Our verdict

AnyGPT lets you define a chatbot's personality, knowledge base and conversational style from scratch, then run that persona on your choice of model, including GPT-4o-mini, Claude-3.5-Sonnet and Llama-Dolphin-70B. Beyond picking a model, you can tune parameters like temperature, top P and max tokens to shape how responses come out. Building a well-tuned persona takes real trial and error, and response quality shifts depending on which underlying model you pick, so people willing to experiment get more out of it than those wanting a single, ready-made chatbot.
