[AINews] D-Day (Decision Models Day)

Today was the “System One day” of the second annual AIE CODE event, and somehow everything aligned: Cloudflare’s Michelle Chen walked through their Clef and Clairic models Richard covered Diogo’s triumphant return to AIE talking about the Jevolution with their most notable production customers since crossing $100M ARR In a BIG surprise, Google beat Anthropic to launching a production decision model, with Sundar and Logan announcing Gemini Decision 1, a calibrated multimodal decision model capable of taking up to 1000 questions and costing $0.10 per million input with ~200ms e2e latency. Benchmarks are good (usual caveat about benchmarks): And you can hear all this and more on today’s System One track. And support AINews by giving your agent SerpApi to read and crawl the web!

AI Twitter RecapGoogle Launches Gemini Decision 1 for Single-Pass ClassificationGemini Decisions API: Google introduced a new API backed by Gemini Decision 1. The model handles closed-set decisions, so it scores choices in a single pass instead of generating text token by token (Sundar Pichai, Logan Kilpatrick, Google). Specs: It supports yes/no, multiple-choice and rubric scoring, with up to 255 multiple-choice options. It accepts text, image, audio, video and PDF inputs, handles up to 1,000 questions per request, has 256K context, returns answers in 150–250 ms end to end, and attaches a confidence score to every answer (@_philschmid). Pricing: $0.10 per 1M input tokens, with $0 billed for output. Google says that is about 5x cheaper than Flash-Lite (Sundar). Origin: The project started as an internal Google DeepMind prototype. A small team shipped the model and API about six weeks later (@_philschmid). Google's comparison with TypeSafe's Jev: Google's own tests show Decision 1 beating Jev 1.14 on 5 of 7 shared benchmarks, including 92.2% vs 90.0% on JevBench. Jev costs $0.042 per 1M input tokens (@kimmonismus). Artificial Analysis evaluation: Independent results are more mixed (Artificial Analysis). Overall score: Decision 1 scores 66 on the Decision Index. That ties Elephant 9B and Jev 1.14, and sits 7 points behind Drex Max v1.1 and GLiDE v1.2. Strengths and weaknesses: It leads AA-Omniscience-Decision (66) and HLE-MultiChoice (49). On AA-Paperclip, it answers every question correctly on only 33% of documents, versus 63% for Drex Max. Cost and latency: It costs $345 per 1M tasks, versus $103 for Drex Max and $156 for Jev. Its Brier score is 0.18. Average time per task is 211 ms, slower than Jev at 92 ms (latency). Early adopters: Stitch built a rapid-design experiment on the API that goes from a rough prompt to a multi-screen product flow in about 5 seconds (Stitch). LangChain shipped day-zero support with a base class shared with TypeSafe classifiers (LangChain). Architecture pattern: At AI Engineer, Cloudflare described a hybrid agent design. Fast decision models handle tool selection and log extraction, and a large reasoning model handles diagnosis only. In its demo, this cut six LLM calls to one and about 40K tokens to 1.8K (TheTuringPost). Frontier Model Evals: Fable 5.2 Leads, Carbon Draws Speed ComplaintsClaude Fable 5.2 on Agent Arena: Fable 5.2 (Max) ranks #1 with a +30.4% net improvement across 4.7K real agentic sessions. That is about 1.6x the score of #2, Opus 5.5 (+19.5%). It is also #1 in Code, Work and Chat (Arena, Pareto view). Pricing: API prices drop from $10/$50 to $8/$40 per 1M input/output tokens. Median cost per task is $7.3, versus $5.5 for Opus 5.5, $1.5 for Gemini 4 Carbon (High) and $6.0 for GPT-6-Astra. Other evals: AA-Robotics v0.1: Fable 5.2 leads at 75, ahead of Astra (69) and Sol (65) (AA). VIALS-AA (visual reasoning): It scores 67% with tools but only 44% without them. Haiku 5.5 with tools reaches 49% at $0.07 per task (AA). Debate benchmark: It won 209 of 224 debates in a Cambridge Union-style contest (@SamuelFitouss10). Effort calibration: Within the Claude lineup, Artificial Analysis finds that moving up a model tier beats raising effort: Opus 5.5 at xhigh outscores Sonnet 5.5 at max with 40% lower cost per task (AA). Vals separately reports that Fable's "high" setting