• Gemini 1.5 Pro — Long context (1M), multimodal
• Gemini 2.5 Pro — Best for complex reasoning

Strengths

• Cheapest pricing
• Massive context window (1M tokens)
• Native multimodal (video, audio in)
• Google's infrastructure

Pricing

Gemini 2.0 Flash: $0.10 / $0.40
Gemini 1.5 Pro: $1.25 / $5.00

Groq

Models

• Llama 4 Scout — Fast inference
• Mixtral 8x7B — Open weights
• Gemma 2 9B — Google's open model

Strengths

• Fastest inference (<100ms TTFT)
• Best for real-time applications
• Cost-effective
• No rate limits (high volume)

Pricing

Groq is significantly cheaper, around $0.1-0.8/1M tokens

Kapan Pilih Apa?

Use OpenAI if:

• You need reliability and mature ecosystem
• Building consumer apps
• Need best-in-class performance

Use Anthropic if:

• Safety and ethics are paramount
• Long document analysis
• Complex coding tasks

Use Google if:

• Cost is major constraint
• Need long context (1M tokens)
• Need native multimodal

Use Groq if:

• Real-time applications (chat, voice)
• High volume, cost-sensitive
• Running open models

Multi-Provider Strategy

Production apps biasanya implement provider switching:

const model = getModel(config.provider, config.model)

async function generateWithFallback(prompt: string) {
  const providers = ['openai', 'anthropic', 'google']
  for (const provider of providers) {
    try {
      return await callProvider(provider, prompt)
    } catch (e) {
      if (isRateLimitError(e)) continue
      throw e
    }
  }
}

Pilih provider berdasarkan use case spesifik. Tidak ada satu provider yang terbaik untuk semua situasi.
