- ChatGPT (OpenAI) — best overall, personal AI assistant
- Gemini / Bard (Google) — image gen, web productivity (budget)
- Perplexity — research + sources
- Claude (Anthropic) — content creation, writing, coding
- DeepSeek (Chinese) — best open-source
- Meta AI (Meta) — ???
- Grok (xAI) — ???
- Copilot (Microsoft) — microsoft users
- LLMs: Large Language Models — broad AI models trained on massive datasets to understand and generate human language (basically NLP models on steroids)
- GPT-4, Llama, Claude, Mistral, etc.
- → they are general-purpose engines that can perform many language-related tasks beyond chatting, such as translation, code gen, content creation etc.
- Chatbot: specialised AI apps built on or powered by LLMs (or other models), designed for conversation and dialogue ⇒ conversational agents
- → they remember previous interactions, keep context, deliver more coherent and context-aware responses.
- → the traditional chatbots (that are not LLM-powered) often rely on rule-based or template-driven responses and lack flexibility and contextual understanding
Claude
Are there any usage limits or limits on chat length?
While using the free Claude plan, there is a session-based usage limit that will reset every five hours. Also, the number of messages you can send will vary based on demand, and we may impose other types of usage limits to ensure fair access to all users. Claude will notify you when you’ve reached your limit, or if your prompt exceeds the available context window.
- “~40 messages/day (resets daily)”
- then you’re blocked.
Gemini
- “20 requests per day”
- ⇒ in reality this seems like more… haven’t hit a limit yet
Chatgpt
- there is a limit to use the pro version
- but the free version is always available
