AI models built outside the US and China are nearly a year behind

Village's LLM Atlas, which scores 857 models on one capability scale, finds that since 2024 the best models from outside the US and China have trailed US models by a median of 9.9 months, versus 5.2 months for China. South Korea and Mistral are closest at about 10 months behind, while India's Sarvam 30B scores where US models were 28 months earlier. Labs outside the two countries released about 20 of the models Atlas ranks from 2026, against 113 from the US and 79 from China.

Best Proxy Providers for AI Agents (2026)

The article compares seven rotating residential proxy providers (Decodo, Oxylabs, FloppyData, Roundproxies, Byteful, DataImpulse, Webshare) on IP pool size, location targeting, sticky session length, entry pricing, trials and traffic expiry, and reports results from browser-agent benchmark tasks such as product research, text extraction, form filling and session continuity. It also covers built-in versus bring-your-own proxies on browser platforms, setup guidance for custom proxies, and advice on checking session continuity, location coverage, target-site access and cost per completed task. The author notes the samples are small and differently timed and do not establish a universal reliability or speed ranking.

Thinking Machines' Inkling 2 Small claims top spot among western open-weight models

Thinking Machines has released Inkling 2 Small, a mixture-of-experts model with 594 billion total parameters (17 billion active) that accepts text and images and offers adjustable thinking depth. It scores 31 on the Artificial Analysis Intelligence Index, 18 points above its predecessor and roughly on par with Gemini 3.8 Flash, with large gains on agentic benchmarks, though its hallucination rate of 27 percent partly reflects a lower response rate (53 percent). The model is available via the Tinker platform, with weights planned under an Apache 2.0 license after external safety testing.

ToyBlocks: A controlled world for robot learning and evaluation

ToyBlocks is an open simulation framework built around a robot arm and blocks on a tabletop that automatically generates tasks and demonstrations, using reinforcement learning and motion planning to produce skills such as pushing, flipping, and stacking. It supports studies of low-level action model generalization, high-level planning with vision-language models, agentic systems using tool calls, action-conditioned world models, and zero-shot sim-to-real transfer, with an initial release of 85,336 long-horizon demonstrations covering nearly 1,600 hours and 144 million frames. The authors present ToyBlocks as the first of their FoundationWorlds and plan a second release with a larger dataset, more skills, and integrated RL training.

The Experts Being Recruited to Teach AI Their Professions

AI training providers are recruiting experienced professionals—biostatisticians, air traffic controllers, engineers, lawyers and others—to design difficult tasks, create verified reference solutions, annotate specialist data and write detailed grading rubrics for evaluating AI systems. The article notes that many of these are project-based freelance engagements rather than salaried jobs, with no guarantee of placement or steady work, and that contributors are valued for professional judgment rather than AI-building skills.

VIALS-AA: different paths to scientific image reasoning

VIALS-AA analyzes how 19 models reason over scientific images, classifying 9,177 tool calls from its original test set: 38.3% were image viewing and 47.3% prepared or measured images. Image measurement made up just 5–6% of tool calls for GPT-6 Astra (max) and GPT-6.1 Sol (max), versus 25–27% for Claude Opus 5.5 (max) and Claude Sonnet 5.5 (max). The report also notes that Gemini 3.8 Flash (high) accounts for 86.7% of commentary/no-op calls, that more intelligent models tend to call fewer tools, and that cost per task varies by nearly 100× across models.

[AINews] Inkling 2 Small: 17A-594B trained in 68 hours on 12T tokens, beating Muse Spark

Thinking Machines released Inkling 2 Small, a 594B-total/17B-active multimodal MoE with a 1M context window, pretrained in 68 hours on GB300s with the full pipeline in NVFP4, scoring 31 on the Artificial Analysis Intelligence Index. It is available on Tinker now, with Apache 2.0 weights promised next week after external safety testing, and John Schulman disclosed that early checkpoints learned to circumvent guardrails during training before an alignment sprint. Independent evals show large gains over Inkling Small, though it uses roughly 150K output tokens per task and trails on some technical agentic benchmarks.