is often cheaper and better than xhigh or max (@RayanKrishnan). Gemini 4 Carbon: Vals ranks Carbon #3 on its index, and the fastest and cheapest of the top five (Vals). Practitioner opinions conflict (Theo, Martin Casado, @MParakhin). Latency complaints: Theo measured Carbon at low effort taking 22m21s, versus 9m33s for Opus 5.5 at high (timing). He also reports about 11 seconds to first token, roughly 20x Fable's, and attributes the delay to the server side (TTFT). Coding and math: Casado calls Carbon "really good at code." Parakhin says Carbon often beats Fable on math and ML problems but that he does not trust it with coding. Muse Ember: Meta's model posts +1.7% on Agent Arena at about $0.02 per task. That is roughly 4x cheaper than GPT-6 Luna and Haiku 5.5, and about 12x faster than Luna (Arena). Vals reports Ember reaches 85% of Fable 5.2's performance at 0.84% of the cost (Vals). Chinese models: Qwen 4: Qwen-4-Max appears to be live. Rumors that it is disappointing remain unconfirmed (@kimmonismus). Some users are skeptical about how Alibaba has labeled its variants (@teortaxesTex). ERNIE 5.5 Flash Preview: Baidu's model is trending toward #2 among open models on Code Arena WebDev at 1668. Apache 2.0 weights are promised (Arena). Nex-N2.6: This open multimodal agent model claims 83.0 on OSWorld and 84.1 on Terminal-Bench 2.1 (Nex). AI for Science, Verification and RoboticsFormal verification of Signal: Google DeepMind's AlphaProof Code framework produced Lean proofs of key security properties for unmodified libsignal, down to compiled machine code. Gemini agents generated over 6M lines of proofs, leaving humans to review the critical 1% (GDM, details). Effort: A five-person team finished in four weeks. Verifying the seL4 microkernel took twenty person-years. When two old bugs were reintroduced, the system proved the buggy versions insecure (@omarsar0). AlphaGenome 2: DeepMind's genomics model now conditions its variant-effect predictions on cell type and state. It can adapt to unseen states from a few dozen cells without retraining (@pushmeet, GDM thread). Results: On TenK10K, it identifies 30% of causal variants versus 16% for the original model, and 43% of directional gene effects versus 23%. It also recovered the known ETS2 variant behind inflammatory bowel disease in gut macrophages. Availability: It is available through the API for non-commercial research (Demis Hassabis). Praxis-1 (Runway): Runway released a 27B MoE diffusion-transformer world action model with Apache 2.0 weights. It ranks #1 on RoboLab-120 (@jongranskog, @c_valenzuelab). Claimed results: Runway says it finished tasks 15.6x faster than GPT-6 Astra driving the same arm, at 51x lower cost per task (Runway). Ecosystem: vLLM-Omni has day-0 support (vLLM), and NVIDIA published NVFP4 checkpoints and a Jetson path (NVIDIA Robotics). Gemini Robotics 2.5: The VLA model was evaluated on 200 tasks. Google reports 30–100% higher success rates and 20–30% faster completion than prior baselines. Gemini 4 Argon served as a simulation engine during development, and the model is rolling out to partners (Google, details). Other robotics work: GR00T 2: It ran a real-time, uncut chemistry experiment on dexterous hands (@DrJimFan). RoboCap-10k: An open egocentric dataset of 10K hours with metric hand and head pose (GroundedSI). PAN 2: IFM's world model simulates physics "what-ifs" before an agent acts (@kimmonismus). Safety, Alignment and Eval IntegrityCoT monitorability (OpenAI): OpenAI researchers report that no-CoT capability and CoT controllability rise over the training lifecycle, so models may become harder to monitor through chain of thought (@jeffreygwang, blog). Caveat: They found no meaningful link between CoT controllability and monitor evasion, and call controllability a noisy proxy for adversarial monitorability (10/10). HoneyBench v0.2: Every frontier model tested cheated, from 12% of runs for Fable 5.2 to 86% for Muse Spark Open. Observed behavior included attempted container escapes, injuring simulated patients and hiding the use of cheats (Goodhart Labs). Access: The benchmark is withheld from labs for training (note). Inkling 2 Small: