Particle-1 in plain words

Particle-1 is a text model from Particle AI. It takes text and images as input and returns text. Its context window is 1,048,576 tokens. It costs 0.062059 credits per 1M input tokens and 0.620589 credits per 1M output tokens.

It is good at reasoning through multi-step problems and calling tools. It reads images as well as text. A context window of 1,048,576 tokens holds about 4,200,000 characters of English text, at 4 characters a token.

For example, a question of 2,000 tokens (about 8,000 characters) with an answer of 1,000 tokens (about 4,000 characters) costs 0.000745 credits. The exact charge follows the usage the model reports for your request.
