DSv4 Flash Tool Call Stability Issues at Long Context
captaintobs · reddit · 2026-08-21
A user running DSv4 Flash via jasl/vllm on 4 Spark instances reported that tool calls start failing (e.g., missing characters like '>') after about 100k context tokens. While the model offers high throughput (50 tps single, >100 tps aggregate), it lacks stability. GLM 5.2 is found more efficient and correct but significantly slower (25 tps).
