Pricing detail. Qwythos (model ID: richardyoung/qwythos-9b-abliterated) is an abliterated build of empero-ai's Qwythos-9B-Claude-Mythos — a Claude-style creative & reasoning model on a Qwen3.5-9B base, post-trained on Claude Mythos & Fable traces, with a 1M-token context. Thinking model (<think>), native function-calling. Refusals trimmed via the Heretic library (53/100, KL 0.0066). Q4_K_M is 5.6GB, runs 100% offline.
How I use it inside the Agent OS. Loaded in Ollama alongside Ornith as the long-context local option. Bench results pending.
What I built with Qwythos 9B
Every model on Goldie Bench gets the same fixed prompt set — one shot, single HTML file out — and I score the result 0–10 inside the Agent Operating System. Here's what Qwythos 9B shipped on the bench: 0 one-shot demos across 1,048,576 tokens (YaRN, Qwen3.5-9B base) of context. Of those, 0 are scored against the field with my honest 0–10 from the source guides at agentos.guide.
Strengths
- Full 1M-token context locally — matches frontier-cloud models on context length, at $0
- Fast — ~3 tokens for 'pong' in 38ms during the smoke test
- Apache-2.0 license, runs entirely on-device via Ollama
Trade-offs
- 9B ceiling — won't match frontier 100B+ on complex one-shot ambitious builds
- Quality varies vs Ornith on the same prompts; bench scoring will land the honest number
Best for
- Long-context local tasks (large file refactors, multi-file analysis) where 1M ctx matters
- Cost-zero daily coding work on a consumer Mac
- Workflows where you want an unfiltered local coder without API guardrails
