Capability support
| Feature | Status | Notes |
|---|---|---|
| Image rendering | unsupported2026-07-08T15:41:12.127Z | Tool was called and the model echoed the probe's call-id back to the user — but a terminal/code-exec surface can't render images or iframes. Default unsupported. |
| Animated GIF | unsupported2026-07-08T15:41:23.221Z | Tool was called and the model echoed the probe's call-id back to the user — but a terminal/code-exec surface can't render images or iframes. Default unsupported. |
| SVG | unsupported2026-07-08T15:41:33.186Z | Tool was called but the model did not echo the probe's call-id. Could be a render (no quote needed) or a swallow. Default unsupported for tier. |
| HEIC | unsupported2026-07-08T15:41:41.079Z | Tool was called and the model echoed the probe's call-id back to the user — but a terminal/code-exec surface can't render images or iframes. Default unsupported. |
| MCP Apps HTML widget | unsupported2026-07-08T15:41:55.767Z | Tool was called and the model echoed the probe's call-id back to the user — but a terminal/code-exec surface can't render images or iframes. Default unsupported. |
| ChatGPT Apps SDK component | unsupported2026-07-08T15:42:04.381Z | Tool was called and the model echoed the probe's call-id back to the user — but a terminal/code-exec surface can't render images or iframes. Default unsupported. |
| Markdown: basic | supported2026-07-08T15:42:13.219Z | Markdown content was returned and the model echoed it (including the call-id) back to the user. |
| Markdown: tables | partial2026-07-08T15:42:32.868Z | Tool was called and the model echoed the probe's call-id — but behavioral can't tell whether the client actually rendered the markdown variant (table/code/math/diagram/image/task/URL) vs. surfaced the source. Prefer vision-tier for a definitive answer. |
| Markdown: code blocks | partial2026-07-08T15:42:42.117Z | Tool was called and the model echoed the probe's call-id — but behavioral can't tell whether the client actually rendered the markdown variant (table/code/math/diagram/image/task/URL) vs. surfaced the source. Prefer vision-tier for a definitive answer. |
| Markdown: images | partial2026-07-08T15:42:51.183Z | Tool was called and the model echoed the probe's call-id — but behavioral can't tell whether the client actually rendered the markdown variant (table/code/math/diagram/image/task/URL) vs. surfaced the source. Prefer vision-tier for a definitive answer. |
| Markdown: task lists | partial2026-07-08T15:42:59.239Z | Tool was called and the model echoed the probe's call-id — but behavioral can't tell whether the client actually rendered the markdown variant (table/code/math/diagram/image/task/URL) vs. surfaced the source. Prefer vision-tier for a definitive answer. |
| URL autolinking | partial2026-07-08T15:43:07.127Z | Tool was called and the model echoed the probe's call-id — but behavioral can't tell whether the client actually rendered the markdown variant (table/code/math/diagram/image/task/URL) vs. surfaced the source. Prefer vision-tier for a definitive answer. |
| MCP resources | supported2026-07-08T15:43:18.844Z | The model's reply quoted the render token that exists only in the resource content block's body — the client surfaced the resource. |
| MCP prompt templates | unknown2026-07-08T15:43:28.896Z | MCP protocol feature; no wire-level evidence found in the captured stream — defer to vision or manual review. |
| MCP elicitation | unsupported2026-07-08T15:43:38.708Z | Client did not declare the elicitation capability during MCP initialize. |
| MCP sampling | unsupported2026-07-08T15:43:49.758Z | Client did not declare the sampling capability during MCP initialize. |
| MCP structured content | unsupported2026-07-08T15:43:59.083Z | The model echoed the tool response's nonce but referenced none of the structuredContent payload fields — the client likely surfaced only the text fallback. |
