Last month: https://manifold.markets/prismatic/march-2026-ai-model-releases
This market resolves YES for each AI model that receives an official public release during April 2026. A release counts as available to users if it is made available through official channels (API, web interface, download, or official partnership).
Subvariants are model releases that share the same tier name (e.g., Flash Preview, Flash Live, Flash Instant all count for "Gemini 3.1 Flash"; 5.5-Thinking, 5.5-Instant, 5.5-Nano, 5.5-Pro all count for "GPT5.5"). Releases with a distinct tier name (Flash-Lite, Flash, Pro as a separate tier, etc.) do NOT count for an adjacent tier, even within the same model family. When in doubt, I'll use the official model name the company uses to classify it.
Please ask for clarifications. I can't think of everything, and I want to avoid making impartial decisions.
Also, if you would like any model to be added, ping me.
Update 2026-03-26 (PST) (AI summary of creator comment): For DeepSeek V4, both V4-Lite and V4 Full (and any other V4 variants) count toward resolution.
Update 2026-03-26 (PST) (AI summary of creator comment): Haiku 4.6 has been added as a tracked model for this market.
