Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
AI article rewriter that produces unique, human-quality text
A large-language-model engine that determines the meaning of each word in context, producing readable rewrites instead of awkward synonym substitution.
Generate up to 1,000 unique versions of one source article in a single pass, enough to populate many sites from one piece of content.
Supports all five popular spintax formats and can rewrite multiple articles in bulk, fitting existing publishing pipelines.
Virtually every major SEO tool integrates Spin Rewriter through its API, so rewrites can run from inside your preferred software.
