Hailuo 2.3 Fast: Complete Specifications, Pricing, API Access & Use Cases (2026)

What Is Hailuo 2.3 Fast?

Hailuo 2.3 Fast is MiniMax’s efficiency-focused image-to-video generation model, released with the Hailuo 2.3 family on October 28, 2025, supporting six- or ten-second 768p videos and six-second 1080p videos, with MiniMax API pricing starting at \$0.19 per video as of July 2026.

The Fast variant is designed for workflows that begin with a source image. MiniMax describes it as an image-to-video model focused on value and efficiency, distinguishing it from the standard Hailuo 2.3 model, which supports both text-to-video and image-to-video generation. Both Hailuo 2.3 variants support short video output at 24 frames per second.

As per the Gate.AI listing, the model is available under the identifier BAAI/hailuo-2.3-fast. This identifier is specific to Gate.AI. MiniMax’s provider API uses the separate model ID MiniMax-Hailuo-2.3-Fast.

Hailuo 2.3 Fast is not a language model. A token context-window value, including a "131K context" value, is therefore not an applicable model specification. Its relevant input constraints concern the source image, optional prompt, duration, resolution, and supported request parameters.

What Are Hailuo 2.3 Fast’s Key Specifications and Pricing?

Hailuo 2.3 Fast uses per-video pricing rather than input- and output-token billing. MiniMax lists three supported price combinations: \$0.19 for a six-second 768p video, \$0.32 for a ten-second 768p video, and \$0.33 for a six-second 1080p video.

The distinction between provider pricing and gateway pricing should be preserved. The figures above are verified on MiniMax’s pay-as-you-go page and match the prices in the Gate.AI listing supplied for this model. They should still be rechecked before publication because model prices can change.

What Can Hailuo 2.3 Fast Do That Makes It Useful in Production?

Animate an existing visual asset

Hailuo 2.3 Fast converts a starting image into a short video. This may fit product visuals, character artwork, campaign images, storyboards, illustrations, and social-media assets that already have an approved composition.

The generated clip remains dependent on the quality and clarity of the source image. Poorly defined subjects, small text, overlapping objects, or ambiguous anatomy may reduce consistency.

Generate lower-cost creative variations

The Fast variant costs less per generation than the standard Hailuo 2.3 model across the corresponding 768p and 1080p configurations. This can make it practical for testing several motion directions, camera treatments, or prompt variations before choosing a final clip.

Lower price does not guarantee an acceptable result on the first attempt. Production budgets should account for retries, rejected outputs, post-production, storage, and review.

Control camera movement with explicit commands

MiniMax documents 15 camera commands for supported image-to-video models. These include truck, pan, push, pull, pedestal, tilt, zoom, shake, tracking-shot, and static-shot controls.

Commands such as [Pan left], [Push in], or [Tracking shot] can make camera intent more explicit than free-form wording alone. MiniMax recommends no more than three simultaneous movement commands.

Choose between iteration and higher-resolution output

A six-second 768p clip is the lowest-priced configuration and may suit drafts or rapid testing. Ten-second output is available at 768p, while 1080p is limited to six seconds.

This structure supports short-form asset creation but does not replace a full editing workflow for longer sequences.

Integrate generation into asynchronous applications

Video generation is not an instant chat-style response. Applications submit a task and then retrieve its status, use a callback, or poll until the result is ready.

This pattern can support creative dashboards, asset queues, media-processing services, and campaign-production systems. It also requires reliable handling of failed tasks, timeouts, callback validation, expired media, and retry policies.

What Are Hailuo 2.3 Fast’s Supported Modalities?

MiniMax’s API documentation requires a source image for MiniMax-Hailuo-2.3-Fast and permits a prompt of up to 2,000 characters. Supported source files include JPG, JPEG, PNG, and WebP images below 20 MB.

Where Does Hailuo 2.3 Fast Fall Short?

The model’s primary limitation is its input mode. Hailuo 2.3 Fast is documented as image-to-video, so it is not the appropriate Hailuo 2.3 variant for a workflow that must begin from text alone.

Its clips are also short. Ten-second output is available only at 768p, while 1080p output is limited to six seconds. Longer narratives require multiple generations and editing, which can introduce continuity problems across shots.

Generated videos may contain object deformation, unstable anatomy, inconsistent faces, unwanted camera motion, changing backgrounds, or physically implausible movement. These are general generative-video risks and are not presented as unique defects of Hailuo 2.3 Fast.

