What's the cheapest AI model in 2026?

For general use, DeepSeek V3 ($0.014 input / $0.028 output per 1M) and Llama 4 Scout ($0.08 / $0.30) are the cheapest in the table. For complex reasoning, Qwen and DeepSeek R1 are the most competitive against o3 or GPT-5.4. Filter by "Budget" category in the comparator to see the current ranking.

How does GPT-5.4 differ from Claude Opus 4.6?

GPT-5.4 is faster, half the input price ($2.50 vs $5 per 1M) and has better function-calling and batch API ergonomics. Claude Opus 4.6 wins at long-form writing, large codebases and strict multi-step instructions. Both ship 1M-token context windows. If cost is no issue: Claude for long text and craft; GPT-5.4 for latency and volume.

Are the prices in this tool up to date?

Yes. We review each of the 11 providers' official pages every month. The "Prices April 2026" badge next to the comparator shows the last revision. If you spot anything stale, tell us and we'll fix it within 24 hours.

What's the difference between flagship, mid-tier, budget and reasoning models?

Flagship: the provider's top model (GPT-5.4, Claude Opus 4.6, Gemini 3.1 Pro). Mid-tier: a trimmed version with ~80% of the quality at ~30% of the cost (GPT-5.4 Mini, Claude Sonnet). Budget: optimised for massive volume (GPT-5.4 Nano, Claude Haiku, DeepSeek V3). Reasoning: trained to think step-by-step — slower but better at hard problems (o3, DeepSeek R1, Sonar Reasoning).
