OpenAI

⭐⭐⭐ [Product Update] Build more responsive apps with the Decisions API

OpenAI announced general availability of the Decisions API. Built with GPT-6 Luna, the API focuses the model on questions with bounded answers, letting applications and agents make near real-time decisions from text, images, and structured inputs up to 10x faster than GPT-6 Luna through the Responses API, according to OpenAI. Since the public beta it added a native GPT-Live integration, prompt caching for reused context, inference residency in the US and EU, native JSON inputs, images in question instructions, up to 400 questions per request (twice the previous limit), and additional capacity in several Asian regions to further reduce latency. Developers define a question and its allowed answers, supply context, and receive one of three answer types: a probability, a choice, or a score. Cited customer results include Box reporting ~5x faster route selection on 30 certificate of insurance cases at the same accuracy as the Responses API, Datadog reporting 40x faster p95 with comparable accuracy, Ramp reporting 4x faster and 30% cheaper than GPT-6 Luna, Sierra reporting under 280 ms p95 with about 3x speed and 90% lower cost per call, and Speak reporting its GPT-Live integration cut time to next action from 1.4s to 0.13s.

⭐⭐ [Other] OpenAI and Poland’s NASK partner to advance AI safety and security

OpenAI and Poland's NASK National Research Institute have signed an agreement to explore collaboration on AI safety, security and technical research, combining expertise to better understand emerging risks and strengthen safeguards. NASK's AI Safety Research Center, which serves as the Polish AI Safety Institute (AISI), will work with OpenAI on safety research, including ways to evaluate increasingly capable AI systems, identify potential vulnerabilities and strengthen safeguards. NASK director Radosław Nielek said the institute's work spans safeguards against emerging risks, detection of synthetic AI-generated content and the multilingual aspects of these challenges, adding that AI safety cannot be achieved in isolation. OpenAI's Tom Duff Gordon said the agreement brings Poland's research expertise into the international effort to make AI safer. The post also notes that in July CERT Polska, which operates within NASK, gained access to OpenAI's cyber-capable models through Daybreak and used them to help discover six vulnerabilities in MikroTik RouterOS, for which the vendor released fixes.

MiniMax

⭐⭐⭐ [Model Release] MiniMaxAI/MiniMax-M3.1-Flash

MiniMax released MiniMax-M3.1-Flash on Hugging Face, a native multimodal mixture-of-experts model targeting coding, agentic workflows, computer use and cybersecurity, accepting text, image and video inputs with text output and a context window of up to 1M tokens. The model card lists roughly 428B total parameters with 23B activated per token, MiniMax Sparse Attention throughout the model, an included DSpark draft head for speculative decoding, and the minimax-community license. Relative to M3, M3.1-Flash keeps the MoE architecture with three changes: the first three full-attention layers are replaced by sparse attention, quantization-aware training is applied to the routed experts and attention paths, and DSpark replaces the earlier EAGLE-like MTP approach. Reported scores include 76.2 on BankerToolBench, 73.7% on DeepSWE v1.1, 61.7 on OSWorld 2.0, 29.6 on Agents' Last Exam and 82.2 on CyberGym, shown in a benchmark table alongside DeepSeek V4.1 Flash, Kimi K3, GLM-5.3, GPT-5.6 and Opus 5. The page lists three usage paths: MiniMax Agent, the MiniMax API and local deployment.

Tencent Hunyuan

⭐⭐⭐ [Model Release] tencent/Hy-Nomas

Tencent Hunyuan released Hy-Nomas, a video world generation model that supports free-form, multi-turn interaction via text instructions and camera control, generating a world one segment at a time so users can introduce objects, change styles and scenes, describe actions, or move the camera as generation proceeds. It combines a segment-autoregressive diffusion transformer, a Qwen text encoder (the language-model component of Qwen2.5-VL-7B-Instruct), camera-conditioning modules, and a PixelUMM video decoder, with a persistent KV cache carrying context between segments. The distilled inference configuration uses 8 denoising steps at 720 × 1280 and 24 FPS, and a separate configuration runs on a single NVIDIA RTX 4090 with INT8 DiT weights, an INT8 KV cache, an FP8 decoder, and CPU offload. The team also released Hy-Nomas-Bench, four benchmarks with 280 test cases covering multi-turn free-form text interaction, camera navigation, interleaved text and camera control, and spatial memory, with structured prompts, interaction sequences, keyboard timelines, and reference camera trajectories. The model is released under apache-2.0.

