Open weights

Vector 1 — open-weight models, built to assist teachers.

Vector is MikaLabs' family of open-weight models built to assist teachers — not students. Post-trained to produce the materials educators make over and over: differentiated worksheets, mark schemes, misconception guides, lesson plans and pitched explanations across maths and the sciences. Apache 2.0, and small enough to run locally and offline.

The family

Four models, one pedagogy.

A family released under a permissive license — weights, tokenizer, and model card in the open. Rolling out one model at a time.

Open weights

“Light, version 1” — the first and smallest Vector model. Compact enough to run locally and offline on modest consumer hardware, with quantized GGUF builds included.

What it does

Built to make classroom materials.

Vector is specialised for the resources teachers produce again and again — the work, not the chat.

ADifferentiated worksheets

Multi-tier support / core / extension sets with genuine difficulty progression — not the same questions relabelled.

BExam-style mark schemes

Method marks (M) and answer marks (A) shown separately, the way real exam marking actually works.

CMisconception guides

The specific, subject-level errors students make on a topic — each listed alongside how to address it.

DStructured lesson plans

Objectives, starters, main activities and plenaries, laid out ready to take straight into a classroom.

EMixed-format questions

Short answer, true/false with justification, fill-in-the-blank, calculation and explain-your-reasoning — never defaulting to multiple choice.

FHolds the brief

Follows complex, multi-part instructions, pitches difficulty to the age or ability you name, and returns clean, ready-to-use output.

Vector is a specialist, not a general chatbot — it isn't built for coding, open-ended chat, or subjects beyond maths and the sciences, and high-stakes assessment should always have a teacher reviewing the output. Full weights and model card live on Hugging Face.
