Claude 4.5 Haiku

Four agent perspectives converged on a synthesized plan:

  1. 01Risks the skeptic flagged with mitigations
  2. 02Structured milestones from the analyst
  3. 03Creative distribution angles worth testing
  4. 04Pragmatic 30-day sequence to ship

Beyond a single completion

One Claude pass hides blind spots

A single Sonnet or Opus answer can be excellent—and still miss an angle you would catch in a review meeting.

  1. 01

    One perspective

    A single model pass optimizes for one coherent answer—not four independent reviews.

  2. 02

    Hidden assumptions

    Without a skeptic or pragmatist lane, risky assumptions survive until production.

  3. 03

    Manual re-prompting

    Asking the same model repeatedly in new chats loses shared context and costs time.

FAQ

Claude 4.5 Haiku Ultra questions

Can I run Ultra Mode with Claude 4.5 Haiku?

Yes. Select Claude 4.5 Haiku in the workspace, choose Ultra Mode (Pro or Lifetime), and pick 2–4 parallel agents. Each turn uses your normal request allowance (e.g. 4 requests for 3 agents including synthesis).

How is this different from asking the same model twice?

Agents receive role-specific system instructions (Skeptic, Analyst, Creative, Pragmatist) and run in parallel before a dedicated synthesis step merges their perspectives.

Can I read what each agent said?

Yes. After the response completes, expand Agent discussion on the message to inspect each perspective.

How much does milkyway.chat cost?

Pro is $14.99 per month and includes all premium models plus voice chat. Lifetime is $149.99 as a one-time payment and lets you bring your own API keys. Visit the pricing page for current plan details.
