Opus 4.7 is the next generation of Anthropic's Opus family, built for long-running, asynchronous agents. Building on the coding and agentic strengths of Opus 4.6, it delivers stronger performance on...
Best coding model APIs for agents and code review
Compare coding-oriented model APIs by context length, tool support, JSON output, latency estimate, price, and recommended production role.
Coding model selection depends on repository size, tool-calling needs, instruction reliability, and the cost of long output. A coding assistant that reads a large codebase needs different economics from a short code-completion feature. NextModel highlights coding candidates with context length, tool support, price, and best-use guidance so teams can choose a primary model and a fallback policy.
Source basis: NextModel use-case taxonomy and OpenRouter supported-parameter metadata when available.

FAQ
Coding models FAQ
What makes a model good for coding agents?
Long context, reliable tool calling, structured output, and stable instruction following matter more than raw token price alone.
How should teams control coding-agent cost?
Use budget policies, compare output-heavy token cost, and route simple tasks to lower-cost models before escalating difficult tasks.
