GPT-6.1 Sol API

Use the exact model ID gpt-6.1-sol. GPT-6.1 Sol has a 1,050,000-token context window and a model output limit of 128,000 tokens. New integrations and tool-calling workflows should use OpenAI Responses.

Quick start

POST https://api.beatapi.io/v1/responses

import OpenAI from "openai";
const client = new OpenAI({
  apiKey: process.env.BEATAPI_API_KEY,
  baseURL: "https://api.beatapi.io/v1"
});
const response = await client.responses.create({
  model: "gpt-6.1-sol",
  input: "Suggest a minimal fix for a webhook handler that processes duplicate events.",
  reasoning: { effort: "medium" }
});
console.log(response.output_text);

curl --request POST \
  --url https://api.beatapi.io/v1/responses \
  --header 'Authorization: Bearer <BEATAPI_API_KEY>' \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "gpt-6.1-sol",
    "input": "Suggest a minimal fix for a webhook handler that processes duplicate events.",
    "reasoning": { "effort": "medium" }
  }'

Reasoning and request formats

Supported reasoning efforts are low, medium, high, xhigh, and max. Start with medium and evaluate the latency and answer quality for your workload. none and minimal are not supported by this model.

Use Responses for tool calls. For an existing SDK integration, consult the Text API format guide and the supported_endpoint_types returned by GET /v1/models. Request-format compatibility does not imply that every provider-specific option or tool is supported.

BeatAPI pricing

Prices below are USD per 1 million tokens, checked on September 30, 2026.

When input exceeds 272,000 tokens, the higher tier applies to the full request. Cache rates apply when the corresponding cache usage is reported. See the current price table before budgeting a workload.

Availability and usage

Call GET https://api.beatapi.io/v1/models with your BeatAPI key and confirm gpt-6.1-sol is enabled for the key’s group. Model availability and free-credit eligibility follow your account and key settings.

The same BeatAPI key and USD balance cover supported text models and other BeatAPI capabilities. Inspect the request ID, token usage, status, and settled charge in Dashboard usage logs.
