The Short Version
On April 16, 2026, Anthropic shipped Claude Opus 4.7 β the newest member of the Claude 4 family. It is a straight upgrade over Opus 4.6 on the dimensions that matter for autonomous agents: long-horizon reasoning, software engineering, and high-resolution vision.
For TeamDay users, the headline is simple: every agent on the roster can run Opus 4.7 today, at the same price as 4.6, with a 1M token context window included.

What Anthropic Claims
Anthropic's headline numbers from the launch:
- +13% on coding benchmarks vs Opus 4.6
- ~3x more production tasks resolved on long-running engineering work
- High-resolution vision up to 3.75 megapixels (vs 1.15 MP previously)
- Verifies its own outputs before reporting back β fewer "I'm done" moments that aren't actually done
The "verify before reporting" behavior is the one we noticed first. On TeamDay missions where 4.6 would occasionally claim completion despite a failing test, 4.7 now re-runs the test and either fixes the issue or returns a clear blocker.
How It Compares
A rough placement against the rest of the April 2026 frontier lineup:
| Model | Released | Strength | Context | Pricing (in/out per 1M) |
|---|---|---|---|---|
| Claude Opus 4.7 | Apr 16, 2026 | Long-horizon coding, verification | 1M | $5 / $25 |
| GPT-5.5 | Apr 23, 2026 | Multimodal unified, agentic computer use | 400K | $2.50 / $20 |
| Claude Sonnet 4.6 | Feb 17, 2026 | Near-Opus quality at 1/5 cost | 1M | $3 / $15 |
| Gemini 3.1 Pro | Feb 19, 2026 | ARC-AGI-2 reasoning | 2M | $2 / $10 |
Opus 4.7 is not the cheapest option. It is the one we reach for when the mission cost of being wrong is high β security review, schema migrations, customer-facing copy, anything where "looks done" must equal "is done."
How to Use Opus 4.7 in TeamDay
How it's wired
Opus 4.7 reaches your TeamDay agents through the Claude Code harness β Anthropic's official agentic runtime. When you select Claude Code as an agent's harness, every model in the Claude family becomes available β including 4.7 the day Anthropic ships it. No connector update on our side, no waiting for an "integration release." The harness is the integration.
1. Switch a single agent
Open any agent in your roster, click Agent Settings β Harness β Claude Code, then Model β Claude Opus 4.7. The next mission this agent runs will use the new model. No redeploy, no migration step.
2. Set it as the workspace default
Workspace owners can set Opus 4.7 as the default for new agents under Workspace Settings β Defaults β Reasoning model. Existing agents keep whatever they were configured with.
3. Pair it with a cheaper model β or another harness
A pattern we like: route the planning step of a long mission to Opus 4.7, then delegate execution sub-tasks to Sonnet 4.6 or to a Codex agent running GPT-5.5. You get Opus-quality decomposition at roughly 1/3 the cost. Configure this in Mission Templates β Step Models.
4. Bring your own key
If you already have an Anthropic, Bedrock, or Vertex contract, wire the key in Workspace Settings β API Keys. TeamDay uses your key for all Opus 4.7 calls and never proxies through ours.
When Not to Reach for Opus 4.7
- High-volume, low-stakes loops β Sonnet 4.6 is 5x cheaper and indistinguishable on most content workflows.
- Pure image or video generation β pair Opus 4.7 as the planner with Seedance 2.0 or gpt-image-2 as the executor.
- Sub-second latency requirements β Opus 4.7 is the deepest thinker in the lineup, not the fastest.
TL;DR
Opus 4.7 is the new default for missions where you need an agent to think hard, work long, and verify its own work before claiming success. It's live on every TeamDay agent today. Switch one agent over, run a mission, see the difference.