⭐⭐⭐ [Model Release] tencent/WeVisOne-VL-2B

Tencent's WeChat Vision team released WeVisOne-VL-2B on HuggingFace, an Apache-2.0 open-weight unified vision-language model built on Qwen3-VL. It unifies object-level perception (open-vocabulary detection, referring localization, counting, pointing, OCR) with pixel-level perception (referring segmentation and promptable alpha matting) via structured next-token prediction plus a lightweight 9.5M-parameter pixel decoder. The model uses dedicated coordinate tokens (<0> through <1000>) for normalized boxes and points, returns None when a queried target is absent, and emits a special instance token (<OBJ>, token ID 152678) after each predicted box for dense tasks; the required mask_decoder.pt contains a visual feature adapter, a 6-block deformable cross-attention box-guided query decoder, and a dense prediction head that refines predictions across S/4, S/2 and S/1 to output full-resolution alpha mattes at stride 1. The release is stated as intended for research in visual grounding, referring segmentation and image matting, not for autonomous high-impact decisions or identifying individuals, and limitations include sensitivity of fine alpha boundaries to resolution, occlusion, complex transparency and prompt phrasing, no explicit chain-of-thought reasoning, and single-turn image-only perception (video grids are rejected by the pixel decoder).

⭐⭐ [Model Release] tencent/WeVisOne-VL-4B

Tencent's WeChat Vision team released WeVisOne-VL-4B, a unified vision-language model built on Qwen3-VL that combines object-level perception (open-vocabulary detection, referring localization, object counting, pointing, OCR) with pixel-level perception (referring segmentation, promptable alpha matting) via structured next-token prediction and a lightweight 9.6M-parameter pixel decoder. The model uses dedicated coordinate tokens (<0> to <1000>) for normalized boxes and points, returns None for absent targets, and emits a special instance token (<OBJ>, token ID 152678) after each predicted box for dense tasks. The required mask_decoder.pt (9,609,764 parameters) combines a visual feature adapter over multi-level Qwen3-VL ViT features, a box-guided query decoder with 6 deformable cross-attention blocks, and an instance-conditioned dense prediction head producing full-resolution continuous alpha mattes. The release is positioned for research on visual grounding, referring segmentation and image matting, and is not intended for autonomous high-impact decisions or identifying individuals; limitations include sensitivity of fine alpha boundaries to resolution, occlusion, complex transparency and prompt phrasing, no explicit chain-of-thought reasoning, and single-turn image input only. Code is released under Apache 2.0.

Model Release

⭐⭐ [Model Release] OlmoEarth v1.3: State-of-the-art embeddings for the whole planet

Ai2 released OlmoEarth v1.3, a satellite embedding model that reads a year of Sentinel-1 radar and Sentinel-2/Landsat multispectral time series and produces one 128-dimensional vector per 10-meter pixel worldwide, with the first 64 dimensions usable on their own as a smaller embedding. The team also published precomputed annual global embeddings (10m, 64- and 128-dim) on Source Cooperative and launched the browser-based OlmoEarth Embeddings Explorer, which requires no sign-in. Across 27 evaluations spanning six continents against AlphaEarth Foundations and Tessera v2, the 128-dim embeddings scored highest on 20 of 27 and ranked highest overall, while the 64-dim version led on 18 of 27; the evaluation introduces PLANTEUR, a new crop-type benchmark for tropical farming. Ai2 says v1.3 was its cheapest OlmoEarth to train, using 53% of v1.2's and 18% of v1's compute time, with 50% and 22% of the carbon emissions, while matching v1.2 on fine-tuning performance across research and partner labels. Model weights, pretraining data and code are fully open, and reproducing the base pretraining run would cost roughly $2,720 in rented H100 time.

