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.\n\n**Seedream on BytePlus ModelArk.** Per-image prices from $0.018 are public, and API keys can be limited to named models and an IP allowlist. No status page, SLA or OpenAPI file was found, onboarding needs a browser sign-up, and BytePlus says its model services are not available in the United States.\n\n## Before you call either\n\n### Iris-3B\n\n1. 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\n2. Exclude `depth/*`, `upscaler/*` and `turbo/*` in `hf download` unless those models are needed. Each of the first two adds about 12 GB\n3. Don't pass `--steps`, `--cfg-scale`, `--negative-prompt`, `--order` or `--shift` with a Turbo checkpoint. The script exits with an error\n4. Pass `--seed` to reproduce an image, and set `--outdir`, since files are named after the prompt and a repeat run overwrites them\n5. 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\n\n### Seedream on BytePlus ModelArk\n\n1. POST to `https://ark.ap-southeast.bytepluses.com/api/v3/images/generations` with `Authorization: Bearer $ARK_API_KEY`. Keys and model activation are per region\n2. Set `watermark` to false if the image must not carry the AI-generated mark. The default is true\n3. Download `data[].url` within 24 hours, or ask for `response_format` `b64_json`\n4. Check each `data[].error` in a sequential batch. One moderated image does not fail the others, and only `usage.generated_images` is billed\n5. Stay under 500 images a minute per model and back off with jitter on 429. Layer decomposition reserves 17 against that limit per request\n\n## Questions\n\n### Which is better for AI agents, Iris-3B or Seedream on BytePlus ModelArk?\n\nSeedream on BytePlus ModelArk scores 53.8 (D) on agent readiness against Iris-3B's 50.9 (D), and leads in 5 of 7 scored categories. Iris-3B leads on payments \u0026 pricing.\n\n### Do Iris-3B and Seedream on BytePlus ModelArk need an API key?\n\nIris-3B needs no key. Seedream on BytePlus ModelArk needs an API key.\n\n### Can an agent call Iris-3B and Seedream on BytePlus ModelArk without installing anything?\n\nNo hosted endpoint is listed for Iris-3B. Seedream on BytePlus ModelArk has a hosted endpoint at https://ark.ap-southeast.bytepluses.com/api/v3.\n\n### Are Iris-3B and Seedream on BytePlus ModelArk open source?\n\nIris-3B is open source (Apache-2.0 (code and weights)). No open-source release is listed for Seedream on BytePlus ModelArk.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/iris-3b-vs-seedream-on-byteplus-modelark.json, and with the fewest tokens: https://www.anchorterminal.com/compare/iris-3b-vs-seedream-on-byteplus-modelark.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"iris-3b\", \"b\": \"seedream-on-byteplus-modelark\"}`.
