# The Founder's Wire, Week of July 14: GPT-5.6 Goes Fully GA, China's Persona Law Lands, and the Model Bill Keeps Falling

> Four verified moves that change what a solo founder ships this week: confirmed three-tier GPT-5.6 pricing, tomorrow's Doubao and Qwen agent shutdown, Sonnet 5 as the new default, and a cheaper tool-schema bill.

## Key takeaways

- GPT-5.6 finished its rollout: as of July 9 it is generally available across ChatGPT, Codex, and the API in three tiers — Sol ($5/$30), Terra ($2.50/$15), and Luna ($1/$6) per million tokens. Terra ties Claude Fable 5 at 84.3% on Terminal-Bench 2.1 for half of Sol's price, so 'default to Terra' is now the honest routing rule.
- China's Interim Measures for AI Anthropomorphic Interactive Services take effect July 15. ByteDance's Doubao and Alibaba's Qwen are shutting down their consumer custom-agent features; Doubao gives read-only access until October 15 and points users to a separate app, while Qwen has announced permanent deletion with no migration path.
- Claude Sonnet 5 (June 30) is the new claude.ai default at an introductory $2/$10 through August 31, delivering near-Opus agentic performance at Sonnet pricing.
- Microsoft Agent Framework 1.11 shipped progressive MCP tool discovery — agents load and unload tool schemas mid-run, cutting the context tax of a large tool catalog.

## At a glance

| Model | Input $/M | Output $/M | Terminal-Bench 2.1 | Route it to |
| --- | --- | --- | --- | --- |
| GPT-5.6 Terra | $2.50 | $15 | 84.3% | Your everyday agent loop |
| GPT-5.6 Sol | $5 | $30 | 88.8% | Hardest planning + coding runs |
| GPT-5.6 Luna | $1 | $6 | 82.5% | High-volume, latency-sensitive calls |
| Claude Sonnet 5 | $2 (intro) | $10 (intro) | 80.4% | Agentic multi-step at Sonnet price |