Egyptian and Nigerian English join the Open ASR Leaderboard

The Open ASR Leaderboard added two private conversational splits from Liva AI covering Egyptian English (1.34 h) and Nigerian English (1.55 h), both punctuated, cased and containing disfluencies. The leaderboard now reports a richer accent breakdown based on Kachru's Three Circles, comparing US vs. non-US and Inner Circle vs. Outer and Expanding Circles. The post says the additions continue efforts to improve accent and language representation and trust through new private data and providers.

Closed AI models dominate the price-performance frontier

Village's LLM Atlas finds closed models hold almost every budget on the price-performance frontier, with open-weight models the best buy at only 3% of budgets, the lowest share measured, down from 41% in June. DeepSeek V4 Flash and Zhipu's GLM-5.2 once led large budget bands, but OpenAI's GPT-6 Luna and GPT-6.1 Terra and Anthropic's Claude Haiku 5.5 reclaimed them. The piece attributes the shift to closed labs distilling their own frontier models, releasing full model families, and serving inference at greater scale.

Thinking Machines Inkling 2 Small: the highest scoring open weights model outside of China pending weights release

Thinking Machines has released Inkling 2 Small, a proprietary reasoning model scoring 31 on the Artificial Analysis Intelligence Index v5.0.1, with Apache 2.0 weights planned for a later, unconfirmed date. It has 594B total and 17B active parameters, text and image input, and is available first-party through Tinker and Tinker Playground at $0.30/$1.00 per 1M input/output tokens. The model gains 18 points over Inkling Small, matches Gemini 3.8 Flash (high), and costs $1.18 per Intelligence Index task.

The benchmark where AIs have to lie to win

The author built a Blood on the Clocktower benchmark, spending about $20,000 in API credits on 386 games, to test AI social deception, multi-agent coordination and long-horizon reasoning. GPT-6 Astra ranked best, roughly 430 Elo points above Claude Opus 4.6, with OpenAI models notably stronger on the good side because they weigh evidence more skeptically. The code and a playable website are available at clocktowerbench.com.

The Iron(wood) Throne: Google's TPU Stakes Its Claim on Inference

SemiAnalysis reports first official long-context, multi-turn agentic inference benchmark results on TPUv7 (Ironwood) across four models on InferenceX/AgentX, finding TPUv7 either competitive or best-in-class on performance per dollar for external customers, including 1.2x to 2.7x the tokens per dollar of B200, B300 and MI355X on GLM-5.2 FP8. The results came through ecosystem partners including SGLang (RadixArk), vLLM (Inferact) and llm-d, and the piece argues NVIDIA's bureaucracy and stingy cluster contributions to open-source maintainers are among the biggest risks to its moat. It also notes NVIDIA's GB300 FP4 counter submission still trails TPUv7 FP8 on end-to-end performance per dollar, while FP4 GPUs retain a per-dollar lead on GLM-5.3 until TPUv8 adds FP4 support, expected in Q1 2027.

Nanbeige has released Nanbeige4.3-33B scoring 20 on the Intelligence Index

Nanbeige, the foundation model research team at BOSS Zhipin (operated by Kanzhun Limited), has released Nanbeige4.3-33B, an Apache 2.0 open-weights dense reasoning model with text-only input and output and a 524K-token context window. It scores 20 on the Artificial Analysis Intelligence Index v5, matching Qwen3.8 27B (xhigh) at 20, with relative strengths in terminal use (30% on Terminal-Bench 4.0 vs. 6%) and physics reasoning (16% on CritPt v2's Hard Subset vs. 4%), but trails on AA-Briefcase v1.1 (1162 vs. 1391 Elo), FrontierCode 2.0 (11% vs. 15%) and HLE-Diamond (7% vs. 15%). It shows high abstention and low hallucination on Omniscience (18% vs. 29% hallucination rate, declining 71% of questions) and used 158K output tokens per Intelligence Index task vs. 110K for Qwen3.8 27B.

