What Trinity-Nano-Block is

src="https://cdn-uploads.huggingface.co/production/uploads/6435718aaaef013d1aec3b8b/i-v1KyAMOWmgVGeic9WJ.png" alt="Arcee Trinity Nano Preview" style="max-width: 100%; height: auto;" Trinity Nano Preview FP8-Block Trinity Nano Preview is a preview of Arcee AI's 6B MoE model with 1B active parameters. It is the small-sized model in our new Trinity family, a series of open-weight models for enterprise and tinkerers alike. This is a chat tuned model, with a delightful personality and charm we think users will love. We note that this model is pushing the limits of sparsity in small language models with only 800M non-embedding parameters active per token, and as such may be unstable in certain use cases, especially in this preview. This is an experimental release, it's fun to talk to but will not be hosted anywhere, so download it and try it out yourself! Trinity Nano Preview is trained on 10T tokens gathered and curated through a key partnership with Datology, building upon the excellent dataset we used on AFM-4.5B with additional math and code. Training was performed on a cluster of 512 H200 GPUs powered by Prime Intellect using HSDP parallelism. More details, including key architecture decisions, can be found on our blog here This repository contains the FP8 block-quantized weights of Trinity-Nano-Preview (FP8 weights and activations with per-block scaling).

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys trinity-nano-block for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (trinity-nano-block below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/chat/completions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"trinity-nano-block","messages":[{"role":"user","content":"Hello"}]}'

Licence

Commercial licence needed

The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
