Who should pick which

  • Solo founder building a reliable AI customer support agent
    Pick: Temporal AI

    Temporal's durable execution ensures workflows survive crashes, retry API calls, and pause for human review—critical for production support.

  • Hobbyist wanting infinite chat with Llama 3 on a single GPU
    Pick: Attention Sinks

    Attention Sinks allows endless conversation without VRAM growth, perfect for low-resource setups. No cost, quick setup.

  • Team implementing a multi-step financial transaction system
    Pick: Temporal AI

    Temporal's Saga pattern, compensating transactions, and automatic retries guarantee data consistency across distributed steps.

  • Researcher benchmarking very long context LLMs
    Pick: Attention Sinks

    Attention Sinks enables stable perplexity beyond millions of tokens, ideal for studying long-term coherence without retraining.

  • Enterprise deploying AI agents with human-in-the-loop
    Pick: Temporal AI

    Temporal's signals and pause/resume allow seamless human oversight, and its visibility UI provides auditing—essential for compliance.