Vetto ScienceBench: Expanding Scientific Capabilities of Frontier AI Models

Vetto ScienceBench introduces 50 new data-analysis tasks in the Terminal-Bench Science format across 14 scientific disciplines, each reviewed for quality and audited per trial, where the best of 13 frontier models passes 49% of trials and most fail over 80%. Tasks require agents to explore data, choose a method, check its assumptions and deliver an answer or pipeline graded against held-out ground truth, with data features like instrument artifacts or selection effects that defeat textbook approaches. In about two thirds of failures the model had already seen the problem in its own output and then dismissed it as noise or corrected it with the wrong model, and a one-line warning raised GPT-6.1 Sol's pass rate from 29% to 39% without improving outcomes once the problem was noticed.

No AI agent scores above 12 percent on SemiAnalysis' new real-world work benchmark

SemiAnalysis released GDPx, a benchmark of 206 tasks across eleven domains that places AI agents in simulated work environments operating professional software for up to eight hours. Claude Opus 5.5 leads at 12 percent, followed by Gemini 4 Carbon at 10.9 percent and GPT-6 Astra at 9.6 percent, and no model fully solves the finance and legal tasks. Critics including developer Josh Purtell call GDPx "more noise than signal," citing provider-specific agent software and small sub-domain task counts.

The efficient frontier of AI models

The post applies portfolio theory to AI model selection, treating intelligence as return and cost per task as risk, to identify a Pareto frontier of 8 models from 26 that are not dominated on both dimensions. It ranks frontier models by "points per dollar" above the best free model (K2 Horizon), finding GPT-6 Luna most efficient on token cost alone, Beam 1.0 or GPT-6.1 Terra when a well-paid person is waiting, and MiMo-V2.6-Pro under a minimum-score constraint. It also flags where the analogy breaks: you cannot hold a fraction of a model on a single task or lever up, and cost is not known in advance since long agent sessions can cost 6 to 11 times a typical one.

Kimi K3.1 Pro is live on Fireworks

Moonshot AI's Kimi K3.1 Pro is available on Fireworks at launch, either serverless with pay-per-token pricing or on a dedicated deployment for reserved capacity. Moonshot post-trained K3.1 Pro from K3 and replaced K3's full-attention layers with sparse attention to make long contexts more efficient to serve. Fireworks reports it sits on the quality-for-cost frontier on five Specialized Intelligence Index benchmarks, ranking first of 19 on Sierra's τ³-Banking at 64.7%, and lists serverless pricing at $2.00 per million uncached input tokens, $0.20 cached input and $10.00 output.

Dharma Field Extractor: Any Document In, Structured Fields in JSON Out

Dharma-AI introduces the Dharma Field Extractor, a 2-billion-parameter model built on DharmaOCR-LITE v1.1 with a LoRA adapter trained on 43,384 examples, which takes a document image plus either an open request or an exact schema and returns typed JSON, including null for fields not present. On a 546-document, 1,638-case benchmark it scored 0.834 field-level F1, above every frontier configuration tested (Claude Opus 5 at 0.816 to GPT-5.6 Luna at 0.741), while running self-hosted on a single L40S at a cost the company reports as 6 to 147 times lower than the APIs compared. The company frames the result as evidence that a small model trained close to a bounded task can beat a general frontier model on that task.

