Prices across this family

Prices are per million text tokens, matched by currency, processing mode and input tier. Caching, tools, media and taxes may cost extra. These are not per-request or subscription totals. A listed price does not guarantee that a model is still available.

Prices observed 2026-10-31 · Matching input tier 1 versions /1 developers.Other matching versions: 4 versions have no price under these conditions. Quoted currency does not imply payment support. Check each model’s own input limit before choosing a long-input tier.

Family parameters & versions

0 versions have verified published parameter counts; 5 have no usable value yet. Parameter count is not a performance ranking.

Parameter counts for this group have not yet been verified, so no numeric bars are shown. Check the uses, modalities, access options and version records below.

Version specifications by release date

Versions and size variants within the same family are shown separately. Each point needs both a specification reference and a release date. Points are not joined, and larger parameters or context do not imply better results.

Unit: Token. Of 5 eligible versions, 0 have plotted values. 5 lack a value and 5 lack a release date; these gaps can overlap. Missing values are not zero.

No version has both a numeric value and documented release date for this metric. Check the version records or choose another metric. Listing dates and repository changes are not used as substitutes.

Full values & references for all four metrics

Context window · Token

No records meet both date and numeric evidence requirements.

Input token limit · Token

No records meet both date and numeric evidence requirements.

Max text output · Token

No records meet both date and numeric evidence requirements.

Published parameter count · B

No records meet both date and numeric evidence requirements.

Total context, input limits, maximum text output and parameter counts are shown separately, retaining approximate values. Parameters use verified published counts, not inferred active parameters. All versions, including undated specifications, remain in the version list.

Release & lifecycle history

Release & lifecycle events

3 sourced events by month, including releases, deprecations and retirements. One event can cover several versions. These are release events in the current catalog, rather than newly added listings.

  1. Deprecation noticeLegacy Sonar Chat Completions support ended →

    The legacy product API is no longer supported. Synchronous and streaming calls are progressively rewritten as Agent requests; asynchronous calls stop. This does not retire the current Agent Sonar models.

  2. Retirementsonar-reasoning removed →

    This API model was removed. The official recommendation is to migrate to Sonar Reasoning Pro.

  3. RetirementLegacy Sonar online models removed →

    Three legacy Sonar online API models were retired.

References & scope

Each version also lists its own specification and license references. A US developer brand. Hosted models’ original developer countries, deployment locations and supported regions are recorded separately. Catalog as of 2026-10-31.
