MiniMax M3.1 Flash launches with speed, cost gains, but high hallucination rate

By PulseAugur Editorial · [1 sources] ·

MiniMax has launched its M3.1 Flash model, boasting significant speed and cost improvements over previous generations and competitors like DeepSeek. The model offers a 1 million token context window and supports multimodal inputs, with pricing set at $0.15/$0.60 per 1M tokens for input/output. However, early reports indicate a high hallucination rate, with the model frequently guessing when uncertain rather than stating it doesn't know. AI

IMPACT This release sets a new benchmark for agentic task costs and inference speed, potentially pressuring competitors to match its performance and pricing.

RANK_REASON New model release from a frontier lab (MiniMax). [lever_c_demoted from frontier_release: ic=1 ai=1.0]
