All 24 rowsWhat it costs to get this score
Published API price against the public score. The x-axis uses a log scale; the dashed path marks models that are not beaten by a cheaper, higher-scoring option. Price uses average of published input and output rates.

Lineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
Inkling ranks #89 of 221 on the public leaderboard with a score of 52.13/100. Its source-verified position is #51 of 85.
Inkling is a open weight model with a 1M context window. No explicit reasoning mode is documented in this profile.
Inkling sits in the Inkling family with Inkling-Small. 24 of 670 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Its strongest eligible category is Mathematics at #11, while its lowest eligible position is Coding at #80. particularly strong for mathematical reasoning, scientific computing, and quantitative analysis.
Last updated October 14, 2026. Runtime fields remain blank until a sourced snapshot exists.
Deployment options
Self-host and provider-specific paths stay separate from benchmark evidence so operating constraints are visible before a score becomes the whole decision.
Published weights are available, but BenchLM does not yet have a sourced parameter and VRAM profile for this exact model. Hardware cost estimates stay unavailable until that sizing record is complete.

How does Inkling perform overall in AI benchmarks?
Inkling ranks #89 out of 221 models on the public BenchAlign leaderboard, with a score of 52.13/100. Its evidence status is Supported, and this profile shows 24 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.
Is Inkling good for knowledge and understanding?
Inkling ranks #62 out of 181 eligible models for knowledge and understanding, with a public category score of 54.5/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Inkling good for coding and programming?
Inkling ranks #80 out of 149 eligible models for coding and programming, with a public category score of 34/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Inkling good for mathematics?
Inkling ranks #11 out of 12 eligible models for mathematics, with a public category score of 58.3/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Inkling good for agentic tool use and computer tasks?
Inkling ranks #72 out of 124 eligible models for agentic tool use and computer tasks, with a public category score of 36.2/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Inkling good for multimodal and grounded tasks?
Inkling ranks #35 out of 54 eligible models for multimodal and grounded tasks, with a public category score of 67.5/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Inkling good for instruction following?
Inkling ranks #35 out of 128 eligible models for instruction following, with a public category score of 87.6/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is Inkling open source?
Inkling is an open-weight model from Thinking Machines Lab. Its weights can be downloaded for local or hosted deployment, subject to the published license. Open weight does not automatically mean open source: training data and training code may remain private, and commercial restrictions can still apply.
Which sibling models are related to Inkling?
Inkling belongs to the Inkling family. Related tracked variants include Inkling-Small. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.
Does Inkling have full benchmark coverage on BenchLM?
No. Inkling currently has 49 source-displayable rows across 670 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Inkling?
Inkling has a reported context window of 1M in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
