Overview

Llama 4 Scout 17B is Meta's latest-generation small-footprint model with an exceptionally large 10M-token context window — meaning you can ingest entire codebases, multi-hour transcripts, or thousand-page documents in a single request. Running on Cloudflare's global edge network, it combines the efficiency of a 17B-parameter model (with 16 active experts via MoE) with a context size that exceeds most flagship models. On the free tier it shares the 10,000 Neurons/day pool and uses Cloudflare's native API. For developers evaluating long-context architectures or building retrieval-free RAG alternatives, this is one of the few free options that can genuinely test 10M-token prompts.
