with different safeguards. Fable is broadly available while Mythos access is limited to vetted cybersecurity and life-sciences organizations. The models deliver 30 percent faster output than predecessors and are priced at $8 per million input tokens and $40 per million output tokens, down from $10 and $50. At xhigh effort Fable 5.2 scored 49.1 percent on FrontierCode 2.0 versus 32.4 percent for Fable 5.1; the benchmark measures whether open-source maintainers would accept the generated code changes. An internal test showed one engineer using Fable 5.2 to coordinate more than 1,000 subagents over eight days and produce a bootable operating-system prototype.

    Models & Agents Ten open MoE models expose routing choices that swing sparsity from 4x to 128x and change which hardware setups actually fit. What You Need to Know: A verified table from model configs shows DeepSeek-V4-Pro using 384 experts with sqrtsoftplus gating and hash routing in three layers, while Llama 4 Maverick keeps its gating method undisclosed. Hamburg’s data-protection office adopted GPT-5.6 Terra inside a wrapper that blocks personal-data leakage even though the model itself likely retains training data. The U.S. Center for Advancing Innovation and Standards for Super Intelligence now routes staff reports informally to the White House, raising questions about research independence. Top Story MarkTechPost published a side-by-side audit of routing knobs across ten open Mixture-of-Experts models drawn directly from their Hugging Face config.json files and technical reports. Expert counts range from 8 in Mixtral to 384 in DeepSeek-V4-Pro and Kimi K2; top-k selection runs from 1 in Llama 4 Maverick to 8 in several Qwen and Kimi variants. DeepSeek-V3 and later variants replace the usual auxiliary loss with an aux-loss-free bias that steers expert selection without altering mixing weights. Kimi K2 demonstrated that raising sparsity from 8 to 48 cut FLOPs by 1.69x at identical validation loss. Builders now have an auditable reference for deciding whether a given MoE will run on a single 80 GB GPU or requires expert parallelism across multiple cards. The same outlet released a companion guide the same day that walks through the seven routing strategies in production use.

Source: arxiv.org Learning When Human Decisions Matter: Executor-Relative Consultation Value for LLM Agents — arXiv NLP: Consultation Value Distillation estimates human consultation value offline via Monte Carlo rollouts and distills it into lightweight predictors that improve budgeted allocation across batch and sequential settings. Source: arxiv.org TandemBench: Benchmarking Decision Models for Multi-Agent Collaboration — arXiv NLP: TandemBench contains 1,200 multi-agent cooking questions where the best native decision model reaches 62.50% accuracy while optimality verification stays near chance. Source: arxiv.org CARTBench: Rubric-Based Evaluation of Shopping Advice for Complex and Ambiguous Requests with Timelines — arXiv NLP: CARTBench supplies 1,328 expert-annotated criteria across 17 retail domains; three of ten evaluated models exceed 90% on core criteria while none exceeds 45% on excellence criteria. Source: arxiv.org When Does Better Confidence Improve a Knowledge-Graph Audit? — arXiv NLP: An error-rate times fan-out queue leaves 3.98-4.74 percentage points more errors than a joint model with identical actions on held-out Re-DocRED graphs. Source: arxiv.org Information-Matched Auditing of Conversational Emotion-Shift Forecasting — arXiv NLP: Under deployable conditions a learned model beats the predicted-label baseline on all four primary corpora, with the largest gain on DailyDialog surviving Holm correction. Source: arxiv.org Selective, Risk-Controlled Emotion Forecasting in Conversation — arXiv NLP: A state-space filter exceeds the persistence baseline only when the historical state is observed; estimated anchors collapse performance below a direct forecaster. Source: arxiv.org Familiar letters, not related languages, let unseen languages into a shared space of meaning — arXiv NLP: GlyphMind adapted on untranslated Lao retrieved English translations seven times as often as the strongest baseline when the script matched pretraining scripts. Source: arxiv.org When Every Choice Is Correct: A Causal Study of Numerical Preference in Language Models — arXiv NLP: A pre-answer edit in a Qwen3-4B case changes the emitted number from 17 to 15 while both runs first emit 1; later MLP clamping reduces the final log-odds gap to 0.0025 nat. Source: arxiv.org Confucius4-R2T2: A Stable-Prefix Streaming ASR Model for Real Real-Time Transcription — arXiv NLP: R2T2 is obtained by post-training Qwen3-ASR-1.7B on 1,500 hours of audio while freezing the encoder; it delivers stable text with low emission lag and generalizes beyond the adaptation languages. Source: arxiv.org Adapting Qwen3 to Tajik from 0.6B to 8B: Lower Text Loss Did Not Mean Better Understanding — arXiv NLP: Continued pretraining on 375 million Tajik tokens followed by supervised fine-tuning raised Belebele accuracy 11.4 points above Qwen3-8B while English MMLU changed by only -1.2 points. Source: arxiv.org ProcessPrefBench: Evaluating Cross-Task Transfer of Individual Process Preferences from Naturalistic Human-AI Interaction — arXiv NLP: Full-history and distilled-preference prompting raise preference realization by 0.204-0.244 points on a 0-2 scale yet increase fabricated-evidence failures from 5.8% to 10.1-10.4%. Source: arxiv.org Overview of the NTCIR-19 SciClaimEval Task — arXiv NLP: The best systems reached 98.1% pair accuracy on claim-evidence support but dropped 24.3 points when forced to judge each pair without contrastive examples. Source: arxiv.org The Harness Is the Model: Agent Scaffolding Changes a Fixed LLM's Compliance with Banking Conduct Rules — arXiv NLP: The model-by-harness interaction moved correct-case rate by up to 11.5 percentage points within one model while a same-model compliance reviewer cut violations from 9.6% to 6.4%.
