Questions

What is the best alternative to Grok 4 in 2026?
On blended token price, DeepSeek-V4-Pro is the cheapest comparable option — about 11× cheaper than Grok 4. Price is only half the decision: a model that costs 70% less but needs a second attempt on hard prompts is not a saving.
Which alternative is cheapest for output-heavy work?
Rank on the output column rather than the blended figure. Reasoning and agentic loops bill their thinking as output, so a model with cheap input and expensive output can end up the most costly option on the page despite looking competitive here.
Do these alternatives have the same context window?
No — the context column varies by more than 8× across this table. If you are feeding whole documents or codebases, filter on window size first and only then compare price, because a cheaper model that cannot hold your input is not an alternative at all.
