Particle AI: Particle-1
Particle-1 is a model from Particle AI that accepts text and image inputs and returns text. It offers a context window of 1,048,576 tokens, roughly one million, and can generate up to 131,072 tokens in a single completion. It supports tool calling and reasoning, which makes it usable in agent-style workflows. Its support for structured output and the availability of open weights are not specified, so check vendor documentation if either matters to your deployment. The clearest reason to shortlist this model is cost. Input is priced at $0.05 per million tokens and output at $0.50 per million, which suits high-volume workloads such as processing long documents or large batches of images alongside text. Its quality is unproven, however. It has no independent benchmark coverage yet, so run your own evaluations against comparable models before relying on it for accuracy-sensitive tasks.
