Tier A: Strong with clear operating rules.
Claude Sonnet 4.6
Fast workhorse with much of Opus quality.
Our take
Sonnet 4.6 is not as intelligent as the top A-tier models, but it is fast, cheaper, follows instructions, and is the daily model many vibe coders use.
Best for
- Day-to-day coding
- Follow-up edits
- Lower-cost Claude workflows
- Instruction-following tasks
Watch out
- Not ideal for the hardest architecture work
- Use Opus for heavy lifting when stakes rise
Why it is ranked here
- The video estimates it gives much of Opus code quality at a lower price.
- It is described as fast and instruction-following.
- It belongs near the end of A tier because capability is lower than Opus, but value is high.
