These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.

The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.

Ember-1: common questions

How does Ember-1 rank among AI models?

Ember-1 has no public ModelCap Index position as of 2 October 2026: the snapshot lacks enough matched benchmark evidence, or the identity match is unresolved. Its catalogue facts (price, context, providers) are shown without a rank.

How much does Ember-1 cost per 1M tokens?

Ember-1 is listed at $3.00 per 1M input tokens and $15.00 per 1M output tokens as of 2 October 2026. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $13.50 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.

What is the context window of Ember-1?

Ember-1 has a published context window of 1M tokens (1,048,576) and a maximum output of 944K tokens. Individual providers can serve less than the published maximum; the providers table lists each endpoint's own limit.

Is Ember-1 open-weight?

API only. No downloadable model weights are linked in the current source data; access is through a hosted API or product.

Which API providers serve Ember-1?

One provider serves Ember-1 through OpenRouter as of 2 October 2026: Fireworks. Each provider's price, context limit, quantization and measured uptime are in the providers table above.

When was Ember-1 released?

Ember-1 first appeared in the catalogue on 24 Sept 2026. It is the current version in its family. Rank and price movements since then are recorded on the site's changes feed.
