StripedHyena Nous 7B is a hybrid SSM-transformer model — combining Hyena's efficient long-range sequence modeling with transformer layers for a fast, efficient alternative to standard attention.
StripedHyena Nous 7B is an AI model released December 2023 by togethercomputer, a leading organization in large language model research. Together AI × Nous Research StripedHyena 7B — Hyena/state-space hybrid architecture optimized for ultra-long-context document chat. With 7B and a 32K tokens context window, StripedHyena Nous 7B is designed to excel across a range of demanding tasks — from software engineering and mathematical problem-solving to multilingual content generation and long-document analysis.
StripedHyena Nous 7B uses a dense transformer architecture with 7B of parameters, all of which are active for every input token. Dense architectures provide predictable, consistent behavior across diverse task types — there are no "cold" experts to warm up, and quality is uniform across prompts. togethercomputer's training pipeline combined large-scale pretraining on a large-scale multilingual pretraining dataset with supervised fine-tuning and alignment techniques (RLHF or DPO), producing StripedHyena Nous 7B's characteristic balance of capability, helpfulness, and safety.
As of 2026-10-16, StripedHyena Nous 7B by togethercomputer demonstrates measurable performance on standard AI evaluation benchmarks. On MMLU — which tests world knowledge across 57 academic subjects from elementary to professional level — it achieves 58.5%. These scores place StripedHyena Nous 7B — at 7B of parameters — in a competitive position within its model class. Note that benchmark scores reflect controlled evaluation conditions; real-world performance varies by task, prompt design, and domain specificity.
The primary strengths of StripedHyena Nous 7B are: Novel hybrid SSM architecture — not a transformer; Linear computation scaling with sequence length; Apache 2.0 — free. These make it particularly well-suited for Research on alternative architectures to transformers, Long-sequence tasks where transformer quadratic complexity is limiting. Users working on complex, multi-step problems benefit most from StripedHyena Nous 7B's ability to maintain coherence across long inputs and produce structured, verifiable outputs.
Like all current AI systems, StripedHyena Nous 7B has limitations: Performance below same-size transformers; Requires custom inference tooling; Research model. For production deployments, validating outputs against authoritative sources — especially for domain-specific or time-sensitive information — remains best practice. togethercomputer continues to improve StripedHyena Nous 7B through ongoing research.
StripedHyena Nous 7B is available on LITHOVEX AI with a free account. Unlike direct API access — which requires billing setup, API key management, and per-token charges — LITHOVEX AI provides a seamless browser interface with no setup required, making StripedHyena Nous 7B accessible to students, researchers, developers, and early-stage teams globally.
