status='ready' — 80 tokens of a real answer. The tint rides one chart token's alpha (never a green-to-red hue ramp), so it survives colour blindness and greyscale; tokens under the threshold add a dotted underline as a second, non-colour channel. Hover or Tab into the strip and use ←/→ to walk tokens, ↑/↓ to change line, Escape to dismiss the panel. Position 35 (' five') is the one the sampler took outside its own top-k.

status='ready' · tint='probability' with the slider hidden — the same 80 tokens read the other way round: strong tint now means the model was sure. Same data, inverted question, one prop.

status='ready' · the payloads that break a naive strip: a newline token (visible ↵ and a real line break), a 38-character token, an effectively impossible one printed as ≤0.01% instead of a rounded 0%, a position whose top_logprobs came back empty, a token sampled at rank 3, and a zero-length token drawn as ∅. Nothing is trimmed — a token's leading space is part of the token.

status='empty' — logprobs simply were not requested for this response. Not a failure, and it says how to get them.

No token probabilities for this response. Send the request with logprobs enabled to inspect it here.

status='loading' — the run record hasn't arrived. The skeleton chips are fixed widths, so a screenshot is stable, and they stop pulsing under prefers-reduced-motion.

status='error' — the run record itself failed to load, which is a different failure from a model that answered badly. role=alert plus a retry you wire yourself.
