Google released Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking, two new speech-to-speech models for Gemini Live. The release includes a WebSocket connection to wss://generativelanguage.googleapis.com/ws/google.ai.generativelanguage.v1alpha.GenerativeService.BidiGenerateContent with the model running via a browser voice conversation UI. Users can pick a model and voice preset, optionally set a system prompt, and interrupt the model during playback.
Meta announced that its WhatsApp Business Tools MCP server lets AI coding agents like Claude and Codex perform WhatsApp Business onboarding, phone verification, template management, and webhook setup. The company said WhatsApp paid messaging crossed a $2 billion annual run rate in Q4 2025, and the new MCP server is rolling out gradually in beta. Developers can hand setup and ongoing configuration tasks to agents instead of manually switching between Meta settings, API documentation, and code tools.
Google released Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking as production-focused speech-to-speech dialogue models for real-time voice agents. The Extended Thinking model scored 82.6 on Artificial Analysis’ Speech to Speech Quality Index. Google’s offering shifts voice agents toward tool-using, multi-step reasoning while keeping streamed conversation and speech, and it’s available via the Gemini Live API with $0.005/min input and $0.018/min output audio.
Meta will let developers use AI agents to set up and manage WhatsApp Business messaging via a chat-based workflow. The change is enabled by the new WhatsApp Business Tools MCP server that connects an AI coding agent to the WhatsApp Business Platform. Setup steps like creating and verifying the WhatsApp Business account and configuring Cloud API access can now be handled by the agent instead of manually switching among multiple developer tools.
Google introduced Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking as new near real-time voice dialogue models for developers and enterprises. Gemini 3.8 Live Extended Thinking ranked #1 with a score of 82.6 on Artificial Analysis's Speech to Speech Quality Index. The rollout expands voice-agent capabilities across the Gemini API, Google Workspace, Search Live, and the Gemini Live app, with added support for multi-language switching, background tool calls, and simultaneous speech during multi-step reasoning.
ZeroClick helps businesses sell to AI agents by turning an API or product into a storefront that AI agents can discover and purchase from. The listing says the launch is free to start. It adds payments, pricing controls, and transaction tracking in one place, changing how products are packaged and sold to AI agents.
Amazon Bedrock prompt caching can store partially processed input context and reuse it on later requests, reducing how often the model reprocesses the same tokens. It cuts billed input token costs for cache reads by up to 90% when the request hits an existing cache entry. This changes deployments by shifting static prompt sections (like long documents or system/tool definitions) into cached prefixes to lower time-to-first-token and input token charges without changing the model or prompt quality.
Superpose, an iOS camera app from former TikTok employees Melody Chu and Jing Liu, generates pose suggestions from selfies or a friend’s photo using AI. It launched in July and has been downloaded over 22,000 times, with users generating more than 190,000 poses. The app offers five free generations daily and adds paid packs priced at $2.99 for five more or $9.99 for 20, while the founders say they will improve pose style and personalization.
GBrain launched a unified API that provides shared “memory” and connected accounts so multiple AI tools (like Claude Code and ChatGPT, and tools such as Cursor) can access the same saved data. It offers $100 off the first month for a team workspace. Teams can run it on their own inference or on the vendor’s service in a shared workspace, reducing per-tool setup such as key configuration.
Statable Analytics launched a web analytics service aimed at being usable by humans and AI agents via an MCP connection. The page shows it has 240 followers. It offers a simple dashboard plus agent integrations for reading reports and configuring tracking, with no cookies and EU-hosted data in most cases.
Directus launched Monospace as its 5th release, positioning it as a governed API layer that connects enterprise data to app builders, business teams, and AI agents.
Ramp launched in the UK and added ElevenLabs as a client, positioning its AI token spend platform to attract more UK startups. Ramp said AI spending across its customers has grown about 21 times since June 2025. The company is expanding its spend management offerings for UK businesses, including breaking down token costs by model and team and partnering with Visa to support corporate cards.
