210K Context on a 32 GB Arc Pro B70
Three identical cold starts, 179,525 prompt tokens, and a rollback regex that briefly became the main character.
Verdict
Admitted — the production route passed exact near-180K recall and the complete recovery, vision, reasoning, tool, and MTP suite.

Squeezing Qwen3.8 Until It Cried: A 46.9% Speedup and One Optimization Too Far
A 46.9% Qwen3.8 speedup, a production qualification, and the tempting 64K shortcut that failed when the benchmark got serious.
Promote the full-vocabulary checkpoint: 46.88% faster decode, qualified behavior, and no support for the later 64K shortcut.
Updating OpenClaw Is Always a Rollercoaster Ride, Never Boring
A healthy container, an unavailable Codex harness, dependencies in the wrong neighbourhood, and the rollback lever that became our favourite feature.
Recovered and patched — the official 2026.9.1 candidate failed its Codex gate; a validated custom 2026.9.2 image restored the workload. The fix is merged upstream, but a stock replacement remains pending.
An A/B OpenClaw Upgrade with an Actual Escape Route
How we promoted OpenClaw 2026.8.2 from a quiesced clone, kept 2026.8.1 ready for rollback, and removed several safety checks that were only pretending to help.
Accepted — the current-definition-derived A/B cutover moved production from 2026.8.1 to 2026.8.2 while preserving the original slot as an immediate rollback.

How ubatch=1024 Won the Benchmark and Lost the Ability to Speak
A 6% prefill improvement, five failed conversations, and one tiny silicon cult chanting the unused32 token.
Rejected — the narrow prefill win concealed catastrophic generation and tool-call failures.
Qwen3.8 Flash-Next on One Arc Pro B70
Fifteen tokens per second, one extremely narrow memory edge, and several acceleration ideas asked to leave the laboratory.
Promising isolated batch-worker profile, not a production route.
