Add an AI Feature Without Burning Cash

Every founder wants an AI feature until they see the invoice. The trick is to prototype free, pay for speed only when latency hurts, and reach for startup credits only when real users show up.

Prototype on GitHub Models

GitHub Models gives rate-limited access to 40+ frontier models — GPT-4o, GPT-5, DeepSeek-R1, Llama 3.3 — with nothing but a GitHub account. OpenRouter exposes 30+ models at 20 requests a minute free. Both are perfect for clicking through an idea before you commit to a provider.

Pay for speed, not for tokens

Groq's free tier is 14,400 requests a day at low latency — great for chat and classification. Cerebras throws in 1 million tokens a day at 2,100 tokens a second on Wafer-Scale hardware. Together AI gives $5 in free credits on signup, enough for several million tokens across 50+ open models. Cloudflare Workers AI runs 50+ models at the edge with 10,000 free neurons a day, no card needed.

When you're shipping to real users

Anthropic's Claude for Startups offers up to $25,000 in API credits, and OpenAI Startup Credits run $5,000 to $50,000+. Both are free to apply for and remove the ceiling once you have traffic. For voice, Deepgram's $200 free credits cover speech-to-text, and ElevenLabs gives 10,000 characters a month of text-to-speech free.
