Lyria 3 Pro Preview or o3: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Lyria 3 Pro Preview for a larger context window (1.05M against 200K tokens).
No benchmark has tested both yet. Lyria 3 Pro Preview has none yet; o3 on Aider polyglot, SWE-bench Verified and SWE-bench Multimodal. Compare them on price and context instead.
