Gemini Robotics ER 2 Streaming Preview

Google's gemini-robotics-er-2-streaming-preview, 131K tokens of context. Every number on this page was read off Google's own pricing page — never estimated, never recalled from memory.

Promotional pricing until December 31, 2026. After that date it reverts to list price: $2.00 input and $10.00 output per 1M tokens — roughly 2.0× the current input price. Budget for the change now, not in December.

How Google describes it

“Gemini Robotics ER 2 Streaming is a vision-language model endpoint for robotics optimized for real-time text streaming using the Live API.”

Pricing

At the calculator's starting volume, 1M input tokens and 200K output tokens with no cache hits, Gemini Robotics ER 2 Streaming Preview costs $2.00: $1.00 for input and $1.00 for output, at the promotional prices above. Same formula as the calculator; change the volume there.

Where this price sits

$1.00 per 1M input tokens is the 22nd cheapest input price of the 67 current models with a verified price on this site, and the 7th of Google's 11. Output costs 5.0× the input price.

• September 16, 2026 · added to this dataset, our omission

  Omission on our side, not a price change by any provider. On September 16, 2026, while reading OpenAI's pricing page by hand for a check on batch and flex prices, GPT-6 Astra turned up in the Standard table with no row in this dataset. A hand sweep of the first-party pricing pages of OpenAI, Anthropic, Google, xAI, Mistral, DeepSeek, Alibaba and Cohere against the dataset then found eight models charged per token with text output and a published price that had no row: GPT-6 Astra and GPT-Rosalind (OpenAI), Claude Haiku 3.5 (Anthropic, retired on the first-party API but still priced), Gemini 2.5 Computer Use Preview, Gemini Robotics ER 2 Preview and its Streaming variant, and Gemini Omni Flash Preview, a separate endpoint id from the generally available Omni Flash row at the same prices (Google), and GLM 5.3 (served by Mistral). Astra had been in OpenAI's Standard table at least since September 10, 2026, when the weekly detector first received that page's text, and this site's OpenRouter explainer already named it from the September 15 snapshot. The weekly detector could not have caught any of these: it compares the rows that exist against the page and has no step for models the page lists and the dataset does not. Each new row carries the page quote it was read from. Audio, image, video, embedding and per-minute models found in the same sweep were left out on purpose: the table covers models charged per token with text output.

Added 2026-09-16 after a hand sweep of Google's pricing page found it missing from this dataset (our omission). Page block 'Gemini Robotics ER 2 Streaming Preview gemini-robotics-er-2-streaming-preview … a vision-language model endpoint for robotics optimized for real-time text streaming using the Live API'. Paid Tier: 'Input price … $1.00 (text / image / video / audio) through December 31, 2026. $2.00 (text / image / video / audio) starting January 1, 2027. Output price … $5.00 through December 31, 2026. $10.00 starting January 1, 2027.' No context caching price and no context window on the page.
