V4 context window: state the 1M limit instead of inheriting a 200K fallback (TASK-393) - #391
Conversation
…ated TASK-393. ClawBox sells V4 on its 1M context window and no box was getting it. A provider configured in openclaw.json overrides OpenClaw's bundled model catalog outright, so the fields we left out did not fall back to the canonical V4 spec — they fell back to the generic 200,000-token default. The provider definition omitted contextWindow, maxTokens and input on purpose, with a comment explaining that duplicating them would only create drift. That reasoning was sound and the premise was wrong. Reproduced on a real device running OpenClaw 2026.7.1 on 2026-08-17: with the fields absent `openclaw models list` resolved both V4 models to 200K; with them present it reports 1M, and a live session reports contextTokens=1,000,000. The static ClawBox AI catalog had a second, independent version of the same problem: it hardcoded 128,000 for both tiers, a number that was never V4's limit, so every model picker on the device under-reported the window even where the gateway had it right. It also advertised text+image on a text-only proxy. Fixes both, and backfills devices already in the field from the boot script. The migration recognises the three states a shipped box can be in — absent, an old explicit 128000, or a 200000 written back by an earlier run — and corrects all three for Flash and Pro alike. It deliberately does not touch a contextWindow it doesn't recognise: a value we never shipped is one somebody chose, and overruling that would be the migration picking a fight with its operator. maxTokens is only filled when absent for the same reason. Tests exercise the migration block extracted from the shipped .sh rather than a copy, so the suite fails if the script drifts. Remaining from the acceptance criteria: end-to-end validation on a real box through the update path, and confirmation of whether the proxy honours the declared 384K output ceiling or enforces something lower.

🦀 ClawReviewFresh PR washed in with the tide — here's the gist. This fix corrects ClawBox AI V4 model metadata that was silently capping context at 200 K (or 128 K) instead of the real 1 M limit. Three places are updated together: the static catalog served to model pickers, the provider definition written to openclaw.json at configure time, and a boot-time migration in gateway-pre-start.sh that corrects existing devices already in the field. The PR includes tests that run the actual migration block extracted from the shipped shell script. At a glance

Preserve a 131072 context-window value.
The migration contract corrects only absent, 128000, and 200000 values. This predicate also rewrites 131072. An operator who set a 131072-token cap will have that configuration changed to 1,000,000 on gateway startup. Remove 131072 from this migration set and add a regression test that preserves it.

384,000 was chosen as "384K" and shipped in #391. The upstream actually enforces 393,216 (384 x 1024): measured against the live proxy on 18.08, max_tokens=393216 returns 200 and 400000 returns 400 "the valid range of max_tokens is [1, 393216]". So every V4 session has been leaving 9,216 tokens of output on the table for no reason. The migration now corrects 384000 as well as filling an absent value. That number can only have come from the first version of this migration, so a box carrying it is carrying our rounding, not a decision its owner made — unlike the 8K cap someone sets deliberately, which is still left alone.

ClawBox sells V4 on its 1M context window and no box was getting it.
Why it was broken
A provider configured in
openclaw.jsonoverrides OpenClaw's bundled model catalog outright. The fields the provider definition left out therefore did not fall back to the canonical V4 spec — they fell back to the generic 200,000-token default.The omission was deliberate and documented: the old comment argued that restating
contextWindow/maxTokens/inputwould only create drift the next time DeepSeek bumps a number. Sound reasoning, wrong premise.Reproduced on a real device on OpenClaw 2026.7.1 (2026-08-17):
openclaw models listresolves both V4 models to 200KcontextTokens=1,000,000The static ClawBox AI catalog had a second, independent version of the same problem: hardcoded
128_000for both tiers — a number that was never V4's limit — so every model picker under-reported the window even where the gateway had it right. It also advertisedtext+imageon a text-only proxy.What changed
configure/route.ts— both tiers now statecontextWindow: 1_000_000,maxTokens: 384_000,input: ["text"], with the reason recorded so the next person doesn't "clean up" the duplication.catalog/route.ts—128_000→1_000_000,text+image→text.gateway-pre-start.sh— idempotent backfill for boxes already in the field.What the migration will and won't do
It recognises the three states a shipped box can be in — absent, an old explicit 128000, or a 200000 written back by an earlier run — and corrects all three, for Flash and Pro alike.
It deliberately leaves a
contextWindowit doesn't recognise alone. A value we never shipped is one somebody chose (a small-RAM box, a cost experiment), and stamping over it would be the migration picking a fight with its operator.maxTokensis only filled when absent, for the same reason.Verification
