Clarify gpt-5.3-codex-spark context window metadata
Summary
Please clarify the authoritative context-window metadata for gpt-5.3-codex-spark.
The Codex model list exposes gpt-5.3-codex-spark, but its public context-window value is hard to verify. The public bundled model catalog appears to include gpt-5.3-codex metadata, but I could not find an explicit gpt-5.3-codex-spark entry.
Existing user reports also show Spark status output with an effective context window around 258K, while some Codex remote-model tests use 273K default and 400K max-style context-window values. This makes it unclear which value is intended for Spark.
Expected behavior
Please document or expose the intended values for Spark:
- total context window
- effective window shown by
/status - whether the effective value reserves output or compaction budget
- whether
model_context_windowcan override it and what max value it clamps to - whether Spark should appear in the public bundled model catalog
Actual behavior
Spark is visible as a selectable Codex model, but its context-window semantics are unclear from public docs and repo metadata.
