Scores come from live data — output price (cost), context length, open vs closed weights (openness & self-hosting) and vision/tool support (multimodality). Raw task quality isn't scored here; it depends on your benchmark — see the verdict.
Inkling Small is an open-weight multimodal mixture-of-experts model from Thinking Machines Lab, with 12B active parameters out of 276B total. It is positioned as the smaller, more efficient member of...
Aion-RP-Llama-3.1-8B ranks the highest in the character evaluation portion of the RPBench-Auto benchmark, a roleplaying-specific variant of Arena-Hard-Auto, where LLMs evaluate each other’s responses. It is a fine-tuned base model...
These variants are tracked but not compared here — one page per family keeps the comparison readable.
Inkling Small is open-weight and competitive on many tasks, but Aion-RP 1.0 (8B) may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.
Yes. Inkling Small has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. Aion-RP 1.0 (8B) is API-only and cannot be self-hosted.
Choose Inkling Small if you want to self-host, keep your data private and skip per-token fees — it's open-weight and runs on your own hardware. Choose Aion-RP 1.0 (8B) if you want frontier capability through a managed API with zero infrastructure to run.
