04 — Questions

Which should you choose?

Which is better: Inkling Small or Muse Spark 1.1?

It is close. Our weighted score puts them within a point (Muse Spark 1.1 69/100, Inkling Small 68/100), so choose by what matters most for your work: Muse Spark 1.1 for raw capability and Inkling Small on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, Inkling Small or Muse Spark 1.1?

Inkling Small is cheaper at $0.58 input / $1.44 output per million tokens (official Thinking Machines API price). Muse Spark 1.1 costs $1.25 input / $4.25 output per million tokens (official Meta API price). At a typical mix of three input tokens to one output token, that is $0.795 per million tokens for Inkling Small versus $2.00 for Muse Spark 1.1 (2.5× as much).

Which scores higher on benchmarks?

Muse Spark 1.1 scores higher on the Capabilities Index (ECI): Muse Spark 1.1 154.2 (#46 of 165) and Inkling Small 150.5 (#58 of 165). The confidence ranges of the top two overlap (151.3–156.4 vs 147.7–152.4), so treat the gap as small. On individual benchmarks: SimpleQA Verified — Muse Spark 1.1 57.8%, Inkling Small 19.1%.

Which is better for coding?

There are no published SWE-bench Verified results for Inkling Small and Muse Spark 1.1 yet, so there is no like-for-like coding score. On overall capability, Muse Spark 1.1 leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.

Which has the bigger context window?

Inkling Small and Muse Spark 1.1 share the same 1,048,576-token context window. Maximum output per response: Inkling Small up to 1,048,576, Muse Spark 1.1 up to 131,072 tokens.

Inkling Small accepts text, images and audio; Muse Spark 1.1 accepts text, images, PDFs and video. Muse Spark 1.1 handles the widest range of inputs.

Are any of these open source?

Inkling Small publishes its weights (Apache-2.0) and can be self-hosted; Muse Spark 1.1 is proprietary.

Which is newer?

Inkling Small is the newest, released Jul 30, 2026. Muse Spark 1.1 came out Jul 9, 2026.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Nov 2, 2026.
