LiquidAI: LFM2.5-1.2B-Instruct (free)Model24/100 via “free api access with usage-based rate limiting”
LFM2.5-1.2B-Instruct is a compact, high-performance instruction-tuned model built for fast on-device AI. It delivers strong chat quality in a 1.2B parameter footprint, with efficient edge inference and broad runtime support.
Unique: Offers completely free API access through OpenRouter's aggregation platform, eliminating cost barriers for prototyping while maintaining fair-use rate limiting — enables cost-free evaluation without requiring local infrastructure
vs others: Free access removes cost barriers compared to paid APIs (OpenAI, Anthropic), but rate limiting and potential deprioritization make it unsuitable for production workloads; simpler than self-hosting but requires internet connectivity
