Meta has released its own AI service, based on the Llama 3 model, offering free "text-to-text" and "text-to-image" functions with impressive results. This could be OpenAI's strongest competitor to date.
Meta also has a dedicated Llama chat website llama.dev, where you can choose different versions of the model.
A free AI chat service launched by the search engine DuckDuckGo, using GPT-3.5 Turbo and Claude 1.2 models as its underlying technology.
Groq has opened up free API access to large language models, allowing users to use Meta's Llama-3-8b-4096, Llama-3-70b-8192, and Mistral's mixtral-8x22-327b8 models without charge. You can use it immediately after registration, with no application required.
Le Chat Mistral is an AI conversation tool launched by Mistral AI, similar to OpenAI's ChatGPT, but with a lower barrier to entry.
