Inkling 2 Small is Thinking Machines' second-generation 594B-total, 17B-active mixture-of-experts model with image input. its weights are closed for now; the lab plans an Apache 2.0 release. on octomind it is served only through Tinker.
pick it if
want the lowest-priced Inkling on octomind, below Inkling Small on both input and output
need adjustable reasoning effort, with chain-of-thought you can switch off
work on long agent runs: the lab trained it with a 256K window plus compaction
skip it if
you need open weights today; the lab has not released them yet
you need audio input; Inkling 2 Small takes text and images only
Inkling Small is Thinking Machines' 276B-total, 12B-active mixture-of-experts open-weights model, the smaller sibling of Inkling. the lab reports performance comparable to Inkling at a quarter of its size; on octomind it costs half Inkling's input rate and under a third of its output rate.
pick it if
want the Inkling family's lower-priced tier with image input
need adjustable thinking effort, from minimal to xhigh
want Apache 2.0 open weights you can fine-tune or self-host
skip it if
you lean on knowledge recall; the lab says Inkling keeps the factuality edge
faq
which is cheaper, Inkling 2 Small or Inkling Small?
Inkling 2 Small lists lower input and output prices. on a coding-agent session (2M tokens in, 60,000 out) Inkling 2 Small costs $0.66 and Inkling Small $1.07.
can i switch between Inkling 2 Small and Inkling Small mid-task?
yes. in an octomind session, /model octohub:inkling-2-small and /model octohub:inkling-small switch models without losing the conversation, so you can draft on one and review on the other.
try either model
switch between models inside the same octomind session.
