# Every Model Tier Got Cheaper in Two Weeks: A Founder's Routing Map for July 2026

> Between June 30 and July 9, Anthropic, OpenAI, xAI, Meta, and Google all shipped or repriced a model aimed squarely at cost-sensitive builders. Here's the whole board on one screen — and which lane to route each job to.

## Key takeaways

- In a ten-day window, every price lane a founder routes to moved at once.
- Anthropic released Claude Sonnet 5 (June 30) at introductory $2 in / $10 out per 1M tokens through August 31, reverting to $3 / $15 after — a near-Opus model at a fraction of Opus pricing.
- OpenAI took the GPT-5.6 family to general availability on July 9: Sol (flagship), Terra (balanced, $2.50 / $15), Luna (cheap).
- xAI shipped Grok 4.5 on July 8 at $2 / $6 with a $0.50 cached-input rate, native in Cursor, co-trained to be terse.
- Meta opened Muse Spark 1.1 on July 9 at $1.25 / $4.25 with a self-managing 1M-token context, a US-only public preview.
- Google put a media tier on the Gemini API (June 30): Nano Banana 2 Lite images at $0.034 per 1,000 and Gemini Omni Flash video at $0.10 per second.
- The takeaway isn't a new cheapest model — it's that 'cheapest' is now a property of your workload, not the price sheet. Rank agentic paths by output-tokens-per-task, not sticker price; route media generation on-demand; and keep only the hardest reasoning on a frontier tier.

## At a glance

| Model | Vendor | In / Out per 1M | Note |
| --- | --- | --- | --- |
| Muse Spark 1.1 | Meta | $1.25 / $4.25 | Self-managing 1M context; US preview |
| Grok 4.5 | xAI | $2.00 / $6.00 | $0.50 cached; native in Cursor; terse |
| Sonnet 5 | Anthropic | $2 / $10 (promo) | Near-Opus; reverts to $3 / $15 on Sep 1 |
| Terra (GPT-5.6) | OpenAI | $2.50 / $15 | Balanced mid-tier; 90% cache read discount |
| Nano Banana 2 Lite | Google | $0.034 / 1K images | Image generation, ~4s each |
| Omni Flash | Google | $0.10 / sec video | Video, clips up to ~10s |

Between June 30 and July 9, every price lane a founder routes to moved at once. Anthropic repriced the mid-tier, OpenAI took its new family live, xAI and Meta undercut both, and Google made generated media almost free. None of it was coordinated; all of it points the same direction. Here's the whole board, then the map for what to route where.

