Adds a Wally component bundle to Langflow, mirroring the OrcaRouter and OpenRouter bundles. Wally serves open-weight models (DeepSeek V4.1 Flash, GLM-5.3 Flash, Kimi K3, MiniMax M3 and others) through an OpenAI-compatible API, so the component reuses Langflow's ChatOpenAI-based language-model path and only sets the endpoint.
What this changes
New wally bundle (src/bundles/lfx-bundles/src/lfx_bundles/wally/): WallyComponent, an LCModelComponent with:
an API Key input and a Model dropdown whose options are fetched live from https://inference.runanywhere.ai/v1/models,
lfx-bundles extra: wally = ["langchain-openai>=1.1.6"], added to the all and all-no-torch aggregates, with the lfx-bundles version bump and uv.lock update.
Frontend icon: src/frontend/src/icons/Wally/, registered in lazyIconImports.ts and SIDEBAR_BUNDLES.
Migration table and release inventory entries for the new bundle.
Docs: new docs/docs/Components/bundles-wally.mdx page, registered in the sidebar and the bundle lists.
How to use
Add the Wally component to a flow, paste your API key from https://console.runanywhere.ai, and pick a model from the live catalog (e.g. deepseek-v4.1-flash). Or use the OpenAI Compatible model provider with base URL https://inference.runanywhere.ai/v1.

Adds the wally dependency extra and includes it in aggregate extras. Adds WallyComponent, which fetches and sorts model records, updates model options, and builds ChatOpenAI after validating the API key and model. Adds lazy component export, release inventory, and migration mapping entries.
langflow-ai/langflow#15983: Adds another OpenAI-compatible text-generation component to lfx-bundles, with related dependency, documentation, icon, and migration wiring.

Merge Risk: Low · previous review 2d42c
The Wally bundle works for the normal case. Model refresh can fail on unusual API responses or network errors, and a failed refresh can leave a bad model name selected. The bundle list page also carries a stale version statement. These are small fixes that can be made before or shortly after merge.

Explanation
The title "feat: add Wally bundle component" matches the main change. The PR adds a WallyComponent, a Wally bundle in lfx-bundles, its dependency extra, icon, docs, and registry entries. The title is short, specific, and follows the conventional commit style. It does not describe any unrelated work.

Explanation
Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 7 files. (8 skipped: 8 unsupported.)
Full details: Test File Naming And Structure
Explanation
The pull request adds no test files and changes no existing test files. Therefore, no backend, frontend unit, or Playwright test file violates the required naming or directory patterns. Existing repository examples use the stated pytest and frontend test layouts. The requested test-structure check is not applicable to these changes.
Full details: Test Coverage For New Implementations
Explanation
The PR adds WallyComponent in src/bundles/lfx-bundles/src/lfx_bundles/wally/wally.py, including fetch_models, update_build_config, and build_model, but the authoritative PR file list contains no test files. Existing bundle tests use test_*.py, and comparable component tests cover model-fetch and configuration behavior. The PR therefore does not include tests for the new functionality.
Resolution
Add test_*.py tests for Wally model fetching, sorting and request/status failures; build-config success and failed-load behavior; API-key/model validation; and ChatOpenAI arguments, including temperature and max tokens. Add an integration test for the component completion path when the repository's integration-test setup permits it, using mocked or controlled service responses.
Full details: Test Quality And Coverage
Explanation
The pull request adds WallyComponent and its model-list API path, but it adds no tests. The changed-file inventory contains no test file. Therefore, the main behaviors are unverified: successful model fetching and sorting, httpx.RequestError and HTTP-status failures, build-config updates, API-key/model validation, and exact ChatOpenAI construction. The contributor's reported manual calls are not automated behavior tests. No Wally async function requires async-specific testing.
Resolution
Add pytest coverage for WallyComponent. Mock httpx.get and test a successful response plus RequestError and HTTP-status error responses. Assert URL, timeout, filtering, fallback names, sorting, and empty/error handling. Test both update_build_config branches. Mock ChatOpenAI and assert endpoint, key, model, temperature, and max-token arguments, including validation failures and zero/None token cases. Add frontend component coverage with the project's React Testing Library pattern if the icon registration is in scope.

Align the page version with the new bundle entry.
This row adds Wally to a page whose introduction says the list reflects Langflow 1.13.0. The reviewed revision declares Langflow 1.14.0, so the page is internally inconsistent. Update that introduction to 1.14.0 or remove the version-specific claim. (raw.githubusercontent.com)

m.get("context_length", 0) returns None when a record contains "context_length": null. Line 66 then formats that value with :,, which raises TypeError. The exception leaves update_build_config because the except in fetch_models only handles httpx errors. The model list refresh fails for every model, not only the affected one. If the endpoint returns a null context length for any model, the dropdown cannot refresh.
Use 0 for a missing or null value, which matches the existing default for a missing key:

Preserve the selected model when refresh fails.
A timeout or HTTP error replaces the selected model with "Failed to load models". build_model() accepts that value and sends it as a model ID. A later successful refresh does not restore the selection.
Keep the existing selection on refresh failure and report the error separately.
