How to Get Free OpenAI, Anthropic & Google AI Credits in 2026

API bills are the new cloud bills for AI startups. The good news: every major lab runs credit programs in 2026, and the discounts for smart usage are enormous.

Where credits come from: Microsoft for Startups includes Azure OpenAI credits; Google Cloud's startup program covers Gemini API usage generously; Anthropic partners with accelerators and cloud marketplaces for Claude credits; and both major clouds let you burn committed credits on model APIs through Bedrock and Vertex. Accelerators (YC, Techstars, and hundreds of regional programs) unlock the highest tiers of all of these.

Stretching tactics with bigger impact than any coupon: prompt caching (up to 90% savings on repeated context), batch APIs (50% off non-urgent work), routing simple tasks to small models, and aggressive output-length limits. Most teams overspend 3-5x before optimizing — start optimized.
