Inflection AI
2 models built
Inflection AI is a US company founded in 2022, best known for Pi, its personal-AI chatbot built around conversational tone rather than raw benchmark performance. Most of the founding team moved to Microsoft in 2024, and the company has since pivoted toward enterprise AI. On OpenKey, Inflection's lineup is small: two text-to-text models, Inflection 3 Pi and Inflection 3 Productivity, both released October 11, 2024. Both share the same context length (8,000 tokens) and the same pricing, so this isn't a lab you pick for variety — it's a lab you pick if the Pi conversational style specifically fits your use case.
Lineup
With only two models, the choice comes down to use case, not price — they're identical on cost: $2.50/1M input and $10.00/1M output tokens for both Inflection 3 Pi and Inflection 3 Productivity. Pi is tuned for personal, conversational interaction; Productivity is aimed at task-oriented work. Neither has a free tier, and both are capped at 8,000 tokens of context, which is small next to most current models — don't route long-document or large-context workloads here.

Questions
- What does Inflection AI pricing look like on OpenKey?
- Both models are priced the same: $2.50 per 1M input tokens and $10.00 per 1M output tokens from Inflection. On OpenKey that's provider price x 1.03, so $2.575/1M input and $10.30/1M output. There's no free tier and no price spread to optimize around — the two models cost identically.
- Which Inflection model should I use?
- Pick Inflection 3 Pi for conversational, personal-assistant-style interactions — it's the model behind Inflection's Pi product. Pick Inflection 3 Productivity for task-focused work. Cost is identical between them, so the decision is purely about which interaction style fits your app.
- Can I access Inflection models through a single API key?
- Yes — both Inflection 3 Pi and Inflection 3 Productivity are available through OpenKey's unified API alongside 329 other models from 52 labs, so you don't need a separate Inflection account or key to call them.
