Because a free model that cannot do your task costs you infinite money in wasted time.\n\n## Full Pricing Table\n\n### Proprietary API Models (by output cost)\n\n| Model | Provider | Input / 1M tokens | Output / 1M tokens | Reasoning | Coding | Free Tier |\n|-------|----------|-------------------|---------------------|-----------|--------|-----------|\n| Gemini 3 Flash | Google | $0.15 | $0.60 | 82 | 80 | Yes |\n| Claude Haiku 4.5 | Anthropic | $1.00 | $5.00 | 82 | 84 | No |\n| Grok 4.20 | xAI | $2.00 | $6.00 | 85 | 88 | No |\n| Gemini 3.1 Pro | Google | $2.00 | $12.00 | 93 | 91 | Yes |\n| Claude Sonnet 4.6 | Anthropic | $3.00 | $15.00 | 91 | 93 | No |\n| GPT-5.4 | OpenAI | $5.00 | $15.00 | 95 | 92 | No |\n| Grok 4.1 | xAI | $3.00 | $15.00 | 91 | 90 | No |\n| Claude Opus 4.6 | Anthropic | $5.00 | $25.00 | 96 | 97 | No |\n| GPT-5.4 Thinking | OpenAI | $10.00 | $40.00 | 98 | 93 | No |\n\n### Open Source API Models (by output cost)\n\n| Model | Provider | Input / 1M tokens | Output / 1M tokens | Reasoning | Coding | License |\n|-------|----------|-------------------|---------------------|-----------|--------|---------|\n| DeepSeek V3.2 | DeepSeek | $0.27 | $1.10 | 88 | 88 | MIT |\n| MiniMax M2.7 | MiniMax | $0.53 | $0.53 | 90 | 95 | Modified MIT |\n| DeepSeek R1 | DeepSeek | $0.55 | $2.19 | 92 | 88 | MIT |\n| Mistral 3 | Mistral | $2.00 | $6.00 | 86 | 87 | Apache 2.0 |\n| Command R+ | Cohere | $2.50 | $2.50 | 82 | 78 | CC-BY-NC 4.0 |\n\n### Free Self-Hosted Models (hardware cost only)\n\n| Model | Provider | Active Parameters | Min Hardware | Reasoning | Coding | License |\n|-------|----------|-------------------|-------------|-----------|--------|---------|\n| Nemotron-Cascade 2 | NVIDIA | 3B | 1x RTX 4090 | 88 | 90 | NVIDIA Open |\n| Gemma 4 (26B MoE) | Google | 3.8B | 1x RTX 4090 | 84 | 83 | Apache 2.0 |\n| Phi-4 | Microsoft | 14B | 1x RTX 3060 | 78 | 80 | MIT |\n| SmolLM3 3B | Hugging Face | 3B | 1x RTX 3060 | 68 | 70 | Apache 2.0 |\n| Qwen 3.5 (Q4) | Alibaba | 17B | 1x RTX 4090 | 91 | 92 | Apache 2.0 |\n| Llama 4 Maverick (Q4) | Meta | 17B | 2x RTX 4090 | 87 | 82 | Llama Community |\n| DeepSeek V3.2 (Q4) | DeepSeek | 37B | 2x A100 | 88 | 88 | MIT |\n| GLM-5 (Q4) | Zhipu AI | 40B | 2x A100 | 90 | 93 | MIT |\n\n## Quality-Per-Dollar Rankings\n\nThe real question is not \"what is cheapest?\" but \"what gives me the most capability per dollar?\" Here is how each model stacks up, measuring the average of reasoning + coding scores divided by output cost per million tokens.\n\n### Best Value: Proprietary APIs\n\n**Tier 1 -- Exceptional value:**\n\n1. **Gemini 3 Flash** -- $0.60 output, 81 average quality. By far the most tokens-per-dollar for any proprietary model. For high-volume classification, summarization, and extraction, nothing touches this.\n\n2. **Gemini 3.1 Pro** -- $12.00 output, 92 average quality. The best frontier model for the price. 93/100 reasoning at $2/$12 is the sweet spot where quality and cost intersect.\n\n3. **Grok 4.20** -- $6.00 output, 86.5 average quality. Surprisingly good value with the lowest hallucination rate of any model. The fast tier pricing punches above its weight.\n\n**Tier 2 -- Good value:**\n\n4. **Claude Haiku 4.5** -- $5.00 output, 83 average quality. Solid for Anthropic-ecosystem users who need speed over maximum quality.\n\n5. **Claude Sonnet 4.6** -- $15.00 output, 92 average quality. Matches Gemini 3.1 Pro quality at higher cost, but better coding and writing.\n\n**Tier 3 -- Premium (justified for specific use cases):**\n\n6. **GPT-5.4** -- $15.00 output, 93.5 average quality. You are paying for the ecosystem as much as the model.\n\n7. **Claude Opus 4.6** -- $25.00 output, 96.5 average quality. The coding premium. Only justified when you genuinely need the best.\n\n8. **GPT-5.4 Thinking** -- $40.00 output, 95.5 average quality. The reasoning ceiling. Only for genuinely hard problems.\n\n### Best Value: Open Source APIs\n\n1. **MiniMax M2.7** -- $0.53 output, 92.5 average quality. The best quality-per-dollar in the entire AI market. 95/100 coding at 53 cents per million output tokens is almost disrespectful to the competition.\n\n2. **DeepSeek V3.2** -- $1.10 output, 88 average quality. The safe default for budget-conscious API use. Strong across the board, MIT license, established provider.