Adds `lfx-atlascloud`, a standalone Langflow Extension Bundle for the Atlas Cloud gateway (https://api.atlascloud.ai/v1), with one chat-model component built on langchain_openai.ChatOpenAI. Follows the empiriolabs/novita/cometapi shape for an OpenAI-compatible host: the component reads the live catalog from /v1/models over requests and falls back to a bundled list. Two things are specific to this gateway: - /v1/models needs no authentication, so the model dropdown fills in before a key is entered; the key is still sent when present. - the catalog reports output_modalities ["text"] for its image and OCR models too, so those are filtered out of a chat-model dropdown by id rather than by that field. No migration_table.json entry: the component never shipped in-tree under lfx.components.atlascloud.*, so there is no legacy import path to rewrite.

WalkthroughThis change adds an Atlas Cloud extension bundle with a model component that retrieves and filters models, builds a LanguageModel, and supports JSON mode. It also registers the opt-in package and adds frontend icon, sidebar, and documentation entries. ChangesAtlas Cloud bundle

Suggested reviewers: Merge Risk: 🔵 Low · up to A malformed response from the model catalog endpoint could break the model dropdown refresh instead of showing the bundled list. This is a narrow edge case, and the rest of the bundle registration looks sound, so the change is low risk to merge. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The integration remains opt-in and uses a fixed external endpoint. However, when a deployment supplies its API key, automatic credential import can distribute that key to users without applying the provider-configuration authorization check. Persisted copies also require separate cleanup during rollback. Retained concerns

Format parameter and type identifiers as inline code.
The parameter names and types in this table are identifiers. Wrap them in backticks, such as api_key, SecretString, and LanguageModel.
As per coding guidelines, “Code: Inline code with backticks.”

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Validate the shape of the decoded /v1/models response.
response.json() can raise ValueError (requests.JSONDecodeError). In newer requests versions it subclasses RequestException, but with the declared floor requests>=2.32.0 it is only safe on versions where it does. response.json() can also return a non-dict value, such as a list or null. A non-dict value makes model_list.get raise AttributeError. Entries in data that are not dicts make model.get raise too. A non-string id makes model_id.lower() raise AttributeError.
Any of these errors propagates out of update_build_config instead of using the bundled fallback list. A gateway or proxy that returns an HTML or malformed body then breaks the dropdown refresh.
Check that the decoded value is a dict. Check that data is a list. Skip entries that are not dicts or that lack a string id.
Proposed fix
- except requests.RequestException as e:
+ except (requests.RequestException, ValueError) as e:
self.status = f"Error fetching models: {e}"
return MODEL_NAMES
- models = [
- model_id
- for model in model_list.get("data", [])
- if (model_id := model.get("id")) and not any(m in model_id.lower() for m in _NON_CHAT_MARKERS)
- ]
+ data = model_list.get("data") if isinstance(model_list, dict) else None
+ if not isinstance(data, list):
+ return MODEL_NAMES
+ models = [
+ model_id
+ for model in data
+ if isinstance(model, dict)
+ and isinstance(model_id := model.get("id"), str)
+ and model_id
+ and not any(m in model_id.lower() for m in _NON_CHAT_MARKERS)
+ ]
return models or MODEL_NAMESBased on learnings: validate that a decoded JSON value is a mapping before indexing into it.

Five of the seven ids in ATLASCLOUD_MODELS answered when this PR was opened and now return `400 not found` from the gateway, even though GET /v1/models still lists them: DeepSeek-V3.1, DeepSeek-V3.1-Terminus, GLM-4.6, glm-4.7 and Qwen3-235B-A22B-Instruct-2507. Replaced the fallback list and the default with deepseek-v4-flash, deepseek-v4-pro, glm-5.3-flash, glm-5.3, kimi-k2.6, qwen3.5-flash and minimax-m2.5. All seven were called against the live endpoint again just now; the 19 bundle tests, ruff check and ruff format still pass.

This component is routinely used as an Agent's LLM, and zai-org/glm-5.3-flash answers plain chat but returns `400 bad request` on every function-calling request (three for three), so it does not belong in the fallback list. Replaced with deepseek-ai/deepseek-v3.2. All seven ids in the list were re-checked against the live endpoint with a tools payload; the 19 bundle tests and ruff still pass.

What this adds
lfx-atlascloud, a standalone Extension Bundle for the Atlas Cloud gateway (https://api.atlascloud.ai/v1), with one chat-model component built onlangchain_openai.ChatOpenAI.It follows the
empiriolabs/novita/cometapishape for an OpenAI-compatible host: the component reads the live catalog from/v1/modelsoverrequestsand falls back to a bundled list.Disclosure: I work at Atlas Cloud. The endpoint is publicly reachable and
GET /v1/modelsneeds no key at all.Two things that are specific to this gateway
/v1/modelsis unauthenticated. The model dropdown fills in before a key is entered; the key is still sent when one is present.empiriolabs's version only works once a key exists.output_modalities: ["text"]for its image and OCR models too (openai/gpt-image-2,google/gemini-3-pro-image,deepseek-ai/deepseek-ocr), so that field cannot be used to keep them out of a chat-model dropdown. They are filtered by id instead, and if the filter were ever to empty the list the component falls back to the bundled one rather than showing nothing. Both paths have tests.Every id in the fallback list was checked against the gateway before being written down.
Testing
