Fable 5's included-in-subscription window ends July 7, 2026. Here's exactly how usage credits work, what Fable 5 costs after the switch, and how to set spend limits so an agent doesn't drain your balance.
Anthropic's agentic mid-tier Claude Sonnet 5 vs OpenAI's flagship GPT-5.5: benchmarks, pricing, and when to use which for agents and reasoning.
Claude Sonnet 5 is the agentic mid-tier workhorse; Opus 4.8 is Anthropic's reasoning flagship. When to use which by workload, cost, and speed.
Anthropic's most agentic Sonnet yet, launched June 30, 2026. Full benchmark table, real pricing (including the tokenizer catch), availability, and honest verdicts vs Sonnet 4.6, Opus 4.8, GPT-5.5 and Gemini.
Claude Fable 5 is back online as of July 1, 2026, after the U.S. lifted its export-control order. Here's what changed, how Anthropic brought it back, and how to access it.
Moonshot's open-weights Kimi K2.7 Code goes head-to-head with Anthropic's Claude Opus 4.8. Architecture, benchmarks (and where they don't exist yet), per-task cost, agentic strength, self-host paths, and a clean per-workload verdict.
GLM 5.2 ships 1M-token context and MIT open weights on a flat subscription. Claude Opus 4.8 stays the agentic-coding benchmark at premium per-token pricing. We compare cost, agentic strength, self-hosting and pick a winner per workload.
Anthropic's first publicly available Mythos-class model, released June 9, 2026. Third-party benchmarks, pricing, context window, availability, the safety reroute to Opus 4.8, and how it compares to GPT-5.5 and Gemini 3.5.
Anthropic launched Claude Opus 4.8 on May 28, 2026: SWE-bench Pro 69.2%, GDPval Elo 1890 (+121 over GPT-5.5), Fast mode 3x cheaper than 4.7, dynamic workflows for hundreds of parallel subagents. Pricing unchanged at $5/$25 per 1M. Full launch breakdown.
How senior engineers wire Claude Skills and MCP servers together in 2026: SKILL.md format, the MCP 2025-11-25 spec, real integration patterns for code review, database access, and incident response.
Claude Mythos, Opus 4.7, and GPT-5.5 shipped within three weeks of each other in April 2026. We break down which frontier model wins on coding, reasoning, vision, cost, and which one your team should actually pick.
Claude Sonnet 4.8 is not announced as of May 19, 2026. The honest status check: what's shipping, where the rumor came from, and what to run now.
How to set per-task token, cost, step, and time budgets when running Claude Opus 4.7 as an agentic coder — plus team-level caps that keep monthly burn predictable.
The 2026 head-to-head: Grok 4.3 vs Claude Opus 4.7 vs Gemini 2.5 Pro on SWE-bench, LiveCodeBench, pricing, real coding workflows, IDE harnesses, and a clear pick-by-job-to-be-done framework.
Gemini CLI vs Claude Code in May 2026: open source vs proprietary, free 1,000 req/day vs $20/mo, SWE-bench scores, install, multimodal workflows, and a clear decision framework.
