Inkling 2 Small launches on Tinker at $0.30/$1.00, weights to follow
Thinking Machines' second-generation model: 594B MoE, 17B active, closed weights for now.
Thinking Machines Lab released Inkling 2 Small on November 5, 2026, the first model of its second Inkling generation. It is available now on Thinking Machines' Tinker platform for inference and fine-tuning, with closed weights at launch. The lab says it intends to release the full weights under Apache 2.0 next week, after external safety testing and red-teaming.
What changed
- Mixture-of-Experts model with 594B total parameters and 17B active per token. Text and image input, text output, with variable effort. No audio input, unlike the first-generation Inkling models.
- Tinker ID:
thinkingmachines/Inkling-2-Small. The model card lists a context window of up to 1M tokens; Tinker's serverless endpoint is listed at 256K. - Tinker serverless inference is in beta, with a waitlist for production use.
- Thinking Machines says the model will reach additional platforms in the coming weeks, after safety testing. Checkpoints become downloadable when the weights are released.
- The lab notes the model is less optimized for chat than for agentic and coding work.

What it means
Inkling 2 Small is not in the RouterPlus catalog as of November 7, 2026. The first-generation thinkingmachines/inkling-small is, through DeepInfra, at api.routerplus.com/v1. Teams that want to self-host or move to another host should wait for the Apache 2.0 weights and check the licence file when it lands.
