Nano Banana 2.1 at $1.50 per 1M input tokens and $7.50 output. The other 5 in E2: GPT-5.2 Chat, Mixtral 8x22B Instruct, Command R+ (08-2024), GPT Audio and GPT-4o.
Which E2 model is cheapest for a request that fills its context window?
Nano Banana 2.1, at about $0.13 for a prompt that fills its 66K window plus its output. The dearest of the 6 is GPT-4o at $0.36. The cheapest list price is not always the cheapest full-window request, because windows differ within a square.
Are any E2 models open-weight?
None of the 6 is marked open-weight in our records.
What does grid reference E2 mean?
E is the price column ($1–3 per 1M input tokens) and 2 is the context row (32–128K). Models in the same square are like-for-like on price and context only; the grid says nothing about quality.
