Motif 3 is a chat model from Motif Technologies. It accepts text as input and returns text, with a context window of up to 262K tokens.

Core Capabilities of Motif 3
Up to 262K tokens of context
Keep long conversations, large documents and sizeable code in a single request, so the model can reason over the full material instead of fragments.
Reasoning mode
Motif 3 can produce reasoning before its final answer; in the Playground you can switch reasoning on or off to compare results.
Structured outputs
Ask for JSON that follows a schema (response_format), which makes extraction, classification and system integrations more reliable.
