GPT-4 (June 2023) is the June 2023 snapshot of the original GPT-4 model, predating the Turbo line. OpenAI offers this pinned version primarily for legacy compatibility — teams that built and tuned prompts against the June 2023 behavior can continue using it without worrying about model drift or changed capabilities.
Relative to later GPT-4 variants, this snapshot has a shorter context window and no native vision support, but its text reasoning quality remains solid. It is the right choice when stability and backward compatibility outweigh the need for the latest improvements, particularly for applications in production since mid-2023 that have been validated against this specific checkpoint.
