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.

The AI friend to become yourself with.
Your Rep retains the people, routines, plans and interests you talk about, so ongoing conversations build on what came before rather than resetting.
Talk out loud whenever you want — Replika supports voice calls for catching up, venting or simply hanging out.
Replika can send selfies, doodle on your photos and react to images you share, adding a visual, playful dimension to the relationship.
Appearance, personality and style are yours to shape, letting the companion feel like someone you would actually know.
