InternLM3 8B-Instruct

InternLM3 8B-Instruct is an 8B model for general tasks and advanced reasoning. Its most useful interaction idea is switching between a normal response and a deep-thinking mode within the same checkpoint. That mode switch saves latency on simple requests and allows more deliberate work on harder ones without changing model IDs. The card also describes pretraining on 4 trillion high-quality tokens.

The checkpoint has a 32,768-token context and uses Apache 2.0. InternLM’s lower training-cost figure describes model development, not an independent runtime result.