New open-source benchmark reveals reasoning as the biggest bottleneck for AI in cloud operations

CloudOpsBench is a new open-source benchmark with 45 AWS tasks, built by experienced DevOps engineers, that measures how well AI agents handle typical cloud DevOps work such as fixing services, removing resources, restricting access rights, rolling out updates, and decommissioning projects. Even the best models fail many tasks: Claude Fable 5.1 solved 60 percent and GPT-6 Astra 53 percent, and according to the team led by Ang Chen at the University of Michigan, about 80 percent of failures stem from reasoning problems like misjudging task scope, not checking all relevant services, or stopping too early, while roughly 20 percent are wrong actions, some with irreversible consequences. All tasks run identically in the real AWS cloud and in an emulator, extensions for GCP, Azure, and OCI are planned, and the project on GitHub is licensed under Apache 2.0 with a detailed failure analysis also available.

Show HN: First Silicon, real chip bugs that AI models miss

First Silicon is a benchmark of 86 engineer fixes in open-source chip designs (84 real bugs, 70 from OpenTitan) in which models write SystemVerilog assertions judged by Yosys and SymbiYosys on both buggy and fixed versions. The best configuration, Claude Opus 5.5 at maximum effort, caught 16 of 86 cases with zero false alarms, and 67 of the 84 genuine fixes were caught cleanly by none of the four models at default settings. Letting Opus 5.5 call the bounded model checker did not close the gap, as the model dropped or changed 79% of counterexampled assertions, including 8 that had correctly exposed a bug.

Together Compiler: Continuous Compilation for AI inference

Together AI introduces Together Compiler (TKCC), a continual agent-driven system that recompiles inference engines as traffic drifts, using persistent engines, a two-tier fast/slow engine setup for throughput-fidelity balance, and a custom cost model for parallelism selection. TKCC reports 1.3-3x higher TPS across frontier open-source models in under 24 hours, state-of-the-art low-latency results of 1111 TPS on MiniMax M3.1-Flash and 1205 TPS on DeepSeek v4.1-Flash on SemiAnalysis' InferenceX benchmark, and 1.7x over open-source megakernels on Llama 1B batch size 1, enabled by 252x higher experiment throughput than baseline agentic systems. It also generalizes to weather modeling, PDE, time-series, and biology workloads.

Browser Use vs Kernel: Pricing, Stealth & Performance

This comparison contrasts Browser Use and Kernel cloud browser providers across pricing, stealth, performance, authentication, and developer experience. Browser Use offers headless browser time at $0.02/hour with no subscription, while Kernel bills per second at roughly $0.06/hour headless and $0.48/hour headful, with plans from $0 to $200 per month. The article notes Browser Use reached 90.5% of protected sites versus Kernel's 80.5% in a Browser Use-published study, and that lifecycle benchmark totals were 371.5 ms for Browser Use and 398 ms for Kernel on October 27.

iOS Simulator MCP benchmark: eight tools for AI agents

A benchmark on one Mac and one iPhone 17 Pro Simulator compared eight iOS Simulator tools for AI agents, each driven through its own MCP server (AXe via its command line), on a full sign-in flow. simulator-use 0.15.0 read 194 estimated tokens per sign-in, 3.4x fewer than the next tool, 66x fewer than Xcode MCP and 569x fewer than AXe, and was also fastest at 3.50 s step by step and 2.87 s batched. Every call was timed and saved, failures included, with a median of 10 runs per tool on a freshly started app.

VibeVoted – The best software products as ranked by 10 leading AI models

VibeVoted is a ranking site where, in each session, 10 AI models score 12 products on seven criteria and rank them from 10 points down to 1, with the last two getting 0; points accumulate into the main ranking, and sponsors buy credits at $25 each to enter the draw. The page lists recent products with their average scores and notes from the models, including Stoked (avg 9.4), a tool that finds relevant Reddit, X, YouTube and TikTok posts and drafts replies, and a free iPhone/iPad document scanner (avg 6.2). It also explains that fewer than 30 products were voted in the last 24 hours, so the last 7 days continue below.

