You don't need a credit card to start building with AI. We ranked the best free LLM APIs by quality, limits, and developer experience so you can ship your prototype today. Access all of them through LLMWise.
Free preview, Starter for the Auto lane, Teams for manual GPT, Claude, and Gemini Pro access. Add-on credits kick in after included plan tokens are used.
Start on cheap auto-routed models first, then move up only when your workload truly needs premium manual control.
The most generous free gateway to multiple open-source models. OpenRouter Free gives developers access to a rotating selection of open-weight models with no API key charges, making it the easiest way to prototype against real LLM endpoints without spending a cent.
A purpose-built free model that punches well above its weight class. Arcee Trinity is optimized for instruction following and coding tasks, delivering surprisingly strong results for a completely free offering with no hidden usage caps.
A novel architecture that offers free chain-of-thought reasoning. LFM 2.5 Thinking provides access to Liquid AI's efficient transformer alternative with built-in reasoning capabilities, giving developers a free path to test agentic and multi-step workflows.
Google's free tier is the most feature-complete among major providers. Gemini 3 Flash offers generous daily request limits, multimodal input support, and a massive context window in its free tier, making it the best free option for production-quality prototyping.
Not technically free, but so cheap it might as well be. DeepSeek V3 offers frontier-level reasoning and coding at the lowest per-token price of any major model, making it the best upgrade path when free tiers run out.
Ranking evidence from practical criteria teams use for real production traffic.
Start with OpenRouter Free or Gemini 3 Flash's free tier for initial prototyping, then evaluate Arcee Trinity and LFM 2.5 Thinking for specialized use cases. When you're ready to scale past free limits, DeepSeek V3 offers the gentlest cost curve. LLMWise lets you switch between all of these without changing your integration.
