# Ideogram Upgrade & Migration

## Current State

!`npm list 2>/dev/null | head -10`

## Overview

Guide for migrating between Ideogram API versions. The primary migration path is from the legacy `/generate` endpoint (JSON body, V_1/V_2 models) to the V3 endpoints (multipart form data, new parameters). This covers breaking changes in request format, model names, aspect ratio syntax, style types, and new capabilities.

## Breaking Changes: Legacy to V3

| Aspect | Legacy (`/generate`) | V3 (`/v1/ideogram-v3/generate`) |
|--------|---------------------|--------------------------------|
| Content-Type | `application/json` | `multipart/form-data` |
| Body format | `{ "image_request": { ... } }` | FormData fields |
| Models | `V_1`, `V_1_TURBO`, `V_2`, `V_2_TURBO`, `V_2A` | Implicit V3 (no model field) |
| Aspect ratio | `ASPECT_16_9` | `16x9` |
| Style types | `AUTO`, `GENERAL`, `REALISTIC`, `DESIGN`, `RENDER_3D`, `ANIME` | `AUTO`, `GENERAL`, `REALISTIC`, `DESIGN`, `FICTION` |
| Magic prompt | `magic_prompt_option` | `magic_prompt` |
| New in V3 | -- | `rendering_speed`, `style_preset`, `style_codes`, `character_reference_images` |
| Color palette | Preset name or hex array | Same, with weight support |

## Instructions

### Step 1: Audit Current API Usage

```bash
set -euo pipefail
# Find all Ideogram API calls in your codebase
grep -rn "api.ideogram.ai" --include="*.ts" --include="*.js" --include="*.py" .
grep -rn "ASPECT_" --include="*.ts" --include="*.js" .
grep -rn "image_request" --include="*.ts" --include="*.js" .
grep -rn "magic_prompt_option" --include="*.ts" --include="*.js" .
```

### Step 2: Create Adapter for Both Versions

```typescript
// src/ideogram/adapter.ts
interface GenerateOptions {
  prompt: string;
  style?: string;
  aspectRatio?: string;
  negativePrompt?: string;
  seed?: number;
  renderingSpeed?: string; // V3 only
  stylePreset?: string;    // V3 only
}

const API_KEY = process.env.IDEOGRAM_API_KEY!;
const USE_V3 = process.env.IDEOGRAM_API_VERSION === "v3";

async function generateImage(options: GenerateOptions) {
  return USE_V3 ? generateV3(options) : generateLegacy(options);
}

// Legacy endpoint -- JSON body
async function generateLegacy(options: GenerateOptions) {
  const response = await fetch("https://api.ideogram.ai/generate", {
    method: "POST",
    headers: { "Api-Key": API_KEY, "Content-Type": "application/json" },
    body: JSON.stringify({
      image_request: {
        prompt: options.prompt,
        model: "V_2",
        style_type: options.style ?? "AUTO",
        aspect_ratio: options.aspectRatio ?? "ASPECT_1_1",
        magic_prompt_option: "AUTO",
        negative_prompt: options.negativePrompt,
        seed: options.seed,
      },
    }),
  });
  if (!response.ok) throw new Error(`Legacy generate: ${response.status}`);
  return response.json();
}

// V3 endpoint -- multipart form data
async function generateV3(options: GenerateOptions) {
  const form = new FormData();
  form.append("prompt", options.prompt);
  form.append("style_type", mapStyleToV3(options.style ?? "AUTO"));
  form.append("aspect_ratio", mapAspectRatioToV3(options.aspectRatio ?? "ASPECT_1_1"));
  form.append("magic_prompt", "AUTO");
  form.append("rendering_speed", options.renderingSpeed ?? "DEFAULT");
  if (options.negativePrompt) form.append("negative_prompt", options.negativePrompt);
  if (options.seed) form.append("seed", String(options.seed));
  if (options.stylePreset) form.append("style_preset", options.stylePreset);

  const response = await fetch("https://api.ideogram.ai/v1/ideogram-v3/generate", {
    method: "POST",
    headers: { "Api-Key": API_KEY },
    body: form,
  });
  if (!response.ok) throw new Error(`V3 generate: ${response.status}`);
  return response.json();
}
```