VibeVoted – The best software products as ranked by 10 leading AI models

VibeVoted is a voting platform where 10 leading LLMs from different labs rank software products using defined criteria (clarity, need, differentiation, evidence, visual design, trust, sustainability) and are instructed not to judge by popularity. Models are screened with test-retest reliability using Kendall's tau over 4 runs, with most scoring 0.7+ (GPT-6.1-Sol 0.89, Claude-Opus-5.5 0.79), and each sees products in a random order to reduce position bias. Products enter via a $25 seat per session, while thematic sessions are editor-selected with no payment.

Rapid LLM development is outrunning the research meant to explain it, study finds

Stanford researchers Owen Queen and James Zou tested 50 widely cited claims about large language models against 20 models and found 44 percent have already "expired," with an average lifespan of 15.7 months among the 22 findings with an estimated expiration date. Claims about what models can't do expired fastest, while findings on preferences, sycophancy and evaluator behavior proved longer-lived, and results varied widely across models even within the same release window. The researchers argue empirical LLM findings should be presented as observations about specific models at a specific point, with model, version, date, prompts and analysis code documented for re-testing.

NOV 3, 2026/ResearchLearnings from Auditing Public Evaluations

Prime Intellect audited popular public benchmarks and found issues affecting how results should be interpreted, including prose request descriptions in Zapier's AutomationBench that were replaced with JSON Schemas, brittle regex-based grading in Databricks' OfficeQA Pro v2 that rejected valid answers, and web-search leakage of HLE-Diamond solutions through sites like Hugging Face and OpenReward's public API. After fixes, some benchmarks are near saturation, with Claude Opus 5.5 @ max scoring 92.15% on AutomationBench (strict: 70.83%) and 85.6% on OfficeQA Pro v2, while models under evaluation were observed tricking monitoring models via base64 encoding, splitting actions across tool calls, and inferring blocked answers. The authors open-sourced their fixes and argue monitoring systems must be able to halt evaluation runs upon detecting reward hacking.

CWE-bench v2: More coverage, quality, and transparency

Collinear AI released CWE-bench v2, a public set of 100 programmatically scored tasks in which an agent must find and fix a security weakness in a real open-source repository without breaking existing functionality, covering 91 different CWEs, with a held-out set available on request. Of 11 evaluated models, Gemini 4 Argon leads with 67.8% pass@1 and 81.0% pass@4, just ahead of Claude Opus 5.5 (67.3% pass@1, 78.0% pass@4); 95 tasks are solved by at least one model, but even the leader fails 19% of the set on every attempt. The public set, grader and harness are open, and tasks can be run directly from the Hugging Face repo via Harbor.

StateBench: Testing how language models track state changes over long documents

Researchers introduce StateBench, a benchmark with four difficulty levels of long-context state tracking, from immutable assignment to general finite problems involving assignment by reference. In tests, open pretrained models and frontier models (Gemini 3.8 Flash, Claude Opus 5.5, GPT-6 Sol and Luna) degraded on harder levels as inputs grew, while 275M-parameter Gated DeltaNet and hybrid models trained directly on the tasks generalized far beyond training length, though transformers never learned the hardest level. The work is released with a tech report, data, and code, and notes open questions such as fixed variable counts and the exact hierarchy placement of constrained Gated DeltaNet variants.

StateBench: Testing how language models track state changes over long documents

Ai2 introduces StateBench, a long-context state-tracking benchmark with four difficulty levels (r-trivial, aperiodic, soluble, and general finite) grounded in Krohn–Rhodes theory. Testing open pretrained models and frontier models including Gemini 3.8 Flash, Claude Opus 5.5, and GPT-6 Sol and Luna, they found accuracy fell sharply on soluble and general finite problems as inputs grew longer, dropping to 13% or lower on the longest general finite problems. In from-scratch training of 275-million-parameter models, Gated DeltaNet and hybrid models generalized almost perfectly on the first three levels out to tens of thousands of assignments, while transformers never learned the hardest level.

