Learning: In PyOpenGL, bare Python scalars can be accepted for 1-element array parameters by NumberHandler. This means you can pass an int/float directly to OpenGL texture deletion (e.g., glDeleteTextures(tex)) without wrapping in a list. Verify function-specific expectations and ensure types match what the OpenGL call expects; use explicit lists only when the API requires an array.

Learning: In `comfy_api_nodes` Python async node implementations (e.g., `async def execute`), synchronous CPU/IO-heavy helpers (such as video/audio trim/resize and base64/MP3 conversion) may be called directly without offloading to a thread executor (e.g., `asyncio.to_thread`). Treat this as an existing, broader refactor concern rather than a new PR regression: if the PR does not introduce additional synchronous blocking calls, reviewers should not flag it as a new issue. However, if the PR adds new synchronous CPU/IO work inside `async def execute`, prefer offloading with `asyncio.to_thread` (or an equivalent background executor) to avoid blocking the event loop.

Learning: In ComfyUI node implementations under `comfy_api_nodes/`, when building JSONata expressions that use `IO.PriceBadge` for `$lookup` against a price map keyed in lowercase, do not add an explicit `$lowercase()` around widget values (e.g., combo options like "1K", "2K", "4K"). The ComfyUI frontend automatically lowercases widget values before evaluating the JSONata expression, so the lookup keys will already match the lowercase map entries.

Timestamp: 2026-07-14T20:09:03.091Z
Learning: In the `comfy_api_nodes/` package, partner/API node `execute` implementations should keep the full submit → poll → status-check → download flow written inline within each node (even if similar logic appears across multiple nodes). This is an intentional repo convention to optimize per-node readability and independent editability, so during reviews you should generally not recommend refactoring this pattern into a shared helper function for these nodes (unless there’s a concrete correctness/security issue).

Learning: When implementing ComfyUI API nodes in this repo, for any billable HTTP POST operations, follow the established policy: keep the existing default retry behavior. Do not add idempotency keys or disable retries. The rationale is to prevent failures from aborting the entire workflow; when reviewing new API nodes, check that POST billing requests preserve the default retry configuration and remain consistent with this policy.

Learning: When consuming dictionaries produced by IO.Autogrow.Type, rely on their iteration order to match the configured template-slot order. This ordering is preserved by _expand_schema_for_dynamic, parse_class_inputs, and build_nested_inputs, so consumers should iterate the dictionary directly when processing dynamic slots.

Learning: When reviewing ComfyUI nodes that use IO.DynamicCombo, account for schema expansion by comfy_api/latest/_io.py::DynamicCombo._expand_schema_for_dynamic. Prompt validation in execution.py validates each resulting IO.Combo value against extra_info["options"] and rejects invalid values with value_not_in_list before execute() runs. Review validation logic against only the reachable option domain for closed IO.Combo.Input lists inside a DynamicCombo, unless the node provides another input path that bypasses prompt validation.

Learning: In ComfyUI API node implementations, treat saved `widgets_values` as positional. When renaming or changing the type of a widget input, do not rely on backend `execute()` to migrate legacy values, because prompt validation may reject the value before execution. Implement compatibility handling in the frontend or workflow/template migration layer so legacy workflows are converted before backend validation.

Learning: In partner nodes under comfy_api_nodes, do not flag direct calls from async def execute to shared audio/video conversion helpers such as audio_bytes_to_audio_input, audio_ndarray_to_bytesio, or audio_tensor_to_contiguous_ndarray as individual regressions. If event-loop offloading is needed, implement it centrally in the shared helpers under comfy_api_nodes/util as a dedicated refactor, preserving clean call sites across partner nodes.

Learning: In Python partner API nodes under comfy_api_nodes/, keep each node’s execute body self-contained, including input validation and the submit → poll → status-check → download flow. Do not extract duplicated validation into shared helpers when limits are endpoint-specific or model-version-specific, because vendor constraints may diverge; preserve per-node readability, independent editability, and a limited blast radius.

