Inkling

Thinking Machines' 975B Apache-2.0 model that takes text, images and audio natively

Inkling is the first open-weights model from Thinking Machines Lab, released 15 July 2026 under Apache 2.0. It is a 975B-parameter mixture of experts with 41B active per token, trained from scratch on 45 trillion tokens of text, images, audio and video, with a context window up to 1M tokens. The architecture uses 256 routed experts plus 2 shared experts per layer with 6 routed experts active per token, a sigmoid router, and interleaved sliding-window and global attention at a 5:1 ratio. It accepts text, image and audio input natively and returns text. Weights are on Hugging Face in both the original format and an NVFP4 checkpoint for Blackwell hardware. A distilled Inkling-Small followed on 31 July.

Modalities LLMs, Multimodal Reasoning
Best For Best Open-Weight Multimodal Base
Date Added 2026-08-04
1 Feed audio as 16kHz WAV under about 20 minutes, which is the range it was tuned for
2 Keep images between roughly 40px and 4096px on the long edge
3 Use the controllable thinking effort setting rather than paying for maximum reasoning on every call
4 Treat the vendor benchmark numbers as an upper bound, they were run at effort 0.99 and temperature 1.0
5 Try a hosted inference provider before committing to 975B of self-hosted infrastructure

Domain Fine-Tune On An Open Base

Adapt a frontier-scale multimodal model to a specific domain without licence negotiation.

STEPS:
  1. Confirm Apache 2.0 covers the intended commercial use
  2. Assemble a domain dataset spanning the modalities you actually need
  3. Fine-tune on Tinker or your own infrastructure
  4. Evaluate against the base checkpoint on your own tasks
  5. Deploy through vLLM or SGLang
  6. Keep the base model available as a control for regressions

Audio And Document Understanding In One Model

Process recordings and scanned pages without a separate speech pipeline.

STEPS:
  1. Convert recordings to 16kHz WAV segments under 20 minutes
  2. Send audio and page images in the same request
  3. Ask for a structured summary rather than free text
  4. Spot-check transcription-dependent claims against the source
  5. Batch through a hosted provider if volume is bursty
  6. Compare cost against a separate ASR plus LLM pipeline
