Unverified 3D clips are being treated as Gemini 4, including a floatplane versus Opus 5.5, while Google has only confirmed that the model is in early post-training.
A coding agent matched a classic game closely only after it could run the original, compare screenshots, and port an existing open-source room renderer.
OpenAI is running a months-long review of unexpected agent behavior, has notified dozens of third parties, and says most cases so far are low severity.
The claude-sonnet-5-5 slug in Droid 0.228.0 is strong staging evidence, but Anthropic has not announced Sonnet 5.5 and a registry string is not a release.

One token from GLM-5.3-Flash can score a fixed option list, matching Jev on Privatemode's text tests while costing more and accepting images.
Make a short Opus 5.5 cartoon by cloning ClaudeAnimationBase, prompting Claude Code to storyboard before it draws, checking contact sheets, and rendering the MP4 with headless Chrome and ffmpeg.
If coding agents use your language, give them explicit types, a way to query the program, and runtime state they can inspect.
Holding the token mix fixed, one illustrative Claude Code task costs about $2.40 on Opus 5.5 versus $3.50 on Opus 5, and cache hits plus effort move that bill more than the list-price cut.
