  OpenAI models come to Google Cloud's Model Garden
  GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna are in private preview on Google Cloud, with Codex agentic workflows, and general availability is planned in the coming weeks. You pay through Google Cloud Marketplace, and the spend can draw down existing GCP commitments. OpenAI models are also coming to Google Antigravity and the Gemini Agent. If your agents already run on Google Cloud, you'll soon be able to switch models without signing a separate vendor contract. Source

  NVIDIA adds open Nemotron 3.5 retrieval models for embedding, reranking, and document parsing
  The new Nemotron Retriever models are open and commercially available. NVIDIA's pitch is that better retrieval gets agents to grounded answers with fewer repeated searches and fewer wasted tokens. Worth testing if your agents lean on RAG. Source

  Mistral releases Voxtral 3 speech models and a voice agent SDK
  Built on LiveKit, the SDK runs transcription, reasoning with tool calls, and speech in one streaming pipeline, and Mistral says each turn completes in under a second. Transcription covers 50+ languages, and the voice agent API starts at $0.04/min with Mistral Small 4. If you're building phone or support agents, note that it runs on Mistral's EU, US, and global endpoints or self-hosted. Source

  Meta releases Muse Glimmer 30B, an open on-device agent model under Apache 2.0
  It handles tool use, multi-step planning, and failure recovery locally, takes text and image input, and is quantized to about 4-bit so it runs on a single GPU. Meta says it beats Gemma4-31B and Qwen3.6-27B on agentic benchmarks. Worth a look if you want your agent runs to stay on your own hardware. Source

  Replit makes OpenAI the default model for Replit Agent
  CEO Amjad Masad pointed to cost, the partnership, and performance, and Claude models are still selectable. If your build depends on how Claude behaves, pin the model rather than trusting the default. Source

  Reflection releases Beam, an open-weight 501B MoE model (23B active) under Apache 2.0
  It's built for coding and long-horizon agent work, with weights on Hugging Face and 40+ launch partners. If you self-host your agent backend, this is a permissively licensed option worth a look. Source
