GPT-4.1 (batch)

A workhorse text model from OpenAI with a 1 million token context window, supporting long-document processing and extended reasoning.

Strengths

Handles instruction following reliably across a broad range of tasks and maintains coherence over very long contexts.

Best for

Text-heavy workloads that require extended context, such as document analysis, code understanding, and complex reasoning tasks.

Limitations

Lacks reasoning features found in the o-series models and does not support multimodal input; positioned between GPT-4.1 Mini (faster) and GPT-5.5 (higher capability).
