Structured rows reported in this exact model repository at the pinned revision below. They are the publisher talking about itself: never measured evidence, never a score input on their own. They remain quarantined until dataset revision, harness, configuration and identity pass ModelCap’s independent admission review.

Granite 4.2 8B: common questions

How does Granite 4.2 8B rank among AI models?

Granite 4.2 8B holds ModelCap Index position #240 of 351 ranked language models as of 18 October 2026, with an Index score of 26.6 (interval 20.3–32.9); evidence: measured. The Index combines public benchmark boards with published uncertainty; the methodology page explains the weighting.

How much does Granite 4.2 8B cost per 1M tokens?

Granite 4.2 8B is listed at $0.06 per 1M input tokens and $0.25 per 1M output tokens as of 18 October 2026; the lowest output price among 2 providers is $0.15 on CoreWeave. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $0.245 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.

What is the context window of Granite 4.2 8B?

Granite 4.2 8B has a published context window of 131K tokens (131,072). The snapshot lists a 117,964 token catalogue-declared route output cap. OpenRouter catalogue or provider-endpoint declaration. Limits can vary by provider and prompt length; a model-wide maximum has not been independently verified. The providers table lists each endpoint's context limit.

Is Granite 4.2 8B open-weight?

Open weights (apache-2.0). Downloadable weights are published under an OSI or free-culture license in the current repository metadata. This describes weight availability, not whether the full training stack qualifies as Open Source AI. The repository is ibm-granite/granite-4.2-8b on Hugging Face.
