    On October 26 local time, on the same day Anthropic submitted its IPO registration filing to the SEC, OpenAI released its new model GPT-6.1 Terra, with standard API prices cut by 50% compared with the previous generation. The model focuses on visual understanding and computer operation, with standard API pricing at $1 per million input tokens, $5 for output, and $0.05 for cached input; on the Terminal-Bench 4.0 coding benchmark, it scored 50.3% at the highest reasoning effort, compared with 21.5% for the previous generation. OpenAI said Terra has approached flagship-model levels on some tasks, but the most complex coding tasks are still better suited to GPT-6.1 Sol or GPT-6 Astra.

    Baidu Open-Sources Unlimited OCR 2, a 3.34B Model Supporting Parsing of Hundreds of Pages of Documents

    Baidu has open-sourced Unlimited OCR 2, a 3.34B-parameter vision-language model that can parse hundreds of pages of books, financial reports, and reports in a single request. The weights are released under the MIT license, and the code is on GitHub. Its core change is SR-SWA sparse attention, which compresses text and visual attention into a fixed 512-token reference set, keeping the latency and memory of each decoding step essentially flat as documents grow longer. Baidu self-reports that the model scores 84.6 on MPDocBench and 77.1 on MarathonDocBench, where the next-best model Kimi-K3 scores 33.7, though its heading-hierarchy sub-item is only 48.2.

    vLLM Semantic Router Releases d3-ultra: A 27B Open Source Multimodal Decision Model

    The vLLM Semantic Router team has released d3-ultra, a 26.09B-parameter, Apache-2.0-licensed multimodal decision model that does not generate text but reads the input once and returns probabilities by question type. It supports a 131,072-token context and scored 87.2 on the team's self-built SR-Text test, higher than GLiDE V1.2's 85.1; however, on the SR-Box localization task it scored 58.2%, lower than the same-series d3-turbo's 60.0%. On a single AMD Instinct MI325X, one question with one image took 304 ms, and 255 questions took 2.16 s. All benchmark numbers are self-reported by the team on a private test set.

    Baidu Open-Sources Unlimited OCR 2 Document Parsing Model

    Baidu has open-sourced Unlimited OCR 2, which uses a new SR-SWA mechanism to compress the attention interaction between text and vision into a fixed-size working reference, thereby parsing documents of almost any length within a limited context window. Baidu says that as documents grow longer, per-step decoding latency and memory usage remain nearly constant, and that the model achieves SOTA performance on MPDocBench and MarathonDocBench, which cover documents ranging from dozens to hundreds of pages.

    Mirendil Releases Fern, Its First Model Pretrained from Scratch, Supporting 10M Token Context

    Mirendil released Fern, its first model pretrained from scratch, with a context of up to 10M tokens, equivalent to roughly 500,000 lines of code (Megatron-LM scale) or several days of an agent's work trajectory. The first version, Fern 0.1, underwent only a short round of post-training; its architecture, training, and serving were all designed for a 10M context, and next-token metrics continue to improve as context length grows. It targets high-throughput work such as auditing data, reading training logs, and reading through agent trajectories, and lists six scenarios including work on larger repositories, agentic coding, AI research code, and long-log debugging.

    Quoted postBehnam Neyshabur · @bneyshabur

    Introducing Fern, Mirendil’s first model: pretrained from scratch, with up to 10M tokens of context! That’s ~0.5M lines of code (roughly Megatron-LM scale) or days of an agent’s work, all in context at once. Its first version, Fern 0.1, had a short round of post-training 🚢 https://t.co/ClnV1Z3yzN

    OpenAI releases GPT-6.1 Terra, focused on low-cost computer operation capabilities

    OpenAI has released GPT-6.1 Terra, with API pricing at $1 per million input tokens and $5 per million output tokens, down 50% and about 58% respectively from the previous generation, and half the price of GPT-6.1 Sol. OpenAI says its task completion rate on Terminal-Bench 4.0 rose from 21.5% to 50.3%, and its error rate at the highest reasoning level on difficult factual tests dropped to 4.3%. Third-party organization Artificial Analysis measured an intelligence index of 48 points, lower than Sol's 52 points and Claude Opus 5.5's 58 points, but the average cost per task fell from $1.40 to $0.40. The model is now available via API, and Plus, Pro, Enterprise, and Edu users can use it in ChatGPT Work and Codex; ordinary Chat conversations are not yet supported.

    Amap and Alibaba Token Hub Release Humanoid Robot Model λ₀, Trained on 500 Hours of Human Video Data

    Amap and Alibaba's Token Hub business group have jointly launched the embodied intelligence model λ₀, attempting to train humanoid robots to perform full-body coordinated tasks such as walking, carrying, and two-handed manipulation using videos of everyday human activities and motion data. The team built the HumanVerse dataset, which contains 500 hours of human activity data in open environments, collecting first-person videos via wearable devices while synchronously recording body motion and reconstructing hand movements, then converting them into robot training data through viewpoint matching and motion alignment. λ₀ adopts a three-stage training pipeline and has been deployed on the Unitree G1 humanoid robot; the project's official website shows that it achieves a 90.0% success rate on the SIMPLE benchmark and completed 25 of 40 trials across four real-world mobile manipulation tasks, a 62.5% success rate, 22.5 percentage points higher than the strongest baseline compared in the paper.
