What Inkling-Small is

Read our How to Run Inkling Guide! Inkling 1. General Information Inkling-Small is a general-purpose multimodal model that accepts text, image and audio inputs and generates text outputs. It is intended for use in English and other languages, and across multiple coding languages. The model is designed to be used by developers building AI-powered applications, including agentic and tool-use systems, coding assistants, chatbots, and retrieval-augmented generation systems, and is suitable for general-purpose conversational use, instruction-following, and other natural language and multimodal tasks. It is released with open weights to support research, fine-tuning and integration into third-party products by downstream developers. Languages: English, with general multilingual capabilities across other languages. 2. Getting Started Try Inkling-Small on the Tinker Playground or access via API using the Tinker Cookbook. Inkling-Small supports local deployment using the following open-source libraries: SGLang (recipe) vLLM (recipe) TokenSpeed (recipe) Unsloth (recipe) Huggingface (recipe) API access is also available through third party inference providers. 3. Model Properties Model type Multimodal autoregressive transformer Architecture type A 42-layer decoder-only transformer with a sparse Mixture-of-Experts (MoE) feed-forward backbone: each token is routed to 6 of 256 experts, plus 2 shared experts active on every token. Attention is a hybrid of local and global layers. The model is natively multimodal — images are encoded via a hierarchical patch encoder, and audio via discrete token encoding — with all modalities projected into a shared hidden space and processed jointly by the decoder. Parameters 276B total, 12B active Numerics support BF16 and NVFP4 Input modalities Inkling-Small accepts text, image, and audio inputs: - Text: UTF-8 encoded text - Image: Any pixel-based image input. For optimal performance, each image dimension should be between 40px to 4096px. - Audio: WAV format, sampled at 16kHz. For optimal performance, audio length should ideally be under 2 mins. Output modalities Inkling-Small generates output as UTF-8 encoded text. 4. Training Training data

Sizes & precisions

Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys inkling-small for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (inkling-small 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":"inkling-small","messages":[{"role":"user","content":"Hello"}]}'
