not much happened today

**vLLM** announced support for **NVIDIA Nemotron Nano 2**, featuring a hybrid Transformer–Mamba design and tunable "thinking budget" enabling up to 6× faster token generation. **Mistral AI Studio** launched a production platform for agents with deep observability. **Baseten** reported high throughput (650 TPS) for **GPT-OSS 120B** on NVIDIA hardware. **Hugging Face InspectAI** added inference provider integration for cross-provider evaluation. **Thinking Machines Tinker** abstracts distributed fine-tuning for open-weight LLMs like **Qwen3** and **Llama 3**. In China, **MiniMax M2** shows competitive performance with top models and is optimized for agents and coding, while **Zhipu GLM-4.6-Air** focuses on reliability and scaling for coding tasks. Rumors suggest **Gemini 2.5 Flash** may be a >500B parameter MoE model, and a possible **GPT-5.1 mini** reference appeared. Outside LLMs, **Tahoe-x1 (3B)** foundation model achieved SOTA in cancer cell biology benchmarks. Research from Stanford introduces a method to detect model provenance via training-order "palimpsest" with strong statistical guarantees.
