…dd thinking note The OpenRouter accordion in all four language versions of `concepts/llms.mdx` contained `api_key=OPENROUTER_API_KEY` — a bare Python variable reference that is never imported, causing a `NameError` for any user who copies the snippet verbatim. The `base_url` parameter was also hardcoded to the default value that the provider already sets automatically. Changes across docs/en, docs/ar, docs/pt-BR, docs/ko: - Replace `api_key=OPENROUTER_API_KEY` with comments explaining the auto-resolve behavior (reads from `OPENROUTER_API_KEY` env var; `base_url` auto-configured) - Add `from crewai import LLM` import to the example - Add extended-thinking example for OpenRouter + Anthropic models, noting the `thinking` param works for any LiteLLM-routed provider (now that the `_prepare_completion_params` forwarding bug is fixed) - Expand the model list to include `openrouter/anthropic/claude-sonnet-4-5` Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
