What Startups Actually Need
Startups don't need the fanciest model — they need to ship features fast, keep the bill tiny, and stay flexible as models change monthly. That points to a specific setup: one integration across many models, a free way to start, predictable pricing, and easy routing so you can use a cheap model for the bulk and a premium one only where it counts. Here's the playbook.
One Key, Every Modality
Most AI-powered products touch more than one model type — chat, plus image or video generation. Integrating each provider separately burns your scarcest resource: engineering time. A single gateway like LinkModel gives you one key and one request shape across:
- Chat — Claude, GPT, Gemini, DeepSeek
- Image — GPT Image 2, Nano Banana, Seedream
- Video — Seedance 2.0, Kling V3, Hailuo
Swap models with a config change instead of a new integration — the pattern in build an AI app with multiple models.
Start Free, Scale Predictably
- Free to start: a $1 signup credit covers real generations across models — validate before you spend. See free AI image generation API.
- Fixed per-request pricing: the price shows before each call, so you can forecast burn — critical when runway is finite.
- Up to 30% below official rates, with no minimums.
The Startup Cost Playbook
- Cheap default, premium escalation. Run the bulk on DeepSeek V4 Flash ($0.14/$0.28) or Gemini Flash-Lite; reserve Claude/GPT for the hard 5%. A 5–25x lever.
- Cache the stable context (system prompt, docs) — up to 90–98% off repeated input.
- Batch non-urgent jobs — 50% off.
- Right-size image/video resolution — don't ship 4K where 1080p works.

Ship Your First Feature
curl -X POST https://api.linkmodel.ai/api/v1/image-generation \
-H "Authorization: Bearer $LINKMODEL_API_KEY" -H "Content-Type: application/json" \
-d '{ "model": "seedream-5.0-lite", "prompt": "App onboarding illustration, friendly, flat style" }'The same key runs your chat and video features too.
Why Not Just Go Direct?
Direct provider APIs mean multiple keys, bills, SDKs, and rate limits to manage — and rebuilding when you switch models. For a small team, a gateway trades a tiny margin for large savings in engineering time and flexibility. Weigh it in OpenRouter alternatives and serverless GPU vs generation API.
Bottom Line
For startups: one key across modalities, start on the free credit, default to cheap models, escalate only when needed. You ship faster, forecast cleaner, and stay free to swap models as the field moves.
