Modern LLM rate limiting is a multi-dimensional throughput constraint that evaluates RPM, TPM, RPD and TPD/consumption limits simultaneously, returning HTTP 429 as soon as any dimension hits its ceiling.

UnverifiedRPM and TPM are two orthogonal dimensions of model API rate limiting: RPM constrains call frequency, independent of request body size; TPM constrains the total number of Tokens consumed per unit of time, and both take effect simultaneously, with a 429 returned as soon as either is hit first.70% similarVerifiedWhen running local LLMs, VRAM capacity is often more critical than computational speed, as VRAM capacity directly determines which models can be run.67% similarUnverifiedBandwidth-bound means data transfer speed cannot keep up with computation speed, which is common in scenarios with large weights but low compute volume (such as single-step LLM decoding), and quantization to compress weight size is an effective approach.66% similarUnverifiedLLM inference is typically bottlenecked by memory bandwidth rather than computation, and quantization improves throughput by reducing memory bandwidth requirements.65% similarVerifiedThe Prefill stage of LLM inference is compute-intensive with GPU utilization close to 100%, while the Decode stage is memory-bandwidth-intensive with the bottleneck being HBM VRAM bandwidth.65% similar
