Questions
What is the best alternative to GPT-4?
GPT-3.5 Turbo 16k ranks first: same maker, 2 squares away (F1), 90% cheaper input, 2× the context. Input is $3.00 per 1M tokens against $30.00 for GPT-4. Ranking is by position on the atlas, not by quality.
What is the cheapest alternative to GPT-4?
GPT-3.5 Turbo at $0.50 per 1M input tokens, 98% less than GPT-4, among the 15 closest.
Is there an open-weight alternative to GPT-4?
None of the 15 closest is marked open-weight in our records.
Which alternative has a larger context window?
Claude Opus 4, Claude Opus 4.1, o1, Claude Sonnet 4 and 10 more hold more than GPT-4's 8K; the largest is Claude Opus 4 at 200K.
How are alternatives ranked?
By distance on the atlas grid from GPT-4's square H1: the same square first, then neighbouring squares. Within the same distance, cheaper models come before pricier ones, then the lowest input price wins. We hold no capability data, so we do not claim a model can do what GPT-4 does, only that it costs and holds about the same. No vendor pays for position.
