Frequently asked questions
Which AI model has the largest context window?
GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.6 Luna, GPT-5.5 lead with a 1,050,000-token (1.1M) context window — enough to hold large codebases or several long documents at once.
Which AI model API is cheapest?
On input tokens, GPT-5.6 Luna, GPT-5.4 nano, Llama 4 Maverick (hosted) is the cheapest at $0.20 per 1M tokens. Total cost depends on output length too — output usually costs several times more than input.
Which AI models are open-weight?
DeepSeek V4, DeepSeek V3.2, Llama 4 Maverick (hosted), Mistral Large 3 are open-weight, meaning you can self-host them. The rest (OpenAI, Anthropic, Google, xAI) are API-only.
Which AI model has real-time web access?
GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.6 Luna, Grok 4.3 has native live web/search access, making it the strongest pick for current events and time-sensitive research. Others rely on their training data unless you add a search tool.
How current is this pricing and these specs?
These figures were web-verified against each provider's documentation in August 2026. LLM pricing and model lineups change often, so each model links to its provider source — confirm before budgeting.