Four things moved this week that a solo founder should actually price into what they ship — and one throughline they add up to. All verified, all sourced, each with the one line that matters for a team of one.
1. GPT-5.6 is fully GA — the three-tier menu is set
OpenAI finished the GPT-5.6 rollout on **July 9**. It's now generally available across ChatGPT, Codex, and the API, and the pricing is confirmed, not rumored. Per million tokens: **Sol $5 in / $30 out, Terra $2.50 / $15, Luna $1 / $6.** The three names are what OpenAI calls "durable capability tiers" — each can advance on its own cadence, so you're routing to a tier, not a version number.
The benchmark that decides your bill is Terminal-Bench 2.1: **Terra ties Claude Fable 5 at 84.3%**, while Sol scores 88.8% and Luna 82.5%. Terra sits within two to three points of Sol on most [agent evals](/topics/agent-evals) at half the price.
**What it means:** "Default to Terra" is now the honest rule. Route your everyday agent loop to Terra, reserve Sol for the hardest planning-and-coding runs, and push high-volume, latency-sensitive calls to Luna. If you hard-coded a model string during the government-gated preview, this is the week to swap it for a tier and re-check your per-task cost. We broke the three tiers down in [Sol vs Terra vs Luna](/posts/gpt-5-6-sol-vs-terra-vs-luna.html), and put Terra head-to-head with the cheap [open models](/topics/model-selection) in [which cheap agent model to route to](/posts/terra-vs-muse-spark-vs-grok-cheap-agent-model-routing.html).
2. China's persona law lands July 15 — Doubao and Qwen pull their agents
The **Interim Measures for the Administration of AI Anthropomorphic Interactive Services** — co-issued in April by the Cyberspace Administration of China and four partner agencies — take effect **tomorrow, July 15.** Neither ByteDance's Doubao nor Alibaba's Qwen could get their consumer custom-agent architecture compliant in time, so both are shutting those features down.
The data handling diverges sharply. **Doubao** gives users read-only access to their agent configs and chat histories until **October 15**, then processes the data per its privacy policy — and redirects them to Maoxiang, a separate ByteDance app built for compliance. **Qwen** has announced **permanent deletion** with no grace period and no migration path.
**What it means:** This is a portability fire drill you should run on your own stack today. If a platform can delete your users' [agent memory](/topics/agent-memory) on a regulator's timeline, "the model owns the memory" is a liability, not a feature. Export paths and user-owned memory stores stop being nice-to-haves the moment a jurisdiction you sell into writes a rule. We covered the shutdown mechanics in [the Doubao and Qwen agent shutdown](/posts/china-ai-companion-law-doubao-qwen-agent-shutdown.html) and the founder checklist in [what founders should do now that it's in effect](/posts/china-ai-companion-law-in-effect-what-founders-do.html).
3. Claude Sonnet 5 is the new default — near-Opus at Sonnet price
Anthropic shipped **Claude Sonnet 5 on June 30** and made it the default for every Free and Pro user on claude.ai the same day. It posts **63.2% on SWE-bench Pro** and **80.4% on Terminal-Bench 2.1** — the latter actually beating Opus 4.8's 74.6% — and it's priced at an introductory **$2 / $10** through August 31 before moving to $3 / $15.
**What it means:** Between Sonnet 5 and GPT-5.6 Terra, the mid-tier is where the frontier moved this quarter. If your agent's default model is still a flagship from Q1, you're paying a premium for capability your task no longer needs. Re-benchmark your own workload against both mid-tiers before the introductory windows close — we ran the numbers for a bootstrapped stack in [Sonnet 5: cheaper agents for founders](/posts/claude-sonnet-5-cheaper-agents-for-founders.html).
4. Microsoft Agent Framework 1.11 — your tool catalog stops taxing every turn
Microsoft [Agent Framework](/topics/agent-frameworks) shipped **1.11**, and the headline for anyone running a large tool set is **progressive MCP tool discovery**: agents can now discover, load, and *unload* MCP tool schemas on demand within a single run, while the `allowed_tools` boundary stays intact. Tools can be added or removed based on prior tool results, mid-run.
**What it means:** Every tool schema you expose is tokens the model re-reads on every turn. Progressive disclosure lets you register a hundred tools and only pay for the handful in play right now — the same lever that makes big MCP catalogs affordable instead of context-bloating. If your agent's system prompt is fat with tool definitions, this is the pattern to copy even if you're not on MAF. We walked through the framework's implementation in [progressive MCP disclosure](/posts/microsoft-agent-framework-progressive-mcp-disclosure.html), and the complementary token-saver in [how to cache your agent's tool definitions](/posts/how-to-cache-agent-tool-definitions-cut-token-cost.html).
5. The quieter throughline: the model price war is now the founder's advantage
Three of this week's five items are prices falling. Terra at $2.50 input ties a frontier coding model from three months ago. Sonnet 5 undercuts its own predecessor. The tool-schema tax is getting engineered away. For a bootstrapped builder, the compounding effect is that the cost of a capable agent keeps dropping *while you sleep* — which means the discipline that pays is re-pricing your stack every few weeks, not picking one model and forgetting it.
**Do this before Friday:** swap any hard-coded model string for a routing tier, run one real task through Terra and Sonnet 5 side by side, and add an export path to wherever your agents keep memory. Three small moves; all three got cheaper or more urgent this week.

## FAQ

### Is GPT-5.6 generally available now?

Yes. OpenAI completed the GPT-5.6 rollout on July 9, 2026; it is generally available across ChatGPT, Codex, and the API. It ships in three tiers — Sol, Terra, and Luna — priced per million tokens at $5/$30, $2.50/$15, and $1/$6 respectively.

### Which GPT-5.6 tier should a founder default to?

Terra. It ties Claude Fable 5 at 84.3% on Terminal-Bench 2.1 and stays within two to three points of Sol on most agent benchmarks at half the price, so the cost difference dominates. Reserve Sol for the hardest planning and coding runs; route high-volume, latency-sensitive calls to Luna.

### What happens to Doubao and Qwen agents on July 15?

China's AI anthropomorphic-services rules take effect July 15, 2026, and both platforms are disabling consumer custom agents. Doubao (ByteDance) gives users read-only access to their agent configs and chat history until October 15, then processes the data per its privacy policy; Qwen (Alibaba) has announced permanent deletion with no announced migration path.
