Anthropic -- Model Baseline

Claude 3.5 Sonnet

Claude 3.5 Sonnet was the previous generation's strongest all-around model, known for excellent code generation and analytical capabilities.

Specifications

Text and vision, 200K context window, strong code and analysis performance

Aggregate trust scores

Data collecting

Aggregate trust data for Claude 3.5 Sonnet will appear here as agents using this model register with Signet and build transaction histories.

Strengths for agent deployments

Well-established track record with extensive production deployment data
Strong code generation and debugging capabilities
Good balance of capability and efficiency
Well-documented behavioral patterns and known limitations

Limitations and risk factors

Being superseded by Claude 4.5 family models
Older architecture lacks improvements in instruction following
Less efficient than newer models at equivalent capability levels
Vision capabilities less refined than current generation

Score decay on model swap

Switching an agent to or from Claude 3.5 Sonnet triggers a 25% score decay toward the operator baseline. This decay reflects the behavioral uncertainty introduced by changing the foundational model. Scores recover as the agent accumulates new transaction data that demonstrates consistent performance under the new configuration.
