Revalidate thresholds set on v1.1. The v1.2 card says it gives different answers to v1.1-style requests.\n4. Group questions that are facets of one decision. Send independent candidates, such as documents or tools, in separate requests.\n5. Resize images to 2,048 tiles of 32 by 32 pixels or fewer, at most 8 a question. Larger images end in a 504 after about a minute.\n6. For the weights, use the repository's `pplx_decider` package.

The FLAC, MP3, OGG and MP4 audio named on the blog are refused with media_unsupported.\n2. Keep state under 38,000 tokens. Long-context requests return 404 long_context_not_available, which never succeeds on retry.\n3. Reuse the same Idempotency-Key and body on retries, and stop when error.retryable or x-should-retry is false.\n4. Check every entry in answers even on HTTP 200, since one question can be refused while the others are answered.\n5. Treat probabilities as uncalibrated while calibrated is false, and pin system-zero-2.0.0 when answers must not move with the alias.\n\n## Tutorials\n\n- [Find defect reports with Perplexity Decisions](https://www.anchorterminal.com/tutorials/pplx-decider/), for pplx-decider\n\n## Questions\n\n### Which is better for AI agents, pplx-decider or RightNow System Zero?\n\npplx-decider scores 68.1 (B) on agent readiness against RightNow System Zero's 66.8 (B), and leads in 3 of 7 scored categories.
