Anthracite
1 model built
Anthracite is a community org on Hugging Face, not a funded lab — they're behind the Magnum series of roleplay fine-tunes built to mimic Claude-style prose. On OpenKey they show up with a single model: Magnum v4 72B, released October 22, 2024. There's no founding story or corporate backing to report here; this is a fine-tuning group with a specific niche (long-form roleplay and creative writing that reads like Claude's output) rather than a full model family strategy. If you want Claude-flavored prose without Anthropic's API, this is the whole catalog.
Lineup
There's no lineup to navigate — Magnum v4 72B is the only model Anthracite has on OpenKey, so it's both your cheapest and only option. It runs $3.00 per 1M input tokens and $5.00 per 1M output tokens (OpenKey price: $3.09 in / $5.15 out after the flat 3% fee), with a 32,768 token context window. Use it for roleplay and creative writing where you want Claude-like phrasing; look elsewhere if you need a large context window or a general-purpose reasoning model.

Questions
- What does Magnum v4 72B cost on OpenKey?
- $3.00 per 1M input tokens and $5.00 per 1M output tokens from the provider, plus OpenKey's flat 3% fee — that's $3.09 per 1M input and $5.15 per 1M output. It's the only Anthracite model available, so there's no range to compare it against.
- Is there a free Anthracite model?
- No. Anthracite has zero free models on OpenKey — the one model they offer, Magnum v4 72B, is paid at $3.00/$5.00 per 1M tokens (input/output).
- What is Magnum v4 72B good for?
- It's a fine-tune trained to mimic Claude-style prose, aimed at roleplay and creative writing. It has a 32,768 token context window and was released October 22, 2024. It's a niche pick, not a general-purpose model — go elsewhere for coding or long-context tasks.
