Frontier AI Models 2026
The frontier-model releases worth tracking in 2026, with official pricing, published benchmarks and open-weight options.
Frontier models move fast and pricing changes with every release. This collection keeps the current generation of frontier models in one place: what each one costs, what the official benchmarks actually say, and where the weights or the API are available. Start with a model profile for the product overview, then read the matching pricing and deployment guide for the numbers you need to make a decision.
Guides and deep dives
Grok 4.7 Pricing, Benchmarks and API Access (2026)

Frequently asked questions
What are the frontier AI models in 2026?
The generation AISpotNav currently tracks is Grok 4.7 from xAI and DeepSeek V4 Pro from DeepSeek, plus the products built on frontier-grade models such as Claude and Perplexity AI. Each entry links to official pricing and official benchmark data rather than third-party summaries.
How much does Grok 4.7 cost per million tokens?
xAI lists $2.00 per million input tokens and $6.00 per million output tokens for Grok 4.7, with a 500,000 token context window. The full price list, including the Voice and Imagine APIs, is in the Grok 4.7 pricing guide.
Is DeepSeek V4 Pro open source?
Yes. The DeepSeek-V4-Pro weights are published on Hugging Face under the MIT license, with 1.6T total parameters, 49B active per token and a 1,000,000 token context window.
Should I use a frontier model or a free-tier API?
Frontier models are the strongest option for long-horizon coding and agentic work, but they are metered per token. If you are prototyping or building internal tooling, the free LLM APIs collection lists providers with recurring free tiers that cost nothing to start.
