OpenAI charge considerably more for GPT4 and other premium AI models. Unfortunately we rely on support to enable these models. Currently a subscription will unlock the GPT 3.5 16k context model, but if there is more support GPT 4 will be added.
A LegacyAI subscription costs $2/month and you must have an existing license. Please be patient while we grant you access, this may take up to 24hrs to take effect.