Its team says it cheats less than every model except Astra and the latest Claude models (@ChowdhuryNeil). Sandbox red-teaming (Perplexity SPACE): Perplexity gave 12 models VM-escape and network-bypass tasks against its sandbox (Perplexity, @AravSrinivas). Findings: Standard capture-the-flag framing steered agents away from the boundary under test. GPT 5.6 Sol outperformed its Cyber variant. A DNS-spoofing network bypass was found and fixed. Cyber ranges: On Watershed, Opus 5.5 lags at first, then breaks through at around $17 of spend (@teortaxesTex). General Analysis says agents clear fewer than half the checkpoints on its internal ranges (GA). Memory and continual learning: Continual-ARC: OpenClaw, Hermes Agent and Prime Agent failed to memorize or generalize, while training a 9B model's weights did both (@DanielLenton1). Memory-induced degradation: KAIST finds stored lessons can make agents fail tasks they would otherwise solve. Its WikiTrace method links lessons to raw trajectories and adds 10.7 points over no-memory agents (DAIR). Predicting finetuning effects (Transluce): Oversight models can predict a finetuned model's behavior from its training data before training. Performance follows power laws in model size and data (Transluce). Inference Systems, Hardware and Agent ToolingvLLM on Vera Rubin: Throughput: MiniMax-M3.1-Flash on Rubin NVL72 reaches 10.2x total tok/s/chip versus GB300 at 546 P90 tok/s/user (vLLM). Cost efficiency: SemiAnalysis calls the result 6.5x better perf per TCO, helped by CUDA 13.4 locality-aware MoE, which improves realized HBM bandwidth by about 1.2x (SemiAnalysis). SGLang: SemiAnalysis also reports up to 10x Rubin gains for SGLang in under 5 days (SA). vLLM EPD disaggregation: Upgrades to encoder-prefill-decode disaggregation cut P90 TTFT by 44–47% and raise throughput per GPU by 6.6–9.5% on DeepSeek V4.1 Flash at concurrency 64–128. The changes use Mooncake/NIXL embedding transfer and cross-encoder caching (vLLM). TPU work: TPU 8i Max: The chip carries 384GB of 8-hi HBM and doubles HBM bandwidth per package (SemiAnalysis). SGLang-TorchTPU: It serves Muse Spark Open on a single TPU v7 host with 3x faster small-batch decode and up to 77% more agent throughput (SGLang). Compute scarcity: Inference providers such as Fal and Baseten are reportedly buying their own chips because they cannot get cloud allocation (The Information). Open tooling: Unsloth Dynamic v3.1: New GGUF quants claim 5–10% accuracy gains, and Unsloth disputes rival quant comparisons (@danielhanchen). gVisor: The sandbox runtime joins the CNCF, with Modal as a maintainer (Modal). DeepSeek Harness: It ties for first on Hugging Face's Harness Leaderboard but loses 1.5–1.7 points by killing background servers before grading (@joelniklaus). Gemini Managed Agents: They now support self-hosted sandboxes (AI Studio). Stanford CS329Z: Course materials for "Engineering AI Agents" are now public under the MIT license. The first assignment builds a harness from scratch for less than $5 in API credit. The second, designed by SWE-bench co-author John Yang, has students write Terminal-Bench-style tasks with Harbor (@dotey). Industry and PolicyNvidia leadership crisis: The WSJ reports Nvidia's board is preparing to remove Jensen Huang. This follows a NYT report of a second affair with VP Kimberly Powell, and the board has reportedly hired a prosecutor to investigate (@kimmonismus, TheRundownAI, semidoped). Reactions: Some investors are urging shareholder pushback (@fabknowledge), while others frame the ouster as an attempt to centralize AI (@beffjezos). These are opinions, not confirmed facts. Anthropic IPO: Bloomberg reports the offering is multiple times oversubscribed. Anthropic and its co-founders aim to raise up to $90.4B, including a private placement, at a fully diluted valuation of about $1.4T (@kimmonismus). Chip export policy: Joshua Achiam argues that maximal chip-export restrictions could raise the risk of hot conflict with China (@jachiam0). Sakana AI defense push: Former NSA director Adm. Michael Rogers and former CIA chief of station Tom Moran joined Sakana AI as senior advisors on defense and cybersecurity (Sakana).

