"""
Build the MWP model chronicle: a few aired scripts per script-writer model (PLAN-040).
Publishes https://huggingface.co/datasets/My-Weird-Prompts/model-chronicle (public)
and writes website/public/data/model-chronicle.json (the same rows minus
`transcript`) for the /benchmark hub.
Selection, per canonical writer model (canonicalisation mirrors
`canonical_model()` in pipeline/scripts/build_transcript_corpus.py, i.e. the
`llm_model_canonical` column of the HF `transcripts` dataset):
  * Candidates: aired (`is_test = false`), English, with a transcript, and not a
    translation or an `audio_eval` special. Records that name no model are
    skipped: manual-script, manual-generation, unknown, none, openrouter/mixed,
    null/empty.
  * Pool, first non-empty of: pipeline-written with >= 1,500 words; pipeline-
    written of any length; offline-written (episode_type = 'manual-script',
    i.e. Claude Code via /webhook/generate-from-script) >= 1,500 words; offline
    of any length. So offline scripts appear only when a model has nothing else.
  * Picks from the pool, ordered by pub_date: earliest, the median-date one
    (index (n-1)//2) and the latest; fewer when the pool has fewer than 3.
Deterministic: the same database gives the same picks.
Usage:
    .venv/bin/python scripts/build_model_chronicle.py              # build + push
    .venv/bin/python scripts/build_model_chronicle.py --dry-run    # build only, no push
    .venv/bin/python scripts/build_model_chronicle.py --out DIR    # where the jsonl + card go
Reads POSTGRES_URL and HF_TOKEN from the environment or .env.production (the same
mechanism as pipeline/scripts/sync_hf_dataset.py). Read-only on the database.

# My Weird Prompts — Model Chronicle
*My Weird Prompts* is an AI-generated podcast: every episode's dialogue is written by
a large language model, and the model that writes it has changed many times since
November 2025. The back catalogue is therefore a chronicle of how frontier models
evolved, with each era's writer on air. This dataset is a small, curated slice of it —
**up to three aired scripts per writer model** — so anyone can read eras side by side
("Gemini 2.5 Flash vs DeepSeek V4 Pro vs GPT-6.1 Sol") without downloading the full
corpus.
{len(rows)} scripts from {n_models} writer models, built {built_at}.
- Site hub, with the leaderboard and writer history: <https://myweirdprompts.com/benchmark>
- Full corpus (every episode, turns, text statistics): [`My-Weird-Prompts/transcripts`](https://huggingface.co/datasets/My-Weird-Prompts/transcripts)
- Browse and filter every transcript by model: [`My-Weird-Prompts/transcripts-explorer`](https://huggingface.co/spaces/My-Weird-Prompts/transcripts-explorer)
- Controlled, same-prompt benchmark of candidate writers: <https://github.com/My-Weird-Prompts/eval>
## Read this before comparing
**These are not same-prompt comparisons.** Each script answers whatever listener or
host prompt was on the queue that day; topics, lengths and episode formats differ.
For like-for-like scoring of writers on identical briefs, use the eval repo above.
The model is not the only thing that changed between eras:
- **The system-prompt template changed with the model, twice.** In the full
  catalogue (measured 2026-09-22 over 5,332 episodes), template 3.5 → 4.0 landed on
  the April 2026 Gemini → DeepSeek switch, and 4.0 → 4.1 on the September 2026
  DeepSeek V4 Pro → V4.1 Flash switch. A difference between those eras is never
  attributable to the model alone. `prompt_version` is included per row; null
  means not recorded (before March 2026), not "none".
- **A deterministic verbal-tic cleanup pass** runs after generation and deletes
  stock phrasings (conjunction openers, sycophantic openers, echo handoffs), so
  the aired text is not the raw model output. The full corpus counts what it removed
  per episode (`tic_*` columns).
- **Episode length moved**: median length rose from about 3,000 words (2025) to
  about 4,200 (2026), so length-sensitive measures (n-gram repetition, compression)
  trend partly with length.
- **Some eras are a few days long.** The March 2026 and October 2026 bake-offs aired
  one to a handful of episodes per candidate; those share that week's prompts, so
  anything topic-linked in them is subject matter, not style. `model_episode_count`
  shows how much each model actually wrote.
- **Offline scripts** (`written = offline`, {n_offline} rows here) were written in
  Claude Code and submitted as finished scripts rather than by the production
  pipeline. They are used only for models with no pipeline-written episode.
## Selection rule
Per canonical writer model, from aired English episodes with a transcript (test
episodes, translations and `audio_eval` specials excluded; records that name no
model — `manual-script`, `manual-generation`, `unknown`, `none`, `openrouter/mixed`
— skipped):
1. Pool = the first non-empty of: pipeline-written with at least 1,500 words;
   pipeline-written of any length; offline-written with at least 1,500 words;
   offline-written of any length (the `pool` column says which).
2. Picks, by publication date within the pool: the **earliest**, the **median-date**
   one and the **latest**. A model with one or two eligible episodes gets one or two.
The build is deterministic. It is rebuilt on demand by
[`scripts/build_model_chronicle.py`](scripts/build_model_chronicle.py) (a copy of the
exact code ships in this repo) from the production database; hand edits on the Hub
are overwritten.
## Models
| Canonical id | Name | Provider | Era (first → last aired) | Episodes | Picks | Pool |
|---|---|---|---|---|---|---|
{chr(10).join(models)}
## Columns
| Column | Description |
|---|---|
{cols}
Canonicalisation: `anthropic/claude-sonnet-4.6` and `claude-sonnet-4-6` are the same
model under two spellings and share `model_canonical = claude-sonnet-4-6`.
`deepseek-chat` is kept as its own id here, as in the full corpus; those episodes say
on air that DeepSeek v3.2 wrote them.
## Use
```python
from datasets import load_dataset
ds = load_dataset("My-Weird-Prompts/model-chronicle", split="train")
```
The writing models' providers set their own terms on using model output, including
for training other models; check them before fine-tuning on these scripts. For a
fine-tuning set curated with that in mind, contact show@myweirdprompts.com.

