Grok 4.3 landed on Amazon Bedrock June 15, 2026 as the cheapest US-lab frontier reasoning model. The pricing, Mantle endpoint gotchas, and enterprise risks.

Sakana Fugu wraps a pool of frontier models behind one orchestration API. We cover the two models, vendor benchmarks, pricing, and the export-control angle.

Claude Fable 5 leads the benchmarks; GPT-5.5 costs half as much and owns Codex. We compare coding, knowledge work, long context, and cost to find the fit.

Anthropic shipped its strongest model as two products: Fable 5, generally available with safeguards, and restricted Mythos 5. Benchmarks, pricing, the catch.

We compare Claude Opus 4.8 and GPT-5.5 on coding, agents, reasoning, and real cost — including where GPT-5.5 still wins and which model fits which job.

Alibaba's Qwen 3.7 Max ships with 1M context, $2.50/$7.50 pricing, and benchmarks topping Opus 4.6 on Terminal-Bench, SWE-Bench Pro, and MCP-Atlas.

The Q2 2026 agentic-AI quarterly — model releases, MCP adoption, enterprise deployments, funding, regulatory shifts. 12 charts on where the market moved.

DeepSeek-V4 ships April 24, 2026 as open-weight MoE: Pro (1.6T/49B active) and Flash (284B/13B), 1M context, 27% FLOPs and 10% KV cache vs V3.2.

MoE choices powering 2026 frontier models compared — total vs active params, routing strategies, sparsity ratios, and the downstream cost implications.

Per-query energy and water data for frontier models, training-vs-inference split, and emissions per million tokens. Methodology and trend analysis.

Head-to-head: GPT-5.5 and Claude Opus 4.7 on agentic coding, computer use, 1M context, pricing, and the right model for each production workload.

OpenAI's GPT-5.5 ships April 23, 2026 with 1M context, Thinking and Pro variants, 82.7% Terminal-Bench, and same latency as GPT-5.4. Pricing inside.

Side-by-side input, output, cached, and batch pricing for 30 frontier and open-weight models across 12 providers. Updated April 2026 with 200+ price points.

We measured low/medium/high reasoning effort across 5 frontier models on math, code, and analysis. Quality lift, latency tax, and cost-per-correct-answer data.

Cross-model hallucination rates on factual recall, citation accuracy, and code reference. 5,000 prompts tested across 5 frontier models with confidence bands.

MCP tool-call success across 12 task types — search, file ops, data, calendar, email. Pass-rate, retry-rate, and cost-to-completion for 5 frontier AI models.

Time-to-first-token and tokens-per-second across 30 model+provider pairings. P50/P95 numbers, regional spread, and how reasoning-mode tax cold latency budgets.

Why $/token is the wrong unit and $/successful-task is the right one. Formulas, worked examples across 6 task families, and a downloadable scoring template.

Claude Opus 4.7 scores 64.3% on SWE-bench Pro with 2576px vision, xhigh effort, and same Opus 4.6 pricing. Full benchmark and migration guide.

The Frontier Model Release Velocity Index tracks new-model launch rates per provider — OpenAI, Anthropic, Google, Alibaba, Zhipu. Q2 2026 trajectory data.

Preview of Q2 2026 AI model releases. DeepSeek V4 at ~1T parameters, GPT-5.5 Spud with pretraining done, and Grok 5 expected by mid-2026. Timeline and specs.

Twelve AI models launched in a single week of March 2026 from OpenAI, Google, Mistral, xAI, and more. Developer guide to capabilities, pricing, and selection.

Google's Gemini 3.1 Flash-Lite costs $0.25 per million tokens and outperforms GPT-5 Mini on key benchmarks. Complete pricing and performance comparison guide.

GPT-5.4 ships three variants: Standard, Thinking, and Pro. Native computer use, 1M context, tool search, and 33% fewer factual errors. Complete guide.

Three-way frontier model comparison: GPT-5.4 vs Claude Opus 4.6 vs Gemini 3.1 Pro benchmarks, agentic AI capabilities, pricing, and which model wins.