\n\n3. **DeepSeek R1** -- $2.19 output, 90 average quality. The math specialist on a budget. 94/100 math at $2.19 output is remarkable.\n\n### Best Value: Self-Hosted\n\n1. **Nemotron-Cascade 2** -- Single RTX 4090, 89 average quality. The most impressive model-per-FLOP ever released. 90/100 coding on consumer hardware.\n\n2. **Qwen 3.5 (quantized)** -- Single RTX 4090, 91.5 average quality. Higher raw quality than Cascade 2, but needs Q4 quantization to fit on consumer hardware.\n\n3. **Gemma 4 (26B MoE)** -- Single RTX 4090, 83.5 average quality. Solid general-purpose option from Google, Apache 2.0 licensed.\n\n## Cost Scenarios\n\n### Scenario 1: Startup with 1M tokens/day\n\nMonthly volume: ~30M input tokens, ~10M output tokens.\n\n| Option | Monthly Cost |\n|--------|-------------|\n| Gemini 3 Flash | $10.50 |\n| DeepSeek V3.2 API | $19.10 |\n| MiniMax M2.7 API | $21.20 |\n| Gemini 3.1 Pro | $180.00 |\n| Claude Sonnet 4.6 | $240.00 |\n| GPT-5.4 | $300.00 |\n| Claude Opus 4.6 | $400.00 |\n| Self-hosted Nemotron-Cascade 2 | ~$0 (own hardware) |\n\n**Recommendation:** Start with Gemini 3 Flash or DeepSeek V3.2 API. Upgrade to Gemini 3.1 Pro or Sonnet 4.6 when quality requirements increase.\n\n### Scenario 2: Enterprise with 100M tokens/day\n\nMonthly volume: ~2B input tokens, ~1B output tokens.\n\n| Option | Monthly Cost |\n|--------|-------------|\n| Gemini 3 Flash | $900 |\n| DeepSeek V3.2 API | $1,640 |\n| Self-hosted DeepSeek V3.2 | $15,000-20,000 (8x A100 rental) |\n| Gemini 3.1 Pro | $16,000 |\n| Claude Sonnet 4.6 | $21,000 |\n| GPT-5.4 | $25,000 |\n| Claude Opus 4.6 | $35,000 |\n\n**Recommendation:** Self-host DeepSeek V3.2 or use the API. For quality-critical tasks, route to Gemini 3.1 Pro or Claude Sonnet 4.6. Self-hosting breaks even with proprietary APIs at this volume.\n\n### Scenario 3: Individual developer\n\nMonthly volume: ~2M input tokens, ~1M output tokens (moderate daily use).\n\n| Option | Monthly Cost |\n|--------|-------------|\n| Gemini 3 Flash | $0.69 |\n| Gemini 3.1 Pro (free tier) | $0 (within limits) |\n| DeepSeek V3.2 API | $1.64 |\n| Claude Haiku 4.5 | $7.00 |\n| OpenAI Go plan | $8.00/month (flat) |\n| Claude Sonnet 4.6 | $21.00 |\n| ChatGPT Plus | $20.00/month (flat) |\n| Claude Pro | $20.00/month (flat) |\n\n**Recommendation:** Gemini 3.1 Pro free tier for experimentation. DeepSeek V3.2 API for production use. Claude Pro or ChatGPT Plus subscription for interactive daily use.\n\n## The Free Options\n\nModels you can use right now without spending anything:\n\n1. **Gemini 3.1 Pro via Google AI Studio** -- Full frontier model, free tier with rate limits. Best free option for quality.\n2. **Gemini 3 Flash via Google AI Studio** -- Free tier, blazing fast, 1M context.\n3. **Self-hosted open models via Ollama** -- Nemotron-Cascade 2, Gemma 4, Phi-4, SmolLM3, and dozens more. Free if you own a GPU.\n4. **DeepSeek API** -- Generous free tier for V3.2 and R1.\n5. **Google Antigravity IDE** -- Free AI coding IDE with Gemini and Claude built in.\n6. **Qwen/Llama/Mistral via HuggingFace** -- Download and run locally. Free forever.\n\n## The Verdict\n\n**If cost is your only constraint:** Self-host Nemotron-Cascade 2 on consumer hardware (free after GPU purchase) or use Gemini 3 Flash via API ($0.15/$0.60). Both are competent for routine tasks.\n\n**If you want the best value without sacrificing quality:** Gemini 3.1 Pro at $2/$12 or MiniMax M2.7 at $0.53/$0.53. Both deliver near-frontier quality at a fraction of premium pricing.\n\n**If you want a budget coding model:** MiniMax M2.7 at $0.53 is the best quality-per-dollar for coding. DeepSeek V3.2 at $0.27/$1.10 is the best for general-purpose use.\n\n**The uncomfortable truth:** Most people are overpaying for AI. Claude Opus 4.6 and GPT-5.4 are exceptional models, but Gemini 3.1 Pro delivers 90-95% of their capability at 40-60% of the cost. Unless you have a specific reason to need the absolute frontier -- coding accuracy, writing quality, maximum reasoning ceiling -- the mid-tier models are where the value is. The models at $0.15-$2.00 per million tokens are good enough for most real-world tasks. The models at $5-$25 are for when \"good enough\" is not good enough.","content_length":8824,"generated_at":"2026-04-24"}
