Thinking Machines Inkling 7/15 one-day triple: ~1T multimodal open-source + vLLM day-0 + SGLang day-0, 380 tok/s/user MTP8 on Blackwell

On 2026-07-15 Thinking Machines published Inkling on Hugging Face — a ~1T parameter open multimodal model (image / text / audio native inputs, 45T training tokens, 975B total / 41B active MoE, 1M context, relative attention, 5:1 sliding-to-global hybrid attention, hierarchical MLP patchifier + mel-spectrogram discretization); same day vLLM blog posted day-0 support (NVFP4 + BF16 dual-variant full feature parity, 8 MTP heads, 380 tok/s/user MTP8 on 4x GB200 with mean acceptance length 4.5, 140 tok/s/user without MTP, 1M context accuracy-by-length-bucket 99.09% / 95.68% / 81.36%); same day LMSYS posted SGLang day-0 support (71.7k tok/s input throughput on Blackwell, SGLang Cookbook publishes TP4 / TP8 / H200 / AMD MI350X / MI355X deployment recipes). The three releases together form 'one of the strongest single days in the July open-source AI ecosystem: a 1T multimodal open model + same-day inference engine readiness.'
