The environment section rendered "Model family: Claude Opus 4.6" for
every Anthropic model, so claude-opus-5-5, claude-sonnet-4-6, and any
other Claude model told users it was Opus 4.6.
Render a neutral "Claude" family label followed by the resolved model
ID, and rebuild the system prompt on /model so the line follows a
mid-session switch instead of keeping the startup model.
Models from the OpenAI-compatible providers fell back to
default_sonnet_tier ($3/$15 per MTok), so e.g. gpt-5.4-nano was
estimated at 15x its input price and qwen-plus at about 26x.
Add a table of published rates keyed by model id, matching dated
snapshots and -latest aliases:
- OpenAI standard tier for current gpt-6 / gpt-5.x / gpt-4.1 / gpt-4o
and o-series models (Responses-only pro models are omitted).
- xAI grok-4.x and grok-build. Slugs retired on 2026-05-15 (grok-3,
grok-4-0709, grok-4-fast-*, grok-4-1-fast-*) are billed at grok-4.3
rates, and grok-code-fast-* is served as grok-build.
- DashScope qwen-max, qwen-plus, qwen-flash and kimi-k2.5 at China
(Beijing) rates, which is claw's default DashScope endpoint, with
non-thinking output and the 20% implicit-cache hit rate.
Long-context and higher input tiers use the base rate because usage is
aggregated across requests.
std::env::vars() panics on any non-UTF-8 value. zsh exports a metafied
$_ when the command path contains non-ASCII characters (e.g. 下載), so
claw panicked on startup. Use vars_os() and skip entries that are not
valid UTF-8.
* fix(runtime): update model pricing table to current rates
Align pricing_for_model with the published Anthropic pricing table:
- default_sonnet_tier was $15/$75 (the old Opus rate); it is now the
Sonnet 4.x rate of $3/$15, which is what the `sonnet` alias resolves to.
- Add Sonnet 5 / 5.5, Haiku 5.5, Haiku 3.5, and Fable / Mythos rates.
- Opus 4.5+ is $5/$25 and Opus 5.5 is $4/$20; Opus 4/4.1 keep the $15/$75
tier they are still billed at on Bedrock and Google Cloud.
Versions are parsed from the model id so dated, provider-prefixed, and
Vertex-style ids resolve to the right tier. Haiku 5.5's >100K-token tier
is not modeled because usage is aggregated across requests.
* fix(runtime): add DeepSeek API pricing
DeepSeek models fell back to default_sonnet_tier ($3/$15 per MTok),
overestimating V4 Flash by about 10x on input and 12x on output.
Price the ids served by the DeepSeek API at peak rates: deepseek-v4-pro
at $1.32/$3.96, and deepseek-flash, deepseek-v4-flash and the retired
deepseek-chat / deepseek-reasoner aliases at $0.30/$1.20. Off-peak usage
is billed at half. Other DeepSeek models on third-party hosts keep the
default because their prices vary by host.
push_output_block recorded a thinking event at content_block_start (an
empty placeholder) and the stream loop recorded the full block again at
content_block_stop. The empty duplicate was replayed on the next request
and rejected with 400 "each thinking block must contain thinking".
Only emit the event from the non-streaming path.
