Local vs. API LLMs: Cost, Performance, and Privacy Trade-offs

Running large language models locally versus using API-based services presents a complex cost-benefit analysis dependent on usage volume and specific constraints. While API models incur costs per use, local models require significant upfront investment in hardware and engineering. A key trade-off involves quantization, where techniques like Q4_K_M on an RTX 5070 Ti can double throughput with minimal loss in embedding similarity, but this comes with limitations on model size and precision. Ultimately, factors such as privacy requirements and data residency can dictate the choice, overriding pure cost considerations. AI

    The real trade-off between an API model and a local one

    <p>An API model costs nothing until the bill arrives, and a local model costs everything up front: hardware, quantisation loss, engineering time, before it answers a single question. Which one is cheaper depends on volume and constraints, not on which sounds more modern.</p> <p><…
