The new self-managed-context skill turns context control into a concrete harness: protect the task and system instructions, make the remaining context editable, then reread it after each tool call. Its small comparison makes the trade-off testable, but replicate it on a longer workload before treating the 3/3 result as general.

Coding-agent performance now comes with a visible cost curveArtificialAnlys

This week Claude Sonnet 5.5, GPT-6.1 Sol and Gemini 4 Argon all launched near the top of the Coding Agent Index leaderboard, but each has a different balance of performance and cost The Artificial Analysis Coding Agent Index measures agents (a combination of model and harness) across three agentic coding evaluations. ➤ Claude Sonnet 5.5 (max) in Claude Code takes the top spot at 68, but also has the highest measured cost per task: $14.19 ➤ Gemini 4 Argon (high) in Antigravity CLI scores 64 at $5.84 per task - less than half of Sonnet 5.5’s cost. Note, this uses Google’s promotional pricing, and Argon is not yet publicly available ➤ GPT-6.1 Sol (xhigh) in Codex scores 63 at $1.04, roughly one sixth of Argon’s cost
The reported leaderboard is a comparison of agent-plus-harness pairs, not models in isolation. It makes per-task cost and harness choice part of the evaluation decision; the promotional pricing and unavailable status noted for one entrant still require workload-specific tests.

Higher yields do not settle the policy question
Logan’s framework makes the source of higher yields decisive: policy-path yields do not replace further tightening, while higher term premiums can. The St. Louis Fed put the 30-year fixed mortgage rate at 7.3%, the highest since November 2023.
Dallas Fed President Lorie Logan says the Fed likely will need to raise rates by at least another 50 bps to ensure inflation doesn’t settle above the central bank’s 2% goal. Logan said those additional increases, together with September’s, would merely reverse the three cuts…
Dallas Fed President Lorie Logan says the Fed likely will need to raise rates by at least another 50 bps to ensure inflation doesn’t settle above the central bank’s 2% goal. Logan said those additional increases, together with September’s, would merely reverse the three cuts the Fed made last year. She said the Fed needs to set interest rates at a modestly restrictive level, a threshold that remains uncertain and could require even more increases. Logan drew a distinction on the run-up in bond yields. To the extent higher Treasury yields reflect expectations of a more aggressive Fed, those increases “don’t do our work for us,” she said. But if the increase in yields is driven by rising term premiums, or the extra compensation investors demand to hold longer-term debt, the moves “can slow the economy, reducing the need to tighten monetary policy.” https://t.co/7CR3iduR5s
Average fixed mortgage rates rose in the week ending Oct. 1, to 7.3% for the 30-year and 6.6% for the 15-year, the highest levels since November 2023 https://t.co/ygHqJHmb3k https://t.co/ra3t02D5OQ

Export controls are a portfolio exposure, not only a trade headlineMatteo Crosignani, Lina Han, and Marco Macchiavelli, Federal Reserve Bank of New York
Using supply-chain links and holdings for more than 5,000 funds, the authors find that U.S. suppliers to newly controlled Chinese customers lost 3.6% cumulatively around announcements. A one-standard-deviation rise in exposure was associated with a 22-basis-point monthly return decline, making customer geography a portfolio-monitoring input rather than a trade-policy footnote.

In September, the nation’s unemployment rate ticked up to 4.2% from the previous month’s 4.1%. The underemployment rate, which tracks those marginally attached to the labor force and people working part time for economic reasons, declined slightly, to 7.6% https://t.co/ihVIQ57wlv https://t.co/XvnVAwtX3E
September payrolls rose only 29,000, while July and August were revised down a combined 60,000; unemployment was 4.2%. Participation held at 61.8% and private hourly earnings were 3.0% higher year over year, so the release is a slowing data point rather than an all-clear on labor costs.
