Claude Opus 4.6 and Claude Sonnet 4.6 are the two models in Anthropic's current flagship family. If you're running OpenClaw and paying out of pocket for API access, the choice between them has real dollar consequences — and the right answer depends almost entirely on what kind of tasks you're running.
This is what I've found after routing a few weeks of real OpenClaw workloads through both.
The pricing gap is large
Opus 4.6 costs roughly 15x more per token than Sonnet 4.6. On a typical OpenClaw session with 200k-500k tokens, that difference adds up fast:
- A session that costs ~$0.80 with Sonnet 4.6 costs ~$12 with Opus 4.6
- At daily usage of 3-4 sessions, that's $2.40/day vs $36/day
- Monthly: $72 vs $1,080
Most developers aren't running all-Opus, but many don't realize how much of their token spend is going to tasks where Opus's extra capability is irrelevant.
Where Opus 4.6 actually earns its price
Opus wins decisively on tasks that require sustained multi-step reasoning:
- Complex architectural decisions where getting it wrong is expensive
- Long-context code review where relationships between distant parts matter
- Novel problem solving where Sonnet tends to fall back to pattern-matching
- Tasks requiring careful judgment about edge cases (security reviews, data model design)
On these tasks, the quality difference is real and meaningful. Sonnet will often produce plausible-looking answers that miss something subtle. Opus is more likely to catch it.
Where Opus 4.6 doesn't earn it
The majority of an OpenClaw session is not complex reasoning. It's:
- File reads and searches (grep, glob, find)
- Reformatting, summarizing, renaming
- Boilerplate code generation
- Simple Q&A about what a function does
- Running and interpreting test output
- Short CRUD operations
For all of these, Sonnet 4.6 is indistinguishable from Opus in practice. So is DeepSeek V3, which costs even less. The extra intelligence that Opus provides simply doesn't apply.
The trap many developers fall into: they set their OpenClaw config to Opus and leave it there, because the hard tasks feel better. Then they pay Opus prices for every file read in the session.
The routing approach
The practical solution is per-task routing: use Opus for the reasoning-heavy phases, Sonnet or cheaper models for the mechanical work.
This is what smart routing in OpenClaw looks like in practice:
# In your CLAUDE.md or session config:
# Use teamo-best for architectural decisions, code review, complex debugging
# Use teamo-eco for file operations, grep, summarization, simple completions
With TeamoRouter installed as an OpenClaw skill (2-second setup), you can define this routing explicitly or let the routing presets handle it automatically. The teamo-balanced preset routes to Sonnet 4.6 for most tasks, escalates to Opus for the requests that actually need it.
Install takes 90 seconds:

Real numbers from a week of routing
Rough breakdown of a typical OpenClaw session by task type and where intelligence actually helps:
| Task type | Share of tokens | Opus advantage | Recommended model |
|---|---|---|---|
| File reads/grep | 30-40% | None | Sonnet 4.6 or DeepSeek V3 |
| Code editing (boilerplate) | 15-20% | Minimal | Sonnet 4.6 |
| Code review (complex) | 10-15% | High | Opus 4.6 |
| Architecture decisions | 5-10% | Very high | Opus 4.6 |
| Test interpretation | 10-15% | None | Sonnet 4.6 |
| Simple Q&A | 10-15% | None | DeepSeek V3 |
Rough result: about 20-25% of your token spend actually benefits from Opus. The rest is paying Opus prices for Sonnet-tier work.
What this means practically
If you're on direct Anthropic API billing, smart model routing can cut your monthly OpenClaw costs by 50-70% without affecting the quality of output on the tasks that matter.
If you're on Claude Max plan (5x or 20x), routing mechanical tasks to cheaper providers via TeamoRouter means your daily Claude quota gets spent on the 20-25% of tasks where Claude's quality is irreplaceable — and you stop hitting limits mid-session.
The March 23 quota regression that's been hitting Max plan users makes this especially relevant right now: the quota is tighter, so how you spend it matters more.
FAQ
Is Opus 4.6 meaningfully better than Opus 3 Opus for OpenClaw workflows?
For most agentic tasks, the difference is incremental. The larger gain comes from routing correctly — spending Opus-tier tokens on Opus-tier work — than from upgrading within the Opus family.
Does TeamoRouter support both Opus 4.6 and Sonnet 4.6?
Yes, both models are available. You can specify them directly (claude-opus-4-6, claude-sonnet-4-6) or use the routing presets which select the current best model automatically.
What about Claude Haiku for cheap tasks?
Haiku 4.5 is available and works well for very simple completions. DeepSeek V3 is often a better value at similar or lower cost with stronger capability, but Haiku is worth testing for your specific workload.
Will the pricing change as the models mature?
Anthropic historically reduces prices as model efficiency improves. The routing strategy remains useful regardless — route smarter, spend less, keep quality where it matters.