⭐⭐ [Product Update] NVIDIA Unveils Minerva to Bring End-to-End Observability for AI Factories

NVIDIA launched Minerva, an AIOps platform built to help teams find problems earlier and keep AI factories productive. It brings together telemetry from infrastructure and AI workloads, then applies purpose-built AI models to turn that data into timely, actionable insight. The post notes that AI factories are among the most complex operations in the world.

⭐⭐ [Product Update] Does Your Model Run on AWS Trainium? Look It Up

A Hugging Face blog post presents a lookup tool for torch-neuronx model support: a Space that reports whether popular Hub Transformers models run unmodified on AWS Trainium. Each entry shows the result, the number of Trainium cores the model is sharded over, wall time including compilation, peak device memory, plus the Neuron stack versions, packages to install and the run.py script that was used; the script follows the TorchNeuron recipe, loading with from_pretrained, sharding when needed, and generating with a static cache and torch.compile(backend="neuron"). Tests load the model on a trn2 instance sharded over the smallest number of cores that fit its weights, generate 32 tokens and check them — compared against a CPU run of the same checkpoint on a single core, or judged for fluent English by a small judge model when sharded; only models fitting on 4 Trainium2 devices (16 cores) are tested, and a PASS says nothing about throughput or longer generations. All results come from the public aws-neuron/torch-neuronx-model-support dataset, with one Parquet file per neuronx-cc and library version pair, and a public NEFF cache lets users skip the first-run compilation.

⭐⭐ [Product Update] Introducing our Training API

Modal released Spindle, an open-source, Tinker-compatible training server that runs inside the user's own Modal workspace. Training loops are still written in plain Python on a laptop while forward and backward passes run on GPUs, and because the user owns the server they can customize it and pay for GPU time rather than tokens. Deployment takes a single command, 「spindle deploy」, after which a training script runs against the server. Spindle supports full-parameter training and multi-LoRA across a range of open models, and handles hundreds of concurrent training runs. Underneath, it uses Modal primitives: Clusters schedule requests on dynamically available RDMA-connected nodes, Volumes provide durable checkpointing, and Servers provide the inference layer; the backend consists of disaggregated trainer engines and inference pools that need not share accelerators or precision. The post also references Modal Dojo, a training library released the day before, upstream improvements contributed to Miles and SGLang, and an example rerunning Jasper Lu's GRPO multi-turn search agent training by changing only BASE_URL and API_KEY to point at a Spindle deployment.

⭐⭐ [Product Update] Replit Monitoring Agent: Your very own software engineering team

Replit launched the Monitoring Agent, which it describes as an autonomous on-call engineer for every app builder. When a production issue occurs, the agent can investigate the alert, identify the cause, make and validate a fix, deploy it to production, and then report back on what happened and what changed. This builds on App Monitoring, launched earlier this year, which provided production health checks and alerts when a published app went down. Replit says the new agent closes that loop so it not only reports what broke but also performs the fix, aimed at internal app builders and small entrepreneurs who would otherwise handle on-call duties themselves.

⭐⭐ [Research] Turning Database Grading into RL Rewards: Post-Training Agents with ThinkingBox

ThinkingBox-Training is now available on GitHub. ThinkingBox evaluates an agent by comparing the final database state with the expected outcome, and the authors use this executable check as a training reward. The team built a training pool from ThinkingBox-format tasks outside ThinkingBox-Bench and estimated each task's success probability once with the base policy before training, using this offline policy-relative difficulty to select tasks while keeping the pool fixed throughout the run. After 50 GRPO steps on Qwen3.8-27B, pass@1 rose from 51.70% to 60.78%, tasks passing all 20 attempts rose from 38 to 107, and pass@20 fell from 453 to 446.
