The one thing

01

DeepSeek peak/off-peak API rates are live as of 16 Aug 16:00 UTC.

Peak hours are 01:00–04:00 and 06:00–10:00 UTC; all other hours are off-peak at half of peak.¹ Flash peak cache-miss input $0.44 / 1M and output $1.32 / 1M (off-peak $0.22 / $0.66). Pro peak $1.32 / $3.96 (off-peak $0.66 / $1.98). Cache-hit input is a separate, much lower tier.¹

Issue 009 printed the notice before the cutover. The cutover held. Model versions on the same page: Flash-0731, Pro-0813.¹

VERDICT · BREAKING — Meter DeepSeek by UTC hour. Prefer off-peak for batch and long loops; pin Pro-0813 or Flash-0731 so a silent version cell cannot surprise you.

Deeper — hours and pins

Peak: 01:00–04:00 and 06:00–10:00 UTC only.¹
Concurrency: Flash 2500, Pro 500.¹
OpenAI- and Anthropic-format base URLs unchanged; Responses API and tool calls still listed.¹

Use it

openai-agents-python 0.21.1 · model call timeouts + sandbox controls

Model call timeouts land in core. Sandboxes get run-scoped working directories, optional Docker network disable, and Modal resource options. Approval decisions honor exact matches; Responses usage counting and MultiProvider cleanup fix edge failures.²

The conversation

01

The claim — including ours

The cheap Chinese API most of this desk already meters now bills by UTC hour, and the same vendor opened its in-house harness as a plugin runtime you can npx.¹³

From the floor

DeepSeek pricing footnote (1)Vendor, dated
"Off-peak rates are half of the peak rates. Peak hours are 01:00 - 04:00 and 06:00 - 10:00 UTC (all other hours are off-peak)."¹

"DeepSeek Harness is currently in developer preview and is iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES."³

Our take

Budget DeepSeek by the clock. Try dsh only if you build harnesses — pin nothing production to a preview that promises breaks.

GitHub releases: 28 watchlist repos, sweep_complete true, authenticated, 5 in-window (3 llama.cpp nightlies collapsed). Vendor feeds: 12 sources, sweep_complete true, 1 in-window (Anthropic critical auth outage 0.6h, resolved). X accounts (90) and X keyword digests last collected 05:30 UTC 16 Aug (~24.5h old) — background only; no 17 Aug X digest in-repo. Reddit: fresh pulse (6 subreddits, 11 posts). HN: Claude outage thread. arXiv not swept. Weekend gap after #009 (no 15–16 Aug issues).

Anthropic critical auth outage (0.6h) across claude.ai, API, Claude Code, Cowork. Resolved weather with duration. No product change.

llama.cpp b10452–b10455 nightlies. SYCL optimizer ops and chat content-type refactors. Not a ship decision.

browser-use 0.13.8 patch pile. Cerebras IDs, Anthropic tool-arg recovery, agent guards. Collapsed.

End of feed. That is everything from the window worth your time.
Next issue tomorrow, 06:00 UTC — and if nothing ships, it will say so in two hundred words.

Still developingDeepSeek peak/off-peak is live (this issue). Ultrafast expands with capacity (issue 009). Muse Glimmer runtimes still rolling (issue 006). Sonnet 5 docs lag $2/$10 (issue 006). MAI-Code-1-Flash → 1.1-Flash closes 10 Sept. DeepSeek Harness stays preview.
