About
The SubQ model family from Subquadratic Inc. features a fully sub-quadratic sparse-attention architecture that scales linearly with context length (O(n) complexity). Designed for long-context reasoning, the family targets 12M-token context windows with significantly reduced compute costs vs. standard transformer-based models.

Frequently Asked Questions
- What is SubQ used for?
- SubQ is used for reasoning and agent workflows and tool use. The family description and listed model capabilities point to those workloads as the best fit.
- How does SubQ compare to Claude 3?
- SubQ by Subquadratic is strongest where you need reasoning, while Claude 3 by Anthropic is the closest related family to check for vision and multimodal work. SubQ has 1 listed variant and reaches up to 1M context, while Claude 3 reaches up to 200K context, so compare the specs and pricing tables before choosing a production model.
- Which SubQ model should I use?
- If price is the main constraint, use the pricing table first because SubQ does not have complete provider pricing in the local data. For the most capable/latest local choice, evaluate SubQ 1M-Preview with 1M context and reasoning, tool use, and function calling.
