AI Large Language Models (LLM)

MuApi gives you a unified API to query all major Large Language Models (LLMs) in production. Send a message prompt, get back a completion response or a live stream SSE, and control parameters like reasoning depth and web search — all with credit-based pricing on a single, shared credit balance.

  • Access Gemini, Claude, GPT, Grok, Qwen, Llama, DeepSeek and more via one endpoint
  • Support for standard async execution and real-time streaming
  • Credit-based pay-as-you-go pricing with no mandatory monthly commitments
  • Unified JSON schema for chat, reasoning, and document parsing

Quick Start

Every model in this category uses the same submit-then-poll API. Replace gpt-5-5 with any model endpoint from the list below.

# 1. Submit
curl -X POST https://api.muapi.ai/api/v1/gpt-5-5 \
  -H "x-api-key: $MUAPI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"Explain quantum computing in simple terms."}'
# → {"request_id":"abc123","status":"processing"}

# 2. Poll until completed
curl https://api.muapi.ai/api/v1/predictions/abc123/result \
  -H "x-api-key: $MUAPI_API_KEY"

Frequently Asked Questions

Which LLM model is best?

GPT 5.5 and Claude Opus 4.8 are the best for deep logic, complex coding, and multi-step reasoning. Gemini 3.5 Flash is highly optimized for rapid, real-time, low-latency applications. MuApi hosts all of them so you can benchmark quality vs. cost dynamically.

Do you support streaming?

Yes! Every LLM model has a streaming endpoint (e.g. `POST /api/v1/{model}/stream`) that pushes Server-Sent Events (SSE) for near-instant rendering in chat bubbles.
