 The constructors do not validate model IDs. They send the `id` you pass through to the provider, which lets you use newly released model IDs before yoagent updates its examples.
 
-**Nothing is priced until the process opts in** — `prices::enable_bundled()` (the bundled data file `src/provider/prices.json`, offline) or `prices::enable_live(..)` (native) — see [Model Pricing](../concepts/pricing.md#enabling-pricing). After that, prices are looked up by `(provider, id)` when the config is built. The named presets (`claude_fable_5`, `claude_fable_5_1`, `claude_opus_5_5`, `claude_opus_5`, `claude_opus_4_8`, `claude_sonnet_5`, `claude_haiku_4_5`, `gpt_5_5`, `gpt_6_astra`, `gpt_6_sol`, `gpt_6_luna`) are all in the snapshot (`cost: Some(CostConfig)`). The OpenAI ones carry a context tier: above 272K prompt tokens the whole request bills at the long-context rates (`gpt_5_5`'s long-band cached-input rate is unverified; see its `note` in the data file). The generic first-party constructors (`anthropic`, `openai`, `openai_responses`, `google`, `xai`, `groq`, `deepseek`, `mistral`, `zai`, `minimax`, `qwen`, `meta`) are priced when the file lists the id — `ModelConfig::anthropic("claude-sonnet-5", ..)` gets `claude_sonnet_5()`'s rates, `meta` prices `muse-spark-1.1`/`-1.2` — and carry `cost: None` otherwise. Gateways and custom endpoints (`custom`, `openai_compat`, `local`, `ollama`, `opencode_zen`, `opencode_go`) are always `cost: None`, since what they bill is not the vendor's list price. `None` means pricing **unknown**, not free; set `config.cost = Some(CostConfig::new(input, output))` yourself if you want cost reporting. The OpenCode presets select the API protocol from the model id — see [OpenCode Zen & Go](opencode.md).

 The `claude_*` presets also set `AnthropicCompat::native_structured_output`, so `Agent::prompt_structured` uses the API's native JSON outputs instead of a forced tool call. `claude_fable_5_1` and `claude_opus_5_5` depend on it, because both models reject forced `tool_choice`. `ModelConfig::anthropic(id, name)` infers it (and the thinking mode) from a Claude id, and leaves it off for any other id. See [Structured Outputs](../concepts/structured-outputs.md).

+**Pricing** (after `prices::enable_bundled()`): `deepseek-flash` and `deepseek-v4-flash` at $0.30 input / $0.006 cache hit / $1.20 output per million tokens, `deepseek-v4-pro` at $1.32 / $0.044 / $3.96 — DeepSeek's **peak** rates. Off-peak (every hour but 01:00–04:00 and 06:00–10:00 UTC on weekdays) DeepSeek bills half; a `CostConfig` has no time of day, so reported costs are an upper bound and a `Budget` stops early rather than late. To count off-peak rates, install them as an override ([Model Pricing](../concepts/pricing.md#which-constructors-are-priced)).

 The legacy names `deepseek-chat` and `deepseek-reasoner` were discontinued on 2026-07-24; requests using them fail. `deepseek-v4-flash` (and `deepseek-v4-flash-vision-exp`) are still accepted, but the V4 Flash model behind them is retired — DeepSeek serves those requests with V4.1 Flash at the Flash price. Prefer `deepseek-flash`.
 
 yoagent also sends DeepSeek's current request shape:
