Thinking Machines releases Inkling, a Mixture-of-Experts model with 975B total parameters and 41B active parameters that supports a 1M token context window. The model was pretrained on 45 trillion tokens and is available for fine-tuning on Tinker alongside a preview of Inkling-Small with 12B active parameters. Inkling features an encoder-free architecture for audio and vision inputs and supports controllable thinking effort, spending one third as many tokens as Nemotron 3 Ultra to achieve the same performance on Terminal Bench.written, reviewed, cited
- The model was evaluated on Design Arena's Agentic Web Dev leaderboard where blinded human evaluators compare generated web apps head to head.

Inkling provides efficient open models for text, images, and audio available to fine-tune on Hugging Face or via the Tinker training platform. The most capable variant contains 975B total parameters with 41B active, while the smaller size has 276B total and 12B active parameters. Both models support a context of 1M tokens and match larger siblings on benchmarks at a quarter of the size.written, reviewed, cited

Thinking Machines releases Inkling-Small, an efficient open-weights Mixture-of-Experts model with 276B total parameters and 12B active trained on NVIDIA GB300 NVL72 systems. The model features a context window of up to 1M tokens and achieves comparable performance to Inkling at a quarter of its size across agentic tool use (Terminal-Bench 2.1), reasoning (HLE text-only), and instruction following (IFBench) benchmarks. It is available for fine-tuning on Tinker and for text, image, and audio chat on Tinker Playground, with variable thinking effort to balance cost and performance.written, reviewed, cited
- Inkling-Small surpasses Inkling on reasoning and agentic coding benchmarks despite Inkling maintaining an advantage on knowledge coverage and factuality.
- The model uses an encoder-free architecture where images are divided into 40×40-pixel patches and transformed using a four-layer hMLP.
- ForecastBench and Prophet Arena results were obtained during testing between July 19 and July 28, 2026.

Thinking Machines Lab released Inkling, a 66-layer decoder-only transformer where each token is routed to 6 of 256 experts, on July 15, 2026. The model features 975B total parameters with 41B active and supports BF16, MXFP8, and NVFP4 numerics. Running the BF16 checkpoint requires a GPU cluster with at least 2 TB of aggregated VRAM, while the NVFP4 quantized alternative reduces this requirement to at least 600 GB. It accepts text, image, and audio inputs and supports a context window of up to 1M tokens under an Apache 2.0 license.written, reviewed, cited
- Running W4A4 mode on NVIDIA B300 GPUs additionally requires SM100+ architecture.
- The model is designed to be used by developers building agentic and tool-use systems.
