Models

Model Milestones

• Intern-S1: Our latest open-source multimodal large model enhanced with advanced scientific reasoning capabilities. It currently delivers the best overall performance among all open-source multimodal models.
• InternLM3: Our latest series of large language models with exceptional reasoning capabilities, leading the open-source models in this class.
• InternVL2.5: Our multimodal large model series, the first open-source model to match the performance of top proprietary models like GPT-4 and Gemini Pro.

Using the Latest Model

For multi-turn conversation APIs, use the following in the model field:

• intern-latest automatically refers to our most recent model release, which currently points to intern-s1.
• internlm3-latest will automatically point to the latest version in the large language model series.

You can check the specific model version they point to by checking the ref_model field in the response from the models API (e.g., internlm3-8b-instruct).