	# My Weird Prompts — Model Chronicle

	My Weird Prompts is an AI-generated podcast: every episode's dialogue is written by
	a large language model, and the model that writes it has changed many times since
	November 2025. The back catalogue is therefore a chronicle of how frontier models
	evolved, with each era's writer on air. This dataset is a small, curated slice of it —
	up to three aired scripts per writer model — so anyone can read eras side by side
	("Gemini 2.5 Flash vs DeepSeek V4 Pro vs GPT-6.1 Sol") without downloading the full
	corpus.

	{len(rows)} scripts from {n_models} writer models, built {built_at}.

	- Site hub, with the leaderboard and writer history: <https://myweirdprompts.com/benchmark>
	- Full corpus (every episode, turns, text statistics): [`My-Weird-Prompts/transcripts`](https://huggingface.co/datasets/My-Weird-Prompts/transcripts)
	- Browse and filter every transcript by model: [`My-Weird-Prompts/transcripts-explorer`](https://huggingface.co/spaces/My-Weird-Prompts/transcripts-explorer)
	- Controlled, same-prompt benchmark of candidate writers: <https://github.com/My-Weird-Prompts/eval>

	## Read this before comparing

	These are not same-prompt comparisons. Each script answers whatever listener or
	host prompt was on the queue that day; topics, lengths and episode formats differ.
	For like-for-like scoring of writers on identical briefs, use the eval repo above.

	The model is not the only thing that changed between eras:

	- The system-prompt template changed with the model, twice. In the full
	catalogue (measured 2026-09-22 over 5,332 episodes), template 3.5 → 4.0 landed on
	the April 2026 Gemini → DeepSeek switch, and 4.0 → 4.1 on the September 2026
	DeepSeek V4 Pro → V4.1 Flash switch. A difference between those eras is never
	attributable to the model alone. `prompt_version` is included per row; null
	means not recorded (before March 2026), not "none".
	- A deterministic verbal-tic cleanup pass runs after generation and deletes
	stock phrasings (conjunction openers, sycophantic openers, echo handoffs), so
	the aired text is not the raw model output. The full corpus counts what it removed
	per episode (`tic_*` columns).
	- Episode length moved: median length rose from about 3,000 words (2025) to
	about 4,200 (2026), so length-sensitive measures (n-gram repetition, compression)
	trend partly with length.
	- Some eras are a few days long. The March 2026 and October 2026 bake-offs aired
	one to a handful of episodes per candidate; those share that week's prompts, so
	anything topic-linked in them is subject matter, not style. `model_episode_count`
	shows how much each model actually wrote.
	- Offline scripts (`written = offline`, {n_offline} rows here) were written in
	Claude Code and submitted as finished scripts rather than by the production
	pipeline. They are used only for models with no pipeline-written episode.

	## Selection rule

	Per canonical writer model, from aired English episodes with a transcript (test
	episodes, translations and `audio_eval` specials excluded; records that name no
	model — `manual-script`, `manual-generation`, `unknown`, `none`, `openrouter/mixed`
	— skipped):

	1. Pool = the first non-empty of: pipeline-written with at least 1,500 words;
	pipeline-written of any length; offline-written with at least 1,500 words;
	offline-written of any length (the `pool` column says which).
	2. Picks, by publication date within the pool: the earliest, the median-date
	one and the latest. A model with one or two eligible episodes gets one or two.

	The build is deterministic. It is rebuilt on demand by
	[`scripts/build_model_chronicle.py`](scripts/build_model_chronicle.py) (a copy of the
	exact code ships in this repo) from the production database; hand edits on the Hub
	are overwritten.

	## Models

	\| Canonical id \| Name \| Provider \| Era (first → last aired) \| Episodes \| Picks \| Pool \|
	\|---\|---\|---\|---\|---\|---\|---\|
	{chr(10).join(models)}

	## Columns

	\| Column \| Description \|
	\|---\|---\|
	{cols}

	Canonicalisation: `anthropic/claude-sonnet-4.6` and `claude-sonnet-4-6` are the same
	model under two spellings and share `model_canonical = claude-sonnet-4-6`.
	`deepseek-chat` is kept as its own id here, as in the full corpus; those episodes say
	on air that DeepSeek v3.2 wrote them.

	## Use

	```python
	from datasets import load_dataset
	ds = load_dataset("My-Weird-Prompts/model-chronicle", split="train")
	```

	The writing models' providers set their own terms on using model output, including
	for training other models; check them before fine-tuning on these scripts. For a
	fine-tuning set curated with that in mind, contact show@myweirdprompts.com.
