Model Release
Thinking Machines' Inkling Brings a 975B Multimodal Model to Hugging Face
Inkling arrived on Hugging Face on July 15 with text, image and audio inputs, 975 billion total parameters, 41 billion active parameters and a one-million-token context window. Those are publisher specifications; real-world quality and operating cost still require independent testing.
What happened and why it matters
Inkling is notable less for a single leaderboard score than for the combination of native multimodality, sparse activation and immediate support across common open inference runtimes.

What shipped
Hugging Face describes Inkling as a decoder-only multimodal mixture-of-experts model with 975 billion total parameters and 41 billion active parameters. It accepts image, text and audio inputs and supports a one-million-token context window.
The release includes full BF16 and NVFP4 variants, speculative multi-token-prediction layers, and day-one paths through Transformers, SGLang, vLLM, llama.cpp and hosted inference providers.
Why day-one tooling matters
A large open model is only useful when teams can load, quantize, serve and adapt it. Support across several runtimes lowers integration friction and gives researchers more than one route to benchmark latency, memory and quality.
The NVFP4 variant may make deployment more practical on supported hardware, but the release post is not a neutral cost comparison. Teams still need workload-specific measurements.
Evidence boundary
The architecture, context size and supported modalities come from the Hugging Face release and linked model materials. They are specifications, not independent proof of superior reasoning or agent performance.
Benchmark tables should be read with their task definitions, inference settings and comparison models intact. A large parameter count alone does not establish usefulness for a particular product.
Evidence boundary
This page reports a dated event from a named primary source. Company specifications and adoption statements remain attributed claims unless independent evidence is cited above.