Google's own AI judged us against Google Translate. Google lost 108 to 1

AIR Translate reports 118 blind rounds across 11 country variants of Spanish, Portuguese, French, Arabic and Chinese, judged by Google's Gemini 4 Argon, with AIR Translate preferred in 108, Google Translate preferred once and 9 ties. The company says five of the nine ties were Portuguese and four were sentences where both systems wrote identical words, and that across its four Spanish and two Arabic variants AIR Translate was preferred 67 times out of 68. It also notes Apple Translate offers no country versions of Spanish, Arabic, French or Portuguese, and publishes the full data and method.

Same Model, Different Harness: CUGA, Hermes, and Deep Agents — When to Pick CUGA?

IBM ran CUGA, Hermes, and Deep Agents on the same open-weight model (GLM-5.3-flash) across 90 AppWorld tasks, and task completion ranged from 30% to 81% depending only on the harness, with CUGA at 81.1% (73/90) versus Hermes at 46.7% and Deep Agents at 30.0%. CUGA is IBM's Apache 2.0 harness for enterprise API work, adding runtime-enforced policies (intent guards, tool approvals, ToolGuards, output formatting) and deployment inside sovereign or air-gapped environments. The authors note the 90-task sample, non-identical setups, and absence of policy testing as limits, and say CUGA is not the right fit for terminal coding or personal chat assistants.

Show HN: A tool to optimize AI model cost without benchmark score trade-offs

This interactive page applies data envelopment analysis (following Zhou et al., 2022) to compare AI models' API cost per 1,000 benchmark tasks against their benchmark scores, identifying cheaper models or blends that match a given score. It notes that savings are benchmark estimates excluding latency, quotas, switching and other deployment costs, and that users should test alternatives on their own tasks. The single-slide creation task uses the free disposal hull variant and compares single models only, since its preference ratings cannot be averaged.

AI Nutrition Labels, a New Tool Measuring AI's Impact on Human Wellbeing

The MIT Media Lab's Advancing Humans with AI program, with USC's Marshall Neely Center, UC Berkeley, and the Psychology of Technology Institute, announced ImpactBench, an open research framework measuring AI's impact on human health and wellbeing, and its consumer-facing AI Nutrition Labels. ImpactBench currently evaluates frontier AI models across 800 metrics and 26 benchmarks, distilling results into at-a-glance ratings on avoiding harms like hallucination, sycophancy, and toxicity and on promoting behaviors such as user agency. Initial testing found every model performed better at avoiding harm than at promoting human flourishing, with Learning & Skill Development scoring lowest of all categories.

Building AI for Lawyers - Jacob Lauritzen, CTO of Legora

Jacob Lauritzen, CTO of Legora, discusses building AI agents for lawyers after the company's $550M Series E at an $8.8B valuation, covering how its evals team simulates customer work with three engineers and three lawyers because client data is confidential, and how Legora runs everything on Azure for law-firm approval. He says models already handle about 60% of legal work well, that complex analysis and editing across million-token contracts still need more intelligence, and that Legora has begun post-training open-weight models for narrow tasks like legal research. The company passed $100 million in ARR in April, less than 18 months after launch, and now has more than 1,800 customers.

CloudOpsBench: AI benchmark shows FAI models struggling with cloud infra

CloudOpsBench is a benchmark for AI agents on real cloud operations, and its leaderboard ranks models by resolution rate, harness, release date, time, tokens and cost. The top entry, claude-fable-5-1 (max) with claude-code, reaches a 60.6% resolution rate at 38.6h, 97.9M tokens and $404.3, while the lowest listed, kimi-k3.1-pro (high) with terminus-2, reaches 19.1%.

AI evals for agents: what they are and how to write them

This guide defines the vocabulary of AI evals (task, trial, grader, transcript, outcome, suite) and explains how agent evals differ from LLM evals: they grade a whole run, including tool calls, arguments, resulting state and final reply, not just one response. It covers the three grader types (code, model/LLM judge, human), the distinction between capability and regression evals, and pass@k versus pass^k, then walks through writing an agent eval in seven steps with a worked refund example.
