# Changelog

## v0.1.8

- Version bump; pin Burrito OTP build version to 28.5.0 to fix macOS binary builds.

## v0.1.7

- Version bump to stay in sync with the monorepo release; no functional changes.

## v0.1.6

- Drop `:custom_openai`, `:ollama`, and `:llama_cpp` providers — public provider
  atoms are now `:anthropic | :openai | :google` only
- `:openai` with `base_url` set routes to the OpenAI-compatible adapter (previously
  required `:custom_openai`); without `base_url` routes to the standard OpenAI path
- `identifier` defaults to `"OPENAI"` on `:openai` models when nil — resolves
  `OPENAI_API_KEY` for local endpoints that don't need a key
- `Planck.AI.Models.OpenAI.all/1` now accepts a `base_url:` opt to query a custom
  server's `/models` endpoint; without it returns the LLMDB catalog as before
- `Planck.AI.Models.CustomOpenAI`, `Planck.AI.Models.Ollama`, and
  `Planck.AI.Models.LlamaCpp` removed — superseded by `:openai` + `base_url`
- `Planck.AI.Model` gains `model` field — the actual provider model identifier
  (e.g. `"claude-sonnet-4-6"`); `id` becomes the user-facing alias. The adapter
  uses `model || id` so structs without the new field keep working
- `Planck.AI.Model` gains `has_api_key: boolean()` (default `true`); when `false`,
  the adapter passes `"not-needed"` directly and skips env-var lookup — for local
  servers like Ollama that require no authentication
- `Planck.AI.Config` functions `from_map/1`, `from_list/1`, and `load/1` removed — superseded
  by `from_config/2`
- `Planck.AI.Config.from_config/2` added — builds `[Model.t()]` from a providers
  map (user-keyed, each entry has a `"type"` field) and a models list (each entry
  references a provider key); this is the v0.1.6 config format

## v0.1.5

- New `:custom_openai` provider for OpenAI-compatible endpoints (NVIDIA, Together, vLLM, etc.)
- `Planck.AI.Model` gains an `identifier` field — a short uppercase tag (e.g. `"NVIDIA"`) used to derive the env var `<IDENTIFIER>_API_KEY` at request time
- `Planck.AI.Models.CustomOpenAI` — factory (`model/2`) and runtime discovery (`all/1`) via `GET {base_url}/models`
- `Planck.AI.Config` `from_map/1` validates and upcases `identifier`; rejects values that don't match `[A-Z][A-Z0-9]*`
- API keys for `:custom_openai` are resolved lazily from the environment at request time, never cached

## v0.1.4

- Version bump to stay in sync with the monorepo release; no functional changes.

## v0.1.3

- Version bump to stay in sync with the monorepo release; no functional changes.

## v0.1.2

- Version bump to stay in sync with the monorepo release; no functional changes.

## v0.1.1

- `ex_doc` bumped to `~> 0.40.2`; no functional changes.

## v0.1.0

First release.

- Provider-agnostic streaming and completion API over `req_llm`
- Lazy event-tuple stream (`{:text_delta, _}`, `{:thinking_delta, _}`, `{:tool_call_complete, _}`, `{:done, _}`, `{:error, _}`)
- Tool calling with streaming argument assembly
- Model catalog for Anthropic, OpenAI, and Google via LLMDB
- Local server support for Ollama and llama.cpp with runtime model discovery
- JSON config loader (`Planck.AI.Config`)
- Multimodal input: text, image, image_url, file, video_url
- `parse_provider/1` (private) — `String.to_existing_atom` →
  `String.to_atom`; `@valid_providers` derived from `Planck.AI.list_providers()`
  at compile time (single source of truth). Private function specs added.
