## Which one, for what

### Iris-3B (D)

Good for: An agent on a machine with a CUDA GPU that needs Apache-2.0 image generation, relative depth or 4x restoration without a vendor account.

Ahead on:
- Security & auth, 44 against 30
- Payments & pricing, 60 against 30
- Maintenance & community, 70 against 48

Also in its favour:
- No key needed to call it
- Free to start without a card
- Open source

Watch for: No package on PyPI, no version tags, no changelog and no CI workflow. Install is a git clone and `pip install -e .`

### Recraft API (D)

Good for: Logos, icons and brand-consistent graphics where SVG matters.

Ahead on:
- Reliability, 70 against 45
- Schema & documentation, 64 against 47
- Agent ergonomics, 62 against 54
- Transparency & trust, 59 against 47

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No changelog and no error reference

## Verdicts

**Iris-3B.** Code and weights are Apache-2.0, and one Python package runs text-to-image, a 4-step Turbo, depth and 4x restoration from a documented CLI. It is ten days old, with no PyPI package, version tags, changelog or CI, needs an NVIDIA GPU and about 12 GB of weights, and has no server or API of its own.

**Recraft API.** Native SVG vector generation, not traced raster. No changelog and no error reference.

## Before you call either

### Iris-3B

1. Check for an NVIDIA GPU with CUDA and Python 3.11 or newer before downloading. The base weights are about 12 GB, and Qwen3-VL-4B downloads on the first run
2. Exclude `depth/*`, `upscaler/*` and `turbo/*` in `hf download` unless those models are needed. Each of the first two adds about 12 GB
3. Don't pass `--steps`, `--cfg-scale`, `--negative-prompt`, `--order` or `--shift` with a Turbo checkpoint. The script exits with an error
4. Pass `--seed` to reproduce an image, and set `--outdir`, since files are named after the prompt and a repeat run overwrites them
5. Load only exported directories (`model.safetensors` and `config.yaml`). A training `.pth` is read with `torch.load(weights_only=False)`, so never load one from an untrusted source

### Recraft API

1. Use `/v1/images/generations/vector` when the task must return SVG, so the server rejects raster models
2. Ask for `b64_json` or `multipart` if you can't fetch the URL within a day
3. Name `recraftv4_1_flash` for drafts at $0.007. The default `recraftv4_1` costs $0.035
4. Stay under 100 images a minute and 5 requests a second per user
5. Point the OpenAI SDK at `https://external.api.recraft.ai/v1`, but expect some parameters to be ignored
