Arcanum.ModelProfile (arcanum v0.1.0)

Copy Markdown View Source

Declares model capabilities upfront so adapters serialize correctly on the first attempt — no runtime detection, no retry-on-error branching.

Every model gets a profile. Unknown models get default/0 which assumes the weakest common denominator (no system role, XML text tool calls).

Summary

Types

t()
tool_call_format()

Functions

capable()

Profile for models with full OpenAI-compatible capabilities. GPT-4o, Claude via OpenAI proxy, etc.

default()

Default profile for unknown models. Assumes weak model capabilities. Safe for free-tier / community models that may reject system role and emit tool calls as XML text.
