Stability AIStable LM

Stable LM 2 Chat 12B

Stable LM 2 Chat 12B is an English instruction-tuned model with documented function calling. Its training includes public instructions, synthetic data, safety data and preference optimization.

Research release

Model design and access

The model card describes a dedicated function-calling dataset alongside general instructions and safety data. The release requires compatible StableLM support in the inference library. Function-call generation produces structured requests; an application still owns execution and permission checks.Stable LM 2 Chat 12B official model card

Practical use

Practical guidance. Use this checkpoint to study local tool-selection behavior or to maintain an existing research workflow. Review malformed calls, missing arguments and short-context limits before connecting tools. A model's ability to request a function is separate from its ability to complete a multi-step task accurately.