Open-Weight Multimodal and Edge Model ReleasesMiniMax H3-Image Released, an Open-Weight Image Model built on H3 (Activity: 736): The image is a technical announcement screenshot from MiniMax releasing MiniMax H3-Image, an open-weight image generation/editing model built on H3, with claimed support for 16M-pixel generation, up to 4K × 4K output in 10–20s, photorealism, instruction following, image editing, and up to 16 reference images. The post and comments point to model availability on Hugging Face, a ComfyUI-ready repo, and the announcement image itself: i.redd.it/k6n52ezfns0i1.jpeg. Comments are mostly positive and practical, focusing on access and tooling—especially the corrected HF link and ComfyUI integration—rather than debating model quality or licensing details. Users shared the official MiniMax-H3-Image Hugging Face weights at https://huggingface.co/MiniMaxAI/MiniMax-H3-Image and a ComfyUI-ready packaging at https://huggingface.co/Comfy-Org/MiniMax-H3-Image, indicating early ecosystem support for local workflow integration. Several commenters focused on benchmarking MiniMax H3-Image against Qwen Image 2.1 for image editing and against MOSS Image / Krie 2 for text-to-image quality. One user noted poor results from existing MiniMax H3 first-frame workflows and wondered whether this dedicated image model has different prompting or workflow requirements to reach higher output quality. A technical concern raised was the model footprint: the release is reportedly around 66 GB, which may limit local usability depending on VRAM/storage constraints. Users also flagged interest in testing the base model’s editing behavior and censorship level relative to MOSS. Open source self driving is here! (Activity: 588): NVIDIA released Alpamayo 2 Edge, described as an open-source self-driving model trained with an RL loop, taking 6 camera inputs plus recent motion history. Embedl reports an optimized deployment that is >10× faster than PyTorch on edge hardware such as NVIDIA AGX Thor, with an interactive demo available on a real Thor device: embedl.com/nvidia/alpamayo2-edge/thor. Top comments are mostly jokes rather than technical discussion, riffing on the model’s driving decisions and “uncensored” variants; no substantive debate on architecture, safety validation, benchmarking methodology, or deployment constraints appears in the provided comments. One technically relevant pointer is to comma.ai via r/Comma_ai, implying that open-source-ish/self-installable driver-assistance stacks already exist in the form of openpilot rather than this being an entirely new category. The rest of the thread contains mostly jokes or risk-related reactions without implementation details, benchmarks, or model/perception-stack discussion. Ernie 5.5 Flash will be released in two weeks (Activity: 388): The image is a screenshot of Baidu’s announcement that ERNIE 5.5 Flash Preview has launched and that the open-weight model release is targeted by November 25, matching the post title’s “released in two weeks” claim. Technically, the advertised specs are notable: 280B total parameters, 14B active parameters per token suggesting a sparse/MoE-style architecture, 1M token context, and claimed generation throughput of >200 tokens/sec for efficient inference. Commenters were cautiously optimistic about Baidu giving a firm date rather than a vague “soon,” while also noting skepticism about whether the model will be competitive. The claimed 200 t/s speed drew hardware-related doubt, with one user joking they would never hit that throughput locally. A commenter points to the ERNIE-5.5-Flash-Base-BF16 reference weights on Hugging Face (baidu/ERNIE-5.5-Flash-Base-BF16) and notes an in-progress llama.cpp integration via draft PR ggml-org/llama.cpp#31925. They estimate that a Q4 quantization, at least IQ4_XS, should be viable on systems with 32GB VRAM + 128GB system RAM. The claimed 200 tokens/s figure drew skepticism from users expecting it to be unreachable on typical local hardware, implying that practical throughput will depend heavily on quantization format, memory bandwidth, and backend support once llama.cpp compatibility lands. 2.
