How these alternatives were chosen
Tools FastGPT names as alternatives that this directory also publishes, followed by others in AI. The order is not a ranking, and "—" means we have not checked that field — not that the answer is no.
FastGPT also lists LlamaIndex, Hugging Face Transformers, OpenAI API, Anthropic Claude API as alternatives. Those are not in this directory yet, so there is nothing to compare — and nothing to link to.
