## What it does

The skill walks the agent through a short workflow: build a shortlist from search or collections, fetch each model's schema, then compare inputs, outputs and supported features. Pricing comes from model metadata or the Replicate site, and quality gets checked by running the same prompts through every candidate.

Speed is read from `metrics.predict_time` on completed predictions. Official models are always warm; community models can cold-boot. Billing differs too — official models have predictable per-run pricing, while community models charge by GPU time. So after a few test runs, check the `metrics` field for the actual cost.

The skill also lays out the tradeoffs. Smaller distilled models are cheapest, at the cost of slower inference and lower quality. Official or schnell/turbo variants cut latency but raise the price per run. Models with ControlNet, masks or reference images give the most control, and the input setup gets more involved. For prompting technique it points to the neighbouring `prompt-images` and `prompt-videos` skills. If a community model fits and no official one does, the guidance suggests creating a deployment for consistent uptime.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add replicate/skills --skill compare-models -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/compare-models/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/compare-models/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add replicate/skills --skill compare-models -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/compare-models/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add replicate/skills --skill compare-models -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/compare-models/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install replicate/skills compare-models
```

2. **Manually: put the files in place**
- File: `.github/skills/compare-models/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add replicate/skills --skill compare-models -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/replicate/skills --path skills/compare-models
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/compare-models/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add replicate/skills --skill compare-models -a opencode
```

## When to use it
- shortlist Replicate models that fit a task
- compare per-run cost of an official model against a community one
- measure real inference time from `metrics.predict_time`
- run identical prompts across models and compare the output
- find a model with the inputs you need: masks, references, aspect ratios

## Example prompts
- compare Replicate image models by cost and speed
- run the same prompt through three models and show the quality difference
- which community models can replace the official one, and what will a run cost

## Workflow

1. Search or browse collections to build a shortlist of candidate models.
2. Fetch each model's schema to compare inputs, outputs, and capabilities.
3. Check pricing from model metadata or the Replicate website.
4. Run a small batch of test predictions to compare output quality.
5. Pick the model that best fits your constraints (cost, latency, quality).

## What to compare

- **Speed**: Check `metrics.predict_time` on completed predictions for actual inference time. Official models are always warm. Community models can cold-boot.
- **Cost**: Official models have predictable per-run pricing. Community models charge by compute time (GPU-seconds). Run a few predictions and check the `metrics` field for actual cost.
- **Quality**: Run the same prompts through each model and compare outputs. Quality is subjective. Match it to your use case, not a leaderboard.
- **Capabilities**: Compare input schemas for supported features (reference images, masks, aspect ratios, streaming, multi-image input). Check output formats.

## Key tradeoffs

- Lowest cost: smaller/distilled models. Accept slower inference and lower quality.
- Lowest latency: official models or schnell/turbo variants. Accept higher cost per run.
- Highest quality: pro/max/quality variants. Accept slower inference and higher cost.
- Most control: models with ControlNet, masks, or reference images. Accept more complex input setup.

## Official vs community models

- Official models: always warm, stable APIs, predictable pricing, maintained by Replicate.
- Community models: may cold-boot, require version pinning, maintained by the author.
- If a community model meets your needs and an official model doesn't, consider creating a deployment for consistent uptime.

## Prompting guidance

For prompting techniques and task-specific guidance:

- Image generation and editing: see the [prompt-images](../prompt-images/SKILL.md) skill.
- Video generation: see the [prompt-videos](../prompt-videos/SKILL.md) skill.
