August 3, 2026: native MiniMax H3 support changes how older API guides should be labeled

Event and date

This is a dated maintenance note about Comfy's August 3, 2026 Day-0 support announcement, not a claim that the event happened today.

Source-supported context

The announcement describes native open-weight H3 support and text, image and reference inputs. The current native-workflow guide documents the local T2V, I2V and R2V paths, so an old API-only statement needs a date and execution-context qualifier. Announcement Native workflows

Impact and scope

1. Existing API tutorials describe remote execution/account services, not every H3 use path.

2. Local guides need weight, core-version, audiovisual-VAE and directory details.

3. Historical hardware, speed and quality statements remain attributed claims rather than this site's benchmark results.

Maintenance steps

The sequence below is an editorial procedure based on the cited context, not a diagnosis already confirmed for your environment.

Step 1. Label older guides with their applicable date and local, hosted or Partner/API execution model.

Step 2. Link model identities to the native guide, distinguishing T2V/I2V and R2V resource choices.

Step 3. Maintain separate links for unregistered nodes, missing weights, attention dependencies and audio export.

Step 4. Update evergreen guides from current documentation while preserving the announcement's event date and recording later revisions separately.

Completion check

Readers can identify the execution route and outstanding files or permissions, without mistaking a historical limitation for a permanent fact.

Limitations and cautions

Promotional metrics, downloads and H3 execution were not independently tested here. An announcement is not a blanket commercial-use authorization; the current ComfyUI overview distinguishes commercial rights for locally generated outputs and cloud generations.
