## Agent Opus

Agent Opus lives at opus.pro/agent and is built by OpusClip Inc., the team behind the well-known OpusClip repurposing tool. Instead of chopping up existing footage, Agent Opus works in the opposite direction: you start with an idea, a script, or an audio file, and the agent assembles a complete story video — narration, visuals, captions, and brand styling — ready to publish.

The product is aimed at creators and brands who post consistently across short-form platforms. It ships with a library of proven viral formats (AI ads, explainer videos, personal narratives, audio-to-video, B-roll enhancement) that you can remix, so you are not starting from a blank canvas. Feed in your brand assets, tone, and voice once, and every generated video is supposed to look and sound like your channel.

Pricing is credit-based. You can start with 90 free credits without a credit card, and OpusClip offers paid plans plus a Discord community, prompt guide, and partner program. Because it is delivered as a web app, there is nothing to install — you paste a script or upload audio and generate in the browser.

**Pricing & Plans:** Freemium. New users get 90 free credits with no credit card required; paid OpusClip plans and a partner program are available. Check opus.pro for current tiers.

- **Idea, script, or audio input:** Start from a text prompt, a full script, or an uploaded audio recording and let the agent generate the complete video.
- **Viral format library:** Remix proven templates such as AI ads, explainers, B-roll enhancement, personal narratives, and audio-to-video.
- **Brand-aware generation:** Configure your brand assets, voice, and style once so every video matches your channel's look automatically.
- **One-click publish readiness:** Generated videos come out formatted and captioned for social platforms, so the workflow is create-then-post.
- **Ads and campaign variants:** Upload brand assets and generate new ad variants on demand to test more creative without more production cost.

**Strengths:** No timeline editing — the agent handles assembly and formatting; Accepts scripts, rough ideas, or raw audio as a starting point; Brand assets carry through to every generated video; Free credits let you test the workflow before paying

**Limitations:** Credit-based pricing means heavy usage scales the cost up; Output quality depends on how good your source script or audio is; Templates are tuned for social/short-form rather than long-form cinema

## BigModel

BigModel is Zhipu AI's developer-facing platform, offering API access to the company's GLM series of large language models and a broad set of multimodal capabilities. Instead of juggling separate vendors, teams can call text generation, vision-language understanding, OCR, speech recognition, speech synthesis, image generation, and video generation endpoints from one account and one set of credentials.

Beyond raw model access, the platform targets application builders. It includes an agent framework, MCP service support, knowledge-base tooling for retrieval-augmented generation, model fine-tuning workflows, and a model playground for quick testing in the browser. There are also adjacent offerings such as an AI coding assistant and visual/low-code building experiences aimed at teams that want to ship without heavy ML engineering.

For organizations with stricter requirements, BigModel supports private instance deployment and on-premise options, alongside token-based pay-as-you-go and enterprise contracts. This makes it a fit for both individual developers prototyping on a budget and enterprises that need data to stay inside their own infrastructure.

**Pricing & Plans:** BigModel follows a freemium, token-based model: new users typically receive free trial credits, then pay-as-you-go for API usage by tokens consumed. Larger volumes, private instance deployment, and on-premise installations are arranged through contact-for-pricing enterprise agreements. Always confirm current rates on the official pricing page.

- **GLM text and multimodal APIs:** Unified access to GLM large language models plus vision, OCR, speech, image, and video endpoints through one account.
- **Agent and MCP support:** Build tool-using agents and expose or consume MCP services to connect models to external systems.
- **Knowledge base and RAG tooling:** Create managed knowledge bases and retrieval pipelines so models can answer with your own documents.
- **Fine-tuning and playground:** Tune models on your data and prototype prompts interactively in the browser before shipping.
- **Private and on-premise deployment:** Run models in a private instance or on your own hardware for data-residency and compliance needs.

**Strengths:** Broad model coverage, from LLMs to vision, speech, and video, under one platform; Officially backs the GLM family, so model documentation and updates are first-party; Supports private and on-premise deployment for strict data requirements; Includes agent, knowledge-base, and fine-tuning tooling beyond raw API access

**Limitations:** Pricing and documentation are primarily Chinese-first, which can slow English-only teams; Some enterprise capabilities require sales contact rather than transparent self-serve pricing; Token costs can grow quickly for high-volume multimodal workloads
