Specifications

Provider-documented facts. “Not collected” means we have not verified that field yet, not that the feature is unsupported.

Context / input limit
1,000,000 tokensSource for Context / input limit (opens in a new tab)

Exact numeric context from the documented model-list response, corroborated by the model catalog. Shared context, not an additional independent input allowance.

Maximum input tokens
Not collected
Maximum output
32,768 tokensSource for Maximum output (opens in a new tab)

Exact max_completion_tokens in the provider response example; the overview rounds this to 32K.

Input modalities
TextSource for Input modalities (opens in a new tab)

File and image input is converted to text by OCR. The underlying language model does not receive the original image.

Reasoning
SupportedSource for Reasoning (opens in a new tab)

Explicit reasoning model. Exact controls, reasoning-token accounting and exposed reasoning content are not fully documented.

Tool calling
SupportedSource for Tool calling (opens in a new tab)

Function calling is documented for the Sabiá 4 family; integrated server-side tools have separate model and streaming restrictions.

Structured output
SupportedSource for Structured output (opens in a new tab)

Provider-wide Responses API JSON-schema support, with examples using sabia-4. Subset only: up to 100 object properties, five nesting levels, 15,000 total schema-name characters and 500 enum values. Not all JSON Schema constraints are supported.

Streaming
SupportedSource for Streaming (opens in a new tab)

Text streaming is supported. Integrated web search, code execution and Data Ocean require stream:false; asynchronous Batch has no streaming.

Batch processing
SupportedSource for Batch processing (opens in a new tab)

Rates published for this model and BR-SP. One model per JSONL file, at most 50,000 requests / 200 MB, 24-hour completion window; completed output files are kept for 30 days. Expiration is possible.

Fine-tuning
Not supportedSource for Fine-tuning (opens in a new tab)

Provider states customer fine-tuning is not offered currently and recommends RAG for customization.

Knowledge cutoff
Not collected
Release date
2026-06-23Source for Release date (opens in a new tab)

Public API launch announcement.

Parameters
Not disclosedSource for Parameters (opens in a new tab)

The provider explicitly does not disclose exact parameter counts.

Architecture
TransformerSource for Architecture (opens in a new tab)

Exact base checkpoint and dense/MoE configuration are not identified. The training blog’s trillion-parameter cost exercise is illustrative, not this model’s specification.

Languages
PortugueseSource for Languages (opens in a new tab)

Documented specialization, not a claim that other languages are unsupported.

Context caching
SupportedSource for Context caching (opens in a new tab)

Automatic shared-prefix reuse; minimum eligible length and retention duration are not specified.

Published price
Brazilian reais (BRL), per 1M tokens; standard, night, Flex, Batch and cached-input rates vary by endpoint.Source for Published price (opens in a new tab)
fileProcessing
OCR text extraction from PDFs and PNG/JPEG images; extraction charges can be additionalSource for fileProcessing (opens in a new tab)
integratedTools
Web search, Page reading, Code execution, Data OceanSource for integratedTools (opens in a new tab)

Server-side agent workflow returns only its final response and optional generated artifacts. Intermediate reasoning/tool calls are not exposed.

Rate conditions

  1. BRL per million tokens. Cache hits retain their own 75% input discount. Batch, Flex and night rates apply only to uncached input and output and are mutually exclusive. Night hours are 22:00–06:00 BRT. Flex is capacity-dependent and may queue up to five minutes or return 429. No currency conversion is applied.
  2. Additional server-side tool fee, separate from token charges. Integrated tools require stream:false. A web-search request may perform both searches and page reads. Data Ocean can also trigger search, reading and code fees. No BR-SP tool-fee premium is specified.
  3. Additional charge per PDF page, separate from model tokens. Repeated extraction can be billed again; keep the returned extracted text for subsequent requests. The level setting does not apply to other file types.

Data & enterprise terms

Provider says API inputs/outputs are not used for model training. Normal content is discarded after generation, but error/observability logs may retain request content up to 30 days and infrastructure logs up to 18 months. Batch output files have a separate 30-day retention period; prompt-cache lifetime is unspecified. Chat/app conversations have different storage rules.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.
