Anthropic
Weighted capability + reliability + privacy. Anthropic Sonnet/Opus lead agentic reasoning; OpenAI closest peer; Gemini for value/multimodal.
Pricing (directional): Sonnet 5 ~$2/$10 per 1M; Opus ~$5/$25; Haiku 4.5 ~$1/$5; Fable higher. Prompt caching + batch. Managed Agents session-hour fees. US-only inference ~1.1x.
Lock-in risk: higher = more lock-in (worse). Overall already inverts this dimension.
Depot default for serious coding and production agents. Prefer Sonnet for cost/quality; reserve Opus for hard reasoning. Pair with Bedrock/Vertex if procurement demands cloud wrappers.
