OpenAI just open-sourced Codex Security, releasing a CLI and TypeScript SDK built to find, validate, and patch security vulnerabilities in codebases. It supports scanning entire repositories, specific paths, or git diffs, and can automatically generate fix patches with models like gpt-5.6-sol. The tool itself is free, though running scans requires bringing your own OpenAI API key or account login.
Google just rolled out major updates to Gemini API Managed Agents, making Gemini 3.6 Flash the new default model. Developers can now run custom pre- and post-tool scripts inside remote sandboxes to lint or block actions, set hard token limits to stop runaway costs, and test autonomous workflows on a free tier.
xAI just brought Grok 4.5, its smartest coding model, to millions of GitHub Copilot developers across VS Code, Copilot CLI, and cloud agents. You can simply pick it from the model selector (though some enterprise accounts require an admin toggle first), or access it directly via xAI's console starting at $2 per million input tokens.
xAI just rolled out Build Mode in early beta for Grok, letting users turn chat prompts into interactive websites, apps, and even 3D games. The model writes the code and runs a live preview right inside the chat window with zero setup required, and projects can be published instantly to a grok.me link or custom domain. It is currently limited to SuperGrok Heavy subscribers.
Alibaba just open-sourced qwen-audio-agent, a full-duplex voice runtime bridging conversational audio with background task agents. Users can converse and interrupt naturally while backend agents like OpenCode or Claude Code handle long-running code edits and report back when finished.
Anthropic just expanded its enterprise partnership with IT giant Cognizant, designating it a Global Premier Partner. Cognizant has trained over 30,000 associates on Claude and is baking Claude Code into its internal developer platforms to deploy custom agentic systems for healthcare and insurance clients. Why it matters: Frontier AI is moving from cool demos to messy enterprise plumbing, and Anthropic is leaning on global consultancies to do the heavy lifting.
Anthropic just launched Claude Opus 5, bringing near-Fable 5 frontier intelligence to everyday workflows at half the price. It sets state-of-the-art results across coding benchmarks and scores three times higher on ARC-AGI 3 than the runner-up. Why it matters: developers get near-flagship autonomy and reasoning at the price point of prior midrange tiers.
Microsoft just deployed two specialized MAI models inside GitHub Copilot and Excel. MAI-Code-1-Flash delivers a 10% higher code accept rate than GPT-5.4 Mini with 10% fewer tokens, while the Excel variant matches GPT-5.6 quality on common workflows while running on older A100 GPUs. Microsoft is basically proving that vertical in-product training can beat giant general-purpose models on cost and speed.
xAI just introduced Workflows in Grok Build, turning natural language prompts into orchestration scripts that fan work out across parallel agents. It deploys 128 agents by default and up to 1,024 for heavy jobs to review code, verify findings, and synthesize reports in the background. Completed workflows can be saved as slash commands for team reuse.
Cursor just launched Cursor Router for Teams and Enterprise plans, an intelligent model switcher trained on over 600,000 real-world coding requests. Instead of burning expensive frontier tokens on everyday boilerplate, it evaluates prompt complexity, domain, and cache hit trade-offs to route tasks to the best model. In live A/B tests, teams cut token costs by up to 60% across three customizable optimization modes.
Anthropic just added an interactive iOS simulator directly into Claude Code Desktop on macOS in public beta. Instead of juggling windows, the simulator pops up right next to your conversation so Claude can build the app, tap through screens, and verify its own fixes live. It's available on Pro, Max, and Team plans with Xcode installed.
Poolside just released Laguna S 2.1, a 118B MoE coding model that activates only 8B parameters per token alongside a 1M token context window. Built in under nine weeks, its thinking mode boosts DeepSWE benchmark scores from 16.5% to 40.4%, matching or beating models many times its size. Weights and full evaluation trajectories are already available for download.
Browser-use just merged a new feature into browser-harness that records browser agent sessions and automatically edits them into Screen Studio-style clips. The agent captures per-action screenshots, hides sensitive credentials, and renders smooth zooms, synthetic cursors, and captions inside the browser without needing ffmpeg.
Roblox just unveiled Build, a mobile-first AI creation tab inside its app that lets anyone generate playable 3D games directly from plain text prompts without writing code. The tool automates mechanics, environments, characters, and audio using proprietary 3D gaming models. It launches a free public alpha in New Zealand on July 28, with professional testing and analytics agents coming to Studio soon.
Bolt just open-sourced Bolt Slides, a presentation builder that turns static decks into living web applications. Instead of exporting dead PDFs, users can embed live data, 3D models, and clickable prototypes directly into slide links. It is available to all Bolt.new users and can also be run locally with agents like Cursor or Claude Code.
Google just fell months behind schedule releasing its flagship Gemini 3.5 Pro model after it failed internal coding benchmarks. A late-June attempt to refresh training data yielded disappointing results, and competing internal teams across Cloud, DeepMind, and Android are compounding delays. Alphabet shares slid 3.2% as engineers voice frustration over falling behind OpenAI and Anthropic.
Moonshot AI just unveiled Kimi K3, a 2.8-trillion parameter model claimed as the world's first open 3T-class frontier model. Built on a sparse MoE activating 16 of 896 experts, K3 features native vision, a 1-million-token context window, and high-level autonomous coding skills. Full model weights are set to drop on July 27, 2026.
xAI just released Grok 4.5, its flagship model tailored for coding, agentic workflows, and knowledge work. Trained alongside Cursor on tens of thousands of NVIDIA GB300 GPUs, it delivers 80 TPS generation speed and double the token efficiency of rivals, priced at $2 input and $6 output per million tokens. It is currently available with temporary free access in Grok Build and Cursor.
OpenAI just dropped Codex Micro, a $230 physical macropad built with Work Louder to manage its Codex coding platform. The hardware packs 13 mechanical keys, a dial, and a joystick to monitor agent thread statuses via colored lights, tweak reasoning levels on the fly, and approve code changes. All controls are remappable through the ChatGPT desktop app.
xAI just open-sourced Grok Build, releasing the harness behind its coding agent and terminal UI on GitHub. The release details how it handles context assembly and tool dispatch, while offering plug-in support for MCP servers and subagents. Best of all, developers can compile it themselves and run it fully local-first with their own inference.
