Subject: [PATCH 01/23] feat: add multi-provider LLM support with litellm

- Replace anthropic SDK with litellm for universal LLM support
- Add support for 8 major providers: Anthropic, OpenAI, Google, Groq, Azure, Cohere, Together AI, Mistral
- Update wizard to let users select provider before entering API key
- Add AI_PROVIDER and AI_MODEL config options
- Simplify AI client code from 647 to 628 lines
- Maintain backwards compatibility with existing ANTHROPIC_API_KEY setups
- Update README with all supported providers

    - Install [plugin](https://github.com/coddingtonbear/obsidian-local-rest-api) in Obsidian
    - Copy the API key from plugin settings
 
-2. **Anthropic API key:**
-   - Get from [console.anthropic.com](https://console.anthropic.com/)

Subject: [PATCH 02/23] refactor: focus on model choice instead of provider
 choice

- Update wizard to ask for MODEL (Claude 4, GPT-4o, etc.) not provider
- Add 8 popular model choices with human-friendly names
- Simplify README - remove exhaustive provider list
- Update litellm to >=1.8.0
- Add DeepSeek V3 as model option
- Remove custom model prompt (can use config if needed)

Subject: [PATCH 06/23] feat: allow setting model via human-friendly names

Users can now do:
  oki config set model "Claude Sonnet 4"
  oki config set model "GPT-5"
  oki config set model "Gemini 3 Pro Preview"

Instead of having to set ai_provider and ai_model separately with technical names.
The config command automatically maps human names to provider + model.

 ai_provider/ai_model)

- Replace AI_PROVIDER and AI_MODEL with single MODEL config
- Users now only see human-friendly names like "Claude Sonnet 4"
- Model mapping handled internally by FlashcardAI
- Backwards compatible with old configs
- Cleaner config output (just 'model: Claude Sonnet 4')

Subject: [PATCH 14/23] fix: add questionary mocking to setup tests and fix
 model_choice bug

- Add mock for questionary.select() in test_setup.py to fix EOFError
- Initialize model_choice=None in wizard.py to prevent UnboundLocalError
- Only set MODEL in config if model_choice was set during setup
- All 5 setup tests now pass (test_setup.py)
- 179/180 total tests passing

Subject: [PATCH 15/23] fix: reload command modules in mock_services to fix
 test mocking

The test_deck_list failure was caused by command modules holding
stale references to service objects. When deck_cmd.py imports ANKI
at the top level, it creates a reference before the mock_services
fixture can replace it.

Solution: Reload all modules that import from services after setting
up mocks, so they pick up the mocked instances instead of the originals.

- Reload deck_cmd, config_cmd, stats_cmd, schema_cmd, edit_mode
- All 180 tests now pass

Subject: [PATCH 17/23] test: add multi-provider feature test coverage

Added 11 tests to verify multi-provider LLM functionality:

TestModelMap (6 tests):
- Verify all 8 expected models exist in MODEL_MAP
- Ensure each model has required fields (provider, model, key_name)
- Validate Anthropic models use correct provider/API key
- Validate OpenAI models use correct provider/API key
- Validate Google models use correct provider/API key
- Validate DeepSeek models use correct provider/API key

TestFlashcardAIModelSelection (2 tests):
- Verify FlashcardAI defaults to Claude Sonnet 4.5
- Verify FlashcardAI respects CONFIG.model for different providers

TestModelConfiguration (2 tests):
- Verify all MODEL_MAP keys are user-friendly names
- Ensure no technical IDs like "claude-sonnet-4.5-20250514"

TestBackwardsCompatibility (1 test):
- Verify ANTHROPIC_API_KEY still works with new system

All 191 tests now pass (180 original + 11 new)

Subject: [PATCH 18/23] fix: standardize tool_choice format for different LLM
 providers

GPT-5 and other OpenAI models don't accept the nested format
`{"type": "function", "function": {"name": "..."}}` that Anthropic uses.

Changes:
- Add _get_tool_choice() helper method that returns provider-specific format
- Anthropic: {"type": "function", "function": {"name": "..."}}
- OpenAI/Google/DeepSeek: {"type": "function", "name": "..."}
- Replace all 5 hardcoded tool_choice calls with helper method
- Simplify "auto" tool_choice from {"type": "auto"} to "auto"

Fixes "Unknown parameter: 'tool_choice.function'" error with GPT-5

Subject: [PATCH 21/23] fix: add proper type annotations to ai/client.py

- Import Optional, Union, ModelResponse types
- Add return type annotations to all methods:
  - _validate_api_key() -> None
  - _get_tool_choice() -> str
  - _call_llm() -> Optional[ModelResponse]
- Fix _call_llm parameter types:
  - tools: List[Dict[str, object]] (more specific than Dict)
  - tool_choice: Union[str, Dict[str, object]] (can be "auto"/"required" or dict)
- Fix mutable default arguments in generate_flashcards and generate_from_query:
  - previous_fronts: Optional[List[str]] = None
  - deck_examples: Optional[List[Dict[str, str]]] = None

No use of Any type - all types are properly specified

Subject: [PATCH 23/23] fix: use cast() to handle ModelResponse vs
 CustomStreamWrapper typing

LiteLLM's completion() returns Union[ModelResponse, CustomStreamWrapper]
but we never use streaming (stream parameter defaults to False). Use
cast(ModelResponse, ...) to tell type checker the actual runtime type.

Fixes type error: 'ModelResponse | CustomStreamWrapper' is not assignable
to 'ModelResponse | None'
