Engrym Seed Base 9B

Orvyth's seed-tier brain — the recommended member of a local model family built for tool-using agents. Qwen3.5 hybrid linear-attention architecture, 262,144-token native context, first-class tool calling.

Weights are distributed via the Ollama registry.

The ladder

Evaluation

77 tasks · 143 points · temperature=0 · max_tokens=16384 · seed=42 · one attempt · deterministic validators · no LLM judge. Scores are bound to the exact published blobs.

These are first-party numbers. Repeated runs on an uncontended GPU are deterministic (zero spread across n=2 for every model measured), Receipts: https://huggingface.co/datasets/Orvyth/engrym-seed-receipts

Compute modes — the score above is a floor

Asking the model to work deliberately (reason step by step, verify against every constraint, then answer) recovers points on tasks it otherwise fails. Base: 131 → 134. The gain is largest for the smallest models — Nano gains +11.8. On the small end, that is worth more than a model upgrade.

Defaults

temperature 0.2 · top_p 0.9 · top_k 20 · num_ctx 32768 · num_predict 8192

Native context is 262,144; larger requests are clamped. Default is 32,768 because defaulting to the native maximum made a 9.5 GB model request ~19 GB of RAM to start. If a prompt exceeds num_ctx, Ollama returns HTTP 400 — it does not silently truncate.

Lineage

What is in the artifact

Weights, identity, and tool-call generation. Memory, governed tool execution, safety enforcement, adapters and multi-agent routing are Orvyth platform concerns, not part of the GGUF. Tool calling is an output capability — the host validates, authorizes and executes.

Limits

• Scores are first-party and single-suite. Treat small gaps between adjacent models as unresolved.
• The identity tune is light; under a heavy external system prompt behavior can defer to the base model.
• The 27B is substantially slower per tool call than the 9B. Prefer Base or Flash for agent loops.
• The MTP speculative-decoding head is not included in these builds.
• Tags are mutable — pin the digest for production and evaluations.
