Strengths & weaknesses

Strengths

  • 0.44s time to first audio, which Deepslate cites from AA
  • 27 languages with EU or on-premises hosting
  • Function tools and webhooks for live lookups

Weaknesses

  • Big Bench Audio 85.0% (AA)
  • No published release date; v3.0 is a preview that requires access approval

Not notable: #23 on AA Big Bench Audio (85.0%). No release date on Deepslate's site or docs. The docs list opal-v2.1 (GA, platform default) and opal-v3.0-preview (on request). Price is the regular rate; a release offer of 2 ct/min was running. Deepslate's own page says the reasoning core is based on an open-weights LLM.
