How to use Inkling for free
Free Unlimited
Inkling is Thinking Machines' open-weight model, built with a sparse activation design that only engages a fraction of its full size for any given request. On Tusk Central AI, it's available in the Free Unlimited tier — no daily caps, no credits, no subscription.
What Inkling is good at
Inkling's architecture — activating only part of its full capacity per request — lets it respond quickly while still drawing on a large underlying model when a task calls for it. That makes it a solid everyday option: fast enough for quick questions, with enough depth in reserve for tasks that need more than a surface-level answer.

How it compares
Inkling sits alongside other free models like GLM 5.2 and MiniMax M3 on Tusk Central AI. Its sparse-activation design is what sets it apart architecturally — worth trying if you want a model that balances speed and depth without moving to a credits-based deep-thinking tier.
