TensorZero
Abstract
[!CAUTION] Breaking Changes The Prometheus metric tensorzero_inference_latency_overhead_seconds will report a histogram instead of a summary. You can customize the buckets using gateway.metrics.tensorzero_inference_latency_overhead_seconds_buckets in the configuration (default: 1ms, 10ms, 100ms). [!WARNING] Planned Deprecations Deprecate the TENSORZERO_CLICKHOUSE_URL environment variable from the UI. Moving forward, the UI will query data through the gateway and does not communicate directly with ClickHouse. Rename the Prometheus metric tensorzero_inference_latency_overhead_seconds_histogram to tensorzero_inference_latency_overhead_seconds. Both metrics will be emitted for now. Rename the configuration field tensorzero_inference_latency_overhead_seconds_histogram_buckets to tensorzero_inference_latency_overhead_seconds_buckets. Both fields are available for now. New Feature Add optional include_raw_usage parameter to inference requests. If enabled, the gateway returns the raw usage objects from model provider responses in addition to the normalized usage response field. Add optional --bind-address CLI flag to the gateway. Add optional description field to metrics in the configuration. Add option to fine-tune Fireworks models without automatic deployment. & multiple under-the-hood and UI improvements (thanks @ecalifornica @achaljhawar @rguilmont)!
