providers becomes a dict keyed by provider route, so the composition base and the llm-pi-ai settings section merge per provider and the route set is structural; the pre-release array shape and per-profile provider field fail loud with migration directions. The adapter reads a profiles thunk once per operation and resolves the credential per stream call (literal apiKey, then apiKeyEnv through ctx.credentials with an ambient env fallback, then pi-ai's provider-native discovery), so key, endpoint, and knob changes reach the next request without restarts. Route-set or captured-retry-policy changes re-register the same adapter instance in one synchronous section; an invalid settings snapshot keeps the last good profiles.
llm/ — LLM capability family
English | 中文
The LLM seam and its provider adapters. The interface package (llm) owns the abstract service, the content-block vocabulary, and the stream-chunk assembler; the adapters are concrete implementations that register on ctx.llm. All product packages.
| Package | Role | ctx key |
|---|---|---|
llm/ |
Abstract LLM service + content-block vocabulary + chunk assembler | ctx.llm |
token-meter/ |
Replay-aware request and surface token measurement | ctx.tokenMeter |
llm-retry/ |
Exact-provider normal or unbounded request retry policy | (listens to agent/request-error) |
llm-deepseek/ |
DeepSeek API adapter (direct fetch + eventsource-parser SSE) | (registers on ctx.llm) |
llm-pi-ai/ |
Multi-provider adapter via @earendil-works/pi-ai |
(registers on ctx.llm) |
The interface lives at llm/llm/; adapters, retry policy, and the reusable token meter are flat siblings under the group. Requests route by provider, while model is passed through to the selected adapter. The route-owning adapter supplies retry policy and resolves available exact-model identity, context capacity, and reasoning metadata; the retry executor and token meter remain provider-agnostic. A new provider adapter registers one or more provider routes on ctx.llm without touching the consumers. See twin LLM adapters for the two shipping implementations, the replay token meter Agent Note for measurement ownership, and the routed model context Agent Note for capacity and compaction-policy ownership.
