Overview
The lighter Inkling: a 276B-total / 12B-active MoE that matches its larger sibling on many benchmarks at a quarter of the size, with the same native text/image/audio reasoning and variable thinking effort. Open weights on Hugging Face, sold through Tinker serverless inference at $0.30/$1.20 per 1M tokens.
Deploy this open model on rented GPUs
Open weights mean you can self-host instead of paying per-token API prices. These platforms let you serve it on demand — often cheaper at scale.

Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA Intelligence Index: 40.2 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- AA Agentic Index: 30.8 (Tool use, planning, autonomy)
- AA-Omniscience Index: -9 (−100–100)
- LMSYS Chatbot Arena: 1430.5 ELO (Human preference)
- Ranks #53 of 136 comparably-measured models by percentile score, across 4 independent measurements
- Ranks #21 of 136 comparably-tested models by normalized performance per dollar