595-595: 🗄️ Data Integrity & Integration

Verify the model identifier before release.

This change routes the new selector value to gemini-3.7-flash. As of August 18, 2026, Google's public model documentation lists Gemini 3.6 Flash but does not list Gemini 3.7 Flash. Confirm that /proxy/vertexai/gemini accepts this exact identifier or translates it to a supported backend model. (ai.google.dev)

Source: MCP tools


698-701: 🗄️ Data Integrity & Integration

Verify sampling fields for the new model.

When this option is selected, execute() still sends temperature and top_p at Lines 803-804. Google documents these fields as deprecated for Gemini 3.6 and future model generations, and future models can reject requests that include them. Confirm that the proxy removes them for Gemini 3.7 Flash or omit them at this integration boundary. (ai.google.dev)

Sources: Path instructions, MCP tools


747-751: 🗄️ Data Integrity & Integration

Verify the pricing metadata against the billing rate card.

The badge displays $0.00215–$0.01073 per 1K tokens. Confirm these values against the Metronome rate card and auto-billing tests before release. The current public Google model documentation does not provide Gemini 3.7 Flash pricing. (ai.google.dev)

As per path instructions: AGENTS.md requires accurate pricing and verification of selector and pricing behavior.

Walkthrough

Added Gemini 3.7 Flash to the V2 model mapping and dynamic text model selector. Added LOW, MEDIUM, and HIGH thinking levels. Added token pricing metadata of $0.00215–$0.01073 per 1K tokens.

Learning: When reviewing ComfyUI nodes that use IO.DynamicCombo, account for schema expansion by comfy_api/latest/_io.py::DynamicCombo._expand_schema_for_dynamic. Prompt validation in execution.py validates each resulting IO.Combo value against extra_info["options"] and rejects invalid values with value_not_in_list before execute() runs. Review validation logic against only the reachable option domain for closed IO.Combo.Input lists inside a DynamicCombo, unless the node provides another input path that bypasses prompt validation.

Learning: In ComfyUI API node implementations, treat saved `widgets_values` as positional. When renaming or changing the type of a widget input, do not rely on backend `execute()` to migrate legacy values, because prompt validation may reject the value before execution. Implement compatibility handling in the frontend or workflow/template migration layer so legacy workflows are converted before backend validation.

Learning: In partner nodes under comfy_api_nodes, do not flag direct calls from async def execute to shared audio/video conversion helpers such as audio_bytes_to_audio_input, audio_ndarray_to_bytesio, or audio_tensor_to_contiguous_ndarray as individual regressions. If event-loop offloading is needed, implement it centrally in the shared helpers under comfy_api_nodes/util as a dedicated refactor, preserving clean call sites across partner nodes.

Learning: In Python partner API nodes under comfy_api_nodes/, keep each node’s execute body self-contained, including input validation and the submit → poll → status-check → download flow. Do not extract duplicated validation into shared helpers when limits are endpoint-specific or model-version-specific, because vendor constraints may diverge; preserve per-node readability, independent editability, and a limited blast radius.

595-595: 🗄️ Data Integrity & Integration

Verify the Gemini 3.7 provider contract before merge.

If gemini-3.7-flash is not the exact identifier accepted by GEMINI_BASE_ENDPOINT, requests using this option will fail. Confirm the identifier with the Comfy proxy.

Also confirm that this model supports LOW, MEDIUM, and HIGH, the shared temperature, top_p, and max_output_tokens inputs, and the $0.00107$0.00536 per-1K-token price badge. The official Google material I checked documents Gemini 3.6 Flash, states that capability support varies by model, notes unsupported sampling parameters for some Flash models, and includes thinking tokens in output pricing. It does not establish this new identifier or rate. (ai.google.dev)

As per path instructions, AGENTS.md requires model metadata to remain consistent with the provider’s expected identifiers and capabilities.

Also applies to: 698-701, 747-751
