If you are building Agents, designing workflows, or producing short videos and need to call text, image, and video models at the same time, Agnes AI has just offered a proposition that is hard to refuse: the APIs of its three core models are free indefinitely.

This means you no longer need to budget carefully for token consumption, nor bounce back and forth between multiple platforms. One API system covers three capabilities: text generation, image editing, and video generation.

What Is Agnes AI

Agnes AI is a lab ranked 9th among global AI Labs, consistently listed on international evaluation systems such as PinchBench, Claw-Eval, and Artificial Analysis. Its core product line includes three models:

• Agnes-2.0-Flash: A text model supporting a 1M context window and tool calls
• Agnes-Image-2.0-Flash: An image model supporting image-to-image editing, multi-image fusion, local editing, and text modification
• Agnes-Video-V2.0: A video model supporting synchronized audio-video generation and first-frame / first-and-last-frame video generation

Starting June 1, 2026, the APIs of the three models above are open to developers worldwide, free of charge and indefinitely.

The three models cover the three major modalities of text, image, and video under a unified API system

The Text Model: Code Generation with a 1M Context

Agnes-2.0-Flash supports scenarios such as code development, enterprise knowledge bases, intelligent customer service, document processing, and Agent workflows. In hands-on testing, it pulled off several impressive tasks:

Scenario 1: Web game generation. A single prompt generates a complete airplane shooter game, including fighter jets, minions, boss battles, a scoring system, health points, combo notifications, particle explosions, and a dynamic starfield background.

Scenario 2: Product prototype building. With just one sentence of prompting, it generates an MBTI personality test website, complete with a full test flow, result calculation logic, and personality type display pages.

Scenario 3: Frontend UI generation. After describing requirements with a complex prompt, the model integrates product requirements, UI structure, interaction logic, and visual style into a single runnable HTML file.

# Example prompt: generate a maps app
Help me build an Amap-style maps app, starting from Dongcheng District, Beijing.
The map must support zooming in and out, with input for destination and starting point,
a mobile vertical-screen app interface, maps app UI design, clean interface, layered UI layout, rounded layout...

The Image Model: Editability Is the Core Selling Point

Agnes-Image-2.0-Flash's biggest strength is not generating images, but editing images. It supports image-to-image editing, multi-image fusion, background replacement, local editing, text modification, and style transfer.

Portrait retouching: Even while drastically restyling a person, facial consistency stays stable. Skin texture, lighting layers, and lens feel all approach commercial photography quality.

E-commerce posters: Upload one real product photo, and the model automatically generates a complete poster with product selling-point copy, visual decorative elements, and e-commerce-style layout.

Infographics: It can generate flowcharts and educational explainers on demand, and even architectural concept design infographics based on marine creature features, organizing the layout automatically.

The Video Model: Synchronized Audio and Video Generation

Agnes-Video-V2.0 supports synchronized audio-video generation, the key capability that sets it apart from most video models. Output resolution is selectable at 720P or 1080P.

Musical performance scenes: The drummer's playing motions in the frame stay in sync with the timing of the drumbeats, and in the band shots the movements of the three figures — lead vocalist, guitarist, and drummer — broadly match the corresponding sounds.

Cinematic scenes: Characters' lip movements correspond to their lines, facial expressions and emotional shifts adjust with the dialogue, and the overall footage approaches the look of a live-action shoot.

Performance scenes: Emotion is conveyed through gaze, breathing, and facial detail, delivering richly layered performances close to those in film and TV work.

How to Get Started

1. Visit the Agnes AI developer platform and register an account
2. Obtain an API Key (free, indefinite)
3. Call the corresponding model endpoint based on your needs:
   • Text generation: call Agnes-2.0-Flash
   • Image editing: call Agnes-Image-2.0-Flash
   • Video generation: call Agnes-Video-V2.0

The three models share a unified API style, support mixed calls within the same project, and let you build a complete multimodal workflow.

Who It's For

• Independent developers: Validate product prototypes at zero cost and quickly build apps with text, image, and video capabilities
• E-commerce operators: Use the image model to batch-process product photos and generate e-commerce posters
• Short video teams: Use the video model to quickly generate material and storyboard tests
• Agent developers: Call full-modality capabilities within one model system and build Agent workflows

Comparison With Similar Products

Agnes AI's free strategy is not because its capabilities are weak — it is betting on a trend: when API call costs drop to zero, developers' room for trial and error is hugely unlocked, and the application ecosystem accelerates. For budget-constrained small and mid-sized teams and independent developers, this bet is worth watching.
