OpenAI Agents SDK: Sandboxing and Native Harnesses

• Native sandboxing as first-class primitive (default controlled execution).
• Model-native harness: keeps planning, tool selection, self-correction inside model reasoning chain.
• Configurable memory, file/tool workflow primitives.

Anthropic Claude Opus 4.7

• CursorBench 70% (vs Opus 4.6 at 58%)
• Notion Agent evals: +14% over Opus 4.6 at fewer tokens and a third of the tool errors
• 93-task internal coding benchmark: 13% improvement

Claude Code v2.1.126

• Gateway model picker from /v1/models
• claude project purge
• OAuth login for WSL2/SSH/containers
• Security fix: allowManagedDomainsOnly / allowManagedReadPathsOnly
• Agent SDK parallel tool call fix

Strategic Inflection Points

1. Sandboxing is non-negotiable
2. Model-native controls replacing framework loops (MCP, gateway logic)
3. Pricing pressure intensifying: cost-per-task dropping
