Question 1

Which has a larger context window, GPT-5.4 Image 2 or Llama 3.1 70B Hanami x1?

Accepted Answer

GPT-5.4 Image 2 has a larger context window: 272K tokens vs 16K. For long documents, large codebases, or extended agent sessions, the larger context window reduces the need to chunk inputs or summarize history.

Question 2

When should I use GPT-5.4 Image 2 vs Llama 3.1 70B Hanami x1?

Accepted Answer

Choose based on your primary constraint. If you need maximum context capacity, pick the model with the larger window. If cost is your main concern, compare input/output pricing for your expected token ratio. For latency-sensitive applications, check the speed tier of each model.

Question 3

Can Mem0 reduce the context I need for GPT-5.4 Image 2 or Llama 3.1 70B Hanami x1?

Accepted Answer

Yes. Mem0's persistent memory layer stores user preferences, past decisions, and frequently referenced context outside the model's context window. Instead of replaying full conversation history, only relevant facts are injected — typically reducing input tokens by 70–90%. This makes even smaller context windows practical for long-running applications.
