Summary

The AI landscape experienced a dynamic week with numerous model releases and updates. OpenAI launched GPT 5.5, with internal testing for GPT 5.6 and a dedicated GPT 5.5 Codex model anticipated soon. Google is preparing to unveil Gemini 3.5 at its upcoming developer conference, enhancing the Gemini app with file generation and a sandbox environment. New open-source models, Xiaomi's Mimo v2.5 Pro (1 trillion parameters, 1M context) and Poolside AI's Laguna XS2 (33B MoE), are outperforming established models in coding and reasoning. Claude Code received significant updates, including new connectors for Blender and Autodesk Fusion, quality-of-life improvements, and pricing plan adjustments. Nvidia released Neatron 3 Nano Omni, a 30 billion parameter multimodal model, open-sourced for local deployment. Deepseek extended its v4 Pro API discount, and Mistral AI is rumored to be launching a 128 billion parameter "Mistral medium" model. China is also advancing AI robotics in retail, replacing human cashiers with automated systems.

Key takeaway

For AI Engineers evaluating new models for agentic or coding workflows, consider the emerging open-source options like Xiaomi's Mimo v2.5 Pro or Poolside AI's Laguna XS2, which offer competitive performance and flexibility. Your choice should balance raw capability with cost-efficiency and the ability to integrate into existing ecosystems, especially as major labs vertically integrate their tooling. Monitor Google I/O for Gemini 3.5 and anticipate further specialized model releases from OpenAI and Mistral AI.