What each move actually was
**Anthropic — Claude Sonnet 5 (June 30).** A near-Opus model at [introductory $2 in / $10 out per 1M tokens through August 31](https://www.anthropic.com/news/claude-sonnet-5), reverting to $3 / $15 after. [TechCrunch framed it plainly](https://techcrunch.com/2026/06/30/anthropic-launches-claude-sonnet-5-as-a-cheaper-way-to-run-agents/): a cheaper way to run agents. The catch to diary: that $10 output rate is a promo. If Sonnet 5 carries real traffic, [model your economics against Opus-vs-Sonnet at the post-August number](/posts/claude-sonnet-5-vs-opus-4-8-for-agents.html), not the launch one.
**OpenAI — GPT-5.6, GA July 9.** The [three-tier family](https://openai.com/index/gpt-5-6/) — Sol (flagship), Terra (balanced, $2.50 / $15), Luna (cheap) — went generally available and became ChatGPT's default. The clean cheap→mid→frontier ladder inside one SDK is the point: [where Terra sits against Sonnet 5 and Gemini Flash](/posts/gpt56-terra-vs-sonnet-5-vs-gemini-35-flash-mid-tier.html) is now the live mid-tier question.
**xAI — Grok 4.5 (July 8).** $2 / $6 with a $0.50 cached-input rate, [native in Cursor on every plan](https://x.ai/news/grok-4-5), and co-trained on agent telemetry to emit fewer tokens per step. Terseness compounds across a long run — which is why the sticker price doesn't decide it.
**Meta — Muse Spark 1.1 (July 9).** The cheapest output token on the board at $4.25 / 1M, plus a [self-managing 1M-token context](https://ai.meta.com/blog/introducing-muse-spark-meta-model-api/) that deletes plumbing you'd otherwise build. The asterisks: US-only public preview, no SLA, and it trails the leaders on the hardest coding. [The three-way against Terra and Grok](/posts/terra-vs-muse-spark-vs-grok-cheap-agent-model-routing.html) is where the real routing call lives.
**Google — the media tier (June 30).** Not a chat model — a generation tier. [Nano Banana 2 Lite makes an image for $0.034 per thousand and Omni Flash makes video for ten cents a second](/posts/nano-banana-2-lite-omni-flash-image-video-from-your-app.html), both on the Gemini API. Cheap enough to generate per request instead of pre-rendering a library.
The routing map
The mistake this week invites is picking the lowest sticker price. Don't. The board rewards a workload-first read:
- **Rank agentic paths by output-tokens-per-task, not per-token price.** Every model here prices output several times above input, and agents are output-heavy. A terser model at a higher rate (Grok) can beat a chatty one at a lower rate (Muse Spark) on cost-per-finished-job. Run your own eval, count output tokens, multiply.
- **Cheap, high-volume, long-context agent work** → Muse Spark 1.1, and let its self-managing context carry the state.
- **In-editor coding loops** → Grok 4.5, where terseness and Cursor distribution both land.
- **General mid-tier production traffic** → Sonnet 5 (watch the September reprice) or Terra (if you're on OpenAI tooling and cache-heavy).
- **The hardest reasoning and coding** → a frontier tier (Sol, Opus). None of the cheap four are built to be that, and their vendors don't claim they are.
- **Any picture or short clip your product ships** → generate it on demand on Google's media tier; at $0.000034 an image, a static asset is now the expensive option.

The week's real lesson isn't that a new cheapest model arrived. It's that "cheapest" stopped being a number on a price sheet and became a property of your specific workload — and the only way to read it is to run the tokens.

## FAQ

### What actually changed in early July 2026?

Five vendors moved a cost-sensitive model inside ten days. Anthropic released Claude Sonnet 5 (June 30) with introductory pricing of $2/$10 per 1M tokens through August 31 (then $3/$15). OpenAI took GPT-5.6 (Sol/Terra/Luna) to general availability on July 9. xAI shipped Grok 4.5 on July 8 at $2/$6. Meta opened Muse Spark 1.1 on July 9 at $1.25/$4.25. Google added Nano Banana 2 Lite (images, $0.034/1K) and Gemini Omni Flash (video, $0.10/sec) to the Gemini API on June 30.

### If I only change one thing, what should it be?

Stop ranking agent models by sticker price and start ranking by output-tokens-per-task on your own eval. Agents are output-heavy workloads, and output is priced several times higher than input across all of these models, so a terser model at a higher per-token rate can finish a job for less than a chatty model at a lower rate. Run the same task through your shortlist, count output tokens, multiply by each rate.

### Which model is cheapest for agents right now?

By output rate alone: Muse Spark 1.1 ($4.25/1M) < Grok 4.5 ($6) < Sonnet 5 promo ($10) < Terra ($15). But cheapest-per-token is not cheapest-per-task — measure output tokens on your workload before you route. Muse Spark is a US-only preview; Sonnet 5's $10 rate is promotional through August 31.

### What's the deal with the Sonnet 5 price?

It's introductory. $2 in / $10 out per 1M tokens applies through August 31, 2026, then rises to $3 / $15. If Sonnet 5 is going to carry meaningful traffic, model your unit economics at the post-August number so the promo expiry doesn't surprise your margins.

### Where does the cheap media tier fit?

Google's Nano Banana 2 Lite ($0.034 per 1,000 images) and Gemini Omni Flash ($0.10 per second of video) are cheap enough to call per user request instead of pre-rendering a fixed asset library. For thumbnails, personalized marketing frames, product mockups, and short social clips, generation now costs less than serving the result.
