5. Best Practices Released for Optimizing Claude Code Token Costs
A set of optimization guidelines has been released to help developers manage token costs during Claude Code terminal sessions. Because Claude Code relies heavily on prompt caching to keep costs down, developers are advised to avoid mid-session setting changes, use built-in commands like /clear and /compact, and restrict bash output lengths to prevent unnecessary context bloat.
- • Claude Code sessions are billed per token, with prompt caches typically expiring after one hour.
- • Changing settings like the model or effort level mid-session invalidates the prompt cache.
- • Users can use /clear between tasks and /compact to summarize long conversations and free up context.
- • Attaching files via @-mentions in the initial request prevents redundant Read tool calls.
- • Configuring BASH_MAX_OUTPUT_LENGTH or using quiet flags prevents large command outputs from bloating the context.
- • Subagents can be used to isolate noisy tasks into separate context windows.
Developers using Claude Code can immediately lower their daily API costs by structuring their terminal sessions to preserve prompt caches and limit command outputs.
6. Bluesky Launches Jetstream v2 and Rebuilt TypeScript SDK
Bluesky has overhauled its developer ecosystem by launching Bluesky Protocol Services and releasing Jetstream v2. The updated data streaming protocol features a Network Replay capability to prevent data gaps during stream transitions, supported by newly written, fully-typed TypeScript and Go SDKs that simplify event handling and deduplication.
- • Bluesky has launched Bluesky Protocol Services, a new documentation hub replacing docs.bsky.app.
- • Jetstream v2 introduces Network Replay, allowing developers to access historical records and transition to a live stream without gaps.
- • Jetstream v2 requires an API token for archive requests, while the live tail remains open and unauthenticated.
- • New Jetstream SDKs for TypeScript and Go assist with event reconnection, deduplication, and decoding.
- • The Bluesky TypeScript SDK has been rebuilt on top of @atproto/lex to provide full typing and eliminate legacy code paths.
Developers building social or real-time data applications can consume the AT Protocol firehose with zero-gap historical transitions and fully-typed TypeScript SDKs.

12. Anthropic Joins Price War with Claude Opus 5 Cuts
Anthropic has reduced the cost of its Claude Opus 5 model by 50%, marking a significant escalation in the ongoing API price war. This move follows OpenAI's recent 80% reduction for the GPT-5.6 Luna model, contributing to an industry-wide token price drop of nearly 25% since mid-July. These aggressive cuts reflect a strategic shift by US labs to counter the growing adoption of cost-effective Chinese models by enterprise customers.
- • Anthropic has launched Claude Opus 5 at half the price of its predecessor.
- • OpenAI previously reduced GPT-5.6 Luna pricing by 80 percent.
- • US labs are shifting enterprise customers from flat subscriptions to usage-based billing.
- • Competition from Chinese AI providers is driving the current industry-wide price reductions.
The rapid downward trend in API costs, now encompassing both OpenAI and Anthropic, makes frontier-class models increasingly accessible for production-scale agentic workflows.