Prompt adherence and identity consistency should be evaluated with representative source assets before deployment. A model that performs well on one visual style may behave differently on small products, typography, crowds, hands, reflective surfaces, or complex interactions.

Generated media also requires human review for copyright, trademark, privacy, consent, impersonation, misinformation, and brand-safety risks. It should not be treated as documentary evidence. Medical, legal, political, financial, or journalistic uses require qualified oversight and appropriate disclosure.

What Is Hailuo 2.3 Fast Best Used For?

The model is not universally "best." It may fit the following scenarios when its image-input requirement and short duration align with the production brief.

How Does Hailuo 2.3 Fast Compare to Hailuo 2.3 and Hailuo 02?

The comparison does not identify an overall winner. Hailuo 2.3 Fast is the narrower, lower-priced option when a starting image is already available. Standard Hailuo 2.3 is more relevant when text-only generation is required. Hailuo 02 may remain useful for existing integrations or 512p output. Model-specific output quality should be tested on the intended content rather than inferred from pricing alone.

How Do I Access Hailuo 2.3 Fast Through Gate.AI?

As per the Gate.AI listing, the Gate.AI model ID is:

BAAI/hailuo-2.3-fast

Gate.AI provides a dedicated asynchronous video-generation API. Its documentation identifies the video endpoint as:

POST https://api.gate.ai/api/v1/videos

Authentication uses a Gate.AI API key as a bearer token. Gate.AI API keys are created from the console under Settings and API Keys. The broader Gate.AI platform also documents unified model access and model selection through provider/model identifiers.

Python Example

import os
from typing import Any
import requests
API_URL = "https://api.gate.ai/api/v1/videos"
API_KEY = os.environ["GATEAI_API_KEY"]
payload: dict[str, Any] = {
    "model": "BAAI/hailuo-2.3-fast",
    "prompt": (
        "[Push in] The subject turns slightly toward the camera "
        "while the background foliage moves gently."
    ),
    "duration": 6,
    "resolution": "768p",
    "input_references": [
        {
            "type": "image",
            "url": "https://example.com/source-image.jpg",
            "role": "first_frame",
        }
    ],
}
response = requests.post(
    API_URL,
    headers={
        "Authorization": f"Bearer {API_KEY}",
        "Content-Type": "application/json",
    },
    json=payload,
    timeout=30,
)
response.raise_for_status()
job = response.json()
print(job)

curl Example

curl "https://api.gate.ai/api/v1/videos" \
  -H "Authorization: Bearer $GATEAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "BAAI/hailuo-2.3-fast",
    "prompt": "[Tracking shot] The subject walks forward while leaves move gently.",
    "duration": 6,
    "resolution": "768p",
    "input_references": [
      {
        "type": "image",
        "url": "https://example.com/source-image.jpg",
        "role": "first_frame"
      }
    ]
  }'

The request creates an asynchronous generation job rather than returning the completed video immediately. Applications should store the returned job identifier or status URL, check progress according to the documented workflow, and retrieve the completed media from the returned download information.

Production implementations should validate image URLs, protect API keys with environment variables or a secrets manager, apply request timeouts, and handle authentication failures, insufficient balance, invalid inputs, rate limits, upstream failures, and unsuccessful generation jobs.

FAQs

Does Hailuo 2.3 Fast have a 131K context window?

No. Hailuo 2.3 Fast is a video-generation model rather than a token-based language model, so a 131K context window is not an applicable specification. MiniMax’s documented image-to-video API instead permits an optional text prompt of up to 2,000 characters.

How much does Hailuo 2.3 Fast cost?

As of July 2026, MiniMax lists Hailuo 2.3 Fast at \$0.19 for a six-second 768p video, \$0.32 for a ten-second 768p video, and \$0.33 for a six-second 1080p video. Billing is per generated video, not per token.

Can Hailuo 2.3 Fast generate a video from text alone?

Not in its officially documented Fast configuration. MiniMax classifies Hailuo 2.3 Fast as an image-to-video model. It requires a source image and can use an optional text prompt to guide motion, style, action, and camera movement.

When should I choose Hailuo 2.3 Fast instead of Hailuo 2.3?

Hailuo 2.3 Fast may fit when a starting image is available and lower generation cost is a priority. Standard Hailuo 2.3 is more relevant when the workflow also requires text-to-video input. Output quality should be tested with representative assets before selection.