### Step 3: Map Legacy Enums to V3

```typescript
function mapAspectRatioToV3(legacy: string): string {
  const map: Record<string, string> = {
    "ASPECT_1_1": "1x1",    "ASPECT_16_9": "16x9",  "ASPECT_9_16": "9x16",
    "ASPECT_3_2": "3x2",    "ASPECT_2_3": "2x3",    "ASPECT_4_3": "4x3",
    "ASPECT_3_4": "3x4",    "ASPECT_10_16": "10x16", "ASPECT_16_10": "16x10",
    "ASPECT_1_3": "1x3",    "ASPECT_3_1": "3x1",
  };
  return map[legacy] ?? legacy; // Pass through if already V3 format
}

function mapStyleToV3(legacy: string): string {
  const map: Record<string, string> = {
    "AUTO": "AUTO",
    "GENERAL": "GENERAL",
    "REALISTIC": "REALISTIC",
    "DESIGN": "DESIGN",
    "RENDER_3D": "GENERAL",  // No V3 equivalent -- use GENERAL
    "ANIME": "FICTION",      // V3 renamed to FICTION
  };
  return map[legacy] ?? "GENERAL";
}
```

### Step 4: Feature Flag Rollout

```typescript
// Gradual migration with feature flag
function shouldUseV3(userId?: string): boolean {
  // Phase 1: Internal testing
  if (process.env.IDEOGRAM_FORCE_V3 === "true") return true;

  // Phase 2: Percentage rollout
  if (userId) {
    const hash = Array.from(userId).reduce((h, c) => h * 31 + c.charCodeAt(0), 0);
    const percentage = parseInt(process.env.IDEOGRAM_V3_PERCENTAGE ?? "0");
    return (Math.abs(hash) % 100) < percentage;
  }

  return false;
}
```

### Step 5: Validate Migration

```typescript
// Run both endpoints and compare results
async function validateMigration(prompt: string) {
  const [legacy, v3] = await Promise.all([
    generateLegacy({ prompt, style: "REALISTIC", aspectRatio: "ASPECT_16_9" }),
    generateV3({ prompt, style: "REALISTIC", aspectRatio: "ASPECT_16_9" }),
  ]);

  console.log("Legacy:", { resolution: legacy.data[0].resolution, seed: legacy.data[0].seed });
  console.log("V3:", { resolution: v3.data[0].resolution, seed: v3.data[0].seed });
  console.log("Both returned images:", legacy.data.length > 0 && v3.data.length > 0);
}
```

## V3 Exclusive Features

After migration, you gain access to:

- **Rendering speed**: `FLASH`, `TURBO`, `DEFAULT`, `QUALITY`
- **50+ style presets**: `OIL_PAINTING`, `WATERCOLOR`, `POP_ART`, `JAPANDI_FUSION`, etc.
- **Style codes**: 8-char hex codes for precise style matching
- **Character reference images**: Consistent character faces across generations
- **Style reference images**: Upload style examples
- **Color palettes with weights**: Fine-grained color control

## Error Handling

| Issue | Cause | Solution |
|-------|-------|----------|
| `RENDER_3D` fails in V3 | Removed from V3 style types | Map to `GENERAL` |
| `ANIME` fails in V3 | Renamed to `FICTION` | Update enum mapping |
| JSON body rejected by V3 | V3 requires multipart form | Switch to FormData |
| `magic_prompt_option` ignored | V3 uses `magic_prompt` | Update field name |
| `model` field in V3 | V3 has no model field | Remove from V3 requests |

## Output

- Adapter supporting both legacy and V3 endpoints
- Enum mapping functions for breaking changes
- Feature flag for gradual rollout
- Validation script comparing both endpoints
