IBM has released the Granite 4.1 family of language models under Apache 2.0 license. The models come in 3B, 8B, and 30B parameter sizes. Unsloth has released 21 GGUF quantized variants of the 3B model ranging from 1.2GB to 6.34GB.
Image model releases are generating 6.5 times more mobile app downloads than traditional text model updates, according to Appfigures. Google's Gemini added 22 million downloads in 28 days following its image model release, while ChatGPT added 12 million after GPT-4o image capabilities launched.
OpenAI has released Advanced Account Security, an opt-in feature for ChatGPT users that requires passkey or physical security key authentication, automatically disables AI training on conversations, and implements shorter login sessions. The company partnered with Yubico to offer two YubiKeys for $68, nearly half the usual $126 price.
Amazon Web Services released AgentCore Optimization in preview, introducing an automated performance loop that generates configuration recommendations from production traces, validates them through batch evaluation and A/B testing, and enables continuous agent optimization. The system targets the quality drift problem where AI agents degrade as models evolve and user behavior shifts.
Amazon Web Services has released agent-guided workflows in SageMaker AI that use AI coding agents to automate model customization. The feature includes nine pre-built skills covering use case definition, data preparation, fine-tuning technique selection (SFT, DPO, RLVR), evaluation, and deployment to Amazon Bedrock or SageMaker endpoints.
Augment Code has released Cosmos into public preview, positioning it as an operating system for agentic software development. The platform coordinates AI agents across the full software development lifecycle with shared memory, multi-model routing via their Prism system that claims 20-30% token savings, and what the company calls specialized agents that learn from team feedback.
Amazon SageMaker AI now supports capacity-aware instance pools that automatically try alternative GPU instance types when primary choices lack capacity. The feature works across endpoint creation, autoscaling, and scale-in operations, eliminating the manual retry cycles that previously left endpoints stuck in failed states.
Google is rolling out a full redesign of its Gemini app that overhauls every aspect of the user interface. The update introduces a pill-shaped prompt box, colorful gradient backgrounds, and a unified bottom sheet for file uploads and tools.
Google is accelerating the rollout of Gemini features in Google Home to 16 countries across Europe and Asia-Pacific this week. The company is now clearing the early access queue daily, with users who opt-in immediately moving to the top of the list.
xAI is deploying Grok to Apple CarPlay following iOS 26.4's April 2026 update that introduced a Voice Control template for third-party AI chatbots. The move puts Grok alongside ChatGPT, Perplexity, Claude, and Gemini on 800 million iPhones, marking xAI's first deployment outside the Musk ecosystem.
NVIDIA released Nemotron-3-Nano-Omni-30B-A3B, a multimodal large language model with 31 billion parameters that processes video, audio, images, and text with up to 256K token context. The model uses a Mamba2-Transformer hybrid Mixture of Experts architecture and supports chain-of-thought reasoning mode.
OpenAI added optional AI-generated pet companions to its Codex coding assistant. The floating overlays notify developers when Codex completes tasks or needs input, eliminating the need to switch windows to check status.
Augment Code released Prism, a model routing system that selects between frontier models and cheaper alternatives per user turn. On internal benchmarks, Prism matches Claude Opus 4.7 and GPT 5.5 quality while reducing per-task costs by 20-30%, translating to approximately $20,000 monthly savings for teams sending 10,000 requests.
OpenAI added a /pet feature to its Codex Mac app that displays animated companion creatures in the interface. Users can choose from preset options or create custom pets that provide status updates while Codex runs in the background.
Perplexity CEO Aravind Srinivas revealed that the company's Mac-native Personal Computer platform has performed more than $2.8B in labor-equivalent work for Pro, Max, and Enterprise subscribers since launch. The announcement follows Apple CFO Kevan Parekh citing Perplexity as an example of developers building enterprise-grade AI assistants on Mac during Apple's Q2 2026 earnings call.
IBM released Granite 4.1 30B, a 30-billion parameter instruction-following model with a 131,072 token context window. The model scores 80.16 on MMLU 5-shot and 88.41 on HumanEval pass@1, with enhanced tool-calling capabilities following OpenAI's function definition schema.
Google published COSMO, an experimental AI assistant application for Android, on the Play Store. The 1.13 GB app runs Gemini Nano locally and includes 14 automated skills ranging from calendar event scheduling to document writing and deep research.
OpenAI is releasing GPT-5.5-Cyber to a limited group of trusted cyber defenders, according to CEO Sam Altman. The move comes weeks after Altman criticized Anthropic for restricting access to its Claude Mythos cybersecurity model to approximately 50 organizations.
xAI has released Grok 4.3, a reasoning model with a 1 million token context window and no output token limit. The model accepts text and image inputs, has always-on reasoning that cannot be disabled, and uses tiered pricing starting at $1.25 per million input tokens and $2.50 per million output tokens.
The UK's AI Security Institute has evaluated OpenAI's GPT-5.5 for security vulnerability detection capabilities. The evaluation found GPT-5.5 performs comparably to Anthropic's Claude Mythos, with the key distinction that GPT-5.5 is generally available while Mythos remains in limited release.
