`CohereReranker` and `VoyageAIReranker` read the environment variable before the `api_key` argument. When `COHERE_API_KEY` or `VOYAGE_API_KEY` is set, the reranker ignores an explicit `api_key` and uses the account from the environment. The docs say the opposite. `docs/web/integrations/reranking/cohere.mdx` and `voyageai.mdx` use the environment variable only when `api_key` is not provided. `JinaReranker` and `WatsonxReranker` already put the explicit key first, and #4515 makes the same change for `OpenaiReranker`. ## Fix `CohereReranker._client` and `VoyageAIReranker._client` now use `self.api_key` first and the environment variable as the fallback. ## Tests `python/python/tests/test_reranker_credentials.py` replaces the SDK module with a stub whose `Client` records the API key. It covers both keys set, each key alone, and no key. With the stub, the test runs without `cohere` or `voyageai` installed. - On `main`, the 2 cases with both keys set fail and the other 6 pass. With the fix, all 8 pass. - `test_rerankers.py` with the new file: 24 passed, 13 skipped (the skipped tests need real API keys). - `ruff format --check` and `ruff check` (0.9.9) pass on the changed files. - I did not build the native extension. I ran the tests against the lancedb 0.40.0 wheel with the changed files copied over it. In that wheel, both reranker files are byte-identical to `main` before this change.
