Testing doesn’t require a top-up first

AiHubMix’s (aihubmix.com) onboarding differs from most relay platforms: create an account and get a permanent free testing quota — calling Claude/GPT/Gemini and other mainstream models doesn’t require paying upfront.

This free tier isn’t a time-limited trial, nor is it capped at a handful of demo calls — it’s an ongoing allowance for low-frequency use. During the prototyping phase, you can get your code working and finish testing your integration, then decide whether to top up for production use.

Prompt Caching: how much money can this actually save

AiHubMix is one of the few domestic relay platforms that explicitly supports Anthropic Prompt Caching. The basic mechanism:

  • Content that repeats in a request’s prefix is marked “cacheable” (by adding a cache_control field)
  • The first write to cache is billed at the normal rate; subsequent reads that hit the cache are billed at just 10% of the price
  • Cache validity is roughly 5 minutes (a hit requires a repeat call within the TTL)

How much does it actually save? Say your AI application sends a 2000-token system prompt with every request, at 10,000 calls per day:

  • Without Caching: daily system-prompt cost = 2000 × 10,000 × $5/M = $0.1/day, or $36.5/year
  • With Caching (90% hit rate): write cost + read cost ≈ 19% of the original

Long conversations, RAG applications, and agents with large system prompts benefit the most.

# AiHubMix Prompt Caching integration
import anthropic

client = anthropic.Anthropic(
    api_key="your key",
    base_url="https://api.aihubmix.com"
)

response = client.messages.create(
    model="claude-opus-4-8",
    max_tokens=1024,
    system=[{
        "type": "text",
        "text": "You are a professional code reviewer. Guidelines: ...(long system prompt)...",
        "cache_control": {"type": "ephemeral"}  # mark as cacheable
    }],
    messages=[{"role": "user", "content": "Help me review this code"}]
)

Price and positioning

Beyond the free testing tier, AiHubMix charges pay-as-you-go plus tiered discounts at higher volume, with no monthly fee. Overall pricing is mid-tier — not the cheapest, but the combination of a free tier and Prompt Caching can meaningfully cut real-world cost in specific scenarios, so total cost of ownership isn’t necessarily higher than a low-price platform’s.

Check aihubmix.com for current pricing. Current promos: 10% off all models (except the Claude series), glm-5.2 up to 50% off daily 14:00–23:59 UTC, and qwen3.8-max-preview consuming credits at 20% of the standard rate for a limited time.

Model coverage

Covering 800+ models including Claude/GPT/Gemini/Grok/DeepSeek/Qwen/Kimi/GLM/MiniMax/Doubao, with image/video generation (qwen-image, doubao-seedance, Kling, etc.):

  • Claude: Fable 5, Opus 4.8, Sonnet 4.6, Haiku 4.5 (Prompt Caching supported across the line)
  • GPT: GPT-5.5, GPT-4o, o-series reasoning models
  • Gemini: Gemini 3.5 Flash/Pro
  • DeepSeek: V4 Pro, V4 Flash

Also covers image/video generation (qwen-image, doubao-seedance, Kling, etc.) — no longer limited to pure-text scenarios.

Documentation

AiHubMix’s documentation is a key differentiator from rougher relay platforms — the integration guide, Prompt Caching usage notes, and common error handling are relatively complete. For teams integrating an AI API for the first time, having good docs noticeably lowers the friction.

Good fit and poor fit

ScenarioNotes
Prototyping / MVP stageStart at zero cost, no worrying about testing-phase fees
Long conversations / long-context ClaudePrompt Caching cuts repeated-token cost by 90%
RAG / AI agent productsLarge system prompts benefit significantly from cache hits
Chasing the absolute lowest unit priceMid-tier pricing; TokenRiver (billed at the 1¥=$1 official rate) or yunwu is cheaper
Need multimodal (image/video)Doesn’t cover Midjourney / Suno
Strict SLA requirementsNo public SLA numbers — not a good fit

For enterprise scenarios requiring a signed Data Processing Agreement (DPA), we’d recommend evaluating CloseAI’s enterprise-grade agreement offering directly — AiHubMix currently has no public DPA signing process.

Information verified 2026-08-11. Consult aihubmix.com’s official documentation before using Prompt Caching — the cache hit rate depends on how well your call frequency matches the 5-minute TTL.

  • RunPod: per-second billed GPU cloud, community compute pool, 70% cheaper than AWS
  • Jina AI API: full-stack multimodal embeddings + rerank + reader, low-latency CDN for RAG scenarios
  • RunAPI: high-quality, high-speed, mainland direct connect, a pick for speed-focused developers
  • MoleAPI: single API unifying GPT-4o/Claude/Gemini, <50ms direct-connect latency, OpenAI-format compatible, free credit for new signups

Pros

  • Permanent free testing tier: test mainstream models like Claude/GPT/Gemini at low call frequency with no payment required — validate your integration at zero cost
  • Supports Anthropic Prompt Caching, which can significantly cut API costs for long conversations and repeated-prefix scenarios
  • Solid documentation and a good developer integration experience, well suited to technical teams onboarding quickly

Cons

  • Mid-tier pricing — the standard rate once you exceed the free tier isn't in the lowest-price bracket
  • The free tier has quota limits; high-volume use cases need to upgrade to paid
  • Limited public data on latency numbers and independent stability testing
